Answers

Answer 1

Answer:

11.2896π square units

Step-by-step explanation:

A rhombus is a quadrilateral (a four-sided polygon) with sides of equal length. The diagonals of a rhombus bisect each other at right angles.

Let the vertices of the rhombus be A, B, C and D.

As the diagonals of rhombus ABCD are 3.5 and 12 units, then AC = 3.5 and BD = 12.

Place a circle centered at vertex C and tangent to sides AD and AB (refer to attachment 1).

The diagonals divide the rhombus into 4 congruent right triangles with legs measuring 1.75 units and 6 units.

Let the point of intersection of the two diagonals be M.

Use the tangent trigonometric ratio to find the measure of angle MAB in triangle AMB (refer to attachment 2).

[tex]\begin{aligned} \tan (\theta)&=\dfrac{\sf opposite \;side}{\sf adjacent\;side}\\\\ \implies \tan (MAB)& =\dfrac{6}{1.75}\\\\&=\dfrac{24}{7}\\\\\angle MAB&=\arctan\left(\dfrac{24}{7}\right)\end{aligned}[/tex]

The tangent of a circle is perpendicular to its radius.

Therefore, the radius of the circle with center C is a straight line from point C perpendicular to line segment AB (labelled in green in attachment 3). The point of intersection of the radius and side AB is E.

By drawing the radius (CE), we have created another right triangle, AEC, where its hypotenuse is the shortest diagonal of the rhombus (AC), its longest leg is the radius (CE), and the angle opposite the radius is angle MAB.

Using this information and the sine trigonometric ratio, we can calculate length of the radius of circle C:

[tex]\begin{aligned}\sin(\theta)&=\sf \dfrac{opposite\;side}{hypotenuse}\\\\\implies \sin\left(MAB\right)&=\dfrac{CE}{AC}\\\\\implies \sin\left(\arctan\left(\dfrac{24}{7}\right)\right)&=\dfrac{r}{3.5}\\\\0.96&=\dfrac{r}{3.5}\\\\r&=3.36\; \sf units\end{aigned}[/tex]

Now we have calculated the exact radius of the circle, we can find its area by substituting the value of r into the area of a circle formula:

[tex]\begin{aligned}\textsf{Area of a circle}&=\pi r^2\\&=\pi (3.36)^2\\&=11.2896 \pi\; \sf square \;units\end{aligned}[/tex]

Therefore, the exact value of the circle area is 11.2896π square units.

Note: Attachment 4 is the circle centered at the other 3 vertices of the rhombus. All circles are congruent and therefore have the same area.

In her geology class, Nora learned that quartz is found naturally in a variety of colors. Nora's teacher has a giant box of colorful quartz pieces that he and his students have collected over the years. Nora picks a piece of quartz out of the box, records the color, and places it back in the box. She does this 18 times and gets 3 purple, 2 yellow, 5 white, and 8 pink quartz pieces.
Based on the data, what is the probability that the next piece of quartz Nora picks will be yellow?
Write your answer as a fraction or whole number.

Answers

The probability that Nora will pick a yellow quartz piece on the next selection is 1/9.

To calculate the probability of picking a yellow quartz piece on the next selection, we need to analyze the frequency of yellow quartz pieces relative to the total number of recorded quartz pieces.

Out of the 18 quartz pieces Nora picked, only 2 were yellow.

To find the probability, we divide the number of yellow quartz pieces by the total number of pieces recorded:

Probability = Number of yellow quartz pieces / Total number of recorded pieces

The number of yellow quartz pieces is 2, and the total number of recorded pieces is 18.

So the probability can be calculated as:

Probability = 2 / 18

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2 in this case:

Probability = 1 / 9

It's important to note that this probability assumes the picking process is random and that the distribution of colors in the giant box of quartz pieces remains constant over time.

Measure the diameter of tin in mm and write down the real diameter in mm​

Answers

The tin's actual diameter is 250 mm.

What do you mean by diameter?

A circular object, like a circle or sphere, has a diameter, which is the length of a straight line that runs through its centre. It is the separation between two locations on an object's edge that are the furthest apart and traverse the object's centre.

Here, if the tin's diameter in the illustration is 10 cm, the actual tin's diameter can be determined as follows:

Real Diameter is 2.5 times the image diameter.

2.5 x 10 cm is the actual diameter.

Real diameter is 25 cm.

