Answer:
A) i = $4488.75
B) Amount paid per month = $785.45
Step-by-step explanation:
A) Formula for simple interest is;
i = PRT
We are given;
Principal; P = $28500
Rate; R = 4.5% = 0.045
Time; T = 42 months = 42/12 years
Thus;
i = (28500 × 0.045 × (42/12))
i = $4488.75
B) Since interest was $4488.75 and principal is $28500,then total he paid after 42 months is;
Total = 28500 + 4488.75
Total = $32988.75
Amount paid per month = 32988.75/42 = $785.45

Evaluate the following integral using trigonometric substitution
Integral underroot dx/ 9-x^2
Answer:
The result of the integral is:
[tex]\arcsin{(\frac{x}{3})} + C[/tex]
Step-by-step explanation:
We are given the following integral:
[tex]\int \frac{dx}{\sqrt{9-x^2}}[/tex]
Trigonometric substitution:
We have the term in the following format: [tex]a^2 - x^2[/tex], in which a = 3.
In this case, the substitution is given by:
[tex]x = a\sin{\theta}[/tex]
So
[tex]dx = a\cos{\theta}d\theta[/tex]
In this question:
[tex]a = 3[/tex]
[tex]x = 3\sin{\theta}[/tex]
[tex]dx = 3\cos{\theta}d\theta[/tex]
So
[tex]\int \frac{3\cos{\theta}d\theta}{\sqrt{9-(3\sin{\theta})^2}} = \int \frac{3\cos{\theta}d\theta}{\sqrt{9 - 9\sin^{2}{\theta}}} = \int \frac{3\cos{\theta}d\theta}{\sqrt{9(1 - \sin^{\theta})}}[/tex]
We have the following trigonometric identity:
[tex]\sin^{2}{\theta} + \cos^{2}{\theta} = 1[/tex]
So
[tex]1 - \sin^{2}{\theta} = \cos^{2}{\theta}[/tex]
Replacing into the integral:
[tex]\int \frac{3\cos{\theta}d\theta}{\sqrt{9(1 - \sin^{2}{\theta})}} = \int{\frac{3\cos{\theta}d\theta}{\sqrt{9\cos^{2}{\theta}}} = \int \frac{3\cos{\theta}d\theta}{3\cos{\theta}} = \int d\theta = \theta + C[/tex]
Coming back to x:
We have that:
[tex]x = 3\sin{\theta}[/tex]
So
[tex]\sin{\theta} = \frac{x}{3}[/tex]
Applying the arcsine(inverse sine) function to both sides, we get that:
[tex]\theta = \arcsin{(\frac{x}{3})}[/tex]
The result of the integral is:
[tex]\arcsin{(\frac{x}{3})} + C[/tex]
Solve the equation.

The graph of a function F is shown below use the graph of the function to find it’s average rate of change from x= -4 to x= -2.
Simplify your answer as much as possible.
Answer:
avg rate of change = -2/3
Step-by-step explanation:
f(x) = -1/3(x-2)²+4
f(-4) - f(2) / [-4-(-2)]
= -8 - (-28/3) / -2
= (-24/3 + 28/3) / -2
= 4/3 · -1/2
= -4/6 or -2/3

Answer
Roundworm is 9ft long and the tapeworm is 60 feet long
Step-by-step explanation:
If we turn this into an algebraic equation we get 8x-3=69 with 8x being x + 7x because we know that the tape worm is about 7 times longer than the round worm and the roundworms length would be x here. We have the -3 because it is 3 minus 7 times the total length. We do this and eventually end up with x = 9 which is the length of the roundworm. We multiply that by 7 to get 63 and subtract 3 to get 60. If you want to check if this is right do 60+9 and you'll get 69 which is the total of them end to end. (also 69 funny haha)

The sum of 3 times the value of x and 2 is equal to less than 5 times the value of x. Which equation can be used to find the value of x?
A. 3x+2=4-5
B. 2x+3=4-5x
C. 3x+2=5x-4
D. None of these
sum is the answer to addition problem.
less than is subtraction and "times" is multiplication.
So we have
3x+2=5x-4
So the answer is C.
Also, i'm bored so imma solve it.
3x+2=5x-4
-2 -2
3x=5x-6
-5x -5x

