how to solve Davis bought a second hand cycle for $500 he spent $80 in repairs and $175 in repainting he then sold it to John fo

Ivanshal [37]

So you would need to add:

500$ + 80$ + 175$ = 755$

Since John paid 900$ then you would subtract how much he is buying it for from how much Davis spent to fix it

900$ - 755$ = 145$ (on profit Davis earned)

A rectangle has a length of 12 and a width of 400 cm what is the preimeter of the rectangle

ANTONII [103]

Answer:

Step-by-step explanation:

P = 2(L + W) ....this is the formula for perimeter of a rectangle

L = 12

W = 400

now just sub

P = 2(12 + 400)

P = 2(412)

P = 824 cm <===

Find the average rate of change of f(x) = 2x^2+6

dybincka [34]

Given:

$f(x)=2 x^{2}+6$

To find:

The average rate of change.

Solution:

Average rate of change formula:

$$\frac{f(b)-f(a)}{b-a}$

(a) <u>Average rate of change from 2 to 4:</u>

Substitute x = 4 and x = 2 in f(x).

$$\frac{f(4)-f(2)}{4-2}=\frac{(2(4)^2+6)-(2(2)^2+6)}{4-2}$

$$=\frac{38-14}{2}$

= 12

Average rate of change from 2 to 4 is 12.

(b) <u>Average rate of change from 1 to 3:</u>

Substitute x = 3 and x = 1 in f(x).

$$\frac{f(3)-f(1)}{3-1}=\frac{(2(3)^2+6)-(2(1)^2+6)}{3-1}$

$$=\frac{24-8}{2}$

= 8

Average rate of change from 2 to 4 is 8.

(c) <u>Average rate of change from -2 to 1:</u>

Substitute x = 1 and x = -2 in f(x).

$$\frac{f(1)-f(-2)}{1-(-2)}=\frac{(2(1)^2+6)-(2(-2)^2+6)}{1+2}$

$$=\frac{8-14}{3}$

= -2

Average rate of change from 2 to 4 is -2.
