Answer:
60
Step-by-step explanation:
50%=.50
160×.50=80
160+80=240
25%=.25
240×.25=60
60 is the final number
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

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

The sample for a study exhibits undercoverage bias. Select the statement that best describes the bias in the study. O There are not enough subjects in the sample.
O Many of the subjects in the study did not answer every question on the survey.
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.

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

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

108 divided by 2 1/2
Answer:
43.2
Step-by-step explanation:
first turn 2 1/2 into an improper fraction
(2 × 2) + 1 = 5
5/2
then turn 5/2 into a fraction
5 ÷ 2 = 2.5
now divide!
108 ÷ 2.5 = 43.2
Number equivalent to 108/2 1/2 is 43.2 .
Given,
108 divided 2 1/2
Using division property,
The rules for division are:
(1) positive × or ÷ positive = positive
(2) positive × or ÷ negative = negative
(3) negative × or ÷ negative = positive
Rule for long division method,
Divide the tens column dividend by the divisor.
Multiply the divisor by the quotient in the tens place column.
Subtract the product from the divisor.
Bring down the dividend in the ones column and repeat.
Therefore,
divide, multiply, subtract, bring down and repeat or find the remainder.
Here the required value is of :
108/2 1/2
= 108 / (5/2)
= 43.2
Hence the answer is 43.2
