what is true about every rotation? the image and pre-image are congruent. the image is larger than the pre-image. the image over

Rudiy27

I think the correct answer from the choices listed above is the first option. The statement that is true for every rotation would be that the image and pre-image are congruent. A<span>ll the rest deals with changing the rotated shape not a constant. Hope this helps.</span>

The drawing plan for an art studio shows a rectangle that is 15.2 inches by 8 inches. The scale in the plan is 4 in.: 5 ft. Find

Kamila [148]

Answer:

Length: 19 feet

Width: 10 feet

Area: 190 feet $x^{2}$

Step-by-step explanation:

This is a question about ratio.

Length: let $x$ be the actual length.

$15.2 : x = 4 : 60$

$x = 19$

Width: let $y$ be the actual width.

$8 : y = 4 : 60$

$y = 10$

Area: A = xy

$19 * 10 = 190$

Which of the following graphs of exponential functions corresponds to a geometric sequence with a first term of 4 and a ratio of

ser-zykov [4K]

Answer: graph E.

A geometric sequence can be written as:

$a_{n} = a_{1} \cdot r^{(n - 1)}$

where:

a₁ = first term = 4

r = ratio = 0.5

Substituting the numbers, we have:

$a_{n} = 4 \cdot (\frac{1}{2})^{n-1}$

or else

$f(x) = 4 \cdot (\frac{1}{2})^{x - 1}$

This is an exponential function with base less than 1. Therefore, we can exclude graph C (which depicts a linear function), and graphs A and D (which depict an exponential function with base greater than 1).

In order to choose between graph B and E, let's evaluate the function in two different points:

$f(1) = 4 \cdot (\frac{1}{2})^{1 - 1} = 4$