To translate the actual dimension to millimetres (mm), we can multiply by 10:

Actual Diameter multiplied by 10 to convert to mm

Real Diameter = 25 cm x 10 in mm.

Actual Diameter is 250 millimetres.

As a result, the tin's actual diameter is 250 mm.

If f=(x) is an exponential function where f(1)=8 and f(10.5)=72 then find the value of f(3.5)

Answers

Answer: We know that the function f(x) is an exponential function. An exponential function can be written in the form:

f(x) = a * b^x

where:

a = the initial value (when x = 0)

b = the base of the exponential function

x = the independent variable

To find the values of a and b, we can use the given information:

f(1) = 8, so:

8 = a * b^1

8 = a * b

f(10.5) = 72, so:

72 = a * b^10.5

We can now use the first equation to solve for a:

a = 8/b

Substituting this value into the second equation, we get:

72 = (8/b) * b^10.5

Simplifying:

72 = 8 * b^9.5

9 = b^9.5

b = 9^(1/9.5)

b = 1.4608 (approx.)

Substituting the values of a and b into the exponential function, we get:

f(x) = 8 * 1.4608^x

Now we can find f(3.5):

f(3.5) = 8 * 1.4608^3.5

f(3.5) = 8 * 6.2797

f(3.5) = 50.2376 (approx.)

Therefore, f(3.5) is approximately equal to 50.24.

Find the coordinates of the orthocenter of AXYZ with vertices X(-9,5), Y(-6, 8), and Z(-6,3). whoever answers gets brainliest​

Answers

Answer:

The orthocenter of triangle XYZ is (-6,4).

Step-by-step explanation:

To find the orthocenter of triangle XYZ, we need to first find the altitudes of the triangle.

The altitude of a triangle is a line that passes through a vertex of the triangle and is perpendicular to the opposite side.

Let's find the equation of the line passing through X(-9,5) and perpendicular to YZ. The slope of YZ is (8-3)/(-6+6) = 5/0, which is undefined. Therefore, YZ is a vertical line passing through the point (-6,3). The equation of this line is x=-6.

The line passing through X(-9,5) and perpendicular to YZ must be a horizontal line passing through X. Therefore, the equation of this line is y=5.

Similarly, the equation of the line passing through Y(-6,8) and perpendicular to XZ is x=-6.

The equation of the line passing through Z(-6,3) and perpendicular to XY is y=3.

Now, we need to find the intersection of these lines to find the vertices of the triangle's altitude.

The altitude from X passes through the point X(-9,5) and is perpendicular to the line YZ with equation x=-6. Therefore, the intersection of the altitude from X and YZ must have x-coordinate -6. Since the equation of the altitude from X is y=5, we get the point of intersection as (-6,5).

Similarly, the altitude from Y passes through the point Y(-6,8) and is perpendicular to the line XZ with equation x=-6. Therefore, the intersection of the altitude from Y and XZ must have x-coordinate -6. Since the equation of the altitude from Y is y=8, we get the point of intersection as (-6,8).

The altitude from Z passes through the point Z(-6,3) and is perpendicular to the line XY with equation y=3. Therefore, the intersection of the altitude from Z and XY must have y-coordinate 3. Since the equation of the altitude from Z is x=-6, we get the point of intersection as (-6,3).

Now that we have the vertices of the altitudes, we can find the equation of the lines passing through them.

The line passing through (-6,5) and (-6,8) is the line x=-6.

The line passing through (-6,5) and (-6,3) is the line y=4.

The line passing through (-6,8) and (-6,3) is the line x=-6.

Now, we find the intersection of the lines x=-6 and y=4. The intersection point is (-6,4).

Therefore, the orthocenter of triangle XYZ is (-6,4).

At a restaurant you only have $30 to spend on dinner. In addition to the cost of the meal you must pay a 8% sales tax and leave a 20% tip. What is the most expensive item you can order?​

Answers

Answer: Let's break down the total cost of dinner into three components: the cost of the meal itself (M), the sales tax (T), and the tip (P).

We know that the sales tax is 8% of the meal cost, so we can write:

T = 0.08M

We also know that the tip is 20% of the total cost, which is the sum of the meal cost and the sales tax, so we can write:

P = 0.20(M + T) = 0.20(M + 0.08M) = 0.20(1.08M) = 0.216M

Finally, we know that the total cost of dinner must be no more than $30, so we can write:

M + T + P ≤ 30

Substituting the expressions for T and P that we derived earlier, we get:

M + 0.08M + 0.216M ≤ 30

Simplifying and solving for M, we get:

1.296M ≤ 30

M ≤ 23.15

Therefore, the most expensive item you can order is $23.15 or less (before tax and tip) to stay within your budget of $30.

