The vertex of this parabola is at (-4, -1). When the y-value is 0, the x-value is 2. What is the coefficient of the squared term

satela [25.4K]

$\bf \qquad \textit{parabola vertex form}\\\\
\begin{array}{llll}
\boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\
x=a(y-{{ k}})^2+{{ h}}
\end{array} \qquad\qquad vertex\ ({{ h}},{{ k}})\\\\
-------------------------------\\\\
y=a(x-(-4))^2-1\implies y=a(x+4)^2-1
\\\\\\
\textit{now, we also know that }
\begin{cases}
y=0\\
x=2
\end{cases}\implies \underline{0}=a(\underline{2}+4)^2-1$

solve for "a"

Mr.Choi has a class of 17 students. He can spend $17 on each student to buy math supplies for the year. He first bugs all his st

Reika [66]

Multiply 17(number of students) and 17(amount he’s spending on each student)
So 17x17=289
Then subtract what he used which is 97.41
So 289-97.41= 191.59

He has $191.59 left

Angela has a cube with a length of one yard. Maya has a cube with a length of one meter. What do the two cubes have in common? L

Vlad1618 [11]

<h3><u>1) </u><u>Both cubes have approximately equal sides</u><u>.</u></h3><h3><u>2) The volume of both cubes is approximately equal .</u></h3>

Step-by-step explanation:

Here, let us assume there are two cubes A and B.

The side length of cube A = 1 yard

The side length of cube B = 1 meter

Now,as we know: 1 meter = 1.09361 yards ≈ 1 yard

So, we can say that, approximately, <u>both cubes have equal sides</u>.

Now, Volume of a Cube = (Side)³

Since, both cubes have approximately equal sides,

⇒Volume of cube A ≈ Volume of cube B

Hence, both cubes have approximately equal volume.

Answer:

The rule is f(x) = 2^(2x).

Step-by-step explanation:

Note that 4 = 2^2, 16 = 4^2, 64 = 8^2, 256 = 16^2 and 1024 = 32^2

and the first numbers in the ordered pairs are 1 , 2 ,3, 4, 5

compare this with 2, 4 , 8, 16 , 32.

We see that the rule for this is 2^x where x is the sequence number.

So the rule for the original ordered pairs is (2^x)^2.

= 2^2x.
