To answer this question we first, have to put the length of the rectangle in terms of x. We know that the total area is 150 ft², and that the area of a rectangle is given by:
\(A=\text{width}\cdot\text{length.}\)Solving the above equation for the length, and substituting width=x, and A=150, we get:
\(\text{length}=\frac{150}{x}\text{.}\)Now, the length of the interior rectangle is:
\(\frac{150}{x}-8,\)and the width of the interior triangle is:
\(x-4.\)Therefore, the area of the interior triangle is given by the following expression:
\((x-4)(\frac{150}{x}-8)\text{.}\)Now, to determine the domain, we know that the sides of the interior rectangle must fulfill the following inequalities:
\(\begin{gathered} x-4>0, \\ \frac{150}{x}-8>0. \end{gathered}\)Therefore,
\(\begin{gathered} x>4, \\ \frac{150}{x}>8, \\ 150>8x, \\ \frac{150}{8}>x\text{.} \end{gathered}\)Answer:
Area as a function of x
\((x-4)(\frac{150}{x}-8)\text{.}\)Domain:
\((4,\frac{75}{4})\text{.}\)what is continuous function

Gambling is an issue of great concern to those involved in college athletics. Because of this concern, the National Collegiate Athletic Association (NCAA) surveyed randomly selected student athletes concerning their gambling-related behaviors. Of the 5594 Division I male athletes in the survey, 3547 reported participation in some gambling behavior. This includes playing cards, betting on games of skill, buying lottery tickets, betting on sports, and similar activities. A report of this study cited a 1% margin of error. The confidence level was not stated in the report. Use what you have learned to find the confidence level, assuming that the NCAA took an SRS.
The confidence level in this report of survey of student atheletes concerning their gambling-related behaviors is equals to 87.88%.
The confidence interval when calculated with the two tails methods then it can be used to test the two tail hypothesis for the same parameter provided that the confidence level. We have, National Collegiate Athletic Association (NCAA) take a survey of randomly selected student athletes concerning their gambling-related behaviors.
repoted participation of students, x = 3547
Sample size,n = 5594
Margin of error, E = 1% = 0.01
The sample proportion is a number of successes divided by the sample size, p-cap = 3547/5594
= 0.6341
The margin of error is for a confidence interval for a proportion, which is determined by using the following formula is
\(CL = Zα/₂ \sqrt{ \frac{ \hat{p} \: (1- \hat{p})}{n} }\)
= Zα/₂√(1 - 0.6341)0.6341/5594
= 0.0064 Zα/₂
This margin of error also has to be equal to 1% or
0.0064 Zα/₂ = 0.01
=> Zα/₂ = 0.01/0.0064 ~ 1.55
The confidence level is the probability of obtaining this value or less extreme, determine the probability using z- table,
P(-1.55< Z < 1.55) = P(Z < 1.55) - P(Z < -1.55)
= 0.9394 - 0.0606 = 0.8788 = 87.8
Thus the confidence level is 87.88%.

Evaluate the integral by changing to spherical coordinates:
the final result of the double integral is `(4/3)*a. we have to Integrate the inner integral with respect to z.
what is inner integral ?
An inner integral is a mathematical term that refers to the integral function that is evaluated first in a double integral.
In the given question,
To solve this double integral, we will use the following steps:
Integrate the inner integral with respect to z.
Evaluate the result of the inner integral at upper and lower limits of z.
Substitute the result of the inner integral into the outer integral and integrate with respect to y.
Evaluate the result of the outer integral at the upper and lower limits of y.
Simplify the expression.
Now, let's apply these steps to solve the given double integral:
Integrate the inner integral with respect to z:
∫(x²*z + y²*z + z³) dz = x²/2*z² + y²/2*z² + z^4/4 + C
where C is the constant of integration.
Evaluate the result of the inner integral at the upper and lower limits of z:
(x²/2*(a²-x²-y²)¹⁵ + y²/2*(a²-x²-y²)¹⁵ + (a²-x²-y²)²/4)
- (x²/2*(-a²+x²+y²)¹⁵ + y²/2*(-a²+x²+y²)¹⁵ + (-a²+x²+y²)²/4)
Substitute the result of the inner integral into the outer integral and integrate with respect to y:
markdown
∫[(x²/2*(a²-x²-y²)¹⁵ + y²/2*(a²-x²-y²)¹⁵ + (a²-x²-y²)²/4)
- (x²/2*(-a²+x²+y²)¹⁵ + y²/2*(-a²+x²+y²)¹⁵ + (-a²+x²+y²)²/4)] dy
Evaluate the result of the outer integral at the upper and lower limits of y:
= ∫[(x²/2*(a²-x²-y²)¹⁵ + y²/2*(a²-x²-y²)¹⁵ + (a²-x²-y²)²/4)- (x²/2*(-a²+x²+y²)¹⁵ + y²/2*(-a²+x²+y²)¹⁵ + (-a²+x²+y²)²/4)] dy
from y = -sqrt(a²-x²) to y = sqrt(a²-x²)
= (2/3)*x²*(a²-x²)¹⁵ + (2/3)*(a²-x²)²⁵
- (2/3)*x²*(-a²+x²)¹⁵ + (2/3)*(-a²+x²)²⁵
Simplify the expression:
= (4/3)*a³ - (4/3)*a*x²
Therefore, the final result of the double integral is `(4/3)*a

Answer: (Answer in explanation)
Step-by-step explanation:
(12)B > 180
Her goal is to make more than 180 so if she wants to sell each book for $12 then so if she sells 14 books or above she would get more than $180.
So B could equal anything 16 and above but in my case I chose 24
(12)24 = 288 > 180
So write a equation like mine that equals a number that's greater than 180. Keep in mind each book sells for $12 each. Then solve for B which is how many books she has to sell to get the number greater than 180.

