Answer:
Option (1)
Step-by-step explanation:
Exponential equation that models the increase in the number of books has been given as,
[tex]B=8700e^{0.04t}[/tex]
Here, B = Number of books
t = Number of years
Number of books after t = 3,
[tex]B=8700\times e^{0.04\times 3}[/tex]
[tex]=8700\times e^{0.12}[/tex]
= 9809.226
≈ 9809
Therefore, Option (1) will be the correct option.
Answer:
After 3 years, the library will have approximately 9,809 books.
Step-by-step explanation:
If [tex]t[/tex] represents the number of years passed, in the time of 3 years, the library shall have [tex]8700e^{0.04*3} = 8700e^{0.12}[/tex] ≈ [tex]8700*1.12749[/tex] ≈ [tex]9,809[/tex] books.

a woman is 10 times as old as her daughter. In 8 years she will be 4 times as old as her daughter. How okd is her mother now?
Answers
Answer:
48 yr. old
Step-by-step explanation:
Assume daughter is 4 and mom is 10 times her age, so mom is 40.
10 (woman) * 4 (daughter's age) = 40 yr. old mom
Present day...
40 (yr old mom) + 8 (yrs later) = 48 yr. old mom today
4 (yr old daughter) + 8 (yrs later) = 12 yr. old daughter today
So, if mom is 4 times as her daughter's age today...
48 (yr. old mom) / 12 (yr. old daughter) = 4

6 months ago, Juan used his credit card for a transaction of 128 dollars. The bank charges a rate of interest
of 50% per month compounded monthly
How much does Juan owe to the bank today?
Answers
The compound interest implies that Juan owes $163.52 today
How to determine the amount Juan owes?The given variables can be represented as:
Loan amount P = $128Rate of interest, R = 50%Time to pay back the loan, t = 6 months i.e. 0.5 yearThe amount from a compound interest can be calculated using:
A = P(1 + r/n)^nt
Also from the question, we have
n = 12
This is so because the loan is compounded 12 times in a year as a result of being compounded monthly
So, we have
A = P(1 + r/n)^nt
A = 128 * (1 + (50%/12))^(0.5*12)
Evaluate
A = 163.52
Hence, the amount owed is $163.52

An online music store charges you $5.95 for 5 songs. How much would it cost you to
buy 14 songs?
Answers
Answer:
It would cost $16.66
Step-by-step explanation:
To find the individual cost of one song you would divide $5.95 by 5 since that's what it costs for 5 songs. Each individual song costs $1.19. So then you multiply $1.19 by the 14 songs and get the answer of $16.66

Answer:
D. 21.
Step-by-step explanation:
The general form of the equation of a circle is:
(x - a)^2 + (y - b)^2 = r^2 where r is the radius.
Comparing:
(x + 5)^2 + (y + 7)^2 = 21^2
So r^2 = 21^2
making r = √21^2
= 21.

The first three cuboid prisms all use the same area formula:
A = 2(LW +H(L+W))
__
1. A = 2(3·3 +7(3+3)) = 2(9 +42) = 102 . . . cm²
2. A = 2(2·8 +10(2 +8)) = 2(16 +100) = 232 . . . in²
3. A = 2(4.9·3 +0.7(4.9 +3)) = 2(14.7 +5.53) = 40.46 . . . ft²
__
4. The area of this prism is the total of the area of the two triangular bases and the areas of the rectangular faces. For triangle legs a, b and hypotenuse c, and prism depth d, the area formula can be written as ...
A = ab +d(a+b+c)
A = (8 mm)(15 mm) +(9 mm)(8 mm + 15 mm + 17 mm)
A = (120 +9(40)) mm² = 480 mm²

Coach Elyson claims that 90% of her volleyball serves are good serves. The captain of the team thinks Coach Elyson has a lower rate of good serves. To test this, 50 of the coach’s serves are randomly selected and 41 of them are good. To determine if these data provide convincing evidence that the proportion of Coach Elyson’s serves that are good is less than 90%, 100 trials of a simulation are conducted. The team captain’s hypotheses are: H0: p = 90% and Ha: p < 90%, where p = the true proportion of Coach Elyson’s serves that are good. Based on the results of the simulation, what is an estimate of the P-value of the test?

Answers
Answer:
This is not a function, so we can not find the equation of this line.
Step-by-step explanation:
The two points form equation of a line is given by:
[tex]y-y_{1}=m(x-x_{1})[/tex]
Where:
y(1) is the y value of the first pointx(1) is the x value of the first pointm is the slopeThe first point is (3,-4) and the second point is (3,8)
Let's first find the slope. The equation of m is given by:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m=\frac{8-(-4)}{3-3}[/tex]
Here the slope is not defined, so we can not find the equation of this line, because it is not a function.
