Answers

Answer 1

A linear equation - y = 5x -7 is a slant line with intercepts for linear equations. A vertical line is x = 2. A line that runs through the origin is y = 3/4x.

A slant line with intercepts is y = 1/2x + 3. A horizontal line is y = 9. The line x = -1 runs vertically.

A linear equation is what?

A direct condition is one that has a level of 1 as its most extreme worth. As a result, there is no variable in a linear equation with an exponent greater than 1. The graph of a linear equation will always be straight.

                  y = 5x -7 is the first line equation.

This line is not horizontal or vertical when the equation is graphed; rather, it is slant.

Additionally, this line does not traverse the origin. As a result, this equation has intercepts and slant lines.

                         x = 2 is the second line equation.

Since there is no y-intercept in this equation, it will be a vertical line that runs parallel to the y-axis.

Additionally, this line does not traverse the origin. As a result, this equation has a line that runs vertically.

                       y = 3/4x is the third equation for the line.

This line is not horizontal or vertical when the equation is graphed; rather, it is slant.

Additionally, this line actually traverses the origin. As a result, the origin of this equation is traversed by slant lines.

                             y = 1/2x + 3 is the fourth equation for a line.

This line is not horizontal or vertical when the equation is graphed; rather, it is slant.

Additionally, this line does not traverse the origin. This equation is therefore a slant line with intercepts.

                                   y = 9 is the fifth line equation.

Since there is no x-intercept in this equation, it will be a horizontal line that runs parallel to the x-axis.

Additionally, this line does not traverse the origin. As a result, there is a horizontal line in this equation.

                     x = -1 is the sixth line equation.

Since there is no y-intercept in this equation, it will be a vertical line that runs parallel to the y-axis.

Additionally, this line does not traverse the origin. As a result, this equation has a line that runs vertically.

473 determine the answer to the following questions using long division ​

Answers

There are other methods to write a division issue, such as using a / or a to denote "divided by." As a result, in the equation 473 / 2 = 1 the divisor is the quotient, the remainder is 236, and the divisor is 2.

How do you find the answer in long division?

Divide the dividend's first digit, which should be on the left, by the divisor, then write the result as the quotient on top. Write the difference below after subtracting the outcome from the digit. Bring down the dividend's next digit (if present).

Long division strategy: lengthy division techniques. The same symbols are used for long division as they are for short division: dividend (the number being divided) under the "bus stop," divisor (the number the dividend is being divided by), quotient (the solution) on top, and each place value aligned with the dividend.

Dividend Divisor = Quotient + Remainder is the formula for dividing two numbers.

Step-by-step explanation:

for the differential equation a. find all equilibrium solutions and use the first derivative test to draw the phase line for the de. b. classify each equilibrium solution as asymptotically stable , unstable or semi-stable. c. use the second derivative test for concavity and the phase line to produce a phase portrait and sketch one typical solution curves in each region determined by the equilibrium solutions.

Answers

An autonomous first order ordinary differential equation is any equation of the form: dy/dt = f(y).

1. Stable: The equilibrium solution y(t) = c is stable if all solutions with initial conditions y0 ‘near’

y = c approach c as t → ∞.

2. Unstable: The equilibrium solution y(t) = c is unstable if all solutions with initial conditions y0 ‘near’ y = c do NOT approach c as t → ∞.

3. Semi-stable: The equilibrium solution y(t) = c is semistable if initial conditions y0 on one side of c lead to solutions y(t) that approach c as t → ∞, while initial conditions y0 on the other side of c do NOT approach c.

Find the equilibrium points for the differential equation (1) and determine whether each is asymptotically stable, semistable, or unstable.

The graph of y0 as a function of y, and the phase line. (It’s important that α is positive – if it were negative, we’d have very different behavior).

We can see that there are two equilibrium solutions: y = 0, which is unstable, and y = 1, which is stable.

a represents pounds of apples and b represents pounds of bananas. guillermo and cara are finding and interpreting the solution. is either correct? explain your reasoning.

