If 4 is a root of f(x), which of the following is a factor of f(x)?
(x+4)
neither (x+4) nor (x-4)
(x-4)
(x+4) and (x-4)
Answers
Given:
4 is a root of f(x).
To find:
A factor of f(x).
Solution:
We know that, if c is a root of a function f(x), then (x-c) is a factor of f(x).
In the given problem, 4 is a root of f(x).
So, we have c=4.
By using the above property we can say that, (x-4) is a factor of function f(x).
Since, (x-4) is a factor of function f(x), therefore, the correct option is C.
Nathan is opening a savings account that has a 10% simple interest rate. He deposits $75 in the account. After 5 years, he will have $112.50 in his account. How many more dollars would Nathan earn after 5 years with a 10% compounded interest rate?
Answers
Answer:
Dollars earned after 5 years = $45.79
Step-by-step explanation:
Given that:
Initial money deposited in account = $75
Time for which the money is deposited = 5 years
Interest rate = 10%
Nature of interest = Simple Interest
Amount after 5 years = $112.50
To find:
Total money earned after 5 years if the interest is compounded ?
Solution:
Formula for amount if the interest is compounded annually:
[tex]A =P(1+\frac{R}{100})^T[/tex]
Where P is the principal amount (initial money)
R is the rate of interest
T is the time
Putting all the values:
[tex]A =75\times (1+\frac{10}{100})^5\\\Rightarrow \bold{A = \$120.79}[/tex]
Total more money earned or the interest after the compounding nature =
[tex]A - P[/tex] = $120.79 - $75 = $45.79
Barb is looking at internet service plans. A local company offers a one month service plan for $39.95 for a two month service plan for $68.97 dollars how much would Barb save in 2 months if she only got two month plan instead of two one month plans enter?
Answers
Answer:
Barb would save $10.93 in 2 months if she only got two month plan instead of two one month plans.
Step-by-step explanation:
First, you need to determine the amount that Barb will pay with the one month service plan in 2 months:
$39.95*2= $79.9
Now, you need to calculate the difference between both plans:
$79.9-$68.97=$10.93
According to this, the answer is that Barb would save $10.93 in 2 months if she only got two month plan instead of two one month plans.

which of the lines graphed has a slope of 1 and a y-intercept of -3?
Answers
Answer: The attached image (Graph 4) is the correct graph.
Step-by-step explanation:
1. Find the graph with the point (0, -3), the y-intercept. This eliminates all but two graphs.
2. Out of the two graphs you have narrowed down the options to, choose the graph with the positive slope (slope of 1). Since graph 3 has a negative slope amd graph 4 has a positive slope and still satisfies the correct intercept, the 4th graph is the correct option.
The distance between two cities on a map is 3.25 centimeters. The map used a scale in which 1 centimeter represents 20 kilometers. What is the actual distance between these two cities in kilometers?
Answers
Answer:
65kmStep-by-step explanation:
Step one:
given
we are told that the distance is 3.25cm on the map
the scale is 1cm to represent 20km
Required
the actual distance
Step two
if 1cm represent 20km
then 3.25cm will represent x km
cross multiply we have
x=2.35*20
x= 65km
Hence, the actual distance between these two cities in kilometers 65km

The Probabilty of rolling a 1 on a 6 sided biased dice is 0.85
Answers
Answer:
false
Step-by-step explanation:
This statement is false. There are a total of 6 sides on a six-sided die therefore, every roll is a one in six chance of getting a single number since only one number can be obtained per roll. So that would mean that the probability is
[tex]\frac{1}{6}[/tex] or 0.16666 or 16.66%
That would be the actual probability of rolling a 1 on a single roll of a six-sided die, not 0.85

Answer:
20. AB = 42
21. BC = 28
22. AC = 70
23. BC = 20.4
24. FH = 48
25. DE = 10, EF = 10, DF = 20
Step-by-step explanation:
✍️Given:
AB = 2x + 7
BC = 28
AC = 4x,
20. Assuming B is between A and C, thus:
AB + BC = AC (Segment Addition Postulate)
2x + 7 + 28 = 4x (substitution)
Collect like terms
2x + 35 = 4x
35 = 4x - 2x
35 = 2x
Divide both side by 2
17.5 = x
AB = 2x + 7
Plug in the value of x
AB = 2(17.5) + 7 = 42
21. BC = 28 (given)
22. AC = 4x
Plug in the value of x
AC = 4(17.5) = 70
✍️Given:
AC = 35 and AB = 14.6.
Assuming B is between A and C, thus:
23. AB + BC = AC (Segment Addition Postulate)
14.6 + BC = 35 (Substitution)
Subtract 14.6 from each side
BC = 35 - 14.6
BC = 20.4
24. FH = 7x + 6
FG = 4x
GH = 24
FG + GH = FH (Segment Addition Postulate)
[tex] 4x + 24 = 7x + 6 [/tex] (substitution)
Collect like terms
[tex] 4x - 7x = -24 + 6 [/tex]
[tex] -3x = - 18 [/tex]
Divide both sides by -3
[tex] x = 6 [/tex]
FH = 7x + 6
Plug in the value of x
FH = 7(6) + 6 = 48
25. DE = 5x, EF = 3x + 4
Given that E bisects DF, therefore,
DE = EF
5x = 3x + 4 (substitution)
Subtract 3x from each side
5x - 3x = 4
2x = 4
Divide both sides by 2
x = 2
DE = 5x
Plug in the value of x
DE = 5(2) = 10
EF = 3x + 4
Plug in the value of x
EF = 3(2) + 4 = 10
DF = DE + EF
DE = 10 + 10 (substitution)
DE = 20

A. There is a positive correlation in the data set.
B. There is a negative correlation in the data set.
C. There is no correlation in the data set.
D. More points are needed to determine the correlation.
Answers
It can be said that the "there is a negative correlation in the data set". Option B is correct.
The graph shows points that are grouped together and are decreasing.
The gathered data shows that there is a possibility to get correlation between them.
The group of data is decreasing. So, the correlation of the data will be negative in nature.
Therefore, it can be said that the "there is a negative correlation in the data set". Option B is correct.
