Answer:
The inverse of function [tex]f(x)= (x+7)^5[/tex] is [tex]\mathbf{f^{-1} (x)=\sqrt[5]{x}+7}[/tex]
Option A is correct option.
Step-by-step explanation:
For the function [tex]f(x)= (x+7)^5[/tex], Find [tex]f^{-1} (x)[/tex]
For finding inverse of x,
First let:
[tex]y=(x+7)^5[/tex]
Now replace x with y and y with x
[tex]x=(y+7)^5[/tex]
Now, solve for y
Taking 5th square root on both sides
[tex]\sqrt[5]{x}=\sqrt[5]{(y+7)^5}\\\sqrt[5]{x}=y+7\\=> y+7=\sqrt[5]{x}\\y=\sqrt[5]{x}-7[/tex]
Now, replace y with [tex]f^{-1} (x)[/tex]
[tex]f^{-1} (x)=\sqrt[5]{x}+7[/tex]
So, the inverse of function [tex]f(x)= (x+7)^5[/tex] is [tex]\mathbf{f^{-1} (x)=\sqrt[5]{x}+7}[/tex]

Answer:
[tex]27\frac{1}{4}[/tex]
Step-by-step explanation:
You can first add the whole numbers together-
16+5+5 = 16+10= 26
Next, we can find a common denominator for all the fractions
since one of the denominators is 3 and the other one is 4, we can multiply them to get 12.
Now, we can change all the denominators to 12 and multiply as needed
[tex]16 \frac{1}{3} = 16 \frac{4}{12}\[/tex]
[tex]5\frac{1}{4} =5\frac{3}{12}[/tex]
[tex]5\frac{2}{3} = 5\frac{8}{12}[/tex]
Finally, we can add up the fractions
[tex]\frac{4}{12}+ \frac{3}{12} +\frac{8}{12} = \frac{15}{12} = 1\frac{3}{12} = 1\frac{1}{4}[/tex]
Now we can add the whole number total with the fraction total
[tex]26+1\frac{1}{4}[/tex][tex]= 27\frac{1}{4}[/tex]
So, our answer is [tex]27\frac{1}{4}[/tex]

Find the slope of the given line, if it is defined.
The line through the origin and (-9,12)
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The slope equals
(Simplify your answer.)
B. The slope is undefined.
Answer:
The slope equals -⁴/3
Step-by-step explanation:
Slope of the line passing through the origin (0, 0) and (-9, 12):
Slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 0}{-9 - 0} = \frac{12}{-9} = -\frac{4}{3} [/tex]
Slope (m) = -⁴/3

Answer:
x=8
AC=148
Step-by-step explanation:
Okay so if B is the midpoint of AC, that basically means that it's the halfway point. If B is exactly halfway between A and C, that means that the distance between A and B, and the distance between B and C is the same. In other words: AB=BC
Knowing that AB=BC, we can sub the values given by the question:
AB = BC
9x+2 = 5x+34
9x-5x = 34-2
4x = 32
x = 8
Now that we know the value of x, we can find AC, since AC=AB+BC
AC = AB + BC
= 9x+2 + 5x+34
= 14x+36
= 14(8)+36
=112+36
=148

6) Solve the equation by Completing the Square. Show all the solutions.
x2 + 8x -5 = 0
Complete the equation of the line through (-6,5) and (-3,-3). Use exact numbers.
Answer:
y = - 8/3 x - 11
Step-by-step explanation:
We start by finding the slope of the segment thatjoins the two points using the slope formula:
slope = (y2 - y1) / (x2 - x1)
In our case:
slope = (-3 -5) / (-3 - -6) = -8/3
Now that we have the slope, we use the general expression for a line in slope-intercept form ( y = m x + b), requesting that one of the given points (for example point (-3, -3) )is part of the line as shown below:
y = m x + b
y = - 8/3 x + b
(-3) = - 8/3 (-3) + b
- 3 = 8 + b
b = - 11
Then the equation of the line is:
y = - 8/3 x - 11

Triangle ABC is congruent to triangle XYZ, as shown below.
Which of the following statements must be true?
(PLEASE HELP IF YOU CAN I WILL GIVE YOU 10 POINTS.)
Answer:
the first answer
Step-by-step explanation:
if a and x are the same and a has an angle of 45 degrees that means that x has an angle of 45 degrees
The required condition that must be true is,
(a) ∠x = 45°
(c) YZ = 3 cm
Incongruent geometry, the shapes that are so identical. can be superimposed to themselves.
Here,
For the given triangle to be congruent,
Each pair of corresponding angles and sides must be equal,
So,
(a) ∠x = 45°
When applying the cosine formula,
we get,
(c) YZ = 3 cm
Thus, the required condition that must be required to be to make the triangle congruent are,
(a) ∠x = 45°
(c) YZ = 3 cm

Estimating with percents: Isaac and his sister plan to surprise their parents by buying then each a pair of shoes. They agree that Isaac will pay 68% of the price since he receives a greater allowance. Use and estimation strategy to determine how much Isaac will pay if the total bill is $97.65. Show the step-by-step process you used to solve the problem
for estimating round both the price of shoes and the percentage to round numbers
97.65 is close to 100, so use 100 for the price of shoes
68% is close to 70 so use 70%
then multiply 100 by 70 %,
100 *70% = 70 dollars
so Isaac would pay around 70 dollars
Answer:
Issac has to pay 68% and 68% as a decimal is .68 So to solve this you would multiply 97.65 x .68 = 66.40 So Isaac will pay $66.40 dollars. If you want to go even further his family would pay 31.25$ of the total cost. Hope this helps you
Step-by-step explanation:
The engineer designed the valve such that it would produce a mean pressure of 5.0 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 6 engines and the mean pressure was 5.4 pounds/square inch with a standard deviation of 0.7. A level of significance of 0.025 will be used. Assume the population distribution is approximately normal. Make the decision to reject or fail to reject the null hypothesis.
Answer:
The calculated value t = 1.399 < 2.5705 at 0.025 level of significance
Null hypothesis is accepted
The population distribution is approximately normal
Step-by-step explanation:
Step(i):-
Given mean of the Population = 5.0
sample size 'n'= 6
The mean of the sample x=5.4 pounds /square inch
The standard deviation of the sample (S) = 0.7
Level of significance = 0.025
Null Hypothesis : The sample came from population
H₀ : x⁻ = μ
Alternative Hypothesis :H₁ : x⁻ ≠ μ
Step(ii):-
Test statistic
[tex]t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }[/tex]
[tex]t = \frac{5.4 -5.0}{\frac{0.7}{\sqrt{6} } }[/tex]
t = 1.399
Degrees of freedom = n-1 =6-1 =5
The tabulated value
t = 2.5705
The calculated value t = 1.399 < 2.5705 at 0.025 level of significance
Null hypothesis is accepted
The population distribution is approximately normal

Answer:
4. 50.19°
5. 25.19°
Step-by-step explanation:
4. Reference angle = x°
Opposite = 6 units
Adjacent = 5 units
Thus,
[tex] tan(x) = \frac{6}{5} [/tex]
[tex] tan(x) = 1.2 [/tex]
[tex] x = tan^{-1}(1.2) [/tex]
[tex] x = 50.19 [/tex] (nearest hundredth)
5. Reference angle = x°
Opposite = 48 - 5.2 = 42.8 ft
Adjacent = 91 ft
Thus,
[tex] tan(x) = \frac{42.8}{91} [/tex]
[tex] tan(x) = 0.47032967 [/tex]
[tex] x = tan^{-1}(0.47032967) [/tex]
[tex] x = 25.19 [/tex] (nearest hundredth)b
