Answer:
[tex]f^{-1}(x) = \sqrt[3]{\frac{x -4}{5}} +2[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 5(x - 2)^3 + 4[/tex]
Required
Determine the inverse
[tex]f(x) = 5(x - 2)^3 + 4[/tex]
Replace f(x) with y
[tex]y = 5(x - 2)^3 + 4[/tex]
Swap the positions of x and y
[tex]x = 5(y - 2)^3 + 4[/tex]
Make y the subject
[tex]x -4= 5(y - 2)^3[/tex]
Divide by 5
[tex]\frac{x -4}{5}= (y - 2)^3[/tex]
Take cube roots of both sides
[tex]\sqrt[3]{\frac{x -4}{5}}= y - 2[/tex]
Add 2 to both sides
[tex]\sqrt[3]{\frac{x -4}{5}} +2 = y[/tex]
[tex]y = \sqrt[3]{\frac{x -4}{5}} +2[/tex]
Replace y with [tex]f^{-1}(x)[/tex]
[tex]f^{-1}(x) = \sqrt[3]{\frac{x -4}{5}} +2[/tex]

What is the solution to the system of linear equations?
X = -2, y = 0
x= – 1, y = 2
x = 4, y = - 4
x = 2, y = 8
Answer:
x=-2 and y =0
Step-by-step explanation:
2x + 3y=-4
y=2x + 4
2x -y = -4
4y= 0
y = 0
2x -0=-4

Answer:9& 5
Step-by-step explanation:
I give brainalist and points for an answer and explanation
Answer:
option D
Step-by-step explanation:
diameter of two small circle i.e 14cm
radius of two small circle =7cm
area of the small circle =πr²
area of the small circle=22/7 x7²
area of the small circle=154cm²
Radius of bigger circle =14cmArea of bigger circle=πr²Area of bigger circle=22/7×14²
Area of bigger circle=616cm²
Area of shaded region =area of bigger circle -area of small circle +area of small circle
area of shaded region =616-154+154
area of shaded region=308cm²
i.e approximately 282.74cm²

Select all the choices below that show three lengths that could be the lengths of a triangle?
2 cm, 3 cm, 8 cm
2 cm, 5 cm, 6 cm
4 cm, 8 cm, 11 cm
10 in, 5 in, 13 in
Answer:
The last three,
2 cm, 5 cm, 6 cm
4 cm, 8 cm, 11 cm
10 in, 5 in, 13 in
As long as any two sides added together are long than the third side, it works as a triangle!
A recent survey was conducted to compare the cost of solar energy to the cost of gas or electric energy. Results of the survey revealed that the distribution of the amount of the monthly utility bill of a 3-bedroom house using gas or electric energy had a mean of $93 and a standard deviation of $11. Three solar homes reported monthly utility bills of $56, $54, and $51. Which of the following statements is true?
A. Homes using solar power always have lower utility bills than homes using only gas and electricity.
B. Homes using solar power may have lower utility bills than homes using only gas and electricity.
C. Homes using solar power may actually have higher utility bills than homes using only gas and electricity.
D. The utility bills for homes using solar power are about the same as those for homes using only gas and electricity.
Answer:
A. Homes using solar power always have lower utility bills than homes using only gas and electricity.
Step-by-step explanation:
Gas and Electricity
[tex]\bar x = 93[/tex]
[tex]\sigma = 11[/tex]
Solar
Bills: 56, 54 and 51
Required
Determine which of the statements is true
First, we calculate the mean of the given data
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{56 + 54 + 51}{3}[/tex]
[tex]\bar x = \frac{161}{3}[/tex]
[tex]\bar x = 53.67[/tex]
Then, the standard deviation
[tex]\sigma = \sqrt{\frac{\sum(x - x_i)^2}{n}}[/tex]
[tex]\sigma = \sqrt{\frac{(56 - 53.67)^2 + (54 - 53.67)^2 + (51 - 53.67)^2}{3}}[/tex]
[tex]\sigma = \sqrt{\frac{12.67}{3}}[/tex]
[tex]\sigma = \sqrt{4.223}[/tex]
[tex]\sigma = 2.05[/tex]
So, we have:
Gas or Electricity
[tex]\bar x = 93[/tex]
[tex]\sigma = 11[/tex]
Solar
[tex]\bar x = 53.67[/tex]
[tex]\sigma = 2.05[/tex]
By comparison.
The mean and standard deviation of homes using solar panel is less than home using gas and electricity.
This implies that: (a) is true.

70+95 Factor the expression using the GCF
giving brain
Answer:
70 + 95 = 5(14 + 19)
70 + 95 = 5(14 + 19)
gcf = 5
Step-by-step explanation:
70+95
70=2*5*7
95=5*19
70+95=(5*2*7)+(5*19)=(5*14)+(5*19)=5*(14+19)=5*(33)
5*33=165 and 70+95=165 Hope this helps! Please give me brainly!
Thelma and Louise ordered take - out from Belle Taco . Thelma ordered 2 tacos and 1 burrito and paid $ 3.79 . Louise ordered 2 burritos and 1 taco and paid . \$4.58
Answer:
A taco cost $1 while a burrito cost $1.79
Step-by-step explanation:
This may be computed as a set of simultaneous equations
Thelma ordered 2 tacos and 1 burrito and paid $ 3.79
let the cost of a taco be t and a burrito b then
2t + b = 3.79
Louise ordered 2 burritos and 1 taco and paid . \$4.58
t + 2b = 4.58
solve both equations simultaneously
multiply the first by 2
4t + 2b = 7.58
t + 2b = 4.58
subtract 2 from 1
3t = 3
t = 1
t + 2b = 4.58
1 + 2b = 4.58
2b = 4.58 - 1
2b = 3.58
Divide both sides by 2
b = 1.79
A taco cost $1 while a burrito cost $1.79
Solve. h+ 10.6 = -10.6 h= what
Answer:
h= -21.2
Step-by-step explanation:
Subtract 10.6 from both sides to isolate the h
h + 10.6 = -10.6 - 10.6 -10.6h= -21.2Now lets check the answer
-21.2 + 10.6 = -10.6
-10.6 = -10.6 ✅
