Answer:
monthly payment: $528.39interest paid: $3,703.40Step-by-step explanation:
The monthly payment is given by the amortization formula:
A = P(r/12)/(1 -(1 +r/12)^(-12t))
where the annual interest rate is r for t years on loan value P.
Filling in the given information, we find the monthly payment to be ...
A = $28000(0.05/12)/(1 -(1 +0.05/12)^(-12·5)) ≈ $528.39
The monthly payment is $528.39.
__
The total amount repaid is ...
($528.39/mo)(60 mo) = $31,703.40
The interest paid is the difference between this and the loan amount:
interest paid = $31,703.40 -28,000 = $3,703.40
The total interest paid is $3,703.40.

2h + s = 180
3h + s = 230
Subtracting equation 1 from equation 2 gives
h = 50
Substitute for h in equation 1
2 x 50 + s = 180
So s = 80
The cost formula is C(h) = 50h + 80

he graph shows the total number of participants in a town's recreation program at the end of every year since the year 2000.
The line of best fit for the data is given by the equation y=13x+50, where y is the total number of participants x years after the beginning of the year 2000.
Which statement correctly interprets the slope of the line of best fit?
The rate of change is 1 new participant every 13 years.
The rate of change is 13 new participants every 13 years.
The rate of change is 13 new participants every year.
The rate of change is 50 new participants every year.
Answers
Answer:
The rate of change is 13 new participants every year.
Step-by-step explanation:
y=13x+50
This is in the form y = mx+b where m is the slope and b is the y intercept
x is the number of years so for every year increase we gain 13 new participants

Which equation could be used to find the total.
A) y=2.50x
B) y=12.50x
C) y=2.50x + 10
D) y=2x-10
Answers
Answer:
C) y = 2.50x + 10
Step-by-step explanation:
Equation C is saying:
total cost = 2.50(number of games) + $10 entery fee
Hope this helps :)
Answer is C
As it say to find total cost and y is given as total cost
As x is number of games and charge per game is 2.50 so it’s becomes 2,50x
Plus you have to add one time entrance fee which is $10.
So the equation becomes
y= 2.50x + 10

The exponential growth function to model represents as P = 236,000 (1+ 0.04)⁹ and 335,902 people in 2009.
What is the exponential growth function?The exponential growth function is given by:-
y = A(1 +r)ⁿ
where r is the rate of growth and A is the initial amount and n is the time period.
Let t represent the number of years since 2000 and P represent the population.
The population of a city is increasing at a rate of 4% each year. In 2000, there were 236,000 people in the city.
Put A = 236,000 , r = 0.04 and t = 9, we get
P = 236,000 (1+ 0.04)⁹
P = 335,902
Hence, the exponential growth function to model represents P = 236,000 (1+ 0.04)⁹ and 335,902 people in 2009.

The measure of the angle of depression from the top of a 270-meter building to a park bench on the ground is 36°45′. How far away is the park bench from the building? Round to the nearest whole number.
Answers
Answer:
202 m
Step-by-step explanation:
Given :
Angle of depression, θ = 36°45' ; 45/60 = 0.75 = 36 + 0.75 = 36.75°
The height, h = 270
The distance of park bench from the building, d is given by :
Tan θ = opposite / Adjacent
Tan 36.75 = d / 270
d = 270 * Tan 36.75
d = 201.61856
d, distance of Park bench from building is 202 m

Given that y varies directly as x when y = 2 and x = -12, find x when y = 5.
Answers
Answer:
x = -30
Step-by-step explanation:
Use the direct variation equation, y = kx
Plug in 2 as y and -12 as x, and solve for k:
y = kx
2 = k(-12)
-1/6 = k
So, the equation is y = -1/6x
Plug in 5 as y and solve for x:
y = -1/6x
5 = -1/6x
-30 = x
So, when y = 5, x = -30
Use a double integral to find the area of the following regions. The region bounded by all leaves of the rose r=2cos3θ
Answers
Answer:
Hence the area of the region bounded by all leaves of the rose is [tex]\pi[/tex].
Step-by-step explanation:
Here,
[tex]2 cos (3\Theta )=0\\\Rightarrow cos(3\Theta)=0\\\Rightarrow cos(3\Theta )=cos\left (\frac{\pi }{2} \right )\\\Rightarrow \Theta =\left (\frac{\pi }{6},-\frac{\pi }{6} \right )[/tex]
Now consider for one leaf of rose:-
[tex]Area = 3\int_{-\frac{\pi }{6}}^{\frac{\pi }{6}}\frac{r^{2}}{2}d\Theta \\\\ = \frac{3}{2}\int_{-\frac{\pi }{6}}^{\frac{\pi }{6}}4 cos^{2}\left ( 3\Theta \right ) d\Theta \\\\ = \frac{12}{2}\int_{-\frac{\pi }{6}}^{\frac{\pi }{6}} \frac{cos(6\Theta +1)}{2}d\Theta\\\\ =\frac{6}{2}\left [ \frac{sin(6\Theta +\Theta )}{6} \right ]_{-\frac{\pi }{6}}^{\frac{\pi }{6}}\\\\ =3\times \left [ \frac{\pi }{6}+\frac{\pi }{6} \right ]\\\\ =3\times \frac{2\pi }{6}\\\\ = \pi[/tex]

b. Find the margin of erro
Answers
Answer:
a) The 98% Confidence Interval for the proportion of all students that prefer ebooks is (0.55, 0.65).
b) The margin of error is of 0.05.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In a sample of 400 students, 60% of them prefer eBooks.
This means that [tex]n = 400, \pi = 0.6[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.054[/tex].
Margin of error -> Question b:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 2.054\sqrt{0.6*0.4}{400}}[/tex]
[tex]M = 0.05[/tex]
The margin of error is of 0.05.
A.Find 98% Confidence Interval for the proportion of all students that prefer ebooksb.
Sample proportion plus/minus the margin of error.
0.6 - 0.05 = 0.55
0.6 + 0.05 = 0.65
The 98% Confidence Interval for the proportion of all students that prefer ebooks is (0.55, 0.65).

D. Square root of 16
Step-by-step explanation:
Rational numbers are numbers that have simple answers. It is also considered as fractions, Integers, and possible square roots.
- If you chose the square root of 2 = 1.41
- Pi has a value of 3.14, It's not a fraction nor an integer so it's an Irrational number
- Square root of 10 is 3.16
- So Square root of 16 is 4 which is a regular number and a possible square root.
