find f^-1(f(x)) for f(x)=(x-3)/2
After solving the given equation for f(x) the resultant answer is f(x)=1.
What are equations?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation. As in 3x + 5 Equals 15, for instance. Equations come in a variety of forms, including linear, quadratic, cubic, and others. The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.So, find f(x):
When f^-1(f(x)) in f(x)=(x-3)/2.Now, calculate as follows:
f(x)=(x-3)/2f(x)=(f⁻¹-3)/2f(x)=(1/f - 3)/2f(x)=(1 -3f/f)/2f(x)=(1-3)/2f(x)=2/2f(x) = 1Therefore, after solving the given equation for f(x) the resultant answer is f(x)=1.

Leann determines the volume of the cylinder shown using the formula V=Bh.
We have that the base of the cylinder is a circle, and the area of a circle can be calculated with the following equation:
[tex]B=\pi\cdot r^2[/tex]In this case, we have the following:
[tex]\begin{gathered} \pi=3.14 \\ r=\frac{d}{2}=\frac{6}{2}=3 \\ \Rightarrow B=(3.14)(3)^2=(3.14)(3)(3) \end{gathered}[/tex]therefore, the area of the base is B=(3.14)(3)(3) = 28.26 cm^2
Art club has 12 members. Each member paysmonthly dues of $12.60. On the first day of themonth, 4 members paid their dues. The remainingmembers paid their dues on the second day of themonth. How much money was collected in dues onthe second day of the month?
Given:
Total number of members in a club is 12
Each member pays $12.60 on every month.
[tex]\begin{gathered} \text{Number of members paid the dues on second day=12-4} \\ \text{Number of members paid the dues on second day=}8 \end{gathered}[/tex][tex]\begin{gathered} \text{Money collected on the second day=8}\times12.60 \\ \text{Money collected on the second day= \$100.80} \end{gathered}[/tex]Money collected on the second day of the month is $100.80
Answer:
100.8
Step-by-step explanation:
12-4 = 8
the 4 is the people who payes the first day the 8 is the people who payes the second day
12.60 eight times = 12.60•8= 100.8
the eight people each payes 12.60 so that would be 12.60 8 times
A line segment, ST, has endpoints S(-7,-3) and T(-1,-1). Which of the following equations represents the perpendicular bisector of the line segment? A. y = 2x - 15 B. y = -3x - 14 C. y = 6x - 14 D. y = -3x - 20
SOLUTION
The given points are: (-7,-3) and (-1,-1)
The slope of the line segment is:
[tex]\begin{gathered} m=\frac{-1-(-3)}{-1-(-7)} \\ m=\frac{-1+3}{-1+7} \\ m=\frac{2}{6} \\ m=\frac{1}{3} \end{gathered}[/tex]Recall that the product if solpes of perpendicular line give -1.
The the slope of the perpendicula bisector is:
[tex]\begin{gathered} m_1=\frac{1}{\frac{1}{3}} \\ m=3 \end{gathered}[/tex]Therefore the slope of the perpendicular bisector is -3.
Recall that the perpendicular bisector passes through the center of a line segment.
Hence the perpendicular bisector will pass through:
[tex]\begin{gathered} (\frac{-7-1}{2},\frac{-3-1}{2}) \\ =(\frac{-8}{2},\frac{-4}{2}) \\ =(-4,-2) \end{gathered}[/tex]Using the point slope form, the equation of the perpendicular bisector is:
[tex]\begin{gathered} y-(-2)=-3(x-(-4)) \\ y+2=-3x-12 \\ y=-3x-12-2 \\ y=-3x-14 \end{gathered}[/tex]Therefore the required equation is:

