Answer:

y = (x-5)²+7

Step-by-step explanation:

i graphed x²-10x+32 and found the vertex is at (5,7)

i used the y-intercept as a point on the curve in the formula:

y = a(x-h)²+k

32 = a(0-5)²+7

subtract 7 from each side to get:

25 = 5²a

25 = 25a

a = 1

y = (h-5)² + 7

A cube has a volume of 216 cubic inches. What is the length of each edge of the cube?

KatRina [158]

Volume of a cube = (edge)^3

In this problem,

Volume = 216in^2

Edge = ?

Let's plug our values into the formula above.

216in^3 = (edge)^3

Take the cbrt of both sides.

6in = edge

The length of each edge = 6in

Express 0.003597 to three significant figures

coldgirl [10]

Answer:

0.00360.

Step-by-step explanation:

Leading zeros in a number are not significant, so your number has four significant figures.

You must drop the 7 from 0.003597.

Since 7 is greater than 5, you must add 1 to the 9

$\begin{array}{r|l}1& \\0.00359 &\text{7}\!\!\!\!\diagup \\\mathbf{0.00360} & \\\end{array}$
