Based on the distance between the park bench and the basketball court, the distance between the park bench and the pond is 57¹/₈ feet
What is the distance between the park bench and pond?The distance between the park bench and the basketball is the sum of the distance between the park bench and the pond and the pond and the basketball court.
The distance between the park bench and the pond is therefore:
= Distance between park bench and basketball court - Distance between pond and basketball court
Solving gives:
= 75³/₄ - 18⁵/₈
= 75.75 - 18.625
= 57.125
= 57¹/₈ feet

Estimate the instantaneous rate of change of the function f(x)=−4x2−3x+1 at x=−3 using the average rate of change over successively smaller intervals.
Answers
The instantaneous rate of change of the function f(x) = −4x² − 3x + 1 at the point x = -3 is 21.
What is the instantaneous rate of change of the function at the given point?The instantaneous rate of change is simply the change in the derivative value at a specific point.
Given the data in the question;
f(x) = −4x² − 3x + 1Point x = -3To determine the instantaneous rate of change of the function, first find the derivative of the function.
f(x) = −4x² − 3x + 1
Applying sum rule, with respect to x
d/dx[ -4x² ] + d/dx[ -3x ] + d/dx[ 1 ]
[ 2 × -4x¹ ] + [ 1 × -3x⁰ ] + d/dx[ 1 ]
[ -8x ] + [ -3 ] + d/dx[ 1 ]
-8x - 3 + d/dx[ 1 ]
Differentiate using constant rule
-8x - 3 + [ 0 ]
-8x - 3
f'(x) = -8x - 3
Next, plug x = -3 into the derivative and simplify.
f'(x) = -8x - 3
f'(-3) = -8(-3) - 3
f'(-3) = 24 - 3
f'(-3) = 21
Therefore, the instantaneous rate of change of the function f(x) = −4x² − 3x + 1 at the point x = -3 is 21.

In two or more complete sentences, explain how to use ordered pairs of points in f(x)=2x+5 and g(x)= x-5/2 to determine if f(x) and g(x) are inverses of each other.
Answers
The ordered pair given are not inverse to each other because:
Substituting a value say 5/2 into f(x)=2x+5 gives 10Substituting 10 into g(x)= x-5/2 does not return 5/2How to know inverse functionsWhen two functions are inverse to each other substituting a value A in function say AA will give answer say X, substituting the answer X to the the other function say BB returns the value A.
Instance
say function AA, plug in A gives X
the inverse will be:
say function BB plug in X gives A
So, we have f(x)=2x+5 and g(x)= x-5/2
plugging in say 5/2 in f(x) will give
f(x) = 2 * 5/2 + 5
f(x) = 5 + 5
f(x) = 10
We plug in 10 to g(x)= x-5/2
g(x) = 10 - 5/2
g(x)= 7/2
since 7/2 ≠ 5/2 the pair of functions are not inverse to each other

What is defined as the concept of work and time?Work is described as anything that has an impact or has an outcome. When it is stated somebody has done a certain work, it means that he or she has completed all of the work. As a result, if Manu accomplishes his work in 5 days, he will complete 100% of the work in 5 days.As a result, we could indeed say that he completes 20% of a work in one day. Similarly, he completes 40% of a work in two days and 60% of a work in three days.For the given question;
Rob takes 6 hours for cleaning the ware house.
Let 'R' be the work done by rob.
Then, work done by Rob in 6 hours is 1/R = 1/6.
Similarly;
Let work by Molly is 'R'.
The, work done by Molly in 1 hour is 1/M = 1/9.
The total work done by both is 1 hour is;
1/R + 1/M = 1/6 + 1/9

d = 80mph - 65mph
Evaluate
d = 15mph
The distance moved is
Distance = 15 * t
At 580 miles apart, we have

Answers
Brett will get paid $55.68 for travelling a total of 87 kilometers at an allowance of 54 cents per kilometer.
According to the International System of Units (SI), one kilometer is equal to 1,000 meters in American English. The United States and the United Kingdom are significant outliers, where the statute mile is the unit of measurement used to express distances between geographical locations on land.
One Kilometer is roughly equivalent to 0.621 miles.
Brett delivers produce for the farmer using his truck.
He gets paid a travel allowance of 64 cents per kilometer.
So to calculate his total allowance we multiply the allowance with the distance travelled.
Brett gets paid: $0.64×87=$55.68

