Can someone help me on this
mr Goodwill [35]

Since this is a right triangle, we can you the pythagorean theorem.

a^2 + b^2 = c^2

In this case,

a = 6

b = ?

c = 10

We need to substitute our values into the pythagorean theorem.

(6)^2 + b^2 = (10)^2. Reduce everything to its simplest form.

36 + b^2 = 100. Subtract 36 from both sides.

b^2 = 64. Take the square root of each side.

b = 8.

John bought s sponges. There were 10 sponges in each package. Write an expression that shows how many packages John bought.
vekshin1
The expression would be s/10. 
i.e. If you have 20 sponges and 10 sponges are in each package, the number of packages would be 2 because of 20/10.

ANSWER:

\text{center}=(\frac{3}{2},-\frac{1}{2})

STEP-BY-STEP EXPLANATION:

The center of the circle would be the mean value between the end points, and we can calculate it like this:

\begin{gathered} (M_1,M_2)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ \text{replacing} \\ (M_1,M_2)=(\frac{-2+5_{}}{2},\frac{-4+3_{}}{2}) \\ (M_1,M_2)=(\frac{3_{}}{2},-\frac{1_{}}{2}) \end{gathered}