The tensions in the string are approximately 37.5 lb and 57.39 lb for T1 and T2, respectively.

Describe Tension?

Tension is the force that is transmitted through a string, rope, cable, or any other object that is pulled taut by a force. It is a pulling force that is exerted on an object by the string or cable that is attached to it. Tension is a scalar quantity, meaning that it has a magnitude but no direction.

The tension in a string or cable depends on several factors, including the strength and stiffness of the material, the angle at which the string is attached to the object, and the amount of force applied to the string. In general, the tension in a string is equal to the force applied to the string, divided by the cross-sectional area of the string.

To find the tensions T1 and T2 in the string, we can use trigonometry and the fact that the weight is in equilibrium (i.e., not moving).

First, we can use the fact that the weight is in the middle of the string to split the weight into two equal components, one pulling on each end of the string.

The weight component pulling on T1 can be found by multiplying the weight by the sine of the angle between T1 and the horizontal:

W1 = (75 lb) * sin(50°)

W1 ≈ 57.39 lb

Similarly, the weight component pulling on T2 can be found by multiplying the weight by the sine of the angle between T2 and the horizontal:

W2 = (75 lb) * sin(30°)

W2 ≈ 37.5 lb

Since the weight is in equilibrium, the tensions in the string must be equal and opposite to these weight components:

T1 = W2 ≈ 37.5 lb

T2 = W1 ≈ 57.39 lb

Therefore, the tensions in the string are approximately 37.5 lb and 57.39 lb for T1 and T2, respectively.

What is system of equation?

A set or group of equations that you solve all at once is referred to as a "system" of equations. The simplest linear system is one with two equations and two variables. Linear equations are simpler than non-linear equations because they graph as straight lines.

Given equations : 5x+y=7

                             20x+2=y

We can solve it by using substitution method:

Now, we have 5x+y=7

it can be written as,

         y = 7 - 5x .... equation 1

Similarly, we have 20x+2=y

can be written as,

           y = 20x+2 ..... equation 2

Subtracting equation 1 from equation 2

we get,  20x+2 - ( 7 - 5x ) = 0

             20x + 5x + 2 - 7 = 0

             25x = 5

               x = 1/5

Putting x=1/5 in equation 1,

we get, y = 20 × 1/5 + 2

A cube root function's graph is a curve that extends to both positive and negative infinity from its origin. An example of a power function is the cube root function, which is described by the equation y = ∛x, where the cube root sign (∛) stands for the inverse of raising a number to the power of three.

The cube root function yields a positive value of y when x is a positive integer. As an illustration, if x = 8, then y = √8 = 2. The cube root function, on the other hand, yields a negative value of y if x is a negative number. As an illustration, if x = -27, y = ∛(-27) = -3

To graph a cube root function, we can create a table of values by choosing several values of x and then calculating the corresponding values of y using the equation y = ∛x. Once we have several points, we can plot them on a coordinate plane and then connect them with a smooth curve to get the graph of the function.

Gauss Jordan elimination method step by step 0.99x-0.04y-0.2z=4
-0.1x+0.97y=6
-0.2x-0.01y+0.96z=3

Answers

To solve the system of equations using the Gauss-Jordan elimination method, we can use the following steps:

Step 1: Write the augmented matrix for the system of equations.

The augmented matrix for the given system of equations is:

```
[ 0.99 -0.04 -0.2 | 4 ]
[-0.1 0.97 0 | 6 ]
[-0.2 -0.01 0.96| 3 ]
```

Step 2: Use row operations to transform the matrix into row echelon form.

We can start by using row operations to create zeros below the first entry in the first column:

R2 = R2 + 0.1010R1
R3 = R3 + 0.2020R1

The new matrix is:

```
[ 0.99 -0.04 -0.20 | 4 ]
[ 0 0.9696 -0.0196| 6.04 ]
[ 0 -0.0602 0.9192| 3.808 ]
```

We can now use row operations to create a zero in the second row and second column:

R3 = R3 + 0.0620R2

The new matrix is:

```
[ 0.99 -0.04 -0.20 | 4 ]
[ 0 0.9696 -0.0196| 6.04 ]
[ 0 0 0.9142| 4.0088 ]
```

Step 3: Use row operations to transform the matrix into reduced row echelon form.

