Which function represents the difference. d(x). in the number of customers visiting the two shops?
a. d(x) = 0.002x +1.01x2 - 4x + 13
b. d(x) = 0.002x2 +0.99x2 + 4x - 13
c. dx) = 0.002x2 -1.01% +4% - 13
d. dix) = 0.002x3-0.99x2 - 4x + 13

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

the answer is 8/21

hope this

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
