The deal mart sells replacement cell phone chargers. Their earned income from selling n number of chargers is I(n)=34.78n. The company also has costs associated with producing and disturbing the phone chargers according to the function C(n)=24,160 + 3.25. Write a function, P(n), to represent the profit the company makes is Profit=income-cost

b is the answer that makes most sense

step-by-step explanation:

4 + 5 7/9= 9 7/9

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
