Answers
Answer:
$78.01
Step-by-step explanation:
solve the equation 56(1+.037÷4)^4×9
ends up being 56(1.00925)^36
56(1.3930133899)
=78.0087
The total value of the annuity in 9 years is: $78.00
We have the following information available from the question is:
He buys an annuity with a quarterly payment of $56 that pays 3.7 interest, compounded quarterly.

What is the equation of the line that is parallel to the line 5x + 2Y=12 and passesthrough the point (-2,4) ?
Answers
Answer:
y = [tex]-\frac{5}{2}[/tex]x - 1
Step-by-step explanation:
5x + 2y = 12
2y = -5x + 12
y = [tex]-\frac{5}{2}[/tex]x + 6
y = mx + b
4 = [tex]-\frac{5}{2}[/tex] ( -2 ) + b
4 = 5 + b
b = -1

Answer:
<4 = 81
Step-by-step explanation:
we know that all the interior angles of a triangle will equal 180
so <1 + <2 + <3 = 180
we know that <4 is the exterior angle to <3
the exterior angle is equal to the angles opposite to its interior
<3 is the interior angle to <4
<1 and <2 are the angles opposite to <3
so <4 = <1 + <2
<4 = 42 + 39
<4 = 81

I need help finding the slope, identifying the initial value and writing An equation for a linear function and finding the X answer Y intercept PLEASE HELP PLEASE
Answers
Answer/Step-by-step explanation:
✔️Slope (m) using the two points (2, 4.58) and (5, 4.28):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4.28 - 4.58}{5 - 2} = \frac{-0.3}{3} = -0.1 [/tex]
Slope (m) = -0.1
✔️Initial Value = y-intercept = b
To find b, substitute x = 2, y = 4.58, and m = -0.1 into y = mx + b.
(Note: y is P(t) and x is t).
Thus:
4.58 = (-0.1)(2) + b
4.58 = -0.2 + b
Add 0.2 to both sides
4.58 + 0.2 = b
4.78 = b
b = 4.78
Initial value = 4.78
✔️Equation for the linear function:
Substitute b = 4.78, and m = -0.1 into P(t) = mt + b
Thus the equation would be:
P(t) = -0.1t + 4.78
✔️The y-intercept = initial value = 4.78
✔️The x-intercept = the value of t when P(t) = 0.
To get this, substitute P(t) = 0 into P(t) = -0.1t + 4.78.
Thus:
0 = -0.1t + 4.78
Add 0.1t to each side
0.1t = 4.78
Divide both sides by 0.1
t = 47.8
x-intercept = 47.8

Ahmad and Dante wash cars in the neighborhood and charge $5 per car. Last year, they worked very hard and were able to wash 450 cars in the year. They have done a little market research and found that for every $0.20 that the price is reduced, they can get 50 more customers.
2. a. Model the relationship between the number of $0.20 price decreases and the amount of money earned using an equation, table, and graph.
Answers
The model for the relationship between the number of $0.20 price decrease, x, to the amount of money earned, E, is presented by the following equation;
E = -10•x² + 160•x + 2250Please find attached the values of the model in the attached table and graph of the model.
How can the equation of the model be found?Let x represent the number of $0.20 price decrease and let E represent the total amount earned (the revenue), we have the following revenue equation;
E = Amount earned = Number of cars washed × The price to wash one carHowever;
When the number of cars washed = (450 + 50•x)
The price to wash one car = (5 - 0.2•x)
Therefore;
E = (450 + 50•x) × (5 - 0.2•x)Which gives the following equation;
E = -10•x² + 160•x + 2250Please find the attached table and graph created using the above equation for the amount earned per year.
From the graph, the maximum amount is earned when the price is reduced by $0.20, eight times to give;
Optimum price = 5 - 0.2×8 = 3.4
The optimum price = $3.4The number of cars washed at the optimum price = 850The maximum amount earned = $2890Learn more about how to find the revenue function here:

step 1) 3•6 = 18
step 2) 3• -1i = -3i
Remember: if there is no coefficient, there is technically a 1 there so it’s easier to picture if you put that one in front of the variable.
step 3) 5i•6 = 30i
step 4) 5i• -1i= -5i^2
that turns into the expression 18-3i+30i-5i^2
then you can gather like terms (the -3i and 30i) 18+27i-5i^2
Remember that when you have and i that’s squared, it turns into -1.
So, the new expression is 18+27i-5(-1)
Remember to use order of operations and multiply first -5(-1)=5
18+27i+5
Then combine the constants (18 and 5)
The answer is: 23+27i

Rectangle WXYZ has coordinates at W(2, 2), X(2, 6), Y(4, 6), and Z(4, 2). If the rectangle was rotated 90° clockwise about the origin,
what would be the coordinates of X'?
Answers
The coordinates of X¹ will be (6,-2), if the rectangle was rotated 90° clockwise about the origin.
Given that, rectangle WXYZ has coordinates at W(2, 2), X(2, 6), Y(4, 6), and Z(4, 2) respectively. We have to calculate the coordinates of X¹ when the rectangle was rotated 90° clockwise about the origin.
Rotation generally helps us to align the figures in the direction along with a fixed point. To rotate the figure 90 degrees clockwise about a point, every point(x,y) will rotate to (y, -x). So, (y,-x) will be the rotation of the coordinates about 90° clockwise about the point.
So, we have to calculate the coordinate after rotation of X(2, 6). Let's suppose after rotation X changes to X¹ then, we have
X(2, 6)→X¹(6,-2) when the rectangle was rotated 90° clockwise about the origin.
Therefore, (6,-2) is the required answer.
