The answer is C.

A dilation is a transformation whose preimage and image are similar.

Since the apostrophe (') shows that these coordinate points have already been altered and the scale factor is greater than 1, we know the dilation is an enlargement. Therefore, we must divide each number by the scale factor, 7 to get the answer C.

Represent the following expressions as a power of the number a (a≠0): c ((a2)−2)5÷(a4a)3
s2008m [1.1K]

Answer:

1/a²⁷

Step-by-step explanation:

Given: $ \frac{((a^2)^{-2})^5}{a^4.a^3} $

We know that when the bases are same the powers can be added. i.,e.,

                                           (xᵃ)ᵇ = x ⁽ᵃ ⁺ ᵇ⁾

⇒ $ \frac{((a^2)^{-2})^5}{a^4.a^3} \implies \frac{(a^2)^{-10}}{a^7} $

$  \implies \frac{a^{-20}}{a^7} = a^{-20 - 7} = a^{-27} $

Also, $ \frac{x^a}{x^b} = x^{a - b} $

This is nothing but, $ \frac{1}{a^{27}} $.

Note that $ a $ cannot be zero here. The condition is provided in the question as well.

What is the exact area of a circle with a diameter of 18 feet?
Kitty [74]
The formula for the area of a circle is 

\pi  r^{2}

We know the diameter, and the radius is half of the diameter.  So the radius is 9.  Now we plug that into the formula.

\pi  9^{2} =81 \pi

So the answer is B, 81 pi square feet
