We have,
Looking at the options:
A.
3, 6, 9, 12,... is a geometric sequence with a common ratio of 2.
Each term is found by multiplying the previous term by 2.
B.
2, 3, 5, 9, 17 is not a geometric sequence because there is no constant ratio between terms.
C.
4, 2, 1, 1/2, 1/4 is a geometric sequence with a common ratio of 1/2.
Each term is found by multiplying the previous term by 1/2.
D.
3,-15, -33, -51, -69, is not a geometric sequence because there is no constant ratio between terms.

find the zeros of the function by factoring f(x)=x^2+16x+60
Please show work if you can
Answer:
-6 and -10
Step-by-step explanation:
First find two numbers that multiply to 60 and add up to 16
these numbers are 6 and 10
then write the numbers in factored form: (x+6) (x+10)
Then set each one equal to zero and solve to find the zeros of the function
x+6=0 --> x=-6
x+10=0 --> x=-10
the zeros of the function are -6 and -10

Answer:
The HCF of 130, 325 and 845 is equal to 65.
Step-by-step explanation:
We need to find the HCF of 130, 325 and 845.
First, we see the prime factors of the above numbers i.e.
The factors of 130 are: 1, 2, 5, 10, 13, 26, 65, 130
The factors of 325 are: 1, 5, 13, 25, 65, 325
The factors of 845 are: 1, 5, 13, 65, 169, 845
Then the greatest common factor is 65. So, the HCF of 130, 325 and 845 is equal to 65.

A) Write the vertex form by substituting in values for x, y, h, and k, and then solve for a. Show your work. (10 points)
Answer:
[tex]a=-\frac{1}{8}[/tex]
Step-by-step explanation:
Given
See attachment for graph
Required
Write the vertex form and then solve for
The general equation is:
[tex]y = a(x - h)^2 + k[/tex]
From the attachment, the vertex is at:
[tex](h,k) = (24,50)[/tex]
i.e.
[tex]h = 24; k= 50[/tex]
Considering point:
[tex](x,y) = (4,0)[/tex]
i.e.
[tex]x=4;y=0[/tex]
Substitute these values in [tex]y = a(x - h)^2 + k[/tex]
[tex]0 = a(4 - 24)^2 + 50[/tex]
[tex]0 = a(- 20)^2 + 50[/tex]
[tex]0 =a(400) + 50[/tex]
[tex]0 = 400a + 50[/tex]
Solve for a
[tex]400a = -50[/tex]
Make a the subject
[tex]a=-\frac{50}{400}[/tex]
[tex]a=-\frac{1}{8}[/tex]
Answer:
y = a(x - h)^2 + k
h = 24, k = 50, x = 4, y = 0
0 = a(4 - 24)^2 + 50
0 = a(-20)^2 + 50
0 = a(400) + 50
0 = 400a + 50
400a = -50
a = - 50/400
a = - 1/8

You have a coupon for an additional 10% off the price of any sale item at a store. The store has put a laptop on sale for 25% off the original price of $750. What is the price of the laptop after both discounts?
Answer:
$506.025
Step-by-step explanation:
$750 - 25% = $750 - $187.5
$562.25 - 10% = $562.25 - 56.225
f(1)= -34
f(n)=f(n−1) - 3
Find an explicit formula for f(n).
Answer:
f(n) = -34 -3(n - 1)
Step-by-step explanation:
The explicit formula for f(n) is given below:
Given that
f(1)= -34
f(n)=f(n−1) - 3
Based on the above information
f(n) = a1 +d(n -1)
a1 = -34
d = -3
So
f(n) = -34 -3(n - 1)
This above represent an explicit formula
Carlotta thinks that 3y + 5y3 is the same as 8y4. Which statement shows that it is NOT the same?
3y + 5y ≠ 8y
3y + 5y3 = 8y3
3(4) + 5(4)3 ≠ 8(4)4
3(4) • 5(4)3 ≠ 8(4)4
Answer:
C. 3(4) + 5(4)³ ≠ 8(4)⁴
Step-by-step explanation:
3y + 5y³ is NOT the same as 8y⁴
Assume y = 4
Not equal to sign ≠
3y + 5y³ ≠ 8y⁴
3(4) + 5(4)³ ≠ 8(4)⁴
12 + 20³ ≠ 32⁴
12 + 8000 ≠ 1,048,576
8012 ≠ 1,048,576
The statement which shows that 3y + 5y³ is NOT the same as 8y⁴ is 3(4) + 5(4)³ ≠ 8(4)⁴
write 75m:125cm in its simplest form
Answer: should be 3/5
Step-by-step explanation:
Divide both the numerator and denominator by the GCD
75 ÷ 25
125 ÷ 25 if im wrong sorry
The ratio of 75m : 125cm in its simplest form is 60 : 1.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, Two similar quantities.
We know 75m = 75×100 = 7500 cm.
Therefore, The ratio between them is,
7500 : 125.
1500 : 25.
300 : 5.
60 : 1.

O The subjects in the study are not representative of the population, because some members of the population were not able to participate in the study.
O The subjects in the study are not representative of the population, because some members of the population refused to take part in the study.
Answer:
The subjects in the study are not representative of the population, because some members of the population were not able to participate in the study.
Step-by-step explanation: i got it right on the test
A sample is said to exhibit undercoverage bias, if some of the portion or category of the population are not adequately represented or exempted from the selected sample. Hence, undercoverage bias exists because, The subjects in the study are not representative of the population, because some members of the population were not able to participate in the study.
Undercoverage bias produces non - representative samples as some category of the population may have been exempeted from the study. Hence, option C is correct.Undercoverage translates that the opinion of some members of the population were not even considered. Hence, the introduction of undercoverage bias.
