Write the equation of the line that passes through the points (3, -4) and (7, 6). Put
your answer in fully simplified point-slope form, unless it is a vertical or horizontal
line.

Answers

Answer:

Step-by-step explanation:

To write the equation of the line that passes through the points (3, -4) and (7, 6), we can follow these steps:

Step 1: Find the slope of the line

The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:

slope = (y2 - y1) / (x2 - x1)

Plugging in the given values, we get:

slope = (6 - (-4)) / (7 - 3)

slope = 10 / 4

slope = 5 / 2

Step 2: Use point-slope form to write the equation of the line

Point-slope form of a line with slope m passing through a point (x1, y1) is given by:

y - y1 = m(x - x1)

We can use either of the given points to write the equation. Let's use (3, -4):

y - (-4) = (5/2)(x - 3)

Simplifying this equation, we get:

y + 4 = (5/2)x - (15/2)

Subtracting 4 from both sides, we get:

y = (5/2)x - (23/2)

This is the equation of the line in point-slope form.

Step 3: Simplify the equation if it is not in point-slope form

The equation we obtained in step 2 is already in point-slope form, so we do not need to simplify it any further.

Note: If the line was horizontal (i.e., it had zero slope), then its equation would be y = constant, where the constant is the y-coordinate of any point on the line. If the line was vertical (i.e., its slope was undefined), then its equation would be x = constant, where the constant is the x-coordinate of any point on the line.

After simplifying a mixed number is 5 1/16

A mixed number is a combination of a whole number and a fraction.

It is typically written in the form "a b/c", where "a" is the whole number, "b" is the numerator of the fraction, and "c" is the denominator of the fraction.

For example, 3 1/2 is a mixed number, where 3 is the whole number, 1 is the numerator of the fraction, and 2 is the denominator of the fraction. This mixed number can also be expressed as an improper fraction as follows:

3 1/2 = (3 × 2 + 1) / 2 = 7/2.

Conversely, an improper fraction can be converted to a mixed number by dividing the numerator by the denominator to obtain the whole number and expressing the remainder as a fraction.

To multiply 2 1/4, follow these steps:
1. Convert the mixed number to an improper fraction: 2 1/4 = (2 × 4 + 1) / 4 = 9/4
2. Multiply the improper fraction by itself: (9/4) × (9/4)
3. Multiply the numerators: 9 × 9 = 81
4. Multiply the denominators: 4 × 4 = 16
5. Write the result as a fraction: 81/16
6. Simplify the fraction by converting it to a mixed number:

81 ÷ 16 = 5, with a remainder of 1.

So, 81/16 = 5 1/16.

Find the equation of a straight line with the following gradients and points .1. 2,(7,2) .2. -2(6,-3)

Answers

Answer:

The gradient is given as m=1, and the point (7,2) lies on the line. Thus:

y - y1 = m(x - x1)

y - 2 = 1(x - 7)

y - 2 = x - 7

y = x - 5

So the equation of the line is y = x - 5.

Again, using the point-slope form of a straight line:

The gradient is given as m=-2, and the point (6,-3) lies on the line. Thus:

y - y1 = m(x - x1)

y - (-3) = -2(x - 6)

y + 3 = -2x + 12

y = -2x + 9

So the equation of the line is y = -2x + 9.

What is the equation of the line in slope-intercept form that goes thru the point (8, -2) and has a slope of 1/4?

Answers

The equation of the line in slope-intercept form that goes through the point (8, -2) and has a slope of 1/4 is y = 1/4x - 4.

What is slope-intercept form?

In slope-intercept form, the equation of a line is expressed as y = mx + b, where m denotes the slope of the line and b the y-intercept, or the location at where the line intersects the y-axis. In this form, the slope m denotes the line's steepness or the rate at which y changes in relation to x. A positive slope causes the line to go upward from left to right, whereas a negative slope causes the line to move downward from left to right. The value of y when x is 0, or the line's origin, is represented by the y-intercept, or b.

Given that, point (8, -2) and a slope of 1/4.

The slope-intercept form is given as:

y - y1 = m(x - x1)

Substituting the values:

y - (-2) = 1/4(x - 8)

y + 2 = 1/4x - 2

y = 1/4x - 4

Hence, the equation of the line in slope-intercept form that goes through the point (8, -2) and has a slope of 1/4 is y = 1/4x - 4.

The slope of the line is -50 and it means that the amount of money in the account is decreasing at a rate of $50 every week.

What is meant by the slope of the line?

A line's slope is defined as the ratio of the change in the y coordinates to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.

As a result, m = change in y/change in x is the formula for the change in the y-coordinate with respect to the change in the x-coordinate.

where "m" represents a line's slope.

A line's slope provides information on the steepness and direction of the line. By calculating the difference between the coordinates of the two points, (x1,y1) and (x2,y2), it is simple to calculate the slope of a straight line between them.

The complete question is given below.

