The antiderivative function F(x) is verified.
The most general antiderivative of the function f(x) = x2 − 7x 3 is given below.
We know that the antiderivative of f(x) is a function F(x) such that F′(x) = f(x).So, integrating f(x), we get; ∫f(x)dx = ∫(x2 − 7x 3)dx = [ x3/3 − 7/4 x 4/4 ] + c, where c is the constant of the antiderivative.Therefore, the most general antiderivative of the function f(x) = x2 − 7x 3 is given by;
F(x) = x3/3 − 7/4 x 4/4 + c
To check the answer, let us differentiate the above antiderivative function F(x) and we will get back the given function f(x).Differentiating F(x) w.r.t x, we get;
F′(x) = (x3/3)' − (7/4 x 4/4)' + c' = x2 − 7x 3 + 0 = f(x)

What is probability?
Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1.
Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means.
You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a specific event will occur.
Step by Step Exlaination:
A spinner is divided into 8 parts.
Numbered as 9 to 16.
S={9,10,11,12,13,14,15,16}
n(S)=8.
A:probability of getting reater than 15.
A={16}
m(A)=1
p(A)=m(A)/n(S).
= 1/8.
=0.125
p(A)=0.125
Probability of getting greater than 15 is 0.125

if in a triangle ac= 15 and angle abc=60 degrees what is ab?
Answer:
∠A=30° and AC and BC is 13 and 7.5 units respectively
Step-by-step explanation:
Given that in a right triangle ABC , right angled at C , if angle B =60 degree and AB =15 units
we have to find the remaining angles.
By angle sum property, sum of angles in right angle is 180°
∠A+∠B+∠C=180°
∠A+ 60°+90°=180
∠A=180°-150°=30°
∠A=30°
As AB= 15
Now by trigonometric ratios we find the other sides of triangle ABC
Hence, ∠A=30° and AC and BC is 13 and 7.5 unitsStep-by-step explanation:

Which team had the best overall record for the season? Determine the best measure of center to compare, and explain your answer.
Eagles; they have a larger median value of 21 points
Falcons; they have a larger median value of 24 points
Eagles; they have a larger mean value of about 22 points
Falcons; they have a larger mean value of about 20.9 points
The team that has best overall record for the season is the falcons because they have a larger mean value of 20.9 points
How to find the mean of the given data?The mean of the dataset is defined the sum of all values divided by the total number of values. Therefore mean can be expressed as;
mean = sum of items/number of items
The mean value of Eagles = (3 + 24 + 14 + 27 + 10 + 13 + 10 + 21 + 24 + 17 + 27 + 7 + 40 + 37 + 55)/15
= 310/15 = 20.67
The mean value of falcons = (24 + 24 + 10 + 7 + 30 + 28 + 21 + 6 + 17 + 16 + 35 + 30 + 28 + 24 + 14)/15
= 314/15 = 20.93
Therefore since the mean value of falcons is higher than eagles, falcons has the best overall performance.

Angle ABC is bisected by line segment AD. If angle ABC measures 108° and one of the smaller angles created by line AD measures (5x+4), what is the value of x?
Answer:
x = 10
Step-by-step explanation:
One of the smaller angles that is created by the angle bisector measures 5x+4.
An angle bisector cuts an angle into two equal parts. So, 5x+4 = 1/2 (108) or
2(5x+4)=108 (divide both sides by 1/2)
10x+8=108 (distribute)
10x=100 (subtract 8 from both sides)
x=10 (divide by 10)

Find (g∘w)(x)and (w∘g)(x)for g(x)=7x−4 and w(x)=x2−7x+3(g∘w)(x)=(w∘g)(x)=
In order to calculate the composite function (gow)(x), that is, g(w(x)), we need to use w(x) as the input (value of x) in the function g(x).
So we have:
\(\begin{gathered} g(x)=7x-4 \\ g(w(x))=7w(x)-4 \\ g(w(x))=7(x^2-7x+3)-4 \\ g(w(x))=7x^2-49x+21-4 \\ g(w(x))=7x^2-49x+17 \end{gathered}\)Now, calculating (wog)(x), we have:
\(\begin{gathered} w(x)=x^2-7x+3 \\ w(g(x))=g(x)^2-7g(x)+3 \\ w(g(x))=(7x-4)^2-7\cdot(7x-4)+3 \\ w(g(x))=49x^2-56x+16-49x+28+3 \\ w(g(x))=49x^2-105x+47 \end{gathered}\)Charles measured three pieces of string.The strings measured 7.68 inches,3.9 inches,and 2.2 inches.What is the difference in length between the longest string and the shortest string
Answer:
5.48
Step-by-step explanation:
Given length of three strings:
\(\text{Length of first string}, L_1=7.68\ inches\\\text{Length of second string}, L_2=3.9\ inches\\\text{Length of third string}, L_3=2.2\ inches\)
To find:
The difference in length between the longest and the shortest string?
Solution:
First of all, let us compare the given three decimal numbers.
We check the number before decimal first of all.
We can see that the numbers are 7, 3, and 2.
7 being the largest \(L_1\) is the longest string.
2 being the smallest \(L_3\) is the shortest string.
So, the difference is:
\(L_1-L_3=7.68-2.2\\\Rightarrow \bold{L_1-L_3=5.48 }\)
So, the answer is 5.48.

12] Will's salary is three times Nathan's salary. Together they earn $192 per week. Find the salary of each boy.
Nathan's salary is $48 and Will's salary which three times of Nathan's salary is $144.
What is salary?
An employment contract may include a salary clause as a type of recurring payment from an employer to an employee. In contrast, piece wages are paid separately for each job, hour, or other unit rather than on a regular schedule. Salary can also be seen from the perspective of operating a corporation as the expense of obtaining and keeping employees to carry out operations; this is known as a personnel expense or salary expense. Payroll accounts are used in accounting to record salaries.
It is given in the question that Will's salary is three times Nathan's salary.
So, lets assume that Nathan's salary is X it implies that Will's salary will be 3 times X = 3X
Together they earn $ 192.
So,
X + 3X = 192
4X = 192
X = 192/4
X = 48
Therefore, Nathan's Salary is $48
Since, Will's salary is 3 times of Nathan's salary,
So,
Will's salary = 3 (48) = 144
Therefore, Will's Salary is $144

What is an equation of the line that passes through the point (-6,-1)(−6,−1) and is perpendicular to the line 6x-y=76x−y=7?
The linear equation perpendicular to 6x-y=7 and that passes through (-6, -1) is:
y = (-1/6)*x - 2
How to get the equation for the line?A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
Two linear equations are perpendicular if the product between the slopes is equal to -1.
We want to find a line perpendicular to:
6x - y = 7
y = 6x - 7
Where the slope is 6.
Then:
a*6 = -1
a = -1/6
Then our line is something like:
y = (-1/6)*x + b
To find the value of b, we use the fact that our line passes through (-6, -1), then:
-1 = (-1/6)*-6 + b
-1 = 1 + b
-1 - 1 =b
-2 =b
The line is y = (-1/6)*x - 2

Area of his yard = 19680ft²
Fertilizer needed = 590.4 ounces
Step-by-step explanation:
Step 1 Find the area of his lawn
The question states that his lawn is a rectangle that measures 240 feet by 82 feet
To find the area of a rectangle we simply multiply the side lengths
Hence, area of his yard = 240 * 82 = 19680ft²
Step 2 find amount of fertilizer needed.
The question states that .03 ounces is used per square foot.
So to find the amount of fertilizer needed simply multiply total area by amount used per square foot.
19680 * .03 = 590.4
So we can conclude that John will need 590.4 ounces of fertilizer