Answers

Both Guillermo's and Cara's solutions are incorrect due to the incorrect substitution of values of a variable to find the dependent one.

Guillermo's solution is incorrect because he did not substitute the value of 'b' from the first equation into the second equation. Instead, he directly added 0.49b to both sides and solved for a, which gives an incorrect result.

Cara's solution is also incorrect because she did not substitute the value of 'a' from the first equation into the second equation. Instead, she used the equation a + b = 7 to solve for the value of b, which gave her an incorrect result.

We can find the correct solution as follows -

The system of equations is,

⇒ a + b = 7   .. (i)

And 1.29a + 0.49b = 6.63 .. (ii)

Now, we will solve the system of equations as follows -

⇒ a + b = 7  

⇒ a = 7 - b .. (i)

And, ⇒ 1.29a + 0.49b = 6.63 .. (ii)

Substitute the value of a from (i) in (ii), we get;

⇒ 1.29a + 0.49b = 6.63

⇒ 1.29(7 - b) + 0.49b = 6.63

⇒ 9.03 - 1.29b + 0.49b = 6.63

⇒ - 0.8b = 6.63 - 9.03

⇒ - 0.8b = - 2.4

⇒ 0.8b = 2.4

⇒ b = 2.4 / 0.8

⇒ b = 3

And, From (i);

⇒ a = 7 - b .. (i)

⇒ a = 7 - 3

⇒ a = 4

Hence, 4 pounds of apples and 3 pounds of bananas were bought.

Thus, both of their solutions are incorrect.

FIND THE ERROR In the system a + b = 7 and 1.29a + 0.49b = 6.63, a represents pounds of apples and b represents pounds of bananas a person bought. Guillermo and Cara are finding and interpreting the solution. Is either correct? Explain your reasoning.

a. Guillermo: 1.29a + 0.49b = 6.63 ⇒ 1.29a +0.49(a + 7) = 6.63 ⇒ 1.29a + 0.49a + 3.43 = 6.63 ⇒ 1.78a = 3.2 ⇒ a = 1.8

a + b = 7, so b = 5.2. The solution (1.8, 5.2) means that 1.8 pounds of apples and 5.2 pounds of bananas were bought.

b. Cara: 1.29a + 0.49b = 6.63 ⇒ 1.29(7-b) + 0.49b = 6.63 ⇒ 9.03- 1.29b + 0.49b = 6.63 ⇒ -0.8b = -2.4 ⇒ b=3

Line F passes through points (2, 8) and (9, 3). Line g passes through points (1, 8) and (10, 1). Are line f and line g parallel or perpendicular? Pls help I’m getting frustrated

Answers

The linear functions f(x) and g(x) are neither parallel nor perpendicular.

How to obtain if the lines are parallel or perpendicular?

To obtain whether they are parallel of perpendicular, first we must obtain the slope of each line.

Given two points, the slope of a line is calculated as the change in y divided by the change in x.

Hence, the slope for each line is obtained as follows:

Line F: m = (3 - 8)/(9 - 2) = -5/7.Line G: m = (1 - 8)/(10 - 1) = -7/9.

They would be:

Parallel if they have the same slope.Perpendicular if the product of the slopes was of -1.

Hence they are neither.

The altitudes, the medians, and the angle-bisectors are distinct for the congruent sides but coincident for the base. Hence, 7 lines.

Now, According to the question:

Altitude. A line segment joining a vertex of a triangle with the mid-point of the opposite side. An altitude is a perpendicular line segment drawn from a vertex of a triangle to the opposite side. It divides the opposite sides into two equal parts.

A Median of a triangle is a straight line segment which is drawn from the vertex of a triangle to the middle point of the opposite side. It splits the opposite side of the triangle into two equal line segments. That means we know that it's a median if we have got those equal line segments.

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The coordinate points for cups of flour, x and loaves of bread y is given in the table.

The slope-intercept form of an equation is - y = mx + b

To find the slope m use the formula -

(y2 - y1)/(x2 - x1)

Substituting the values in the equation -

(3 - 2)/(9 - 6)

1/3

So, the slope point is obtained as m = 1/3.