A snail crawled 7 miles in 8.4 hours. At this speed, how long would it take the snail to crawl 10 miles?
Answer: 12 hours
Step-by-step explanation:
Let's set the speed as "s".
Remember that distance = speed * time
So, plugging the numbers given...
7 = s * 8.4
Divide both sides by 8.4
s = 5/6
Now, plug this into the distance = speed * time, with the distance being 10. Set the time as "t"
10 = 5/6 * t
Divide both sides by 5/6
12 = t
So, it would take 12 hours for the snail to crawl 10 miles.

Answer:
Step-by-step explanation:
A) Find an equation for the line perpendicular to the tangent line to the curve y=x^3-4x+6 at the point (2,6)
-The equation is y=
b) What is the smallest slope on the curve? At what point on the curve does the curve have this slope?
-The smallest slope on the curve is
-The curve has the smallest slope at the point
c) Find equations for the tangent lines to the curve at the points where the slope of the curve is 8.
Answer:
f(x) = x³ - 4x + 6
f'(x) = 3x² - 4
a) f'(2) = 3(2²) - 4 = 12 - 4 = 8
6 = 8(2) + b
6 = 16 + b
b = -10
y = 8x - 10
b) 3x² - 4 = 0
3x² = 4, so x = ±2/√3 = ±(2/3)√3
= ±1.1547
f(-(2/3)√3) = 9.0792
f((2/3)√3) = 2.9208
c) 3x² - 4 = 8
3x² = 12
x² = 4, so x = ±2
f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6
6 = -2(8) + b
6 = -16 + b
b = 22
y = 8x + 22
f(2) = 6
y = 8x - 10
The equation perpendicular to the tangent is y = -1/8x + 25/4
-The smallest slope on the curve is 2.92
The curve has the smallest slope at the point (1.15, 2.92)
The equations at tangent points are y = 8x + 16 and y = 8x - 16
Finding the equation perpendicular to the tangentFrom the question, we have the following parameters that can be used in our computation:
y = x³ - 4x + 6
Differentiate
So, we have
f'(x) = 3x² - 4
The point is (2, 6)
So, we have
f'(2) = 3(2)² - 4
f'(2) = 8
The slope of the perpendicular line is
Slope = -1/8
So, we have
y = -1/8(x - 2) + 6
y = -1/8x + 25/4
The smallest slope on the curveWe have
f'(x) = 3x² - 4
Set to 0
3x² - 4 = 0
Solve for x
x = √[4/3]
x = 1.15
So, we have
Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6
Smallest slope = 2.92
So, the smallest slope is 2.92 at (1.15, 2.92)
The equation of the tangent lineHere, we set f'(x) to 8
3x² - 4 = 8
Solve for x
x = ±2
Calculate y at x = ±2
y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)
y = (2)³ - 4(2) + 6 = 6: (2, 0)
The equations at these points are
y = 8x + 16
y = 8x - 16

Solve the following quadratic equation using the quadratic formula. Separate multiple answers with a comma if necessary.
\(−yx^{2} +4y−6=0\)
Answer:
\( y^2 -4y +6=0\)
\( y =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}\)
Where \( a = 1, b= -4 ,c =6\)
And replacing we got:
\( y = \frac{-(-4) \pm \sqrt{4^2 -4(1)(6)}}{2*1}\)
And solving we got:
\( y = \frac{4 \pm \sqrt{-8}}{2} =2 \pm 2\sqrt{2} i\)
Where \( i =\sqrt{-1}\)
And the possible solutions are:
\( y_1=2 + 2\sqrt{2} i , y_2 = 2 - 2\sqrt{2} i \)
Step-by-step explanation:
For this case we use the equation given by the image and we have:
\( -y^2 +4y -6=0\)
We can rewrite the last expression like this if we multiply both sides of the equation by -1.
\( y^2 -4y +6=0\)
Now we can use the quadratic formula given by:
\( y =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}\)
Where \( a = 1, b= -4 ,c =6\)
And replacing we got:
\( y = \frac{-(-4) \pm \sqrt{4^2 -4(1)(6)}}{2*1}\)
And solving we got:
\( y = \frac{4 \pm \sqrt{-8}}{2} =2 \pm 2\sqrt{2} i\)
Where \( i =\sqrt{-1}\)
And the possible solutions are:
\( y_1=2 + 2\sqrt{2} i , y_2 = 2 - 2\sqrt{2} i \)
