f(x)=10 x-10 . Find each value.
(f ⁰ f⁻¹)(d)
Function composition exists a mathematical procedure where two functions, f and g, are taken and a function, h = g ⁰ f, exists produced such that h(x) = g(f(x)).
If the function be f(x) = 10x - 10 then the value of (f ⁰ f⁻¹)(d) is 99.
What is meant by composition?Function composition exists a mathematical procedure where two functions, f and g, exists taken and a function, h = g ⁰ f, exists produced such that h(x) = g(f(x)). The function g is used in this operation on the outcome of applying the function f to x.
Let the function be f(x) = 10x -10
We want to find (f ⁰ f⁻¹)(d)
To differentiate with respect to X, then we get
[tex]F^{-1}[/tex](x) = 10
To find the value of (f ⁰ f⁻¹)(d)
F([tex]f^{-1}[/tex](x)) = F(10)
F([tex]f^{-1}[/tex](x)) = 10x - 10
substituting the values in the above equation, then
F([tex]f^{-1}[/tex](x)) = 10(10) - 10
simplifying the above equation, we get
F([tex]f^{-1}[/tex](x)) = 100 -10
F([tex]f^{-1}[/tex](x)) = 99
Therefore, the value of (f ⁰ f⁻¹)(d) = 99

Jodi wants to visit her extended family in barbados next summer, and the flight costs $450. how much does she need to save each month if she wants to buy the flight in exactly 9 months?
If Jodi wants to visit her extended family in Barbados next summer, and the flight costs $450, then she needs to save 50$ each month if she wants to buy the flight in exactly 9 months.
If the flight costs $450, then the amount of money Jodi needs to save each month can be determined by using division.
Division is one of the four basic operations of arithmetic and involves the separation into equal parts.
By dividing the cost of the flight by the number of months, the money Jodi needs to save each month can be calculated.
Considering x to be money Jodi needs to save each month,
x = flight cost / number of months
x = 450 / 9
x = 50
Hence, the money Jodi needs to save each month if she wants to buy the flight in 9 months is calculated to 50$.

MODELING REAL LIFE Bowling alley A charges $3.75 to rent shoes and $4 per game. Bowling alley B charges $2.50 to

a. For what numbers of games is the total cost, including a pair of rental shoes, less at bowling alley A? at bowling alley B?
Bowling alley A:
Bowling alley B:
or more games
or
games
b. Bowling alley A increases the cost per game by $0.50. How does this affect your answer in part (a)? Explain.o
Using linear functions, it is found that:
a) The cheaper costs are given as follows:
Bowling alley A: 3 or more games.Bowling alley B: 1 or 2 games.b) Due to the same cost per game and higher cost for the pair of shoes, bowling alley A will never be cheaper than bowling alley B.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The cost to rent shoes is the intercept.The cost per game is the slope.Hence the cost functions are given as follows:
A(x) = 3.75 + 4x.B(x) = 2.5 + 4.5x.The costs are equal when:
A(x) = B(x)
3.75 + 4x = 2.5 + 4.5x
0.5x = 1.25
x = 1.25/0.5
x = 2.5.
Hence the cheaper costs are given as follows:
Bowling alley A: 3 or more games.Bowling alley B: 1 or 2 games.Alley B has the lower initial cost due to the lower cost for the pair of shoes.
For item b, if we increase the cost per game by $0.50 for alley A, we have that:
A(x) = 4.5x + 3.75.
Hence:
Due to the same cost per game and higher cost for the pair of shoes, bowling alley A will never be cheaper than bowling alley B.

What is defined as the acceleration?Acceleration is the rate during which velocity changes over time, both in terms of speed and direction. A point or takes place in a straight line is sped up if it quickens or decelerates. Even if the speed is constant, motion on such a circle is accelerated because the direction is constantly changing.For the given question;
Every horizontal block is 1/8 hour = 7.5 minutes long.
Each vertical block has a speed of 10 km/hr:
The table drawn as per the data given in the table:
Time Velocity km/hr
0 Min ( 0 hr) ---> 0
15 Min (1/4 hr) --> 50
45 Min (3/4 hr) --> 50
60 MIn ( 1 hr) --> 100
90 Min ( 3/2 hr) ---> 100
120 Min ( 2hr) ---> 0
The formula for acceleration:
Part a: Acceleration = final velocity - initial velocity / final time - initial time
Acceleration in the first 15 minutes: (1/4 hr) = (50 - 0)/(1/4 - 0)
= 50/(1/4)
=200
Thus, acceleration in the first 15 minutes is 200 kmph.
Part b: Distance among two cities:
= (1/2)(0 + 50)(1/4 - 0) + 50 * (3/4 - 1/4) + (1/2)(50 + 100)(1 - 3/4) + 100 * (3/2 - 1) + (1/2)(100 + 0)(2 - 3/2)
= 25/4 + 25 + 75/4 + 50 + 25
= 125
The difference distance for two cities is 125 kilometers.
Part c: Average speed = distance/2
Average Travel Speed = 125/2 = 62.5 km/hr
Therefore,
a: Acceleration in the first 15 minutes = 200 km/h²
b: The distance between two cities is 125 kilometers.

second : the law of sine
a/sin(A) = b/sin(B) = c/sin(C)
a, b, c are the sides, A, B, C are the the corresponding opposite angles.

Tristian says that 9.32 is a rational number Barry says that 9.32 is a terminating decimal who is correct
Tristian and Barry both are correct as 9,32 is a rational and terminating decimal.
A rational number is one that can be written as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.
A terminating decimal is a decimal number with a finite number of digits after the decimal point. The repeating decimal 5.6500000000... can be used to represent a terminating decimal like 5.65, however, when it is zero, the value is typically referred to as terminating.
A decimal number having a limited number of digits following the decimal point is referred to as a terminating decimal. Therefore, all decimal numbers that terminate are rational numbers.
Hence both are correct.