Answers

Total interest is $149,528.31
Step-by-step explanation:
In the first place,Tom already has 25%*$300,000=$75,000
This implies that the mortgage amount=$300,000-$75,000=$225,000
In order to ascertain the total interest Tom would pay it would necessary to know the total amount Tom would have to pay back in respect of the mortgage since the total interest is the difference between total amount repayable less the present worth of the mortgage of $225,000
FV=PV*(1+r)^n
FV is the future worth of the mortgage i.e total amount repayable
PV is the present worth of $225,000
r is the rate of interest of 2% yearly,but 0.17% monthly(2%/12)
n is the number of month it would take Tom to repay the mortgage i.e 25 years multiplied by 12 300 months
FV=$225,000*(1+0.17%)^300=$ 374,528.31
Total interest=$ 374,528.31-$225,000=$149,528.31

Avani is trying to find the height of a radio antenna on the roof of a local building. She stands at a horizontal distance of 21 meters from the building. The angle of elevation from her eyes to the roof ((point AA)) is 38^{\circ} ∘ , and the angle of elevation from her eyes to the top of the antenna ((point BB)) is 46^{\circ} ∘ . If her eyes are 1.66 meters from the ground, find the height of the antenna ((the distance from point AA to point BB)). Round your answer to the nearest tenth of a meter if necessary.

Answers

Answer:

Let's call the height of the antenna "h".

First, we can use the angle of elevation of 38^{\circ} ∘ to find the height of point A above the ground.

tan(38^{\circ}) = \frac{h}{21}

h = 21 \cdot tan(38^{\circ})

h \approx 15.6

So point A is approximately 15.6 meters above the ground.

Next, we can use the angle of elevation of 46^{\circ} ∘ to find the height of point B above the ground.

tan(46^{\circ}) = \frac{h}{d}

h = d \cdot tan(46^{\circ})

We can find the value of "d" using the Pythagorean theorem.

d^2 = 21^2 + 15.6^2

d \approx 25.7

So the distance from point A to point B is approximately 25.7 meters.

Finally, we can use the height of point A and the distance from point A to point B to find the height of point B (the height of the antenna).

h = d \cdot tan(46^{\circ})

h \approx 25.7 \cdot tan(46^{\circ})

h \approx 23.2

Therefore, the height of the antenna is approximately 23.2 meters.

Step-by-step explanation:

the scenario creates 2 right-angled triangles.

both have the same first leg : the horizontal distance from Avani's eyes to the building (21 m).

and both have a right angle (90°) at the point, where the horizontal distance meets the building.

the difference is now the second leg : the height of the building (starting at 1.66 m above ground), and the height of the building plus the height of the antenna (again starting at 1.66 m above ground).

another difference is the length of the line of sight (from Avani to AA, and from Avani to BB).

driving these differences is the difference in the angle at Avani (38° vs. 46°).

now, remember the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

a, b, c are the sides of the triangle, A, B, C are the corresponding opposite angles of the triangle.

and remember : the sum of all angles in a triangle is always 180°.

what is the plan ?

we need to calculate the second leg of the larger triangle, and then the second leg of the smaller triangle and subtract that from the second leg of the larger triangle.

in other words :

(building + antenna) - building = antenna

so, we start with the larger triangle (up to BB).

the angle at Avani is 46°.

the angle at the building is 90°.

the angle at BB is then

180 - 90 - 46 = 44°.

21/sin(44) = (building + antenna)/sin(46)

(building + antenna) = 21×sin(46)/sin(44) =

= 21.74613659... m

now, for the smaller triangle (up to AA).

the angle at Avani is 38°.

the angle at the building is 90°.

the angle at AA is then

180 - 90 - 38 = 52°.

21/sin(52) = building/sin(38)

building = 21×sin(38)/sin(52) = 16.40699816... m

the height of the antenna is then again

(building + antenna) - building = 5.339138433... m

≈ 5.3 m

A coordinate system can be used to precisely find points or additional mathematical objects on such a space, including Euclidean space, by using one or more variables or coordinates. To find a point or item on a double plane, one uses coordinates, which are pairs of numbers. Two numbers called the y and x matrices are used to describe a point's location on a two-dimensional plane. a set of numbers used to identify specific locations.

=>  x=6 is 6 - (-3) = 9,

which is also T's separation from the line x=6.

The y-coordinate of T is the same as the y-coordinate of t because the line of reflection is the perpendicular bisector of the section joining t and T, which is:

Determine whether y varies directly with x if so, solve for the constant of variation k. 3y= -7x-18

Answers

This shows that any increase in x by a certain factor results in an increase in y by the same factor, confirming that y varies directly with x.

What is Linear equation ?

Linear equation can be defined as equation in which highest degree is one.

To determine if y varies directly with x, we need to check if there is a constant ratio between y and x. In other words, if we increase x by a certain factor, does y also increase by the same factor?

The equation 3y = -7x - 18 can be rewritten as y = (-7/3)x - 6. This is in the form of y = kx + b, where k is the constant of variation and represents the ratio between y and x.

Since the equation is in this form, we can say that y varies directly with x, and the constant of variation is k = -7/3.

