Answer:

= -5/4

Step-by-step explanation:

To find the slope, we can use the slope formula

m = ( y2-y1)/(x2-x1)

= ( -9 - -4)/( -4 - -8)

= ( -9 +4)/( -4 +8)

= -5/4

Find volume of cylinder. circumference is 9 and height is 15

MAXImum [283]

Answer:

The volume is 945.26

Step-by-step explanation:

The volume is 945.26 (this is only if this is a right cylinder)

volume of right cylinder formula = πr^2h

r = 4.5

We know that the circumference is 9.

circumference = 2πr

so, you would have to divide 9 by 2 to get the radius which is 4.5

h= 15 (already given)

then just plug it in!

π4.5^2(15)

π4.5^2 = 20.25π

20.25 x π = 63.6172512352

63.6172512352 x 15 ≈ 945.26

Answer:

Grace weighed 167 pounds before she started her exercise program.

Step-by-step explanation:

Given,

Weight lost by Grace = 45 pounds

Weight of Grace after exercise weeks = 122 pounds

Let,

x represents the weight of Grace before she started the exercise program.

Loss means subtraction, therefore,

We will subtract the lost weight from original weight.

Original weight - Weight lost = Weight after exercise weeks

$x - 45 = 122$

Adding 45 on both sides

$x - 45+ 45= 122+45$

$x=167 pounds$

Grace weighed 167 pounds before she started her exercise program.