The equation becomes - y =1/3 x + b

To find the value of b substitute the values of x and y in the equation -

2 = 1/3(6) + b

2 = 2 + b

b = 2 - 2

b = 0

So, the value for b is 0.

Now, the equation becomes -

y = 1/3x + 0

y = 1/3x

The graph is plotted for the equation.

Answers

ΔABC and ΔDEF are not similar because corresponding angles are not equal.

Now, According to the question:

In triangle ABC :

The measure of angle A is 35º and

The measure of angle B is 20°.

In triangle DEF:

The measure of angle D is 35º and

The measure of angle F is 125

We know that :

Sum of interior angles of triangle is 180°

Now, In ΔABC:

∠A + ∠B + ∠C = 180°

35 +  20 + ∠C = 180°

55° +  ∠C = 180°

∠C = 180° - 55°

∠C = 125°

Now,  In ΔDEF:

∠D + ∠E + ∠F = 180°

35 + ∠E + 125 = 180°

160  + ∠E = 180°

∠E = 180° - 160°

∠E = 20°

So, ∠C ≠ ∠E  as ∠C = 125° and ∠E =20°

Making  triangular  and  Rectanglar garden with woods of different lengths

Part A: Wendell cannot make a triangular garden using pieces A, B, and F because the sum of the lengths of the two shorter sides of a triangle (in this case, pieces A, B, and F) must be greater than the length of the longest side (in this case, piece F, which is 2 feet long) in order for the triangle to be a valid one. Since the sum of the lengths of pieces A and B is 12 feet, which is greater than the length of piece F, it is not possible to make a triangular garden using these pieces.

Part B: Wendell cannot make a triangular garden using pieces D, E, and F because the sum of the lengths of the two shorter sides of a triangle (in this case, pieces D, E, and F) must be greater than the length of the longest side (in this case, piece D, which is 8 feet long) in order for the triangle to be a valid one. Since the sum of the lengths of pieces E and F is 5 feet, which is less than the length of piece D, it is not possible to make a triangular garden using these pieces.

Part C: Wendell can make a rectangular garden with the pieces of wood he has by using pieces A and C or pieces B and D. He cannot use pieces E and F because they are not long enough to make up one of the sides of a rectangle.

Part  D: Wendell can not create two triangular gardens using all six pieces of wood as the sum of the lengths of the two shorter sides of a triangle must be greater than the length of the longest side, and he only have 3 pieces with length greater than 3 feet which is required to create one triangle.

Wendell can create two rectangular gardens using all six pieces of wood by using pieces A and C, and pieces B and D.

Part E: The area that Jordan can walk around is equal to the area of a circle with a radius of 6 feet (since the chain is 12 feet long).

The formula to calculate the area of a circle is πr^2

where π is approximately 3.14 and

r is the radius of the circle,

so the area that Jordan has to walk around is approximately

of five letters (a, b, c, d, and e), three letters are to be selected at random. how many possible selections are there?

Answers

Three letters will be selected from five letters. The number of possible selections is 10.

A combination is a method of picking elements from a collection where the order of selection is irrelevant. Assume we have three numbers P, Q, and R. The number of ways we can choose two numbers from each set is determined by combination.

Suppose we want to pick k elements from a set of n elements, then the number ways it can be chosen is:

C(n,k) = n! / k! (n-k)!

Where n! is n factorial.

In this case, there are 5 letters and we want to select three letters. Hence, k = 3, and n = 5.

C(5,3) = 5! / 3! (5-3)!

C(5,3) = 5! / (3! 2!) = 10

given four sets: a, b, c and d. each set has 15. the pair-wise intersections have 4 elements. the three-way intersections have 3 elements. there are 2 elements in the intersection of all sets. how many elements are there in total?

Answers

There are 46 elements in total for 4 sets A, B, C, and D.

Consider 4 sets A, B, C, and D.

Each set has 15 elements.

The pair-wise intersection has 4 elements.

The three-way intersection has 3 elements.

There are 2 elements in the intersection of all sets.

