Answer

square root of 32

Step-by-step explanation:

in a right triangle we can use Pythagorean theorem to find B

C^{2} =A^{2}+B^{2}  \\\\  9^{2}=7^{2}+B^{2}   \\81=49+B^{2} \\81-49=B^{2} 32=B^{2}\\ B=\sqrt{32}we substitute C for 9 and A for 7

What is the slope of the line? <br><br><br> Please help thank you
Elis [28]

Answer:

3

Step-by-step explanation:

basically slope determined from a graph like this can be solved by counting. the formula you need to use is rise/run. choose one of the orange points on the line and then count how many spaces up the next dot is. once we have our number (3), you can count how many spaces over the dot is to the right (1) this leaves you with the fraction 3/1 or 3.

also if the dot is to the left it means the slope is negative. so if the dot is 3 up and 1 to the left the slope would be -3

Answer:

The circumference is:

C=52.8\: ft

Step-by-step explanation:

The equation of the circumference of a circle is given by:

C=2\pi R

Where:

R is the radius of the circle (R=8.4 ft)

Therefore, the circumference will be:

C=2\pi*8.4

C=2(3.14)8.4

C=52.8\: ft

I hope it helps you!
