Answer:

B. g(x) = 2x² + 1

Step-by-step explanation:

<u>Even function has following property:</u>

g(x) = g(-x)

<u>It is easy to show this works with the second choice only. All the others don't work:</u>

g(x) = (x - 1)² + 1
g(-x) = (-x - 1)² + 1

This is not correct as x - 1 ≠ -x - 1 so as their squares, so g(x) ≠ g(-x)

The last two choices are not even similarly.

What is the volume of the square pyramid? Round to the nearest tenth.

Answer:

$V=718.7\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the square pyramid is equal to

$V=\frac{1}{3}b^{2}h$

we have

$b=14\ cm$ ----> the length of the base of the square pyramid

$h=11\ cm$ ---> the height of the pyramid

substitute the values in the formula

$V=\frac{1}{3}(14)^{2}(11)$

$V=718.7\ cm^{3}$

Holly bought 23 tickets to the baseball game. She got a group rate that gave her $4 off of the regular ticket price for each tic

Answer:

The regular price of the ticket was $12.

Step-by-step explanation:

Let us call $P$ the regular price of the tickets, and if she had bought tickets at this price, the total cost would have been

$23P$ .

But Holly got $4 off the regular ticket price, that means one ticket cost her

$P-4$

and if she bought 23 tickets it cost her

$23(P-4)$

and we are told this equals $184; therefore we have

$23(P-4)=184$

now we solve this equation the following way:

$23(P-4)=184$

$23P-4(23)=184$

$23P-92=184$

$23P=276$

$\boxed{ P=12}$

Thus, the regular price was $12.

Can anyone help me, please?

Answer:

So first plot the points then move it the way ( x-3, y-4)

remember for the x axis you slide left to right and we know that left is negative so you would go left 3 times and for y you would go down 4 times do it for each point.
