Answer:

C. f(x) = x³ + 10x² + 7x - 18

Step-by-step explanation:

If the function has a factor of x + 9, then the function will have a zero output at x = -9

<u>Lets verify:</u>

A. f(-9) = (-9)³ - 8*(-9)² - 11*(-9) + 18 = -1260, No
B. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 27 = -9, No
C. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 18 = 0, Yes
D. f(-9) = (-9)³ - 8*(-9)² + 11*(-9) + 27 = -1449, No

Answer: B and C

Step-by-step explanation:

404 + 50 + 50 = 504

you are buying 144 magazines total

504/144 = cost of one magazine

cost of one = 3.50

you are paying $60 a year for 12 years

60 x 12 = 720

720/144 = 5

5 - 3.50 = 1.50

120x + 180x = 1080

300x = 1080

x = 1080/300

x = 3.6

3.6 x 60 = 216

In 2018, the number of students at The Villages High School was 975 and is increasing at a rate of 2.5% per year. Write and use

avanturin [10]

Answer:

$A(t)=975(1.025)^t$

In 2025,the number of students at the villages high school=1159

Step-by-step explanation:

We are given that in 2018

Number of students at the villages high school=975

Increasing rate,r=2.5%=0.025

We have to write and use of exponential growth function to project the populating in 2025.

$A_0=975,t=0$

According to question

Number of students at the villages high School is given by

$A(t)=A_0(1+r)^t$

Substitute the values

$A(t)=975(1+0.025)^t=975(1.025)^t$

t=7

Substitute the value

Then, the number of students at the villages high school in 2025

$A(7)=975(1.025)^7=1158.96\approx 1159$
