An engineer is planning a new water pipe installation. The circular pipe has a diameter of d = 20 cm d=20 cmd, equals, 20, start text, space, c, m, end text. What is the area A AA of the circular cross section of this pipe? Give your answer in terms of pi

Step-by-step explanation:

d = 20

r = 0.5d

r = 10cm

A = πr^2 = 100π cm^2

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
