ABC has coordinates of A(–5, –7), B(6, –3), and C(2, 7). Find the coordinates of its image after a dilation centered at the origin with a scale factor of 2.

Answers

Answer 1

When a figure is dilated about the origin, every coordinate is multiplied by the scale factor.

A' = 2A = (-10, -14)
B' = 2B = (12, -6)
C' = 2C = (4, 14)

Answer 2

Final answer:

The coordinates of the image after dilation with a scale factor of 2 are A'(-10, -14), B'(12, -6), C'(4, 14).

Explanation:

Your question involves geometry and specifically, dilation transformations. A dilation is a transformation that moves each point along the ray from the center of dilation to the point. The number given as the scale factor tells you how much to move. In this case, we are asked to dilate the given points with a scale factor of 2 centered at the origin (0,0).

So, each coordinate of the original triangle should be multiplied by 2. Let's find each coordinate after dilation:

A: -5*2, -7*2 = A'(-10, -14)B: 6*2, -3*2 = B'(12, -6)C: 2*2, 7*2 = C'(4, 14)

So, the coordinates of the image after a dilation with a scale factor of 2 are A'(-10, -14), B'(12, -6), and C'(4, 14).

The radius of a cone can be found using the formula r=3⁢Vπ⁢h , where V stands for the volume of the cone and h stands for the height. If r=3 , h=8 , and π is 3.14, find the volume (V). Round the answer to the nearest hundredths place.

Answers

The right expression for r is give as follows:

r = Sqrt [(3V)/(πh)]

Making the V the subject of the formula
r^2 = (3V)/(πh)
V = πr^2h/3

Substituting,
V= 3.14*3^2*8/3 = 75.36 sq. units

Using the formula for the radius of a cone and the given values of r = 3, h = 8, and [tex]\pi[/tex] = 3.14, the volume of the cone is calculated to be approximately 25.12 [tex]cm^3[/tex].

To find the volume V of a cone, we need to solve for V in the given formula [tex]$ r = \frac{3V}{\pi h} $. With $ r = 3 $,[/tex] h = 8, and [tex]\pi = 3.14[/tex], let's proceed as follows:

Rearrange the Formula

1. Given that [tex]$ r = \frac{3V}{\pi h} $[/tex], isolate V to get:

[tex]\[ V = \frac{r \cdot \pi \cdot h}{3} \][/tex]

2. Using r=3, h=8, and [tex]$ \pi = 3.14 $[/tex]:

[tex]\[ V = \frac{3 \cdot 3.14 \cdot 8}{3} \][/tex]

3. Simplify and solve:

[tex]\[ V = 3.14 \cdot 8 \approx 25.12 \][/tex]

Rounding to the nearest hundredths place, the value for the volume V is approximately 25.12 cubic units.

A batch of cookies requires 3/8 cup of butter. Butter can be purchased in boxes, each containing 4 sticks, with 1 stick equivalent to 1/2 cup of butter. If Monica is to bake 15 batches of cookies, which of the following is the best estimate for the total number of boxes of butter she needs to buy?

Answers

Firstly, we need to find how many cups of butter is needed to bake [tex]15[/tex] batches. We will need [tex]15 \cdot \frac{3}{8} = \frac{45}{8}[/tex] cups of butter. This is [tex]5.625[/tex] cups. Since we can only buy butter in boxes with 2 cups of butter in it, we will have to buy 3. This will give us 6 cups of butter, which will be enough.

True or False? The shortest distance from the center of the circumscribed circle to the sides of the inscribed triangle is the circle's radius

Answers

Answer:

false

Step-by-step explanation:

The statement that the shortest distance from the center of the circumscribed circle to the side of the inscribed triangle is the circle's radius is false.

How to find the radius of the circumscribed circle around a triangle?

The intersection of the perpendicular bisectors of any two sides(or all three sides if you want) is the center of the circumscribed circle for that triangle.

The length of that intersection point from any of the vertices of the triangle is the radius of the circumscribed circle of that triangle.

When a triangle is placed in a circle such that the side of the circle touch the circumference of the circle, then the circle is a circumscribed circle.

The line drawn from the center of the circle to the side of the triangle is the shortest possible line.

However, it is certain that this line is the radius.

This is so because the side of the triangle lie on the circumference of the circle

Hence, the statement that the shortest distance from the center of the circle is false.

Q # 17 , Find the slope

Answers

In order to find the slope we need to find two points on the line.

