Owners of a recreation area are filling a small pond with water. They are adding water at a rate of 33 liters per minute. There are 500 liters in the pond to start.
Let W represent the total amount of water in the pond (in liters), and let T represent the total number of minutes that water has been added.
1. Write an equation relating W to T.
2. Then use this equation to find the total amount of water after 14 minutes.
Answers:
The equation is W = 33T + 500After 14 minutes, there are 962 liters of water.=======================================================
Explanation:
T = number of minutes33T = amount of added water in liters, since we're adding 33 liters per min.33T+500 = adding on the initial 500 litersThis leads to the equation W = 33T + 500
------------------------
Plug in T = 14
W = 33T + 500
W = 33*14 + 500
W = 462 + 500
W = 962 liters of water are in the pond after 14 minutes

The formula for the volume of a pyramid is uppercase V = one-third uppercase B h Which of the following equations is equivalent to the given formula?
Step-by-step explanation:
One possible equivalent equation to the given formula is:
uppercase B = 3 uppercase V ÷ h
To see why this equation is equivalent, we can isolate uppercase B in the original formula by multiplying both sides by 3/h:
3/h * uppercase V = 3/h * (one-third uppercase B h)
Simplifying the right-hand side:
3/h * (one-third uppercase B h) = uppercase B
Substituting back in the original formula gives:
uppercase B = 3/h * uppercase V

(a) The balance be at the end of the year is $502.53.
(b) The Effective annual interest rate is 0.5%.
(c) The Effective annual interest rate must be less than 6%.
What is effective annual interest rate?
The percentage of interest on a loan or financial product that would apply if compound interest built up over a year without any payments would be called the effective interest rate, also known as the effective annual interest rate, annual equivalent rate, or simply effective rate.
Given:
P = $500, n = 12, r = 0.5% = 0.005, t = 1
So, the balance be at the end of year is,
\(A = P(1+\frac{r}{n})^n^t \\A = 500(1+\frac{0.005}{12})^1^2^*^1 \\A = 500(1.00042)^1^2\\A = 502.53\)
Now to find the effective annual interest rate,
Effective annual interest rate = \(= (1+\frac{r}{n})^n-1 = (1+\frac{0.005}{12})^1^2 - 1= 0.005\)
Effective annual interest rate = 0.5%
So, the Effective annual interest rate must be less than 6%.
Hence,
(a) The balance be at the end of the year is $502.53.
(b) The Effective annual interest rate is 0.5%.
(c) The Effective annual interest rate must be less than 6%.

The increased availability of light materials with high strength has revolutionized the design and manufacture of golf clubs, particularly drivers. One measure of drivers that result in much longer tee shots is known as the coefficient of restitution of the club. An experiment was performed in which 15 drivers produced by a particular club maker were selected at random and their coefficients of restitution measured. It is of interest to determine if there is evidence to support a claim that the mean coefficient of restitution exceeds 0.82. Assume values to be normally distributed. The following observations were obtained for the 15 drivers:
0.8411 0.8191 0.8182 0.8125 0.8750
0.8580 0.8532 0.8483 0.8272 0.7983
0.8042 0.8730 0.8282 0.8359 0.8660
Conduct the test using a significance level of 0.05.
Answer:
WE reject the Null and conclude that the mean coefficient of restitution exceeds 0.82
Step-by-step explanation:
This is a one sample t test :
The hypothesis :
H0 : μ = 0.82
H0 : μ > 0.82
Given the sample data:
0.8411 0.8191 0.8182 0.8125 0.8750
0.8580 0.8532 0.8483 0.8272 0.7983
0.8042 0.8730 0.8282 0.8359 0.8660
Sample size, n = 15
Sample mean = ΣX / n = 0.837
Sample standard deviation, s = 0.0246 (from calculator)
The test statistic :
T = (xbar - μ) ÷ (s/√(n))
T = (0.837 - 0.82) ÷ (0.0246/√(15))
T = 2.676
The critical value at α = 0.05
df = n - 1 ; 15 - 1 = 14
Tcritical(0.05, 14) = 1.761
Reject H0 if Test statistic > Tcritical
Since, 2.676 > 1.761 ; WE reject the Null and conclude that the mean coefficient of restitution exceeds 0.82
Find the inversion point of the given point (4, 5) with respect to the circle x² + y² - 4x - 6y - 3 = 0. Also, show in the graph.
The inversion point of (4, 5) with respect to the circle x² + y² - 4x - 6y - 3 = 0 is (6, 7).
Finding the inversion pointTo find the inversion point of the given point (4, 5) with respect to the circle x² + y² - 4x - 6y - 3 = 0, we need to follow these steps:
Step 1: Write the equation of the given circle in standard form by completing the square for x and y: (x - 2)² + (y - 3)² = 16.
Step 2: Find the radius of the circle by taking the square root of the constant term: r = √16 = 4.
Step 3: Find the distance between the given point (4, 5) and the center of the circle (2, 3) using the distance formula: d = √[(4 - 2)² + (5 - 3)²] = √8.
Step 4: Use the formula for inversion point to find the coordinates of the inversion point (x', y'): (x', y') = (h + r²/d² * (x - h), k + r²/d² * (y - k)), where (h, k) is the center of the circle and r is the radius.
Plugging in the values, we get: (x', y') = (2 + 4²/8 * (4 - 2), 3 + 4²/8 * (5 - 3)) = (6, 7).
Therefore, the inversion point of the given point (4, 5) with respect to the circle x² + y² - 4x - 6y - 3 = 0 is (6, 7).

