Use rules of transformations to answer each of the items below. Be sure to answer in complete sentences, and when necessary, inc

lude your calculations. Create your own set of coordinates for △ B L U and graph it on a coordinate plane. Label each of the triangle's vertices. Write a scenario involving the dilation of △ B L U onto its image. In the scenario, include the scale factor between the similar triangles and the coordinates for the image. Graph the image on the same coordinate plane as its pre-image. Use the distance formula or Pythagorean Theorem to prove mathematically that △ B L U is similar to its image. Include all necessary calculations.

What is the combined area of the two bases of the following cylinder
Sauron [17]
D. 226.08cm^2

Since we are finding the combined area of the two bases of the cylinder, we are adding the area of the first base with the second base. The formula for the base of a cylinder is pi x r^2, since it is a circle. Since the bases are the same, we can rewrite this as 2pi x r^2.

Since the diameter is 12cm and r = 1/2 diameter, r = 6cm.

Thus, A = 2(3.1415)(6)^2 = 226.08cm^2

Find the value of the lesser root of x 2-8x+7=0
mariarad [96]
Hi there! The answer is x = 1

{x}^{2}  - 8x + 7 = 0

(x - 7)(x - 1)
Rule AB = 0, gives A = 0 or B = 0

x - 7 = 0 \:  \: or \:  \: x - 1 = 0 \\ x = 7 \:  \:  \:  \:   \:  \:  \:  \:  \: or \:  \: x   = 1
Therefore, the smallest of both roots is x = 1.

Kelsey had $65 to spend on books. Each book cost $5.50, and there was a $7.50 fee for shipping. She let b equal the number of bo
GuDViN [60]

Answer:

Let the number of books she can purchase = b

The cost of each book is $5.5 with an extra shipping of $7.5

So, the total cost of the books she can purchase = 5.5b+7.5

Since, she had $65 to spend on the books.

The required inequality is 5.5b+7.5\leq 65.

So, according to the inequality above, we get,

The correct options are,

B. The inequality symbol is incorrect because she can spend up to and including $65.

C. The expression  5.5b+7.5 is correct because $5.50 per book is  5.5b and that is added to the shipping fee of $7.50 to determine the total purchase price.
