Hi there!
[tex]\large\boxed{x = -9, 0}[/tex]
Find the zeros using factoring:
f(x) = x³ + 9x²
Factor out the common term, or x²:
f(x) = x²(x + 9)
Set each factor equal to 0:
x² = 0
x = 0
x + 9 = 0
x = -9
The zeroes are -9, 0.

A store owner asks each person to write "Yes" or "No" on a slip of paper as
they leave, secretly writing down whether they were happy with their
experience. At the end of the day, the owner selects 12 slips at random and
looks at them. These were the results:
yes, yes, yes, no, yes, no, yes, yes, no, yes, no, yes
Part 1: Estimate the proportion of all shoppers who were haphy with their
experience that day. Enter your response as a decimal.
The estimated proportion of all shoppers who were happy with their experience that day and said yes is 0.667.
What is random sample?Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.

[tex]p'=\dfrac{x}{n}[/tex]
Here, x is the number of success and n is the sample size. Here, the sample size is 12 and number of success (yes) is 8. Thus, the estimated proportion is:
[tex]p'=\dfrac{8}{12}\\p'=0.667[/tex]
Thus, the estimated proportion of all shoppers who were happy with their experience that day and said yes is 0.667.

6 Which equation has a solution of s = 9.5 ? F -5s = -47.5 G -3 + s = 12.5 H --2s 19 J –1 + s = 10.5
Answer:
F. -5s = -47.5
Step-by-step explanation:
F. -5s = -47.5
s = -47.5 / -5
s = 9.5
This is the correct option
G. -3 + s = 12.5
s = 12.5 + 3
s = 15.5 (Incorrect option)
J. –1 + s = 10.5
s = 10.5 + 1
s = 11.5 (Incorrect option)

A camp director developed the function m(c) = 12c + 80 to model the total cost of taking c campers on a field trip to the movies.
In the camp director’s function, the number of campers is the _______ variable and the total cost of the trip _________
1. ( independent, dependent )
2. ( changes by a constant factor per camper, Changes by a constant amount per camper )
.
Answer:
(a) Independent variable
(b) The constant factor is 12
Step-by-step explanation:
Given
[tex]m(c) = 12c + 80[/tex]
c = campers
m = total cost
Solving (a) What type of variable is the number of campers (c)
The total cost (m) is dependent on the number of campers (c) for its own value.
In other words, if c changes from 5 to say 7, the value of m will also change.
This implies that the number of campers is an Independent variable
Solving (b): Constant factor
This in other words means, rate of change (or slope)
A linear function is:
[tex]y = ax + b[/tex]
Where a represents the slope
By comparison with: [tex]m(c) = 12c + 80[/tex]
Hence, the constant factor is 12
Answer:
dependent, changes by a constant factor per camper.

Answer:
132 m²
Step-by-step explanation:
overall area = 12 m x 12 m = 144 m²
area of path = 1 m x 12 m = 12 m²
144 m² - 12 m² = 132 m²

I need help finding the area and perimeter to this question. Pls help!! Thank you!
Answer:
Perimeter: 50.27
Area: 201.06
Step-by-step explanation:
The perimeter (circumference) is radius times pi times 2
This would be 8 times pi tomes 2 and when you do that you get 50.27
For the area you would do radius squared times pi
This would be 8 squared times pi which is 201.06

Answer:
4.5/16+6/16=4.5+6/16
=10.5/16
Step-by-step explanation:
Here you can see denominator in both the side are same and operation sign between them is plus, therefore you can take denominator as is it.
Then add numerator and divide by denominator which is 16. Answer is 10.5/16 since you have to simplify only.

DONE
Answer:
275, 375, 475
Step-by-step explanation:
First, find the slope using the two pairs of values given.
Number of days = x
Total number of trophies = y
Using (3, 80) and (7, 180),
Slope = ∆y/∆x = (180 - 80)/(7 - 3) = 100/4 = 25
Slope/unit rate = 25 trophies per day
Multiply 25 by each given number of days to get each corresponding total number of trophies won.
Thus:
✔️Number of days = 11
Total number of trophies won = 11*25 = 275
✔️Number of days = 15
Total number of trophies won = 15*25 = 375
✔️Number of days = 19
Total number of trophies won = 19*25 = 475
Answer:
280

If he gets 100 trophies every 4 days then you just add 100 to each column because in each one the days are increasing by 4