Find the standard deviation of this data set using the table method that is in the Course Notes, please show your work. You can think of the class of 7 students as a population.
Answers
For the given set of data, the value of mean is 83, median is 87 and standard deviation is 11.03
What is standard deviation?Standard deviation is a measurement of how evenly distributed a set of numbers is. Since the variance is the average of the squared deviations from the mean, it is the square root of the variance.
The mean score is - Sum of all scores / total number of scores
= 89 + 72 + 96 + 87 + 64 + 93 + 80 / 7
= 83
So the mean of given scores is 83
Median = central term
= 64, 72, 80, 87, 89, 93, 96
Median = 87
Mode of the data is - no mode as there are no recurring terms given
Standard deviation -
variance = (89 - 83)² +(72 - 83)² + (96 - 83)² + (87 - 83)² + (64 - 83)² + (93 - 83)² + (80 - 83)² / 7
= 121.71

What is the conditional probability of getting an A on the third exam given that they got an A on the first exam, P(A third | A first)?So, according the question,
Let's assume, total no. of students in class is x.
So, we know that
Conditional probability P( A IIIrd | A Ist ) = [tex]\frac{P(III^{rd} \cap I^{st}) }{P(I^{st})}[/tex]
From question,
P( A IIIrd ∩ A Ist) = 12/x. and

Now, putting the values
So, we will get
P( IIIrd | Ist ) = [tex]\frac{P(III^{rd} \cap I^{st}) }{P(I^{st})}[/tex]
P( IIIrd | Ist ) = [tex]{(\frac{12}{x})}\div {(\frac{27}{x} )}[/tex]

First make a substitution, and then use integration by parts to evaluate the integral.
Answers
Answer: 1/2 ([tex]\pi[/tex]) sin [tex]\pi[/tex] + ∫ x cos [tex]\pi ^{2}[/tex] dx + c
1/2 ([tex]\frac{\pi }{2}[/tex]) sin [tex]\frac{\pi }{2}[/tex] + ∫ x cos [tex]\frac{\pi }{2} ^{2}[/tex] dx + c
Step-by-step explanation:
We can't just integrate straight away, so we try substitution.
While trying substitution, we observe that we could integrate cos([tex]x^{2}[/tex]) x dx
by substitution.
So, let's split the integrand and use integration by parts.
we can represent θ = x,
so, we can write,
= ∫[tex]x^{3} cos x^{2} dx[/tex]
= ∫ [tex]x^{2} cos (x^{2} )xdx[/tex]
We notice that we could rewrite this as ∫ u cos(u) 1/2 du, but we don't see how to integrate that, so we'll continue with parts for now.)
= ∫ [tex]x^{2} cos (x^{2} )xdx[/tex]
Let u=[tex]x^{2}[/tex] and dv = [tex]cos(x^{2} )xdx[/tex]
Clearly du= 2x dx, and
we can integrate dv by substitution to get.
= 1/2 sin [tex]x^{2}[/tex]
uv - ∫ vdu = 1/2 [tex]x^{2}[/tex] sin([tex]x^{2}[/tex]) - ∫ x sin ([tex]x^{2}[/tex]) dx
Integrate by substitution again to finish.
∫ [tex]x^{3} cos (x^{2}) dx[/tex] = 1/2 [tex]x^{2} sin x^{2}[/tex] + ∫ x cos [tex]x^{2}[/tex] dx + c
Then,
x = √[tex]\pi[/tex] and √[tex]\frac{\pi }{2}[/tex]
∫ [tex]x^{3}[/tex] cos [tex]x^{2}[/tex] dx = 1/2 (√[tex]\pi ^{2}[/tex]) sin √[tex]\pi ^{2}[/tex] + ∫ x cos [tex]\pi ^{2}[/tex] dx + c
= 1/2 ([tex]\pi[/tex]) sin [tex]\pi[/tex] + ∫ x cos [tex]\pi ^{2}[/tex] dx + c
∫ [tex]x^{3}[/tex] cos [tex]x^{2}[/tex] dx = 1/2 ([tex]\frac{\pi }{2}[/tex]) sin [tex]\frac{\pi }{2}[/tex] + ∫ x cos [tex]\frac{\pi }{2} ^{2}[/tex] dx + c

This implies:
x¹ = 4y¹ = 7x² = 6y² = 9You just need to enter it into the formula:
m = 9-7/6-4m = 2/2m = 1Now that we know both slopes, you can see that g(x) has a slope of 1, while f(x) has a slope of 4, indicating that f(x) has a steeper slope than g(x).

We have to calculate number of metal benches.
Let the number metal benches be x.
The according to the question
W = x - 27 where, W = wooden benches
Here , W = 24
Putting the required in the above equation for x we get
24 = x - 27
x = 24 + 27
