Answer: depth = 5 ft
width = 10 ft
length = 40 ft
Step-by-step explanation:
d = depth
width = d + 5
length = d + 36
Volume = length x width x depth = 2000 cf
d(d+35)(d+5) = 2000
d(\(d^{2}\) + 40d + 175) = 2000
d^3 + 40d^2 + 175d = 2000
rewrite in standard cubic polynomial form : ax3 + bx2 + cx + d = 0
d^3 + 40(d^2) + 175d - 2000 = 0
Find the roots of the cubic polynomial:
factors of 2000 are 1, 5, 10 15, 20, etc.
Try the factor 5 first by plugging it in the equation:
5^3 + 40(5^2) + 175(5) - 2000 = 0
Lucky break! No need to find the other roots because they will be negative, and you can't have a negative value for a pool depth.
So, depth = 5 ft
width = 5 + 5 = 10 ft
length = 5 + 35 = 40 ft

Which of the following is represents an estimate of Só edx using rectangles with heights given by right- hand endpoints and four subintervals (i.e. n 4)? Select one: o So e*dx is approximately (0.5)e0.5 + (0.5) + (0.5)1.5 + (0.5)e? o lo e* dx is approximately (0.5) + (0.5)e0.5 + (0.5) + (0.5) 1.5 o e*dx is approximately (0.5)e0.5 + (1)e! + (1.5)e1.5 + (2)e2 o fe*dx is approximately 2e2
The estimate of ∫e^x dx using rectangles with heights given by right-hand endpoints and four subintervals (n = 4) can be determined by evaluating the function at those endpoints and multiplying by the width of each rectangle.
Among the given options, the correct representation of the estimate is:
∫e^x dx is approximately (0.5)e^0.5 + (0.5)e^1 + (0.5)e^1.5 + (0.5)e^2.
This is because we divide the interval [0,2] into four subintervals of equal width, each with a width of 0.5. For the right-hand endpoint approximation, we evaluate the function e^x at those endpoints.
The height of each rectangle is given by e^x evaluated at the right-hand endpoint of each subinterval. The width of each rectangle is 0.5.
By multiplying the height and width of each rectangle and summing them up, we obtain the estimate of the integral.
Therefore, the correct representation is (0.5)e^0.5 + (0.5)e^1 + (0.5)e^1.5 + (0.5)e^2 as an estimate of ∫e^x dx using rectangles with right-hand endpoints and four subintervals.

Solve the simultaneous equations.
4x + 5y = 17
2x + 4y = 13
Answer:
x = 1/2 and y = 3
Step-by-step explanation:
Let
4x + 5y = 17 ......(i)
2x + 4y = 13 .....(ii)
Multiply equation (ii) by 2 to make like 'x' terms. Thus, the new equations are:
4x + 5y = 17 ......(i)
4x + 8y = 26 .....(ii)
Subtract equation (i) from (ii)
4x + 8y - (4x + 5y) = 26 - 17
4x + 8y - 4x - 5y = 9
3y = 9
y = 3
To find x, substitute value of y into any equation
4x + 5y = 17
4x + 5*3 = 17
4x + 15 = 17
4x = 17 - 15
4x = 2
x = 2/4
x = 1/2

Solve. x/4 + ½ = 1/8
x = ____ (Simplify your answer.)
Answer:
\( \frac{x}{4} + \frac{1}{2} = \frac{1}{8} \)
\( \frac{x}{4} = - \frac{3}{8} \)
\(x = - \frac{3}{2} = - 1 \frac{1}{2} \)
The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.
Consider the equation, we have only one x term, so taking all the terms without x to the other side and terms with x on one side.
x/4 + 1/2 = 1/8
Take the 1/2 term on the other side,
x/4=1/8 - 1/2
Taking the LCM on the Right side,
x/4 = (1-4) / 8
x/4 = -3/8
Now, we have x/4 so what we can do is, shift the 4 to the other side too, we get,
x = ( -3/8) * 4
x = -3/2
The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

What value must b have in the function f(x)=x^4+bx^2+1 so that the function has at least one inflection point over the interval (1,2)?
The function f(x) = x^4 + bx^2 + 1 has an inflection point at x = 0,
What is the inflection point?
An inflection point of a function is a point on the graph of the function where the concavity (curvature) of the graph changes. In other words, an inflection point is a point where the curve switches from being concave up to concave down, or vice versa.
The function f(x) = x^4 + bx^2 + 1 has an inflection point at x = 0, because the concavity of the graph changes at that point. To find the value of b such that the function has at least one inflection point over the interval (1,2), we can set x = 1 and x = 2 in the function and solve for b.
If we set x = 1, we get the equation f(1) = 1 + b + 1 = 0. Solving for b, we find that b = -2.
If we set x = 2, we get the equation f(2) = 16 + 2b + 1 = 0. Solving for b, we find that b = -9.
Since the function has an inflection point at x = 0 for any value of b, it will have at least one inflection point over the interval (1,2) for any value of b.
Therefore, the value of b can be any real number.