To verify that y varies directly with x, we can check that any increase in x by a certain factor results in an increase in y by the same factor, as given by the constant of variation. For example, if we increase x by 3, then y will increase by (-7/3)(3) = -7. If we increase x by 6, then y will increase by (-7/3)(6) = -14.

Therefore, This shows that any increase in x by a certain factor results in an increase in y by the same factor, confirming that y varies directly with x.

Solve x2 – 18x + 81 = 4 by completing the square. Select any solutions that apply. A. x = –11 B. x = –7 C. x = 7 D. x = 11

Answers

The solutions to the equation x² - 18x + 81 = 4 by completing the square are x = 9 + 2i and x = 9 - 2i.None of the answer choices A, B, C, or D are correct.

What is an equation?

An equation is a mathematical statement that shows the equality between two expressions, often containing variables and mathematical operations.

To solve the equation x² - 18x + 81 = 4 by completing the square, we can follow these steps:

x² - 18x + 77 = 0

Divide both sides by the coefficient of x² to make the coefficient 1:

x² - 18x + (81/1) = -77/1

x² - 18x + 81 = -77

Add the square of half the coefficient of x to both sides of the equation:

x² - 18x + (9)² = -77 + (9)²

x² - 18x + 81 = -4

(x - 9)² = -4

x - 9 = ±√(-4)

x - 9 = ±2i (where i is the imaginary unit)

x = 9 ±2i

A toy company is building dollhouse furniture. A rectangle door of a dollhouse has a height of 7 centimeters and a width of 3 centimeters. What is the perimeter of the door on a scale drawing that uses the scale 3.5?

Answers

Answer: To find the perimeter of the door on a scale drawing, we need to first determine the dimensions of the door on the scale drawing.

If the actual height of the door is 7 centimeters, then the height on the scale drawing will be:

7 cm ÷ 3.5 = 2 cm

Similarly, if the actual width of the door is 3 centimeters, then the width on the scale drawing will be:

3 cm ÷ 3.5 = 0.857 cm

Now we can use these dimensions to find the perimeter on the scale drawing:

Perimeter = 2 × (height + width) = 2 × (2 cm + 0.857 cm) = 2 × 2.857 cm = 5.714 cm

Therefore, the perimeter of the door on the scale drawing is 5.714 centimeters.

5. A rock is thrown directly upward with an initial velocity of 79 feet per second from a cliff 50 feet above a beach. The height of the rock above the beach (h) after t seconds is given by the equation h = -16t² + 79t + 50. The graph below shows the rock's height as a function of time.

Answers

The rock will be at a height of 125 feet after 0.49 and 4.76 seconds.

Finding the time:

In the given problem we have a function h(t) that represents the height of the rock that is from the ground of the beach where the variable represents the time travel by the rock.

Assume t as required time equates the given function to the given height and solve for the value of 't'.

Here we have

A rock is thrown directly upward with an initial velocity of 79 feet per second from a cliff 50 feet above a beach.

The height of the rock above the beach (h) after t seconds is given by the equation h(t) = -16t² + 79t + 50.  

Let after t seconds the height will be 125 feet

=> h(t) = 125  

=>  -16t² + 79t + 50 = 125

=> -16t² + 79t - 75 = 0

   

To solve this quadratic equation, we can use the quadratic formula:

=> x = [-b ± √(b² - 4ac)]/ 2a

Here a = -16, b = 79, and c = -75.  

t = [-79 ± √(79² - 4(-16)(-75))] / 2(-16)

t = (-79 ± √(6241 - 4800)) / -32

t = (-79 ± √1441) / -32

So, the two solutions are:

t = (-79 + √1441) / -32 and   t = (-79 - √1441) / -32

t ≈ 0.497 or t ≈ 4.763

Therefore,

The rock will be at a height of 125 feet after 0.49 and 4.76 seconds

The demand for a product is given by p+5q= 380 or, q = (380-p)/5 and the supply for this product is given by p-3q = 172 or, q = (p-172)/3 The price at which the quantity demande

Answers

Answer:

The equilibrium price is $250.

The equilibrium quantity is 26 units.

Step-by-step explanation:

To find the equilibrium price, we need to find the price at which the quantity demanded equals the quantity supplied. This occurs when q (quantity demanded) equals q (quantity supplied).

So, we can set the two equations for q equal to each other:

(380-p)/5 = (p-172)/3

To solve for p, we can cross-multiply and simplify:

3(380-p) = 5(p-172)

1140 - 3p = 5p - 860

1140 + 860 = 8p

2000 = 8p

p = 250

Therefore, the equilibrium price is $250. We can plug this value back into either equation for q to find the equilibrium quantity.

Using q = (380-p)/5, we get:

q = (380-250)/5 = 26

So the equilibrium quantity is 26 units.

Solve for s. 0.5s + 1=7+4.5s=​

Answers

Answer:

s = -1.5

Step-by-step explanation:

0.5s + 1 = 7 + 4.5s

So we can combine like terms

Put 0.5s to other side

Put 7 to other side

Then you get the equation:

1 - 7 = 4.5s - 0.5s

So we simplify:

-6 = 4s

That means

s = -6/4

s = -1.5
