The face of a cell phone measures 5.55 inches by 1.9 inches. find the perimeter of the regular face

The face of a cell phone measures 5.55 inches by 1.9 inches and the perimeter of the regular face is 14.9  inches

Solution:

From question given that

Given length = 5.55 inches

Width = 1.9 inches

We need to find the perimeter of the regular face using the given data. Generally cell phone is in rectangular shape.

Perimeter of a rectangle can be found out by using the below formula,

P = 2(l + w)

Where  

l is the length of the rectangle

w is the width of the rectangle

p = 2(5.55+1.9)  = 14.9

The perimeter of the regular face is 14.9. inches

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

it has the same slope and a different y-intercept

hope this : )