Given:
Mikaela has been tracking her basketball stats for the last week.
We need to write a linear equation with the variable t for time
Let the equation has the form: y = m * t + b
Where y is the number of baskets she has made
She started shooting hoops today having already made 3200 baskets this
week.
so, at t = 0 , y = 3200
so, the value of b = 3200
We will find the value of m using the given table:
start 3200
10 min 3225
20 min 3250
30 min 3275
40 min 3300
So, the value of m = (3250 - 3225)/(20 - 10) = 25/10 = 2.5
So, the equation will be:
[tex]y=2.5t+3200[/tex]Now, we will find how many baskets will she have made if
she continues for one hour today?
So, we will substitute with t = 60 min into the last equation
So,
[tex]y=2.5\cdot60+3200=3350[/tex]So, she will make 3350 baskets

4. A number between 200 and 400 with 6 more tens than ones.
Answer
Question 3
Largest number where the sum of the digits is 16 is 862
Question 4
The number between 200 band 400 with 6 more tens than ones is 382
Explanation
We can only use numbers from the digit bank to answer this questions.
Question 3
Largest number where the sum of the digits is 16 is 862
Question 4
A number between 200 and 400 with 6 more tens than ones.
Noting that the tens digit is the second digit from the right in a number and the ones digit is the first number from the right for any number.
So, we are asked to form a number whose second number from the right is 6 more than the first number from the right.
So, we can easily see that
The ones number has to be 2
The tens number has to be 8 (Since 8 is 6 more than 2)
Then, for the third and last number, since the number has to be between 200 and 400, the last number has to be 3.
So, the number between 200 band 400 with 6 more tens than ones is 382

Answer:
Step-by-step explanation:
1.
circumference of circular fence = 2πr
π = 3.14
r = radius
radius of circular fence, r= 10 feet
putting the values in the formula,
circumference = 2× 3.14 × 10
= 62.8 feet
therefore the fencing brad need will be 62.8 feet
2.
Area of the circular hot tub = πr²
π= 3.14
r = radius
as given in the question,
diameter = 80 inches
we know diameter is equal to half radius so r = 40 inches
putting the values in the formula,
area = 3.14 × 40× 40
= 5,024 inches
hence the area of the hot tub is equal to 5,025 inches
3.
Area of the circular wall clock = πr²
π= 3.14
r = radius
as per the question ,
area of 5 inches wall clock = 3.14× 5×5 = 78.5 inches
and area of 6 inches wall clock = 3.14 ×6×6 = 113.04 inches
To find the how much wall space will 6 inches wall clock takes we have to subtract both areas,
area of 6 inches wall clock - area of 5 inches wall clock = 113.04 - 78.5
= 34.54 inches
6 inches wall clock will take 34.54 inches of area more.
4.
In one rotation tire will cover whole area so to find the diameter we have to put area of circle equals to area of tire
Area of the circle = πr²
π= 3.14
r = radius
as per the question ,
area of the tire =116.18 inches
πr² = 116.18
r=6.08 inches
diameter = 2 × r= 12.16 inches

Find the prime factorization of the following number write any repeated racists using exponents
Prime factorization refers to the process of decomposing a given number into a product of prime numbers that can be repeated or not.
Let's remember that prime numbers are numbers that can only be divided by 1 or itself.v Having this in mind we have that the prime factorization of 66 is:
[tex]66=(2)(3)(11)[/tex]For any right triangle, the side lengths of the triangle can be put in the equation a^2+ b^2 = c^2 where a, b, and c are the side lengths. A triangle with the side lengths 3 inches, 4 inches, and 5 inches is a right triangle. Which way(s) can you substitute the values into the equation to make it true? Which variable has to match the longest side length? Why?
It is given that the side lengths of any right triangle can be put in the equation:
[tex]a^2+b^2=c^2[/tex]For a triangle with the side lengths 3 inches, 4 inches, and 5 inches, it can be substituted in two ways that will make the equation true:
Let a=3, b=4, and c=5:
[tex]\begin{gathered} 3^2+4^2=5^2 \\ \Rightarrow9+16=25 \\ \Rightarrow25=25 \end{gathered}[/tex]Hence, the equation is true.
You can also substitute a=4, b=3, and c=5.
This will also give the same result.
Notice that variable c has to match the longest side length.
The reason for this is that equality can only hold if the longest side is the variable at the right, if not there'll be an inequality instead.