From the above graph we can see that the points (-4,-1) and (0, -3) lie on the line. So using these two points we can find the slope.

[tex]Slope=m= \frac{-3-(-1)}{0-(-4)} \\ \\ m= \frac{-3+1}{0+4} \\ \\ m= \frac{-2}{4} \\ \\ m= \frac{-1}{2} [/tex]

So, first option is the correct answer

The slope is given by:
m = (y2-y1) / (x2-x1)
Substituting values we have:
m = (- 4 - (- 3)) / (2-0)
Rewriting we have:
m = (- 4 + 3) / (2-0)
m = (- 1) / (2)
m = -1 / 2
Answer:
The slope is given by:
m = -1 / 2

which is an example x-intercept of the graph of the function y=tan(x-(5pi/6))

Answers

Answer: x = 5π/6

Explanation:

1) Given function:

[tex]y=tan(x- \frac{5 \pi }{6} )[/tex]

2) x-intercept are the roots of the function, i.e. the solution to y = 0

3) to find when y = 0, you can either solve the equation or look at the graph.

4) Solving the equation you get:

y = 0 ⇒ tan(x - 5π/6) = 0 ⇒ x - 5π/6 = arctan(0)

arctan(0) is the angle whose tangent is zero,so this is 0

⇒ x - 5π/6 = 0 ⇒ x = 5π/6.

Then, one example of an x-intercept is x = 5π/6, which means that when x = 5π/6, the value of the function is 0.

Since, the tangent function is a periodic function, there are infinite x-intecepts, that is why the questions asks for one example and not all the values.

You can verify by replacing the value x = 5π/6 in the given function:

y = tan (5π/6 - 5π/6) = tan(0) = 0.

Aisha wants to make two quilts, each with the same area. The first quilt will be square with sides s feet long. The second quilt will be a rectangle with a width that is half the length of a side of the square quilt and a length that is 6 feet longer than a side length of the square quilt. Which quadratic equation can be used to find s, the side length of the square quilt?
s^2 =(1/2s) (s + 6)
s^2 = (s)(s + 6)
s^2 =(1/2s) (6s)
s^2 = (s)(6s)

Answers

Sides of a square shape = S

Then, Area (A) = S^2

Width of rectangular shape = S/2
Length of rectangular shape = S+6

Then, Area (A) = (1/2S)(S+6)

The two area are equal. Therefore,
S^2 = (1/2S)(S+6)

The first option is the correct quadratic equation to solve for S.

Answer:

Option 1 - [tex]s^2=(\frac{1}{2}s)(s+6)[/tex]

Step-by-step explanation:

Given : Aisha wants to make two quilts, each with the same area. The first quilt will be square with sides s feet long. The second quilt will be a rectangle with a width that is half the length of a side of the square quilt and a length that is 6 feet longer than a side length of the square quilt.

To find : Which quadratic equation can be used to find s, the side length of the square quilt?

Solution :

The first quilt will be square,

Let the side of square be s

The area of the square is [tex]A=s\times s[/tex]

The second quilt will be a rectangle,

A width that is half the length of a side of the square quilt and a length that is 6 feet longer than a side length of the square quilt.

Width of the rectangle = [tex]\frac{1}{2}s[/tex]

Length of the rectangle = s+6

Area of the rectangle is [tex]A=(\frac{1}{2}s) \times (s+6)[/tex]

According to question,

Area of square and rectangle are equal,

So, [tex]s\times s=(\frac{1}{2}s) \times (s+6)[/tex]

[tex]s^2=(\frac{1}{2}s)(s+6)[/tex]

Therefore, Option 1 is correct.

The required equation is [tex]s^2=(\frac{1}{2}s)(s+6)[/tex]

Answer: Width = 8 inches

Final answer:

To find the width of Jyzette's folder with a perimeter of 38 inches and a length of 11 inches, we use the perimeter formula for a rectangle, solve for width, and find that the width of the folder is 8 inches.

Explanation:

Finding the Width of a Folder

To determine the width of Jyzette's folder, we use the formula for the perimeter of a rectangle, which is P = 2l + 2w, where P is perimeter, l is length, and w is width. Given that the perimeter is 38 inches and the length is 11 inches, we can set up the equation:

38 = 2(11) + 2w

Simplifying the equation: 38 = 22 + 2w. We then subtract 22 from both sides, resulting in 16 = 2w, and finally, dividing both sides by 2 gives us w = 8. Therefore, the width of the folder is 8 inches.
