Yes they are congruent.
Exactly equal in size and shape. Congruent sides or segments have the exact same length. Congruent angles have the exact same measure. For any set of congruent geometric figures, corresponding sides, angles, faces, etc. are congruent.

A. (7, -2), (4, -1), (3, 0), (4, 1), (7,2)

Kisachek [45]

Since someone answered wrongly I'll try to give the correct answer without the given xs. It won't matter. We're looking for a set of points which satisfy

y = f(x) = x² + 3

A. f(7)=7² + 3 = 52, not -2, so not A.

B. f(-2)=(-2)² + 3 = 7, not 1, so not B

C. f(-2)=7, that's good so far.

f(-2)=(-1)²+3=1+3=4, good

f(0) = 0²+3 = 3, good

f(1)=1²+3 = 4, good

f(2) = 2²+3 = 7, good

Answer: C

We'll rule out D. f(1)=1²+3=4, not -2, so not D.

For a cone, if the radius was quadrupled and the slant height was reduced to 1/6 of its original size what would be the formula

Paladinen [302]

Let $r$ be the radius of the cone's base and $\ell$ the slant height.

The surface area of a cone is

$A=\pi r^2+\pi r\ell$

If the radius is quadrupled ( $r\to4r$ ) and the slant height scaled by a factor of $\dfrac16$ , then the new area is

$A=\pi(4r)^2+\pi (4r)\left(\dfrac\ell6\right)$
$A=16\pi r^2+\dfrac23\pi r\ell$