Armelia wants to paint three walls in her family room, wwo walls are 26 feet long by 9 feet wide. The other wall is 18 feet Hong by 9 feet wide. Each gallon of paint covers about 250 square feet. How many gallons of paint should Amella buy to paint the walls?
Answer: Wall 1 & 2 : 26 ft by 9 ft
Wall 3 : 18 ft by 9 ft
Area 1 : 26 ft x 9 ft = 234 ft²
Area 2 : 26 ft x 9 ft = 234 ft²
Area 3 : 18 ft x 9 ft = 162 ft²
Total Area : 234 ft² + 234 ft² + 162 ft² = 630 ft²
1 Gallon = 250 ft²
630 ft² ÷ 250 ft² per gallon = 2.52 gallons

Sal had $95 in his wallet. Then he bought a hat for $22 and a pair of jeans for $35 at the store. On his way home, Sal stops by the gas station to put gas in his tank using the money he has
left. If gas costs $3 per gallon, and x represents the number of gallons of gas Sal is able to purchase, which statements are true?
Select all that are correct.
Sal can determine the number of gallons of gas that he can purchase using the inequality 57x + 3 5 95
The number of gallons of gas that Sal can purchase can be represented by the inequality 3x S 38
Sal can purchase 13 gallons of gas or fewer.

The equation Negative one-half(x + 1) = (y – 5)2 is represented by which graph?
its Not A or B
Answer:
Step-by-step explanation:
one-half(x + 1) = (y – 5)^2, written symbolically, is (1/2)(x - [-1]) = (y - 5)^2
or x + 1 = 2(y - 5)^2 (after multiplying all terms by 2). Because the y term is squared, we know immediately that the graph is a horizontal (not vertical) parabola.
This equation (immediately above) can be written as
x = 2(y - 5)^2 - 1
The standard equation of a horizontal parabola with vertex (h, k) is x = c(y - k)^2 + h. Comparing this to the given quadratic:
we see that k = 5 and h = -1. This tells us that the vertex of this graph is (-1, 5), and that the graph is stretched horizontally because c = 2 is greater than 1.
To graph this, it's best to make a short table of points, as follows, remembering that y is the independent value and x depends on y through the equation given above.
y x = 2(y - 5)^2 - 1 (x, y)
0 x = 49 (49, 0)
2 x = 2(-3)^2 - 1 (17, 2)
1 x = 2(-4)^2 - 1 (31, 1)
vertex (already found) (-1, 5)
The graph of equation 1/2(x+1)=[tex](y-5)^{2}[/tex] looks like graph of a horizontal parabola.
What is equation?Equation is relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It is of many types like linear equation, quadratic equation, cubic equation, etc.
How to graph equation?one-half(x + 1) = (y – 5)^2, written symbolically, is (1/2)(x - [-1]) = [tex](y-5)^{2}[/tex]
or x + 1 = 2[tex](y-5)^{2}[/tex]. Because the y term is squared, we know immediately that the graph is a horizontal (not vertical) parabola.
This equation can be written as
x = 2[tex](y-5)^{2}[/tex] - 1
The standard equation of a horizontal parabola with vertex (h, k) is
x = c[tex](c-k)^{2}[/tex] + h. Comparing this to the given quadratic:
we see that k = 5 and h = -1. This tells us that the vertex of this graph is (-1, 5), and that the graph is stretched horizontally because c = 2 is greater than 1.

Step-by-step explanation:
A consumer group studied two different manufacturers of cars, J and K, to investigate differences in gas
mileage for cars made by the two manufacturers. For a similar type of car, a random sample of 15 cars
from J and a random sample of 12 cars from K were selected, and the gas mileages, in miles per gallon
(mpg), were recorded. The difference in the sample mean gas mileages was used to construct the 90
percent confidence interval (3.5,5.7).
Assuming all conditions for inference were met, which of the following is a correct interpretation of the
interval?
А
The probability is 0.90 that the difference in sample means for gas mileage for the two
car manufacturers is between 3.5 mpg and 5.7 mpg
B
The probability is 0.90 that the population mean difference in gas mileage for the two car
manufacturers is between 3.5 mpg and 5.7 mpg
About 90 percent of the differences in gas mileage for the two car manufacturers are
between 3.5 mpg and 5.7 mpg.
D
We are 90 percent confident that the difference in sample means for gas mileage for the
two car manufacturers is between 3.5 mpg and 5.7 mpg.
E
We are 90 percent confident that the population mean difference of gas mileage for the
two car manufacturers is between 3.5 mpg and 5.7 mpg.