We can start by using row operations to create a one in the third row and third column:

R3 = (1/0.9142)R3

The new matrix is:

```
[ 0.99 -0.04 -0.20 | 4 ]
[ 0 0.9696 -0.0196| 6.04 ]
[ 0 0 1 | 4.3852 ]
```

We can now use row operations to create zeros above and below the pivot in the third column:

R1 = R1 + 0.20R3
R2 = R2 + 0.0196R3

The new matrix is:

```
[ 0.99 -0.04 0 | 4.87704 ]
[ 0 0.9696 0 | 6.1304 ]
[ 0 0 1 | 4.3852 ]
```

We can now use row operations to create zeros above and below the pivot in the second column:

R1 = R1 + 0.0412R2

The new matrix is:

```
[ 0.99 0 0 | 5.0038 ]
[ 0 0.9696 0 | 6.1304 ]
[ 0 0 1 | 4.3852 ]
```

Step 4: Write the solution in terms of the variables.

The reduced row echelon form of the augmented matrix corresponds to the system of equations:

```
0.99x = 5.0038
0.9696y = 6.1304
z = 4.3852
```

Solving for the variables, we get:

x = 5.0565
y = 6.3215
z = 4.3852

Therefore, the solution to the system of equations is (5.0565, 6.3215, 4.3852).

how to convert pounds to rands​

Answers

Answer:

To convert pounds to rands, you need to know the current exchange rate between the two currencies. Once you have the exchange rate, you can multiply the number of pounds by the exchange rate to get the equivalent amount in rands.

For example, if the exchange rate is 1 GBP = 20 ZAR and you want to convert 100 pounds to rands, you would multiply 100 by 20, which equals 2000 rands.

Given the below lease terms at a local car dealership, what is the total cash paid by the end of the lease when at signing the dealership required a down payment, security deposit, acquisition fee at signing and all the monthly payments paid? Length of lease =24 months MSRP of the car =$49,500 Purchase value of the car after lease =$39,500 Down payment =$3,900 Monthly payment =$775 Security deposit =$975 Acquisition fee =$500

Answers

On solving the question we have that As a result, the total amount paid equation by the lease's end is $63,475.

What is equation?

A math equation is a mechanism for connecting two statements and indicating equivalence with the equals sign (=). To explain the connection between the two sentences put on each side of a letter, a statistical method can be employed. The software and the logo are usually interchangeable. 2x - 4 equals 2, for example. An equation is a logical expression that asserts the equality of some mathematical expressions in algebra. In the equation 3x + 5 = 14, for example, the equal sign separates the numbers 3x + 5 and 14.

To compute the total cash paid at the end of the lease, we must take into account all of the lease's charges. Here's how it works:

$3,900 as a down payment

Monthly payments: $775 divided by 24 months equals $18,600.

The security deposit is $975.

The acquisition charge is $500.

After-lease automobile purchase price: $39,500

To compute the total amount paid, add all of these costs together:

$3,900 + $18,600 + $975 + $500 + $39,500 = $63,475

As a result, the total amount paid by the lease's end is $63,475.

Perimeter of the drawing is 22 inches, Perimeter of the garden is 770 inches and the Perimeter of Garden becomes 35 times the Perimeter of drawing when drawing length and breadth is multiply by 35.

What is Perimeter?

A closed route that covers, encircles, or outlines a one-dimensional length or a two-dimensional form is called a perimeter. A circle's or an ellipse's circumference is referred to as its perimeter.

Perimeter of Rectangle = 2 ( Length + Breadth)

(a) Here Length of Drawing is 7 inches and Breadth of Drawing is 4 inches.

So, Perimeter of the drawing = 2( 7 + 4 )

= 2 * 11

= 22 inches.

(b) According to question , Length and Breadth of actual garden is 35 times of the length and breadth of drawing.

Therefore, Length of Actual garden = 35 * 7 = 245 inches

and, Breadth of Actual garden = 35 * 5 = 140 inches.

So, Perimeter of the garden = 2( 245 + 140 )

= 2 * 385

= 770 inches.

(c) The perimeter of Garden becomes 35 times the perimeter of drawing when drawing length and breadth is multiply by 35.