So,

P(A) = P(B) = P(C) = P(D) = 15

P(A ∩ B) = P(A ∩ C) = P(A ∩ D) = P(B ∩ C) = P(B ∩ D) = P(C ∩ D) = 4

P(A ∩ B ∩ C) = P(A ∩ B ∩ D) = P(A ∩ C ∩ D) = P(B ∩ C ∩ D) = 3

P(A ∩ B ∩ C ∩ D) = 2

The total number of elements are:

P (A U B U C U D) = P(A) + P(B) + P(C) + P(D) - P(A ∩ B) - P(A ∩ C) - P(A ∩ D)- P(B ∩ C) - P(B ∩ D) - P(C ∩ D) + P(A ∩ B ∩ C) + P(A ∩ B ∩ D) + P(A ∩ C ∩ D) + P(B ∩ C ∩ D) - P(A ∩ B ∩ C ∩ D).

P (A U B U C U D) = 15 + 15 + 15 + 15 - 4 - 4 - 4 - 4 - 4 - 4 + 3 + 3 + 3 + 3 - 2

= 60 - 24 + 12 - 2

Step-by-step explanation:

8. At a fund raising event, a booth was set up to sell handmade cards and photo
frames. On the first day, 3 cards and 9 photo frames were sold for a total of $75.
The next day, 8 cards and 5 photo frames were sold for a total of $67.
Find the selling price of a card and the selling price of a photo frame.

Answers

We can start solving this problem by using a system of equations. Let x be the selling price of a card and y be the selling price of a photo frame.

From the information given, we know that on the first day:

3x + 9y = 75 (1)

And on the second day:

8x + 5y = 67 (2)

Now we have two equations with two variables. To find the value of x and y, we can use either substitution or elimination method.

One possible way to solve for x and y is to use substitution method:

Solve equation (1) for x in terms of y:

x = (75 - 9y) / 3

Substitute this expression into equation (2) to eliminate x:

8((75 - 9y) / 3) + 5y = 67

Solving this equation for y:

y = 3

Now we can substitute this value of y back into equation (1) or (2) to find the value of x:

3x + 9(3) = 75

3x = 48

x = 16

So the selling price of a card is $16 and the selling price of a photo frame is $3.

Answer:

Photo frame = $7

Card = $4

Step-by-step explanation:

Define the variables:

Let c = the selling price of a handmade card (in dollars).Let p = the selling price of a handmade photo frame (in dollars).

Given information:

On the first day, 3 cards and 9 photo frames were sold for a total of $75.On the next day, 8 cards and 5 photo frames were sold for a total of $67.

Create a system of linear equations using the given information and defined variables:

[tex]\begin{cases}3c + 9p = 75\\ 8c + 5p = 67\end{cases}[/tex]

Rearrange the first equation to isolate c:

[tex]\implies 3c+9p=75[/tex]

[tex]\implies 3(c+3p)=75[/tex]

[tex]\implies \dfrac{3(c+3p)}{3}=\dfrac{75}{3}[/tex]

[tex]\implies c+3p=25[/tex]

[tex]\implies c+3p-3p=25-3p[/tex]

[tex]\implies c=25-3p[/tex]

Substitute the expression for c into the second equation and solve for p:

[tex]\implies 8c+5p=67[/tex]

[tex]\implies 8(25-3p)+5p=67[/tex]

[tex]\implies 200-24p+5p=67[/tex]

[tex]\implies 200-19p=67[/tex]

[tex]\implies 200-19p-200=67-200[/tex]

[tex]\implies -19p=-133[/tex]

[tex]\implies \dfrac{-19p}{-19}=\dfrac{-133}{-19}[/tex]

[tex]\implies p=7[/tex]

Therefore, the selling price of a handmade photo frame was $7.

Substitute the found value of p into the expression for c and solve for c:

[tex]\implies c=25-3p[/tex]

[tex]\implies c=25-3(7)[/tex]

[tex]\implies c=25-21[/tex]

[tex]\implies c=4[/tex]

Therefore, the selling price of a handmade card was $4.