4 3/8 + 5 1/2= in fractions
Answer:
9 7/8
Step-by-step explanation:
1. 4 3/8 can be converted into the improper fraction 35/8, and 5 1/2 can be converted into 11/2.
2. Now that we have 35/8 + 11/2, we have to find a common denominator. Since 2 goes into 8 four times, we can turn 11/2 into 44/8 by multiplying the numerator and denominator (the top and the bottom numbers) by 4.
3. Now we have 35/8 + 44/8. At this point, the all we have to do is add the numerators (the top numbers). 35+44=79, so our answer is 79/8, which we can simplify to 9 7/8.

Leroy plans to purchase a car for $32,000.
According to his research, the car loses all
of its marketable value after 12 years. If the
car depreciates in a straight line form, what
are the intercepts of the depreciation
equation?
The intercepts of the car depreciation equation are (0, 32000) and (12, 0).
Describe Equation?Equations can also be written in different forms, such as standard form, slope-intercept form, and point-slope form, depending on the context and the specific problem being solved. Additionally, equations can be manipulated and solved using a variety of techniques, including algebraic manipulation, factoring, substitution, and graphing.
If the car depreciates in a straight line form, we can assume that its value decreases linearly over time. Let's use the point-slope form of a linear equation to find the depreciation equation:
y - y1 = m(x - x1)
where y is the value of the car, x is the number of years since it was purchased, m is the rate of depreciation per year, and (x1, y1) is a point on the line.
We know that the car is worth $32,000 when it is purchased (i.e., at x = 0), so we can use this as our point (x1, y1). We also know that the car has no marketable value after 12 years (i.e., at x = 12), so we can use this as another point on the line.
Using the two points, we have:
y - 32000 = m(x - 0)
y - 0 = m(x - 12)
Simplifying these equations, we get:
y = mx + 32000
y = mx
Setting the right-hand sides of these equations equal to each other, we get:
mx + 32000 = mx
Solving for x, we get:
32000 = mx
x = 32000/m
Since the car loses all of its marketable value after 12 years, we know that the value of the car is 0 at x = 12.
0 = m(12) + 32000
m = -2666.67
Now we can substitute m into our equation to get:
y = -2666.67x + 32000
To find the intercepts of the depreciation equation, we set y = 0 and solve for x:
0 = -2666.67x + 32000
2666.67x = 32000
x = 12
So one intercept is at x = 12, which we already knew. To find the other intercept, we set x = 0 and solve for y:
y = -2666.67(0) + 32000
y = 32000
Therefore, the intercepts of the depreciation equation are (0, 32000) and (12, 0).