The zoo is building a new polar bear exhibit, and wants to put a semi-circular window in the concrete wall of the swimming tank. If the semi-circle has diameter 70 centimeters, and the bottom of the window is at a depth of 2.5 meters, find the hydrostatic force on the window.
The hydrostatic force on the window is approximately 47,481 Newtons.
We can use the formula for hydrostatic force, which is:
F = ρghA
where F is the hydrostatic force, ρ is the density of the fluid (water in this case), g is the acceleration due to gravity, h is the depth of the window, and A is the area of the window.
First, we need to find the area of the window. Since the window is a semi-circle with diameter 70 centimeters, the radius is 35 centimeters, and the area is:
A = (π/2)r^2
= (π/2)(35 cm)^2
= 1225π/2 cm^2
Next, we need to convert the depth of the window to meters:
h = 2.5 m
We also need the density of water, which is approximately:
ρ = 1000 kg/m^3
Finally, we need the acceleration due to gravity, which we can assume is:
g = 9.8 m/s^2
Now we can plug these values into the formula:
F = ρghA
= (1000 kg/m^3)(9.8 m/s^2)(2.5 m)(1225π/2 cm^2)
≈ 47,481 N
Therefore, the hydrostatic force on the window is approximately 47,481 Newtons.

If the two legs of a right triangle are 15 and 20, how long is the hypotenuse?
Answer:
25
Step-by-step explanation:
To solve this problem, you can use the pythagorean theorem, which is a^2 + b^2 = c^2 where a and b are legs and c is the hypotenuse. We can plug in the values of 15 and 20, and solve for c:
15^2 + 20^2 = c^2
225 + 400 = c^2
625 = c^2
c = 25
This means the hypotenuse is 25.

88 feet/second = 60 miles/hour. How many feet per second is 1 mile? (Hint: divide both side of the equation by the same amount.)
Answer:
1 mile/hour is equivalent to 1.47 feet/seconds
Step-by-step explanation:
Given
\(88 ft/s= 60 miles/hr\)
Required
Determine the equivalent of 1 mile/hour
\(88\ ft/s= 60\ miles/hr\)
Express 60 as 60 * 1
\(88\ ft/s= 60 * 1\ mile/hr\)
Divide both sides by 60
\(\frac{88\ ft/s}{60}= \frac{60 * 1\ mile/hr}{60}\)
\(\frac{88\ ft/s}{60}= 1\ mile/hr\)
Reorder
\(1\ mile/hr = \frac{88\ ft/s}{60}\)
Divide 88 by 60
\(1\ mile/hr = 1.46666666667\ ft/s\)
Approximate to 3 significant figures
\(1\ mile/hr = 1.47\ ft/s\)

The endpoints of GH are G(10,1) and H(3,5). What is the midpoint of GH?
Answer:
The answer is (6.5,3)
Step-by-step explanation:
The solution is in the image
The endpoints of GH are G(10,1) and H(3,5), then, the midpoint of GH is M(6.5, 3).
Here, we have to find the midpoint of line segment GH, we can use the midpoint formula.
The midpoint formula states that the coordinates of the midpoint (M) of a line segment with endpoints (x₁, y₁) and (x₂, y₂) are given by:
M(x, y) = \(((x_1 + x_2) / 2, (y_1 + y_2) / 2)\)
Then the midpoint will be
x = (x₁ + x₂) / 2
y = (y₁ + y₂) / 2
In this case, the endpoints of GH are G(10, 1) and H(3, 5).
Let's use the midpoint formula to find the midpoint (M) of GH:
x-coordinate of M = (x-coordinate of G + x-coordinate of H) / 2
x-coordinate of M = (10 + 3) / 2
x-coordinate of M = 13 / 2
x-coordinate of M = 6.5
y-coordinate of M = (y-coordinate of G + y-coordinate of H) / 2
y-coordinate of M = (1 + 5) / 2
y-coordinate of M = 6 / 2
y-coordinate of M = 3
So, the midpoint of GH is M(6.5, 3).
