Answer:
5,-5,-2 are the solutions
Step-by-step explanation:
f(x)=0 thus, either:
1) x+5 = 0 and thus x= -5
or
2) x+2=0
thus x= -2
or
3) x - 5 = 0
thus x = 5
notice that the other bracket can be written as:
(x+2)(x-5)

Miriam’s study group received test scores of 96, 81, 82, 99, 94, 92, 95, 82, and 80. find the mean and median scores. the mean is . the median is .
Answers
The mean, median, and mode of the given data are 89, 92 and 82 respectively.
Measure of dispersionThe measures of dispersion that we have are the mean, median and the mode.
The mean is the average of the given data
Mean = Sum/sample size
Mean = 96+81+82+99+94+92+95+82+80/9
Mean = 801/9
Mean = 89
Determine the medianMedian is the middle value after rearrangement
80, 81, 82, 82), 92, (94, 95, 96, 99
Hence the medianof the data is 92
Calculate the modeMode is the number occuring the most. Since 82 occurs the most, hence the mode is 82
The mean, median, and mode of the given data are 89, 92 and 82 respectively.

The exact circumference of a circle is 18π inches. What is the approximate area of the circle? Use 3.14 for π. Round to the nearest hundredth if necessary.
Answers
Answer:
254.34
Step-by-step explanation:
Given the circumfrence we can find the diameter b dividing by pi which will get us 18. We can then divide by 2 to get 9 which is our radius. To get the area we will square our radius :81 and multiply it by pi to get 254.34.
Find the nth term of this number sequence

help please !!
Answers
Answer:
[tex]a_{n}[/tex] = 3n + 4
Step-by-step explanation:
there is a common difference between consecutive terms , that is
10 - 7 = 13 - 10 = 16 - 13 = 3
this indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 7 and d = 3 , then
[tex]a_{n}[/tex] = 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4
Answer:
The nth term = 3n + 4.
Step-by-step explanation:
The formula for the nth term of an arithmetic progression is a(n) = dn + a(1) - d.
So this breaks down simply to,
a(n) = dn + a(1) - d a(n) = 3n + 7 - 3 a(n) = 3n + 4

possible?
A. 40,320
B. 10,080
OC. 1,680
D. 70
Answers
Answer: 70
Step-by-step explanation:
you would do 8C4
If there are 8 pieces to choose from, there are 1,680 different ways distinct displays are possible.
How many ways k things out of m different things (m ≥ k) can be chosen if order of the chosen things doesn't matter?[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]
This is called permutation of k items chosen out of m items (all distinct).
To find the Ways can 8 pieces of art in the front window be arranged in the display window.
Let us use permutation to find the number of ways can 8 pieces of art in the front window be arranged in the display window.
here we have
n= 8
r= 4
substituting the values,
[tex]^nC_r = \dfrac{n!}{ (n-r)!}\\\\^8C_4 = \dfrac{8!}{ (8-4)!}\\\\^8C_4 = \dfrac{8!}{ (4)!}\\\\^8C_4 = 8 \times 7 \times 6\times 5\\\\^8C_4 =1680[/tex]

To find our y-intercept. Plugin x = 0 into the equation to get y.

f(x) = 2(4x+3)(x-1)
x = -3/4 , 1
Substitute -1 into the equation to solve f(-1).
