find the inverse of the function
If h⁻¹(x) is the inverse of h(x), then by definition of inverse function,
h(h⁻¹(x)) = x
Given that h(x) = 6∛(2x + 5) - 1, we have
h(h⁻¹(x)) = 6∛(2 h⁻¹(x) + 5) - 1 = x
Solve for h⁻¹(x) :
6∛(2 h⁻¹(x) + 5) - 1 = x
6∛(2 h⁻¹(x) + 5) = x + 1
∛(2 h⁻¹(x) + 5) = (x + 1)/6
[∛(2 h⁻¹(x) + 5)]³ = [(x + 1)/6]³
2 h⁻¹(x) + 5 = (x + 1)³/216
2 h⁻¹(x) = (x + 1)³/216 - 5
h⁻¹(x) = (x + 1)³/432 - 5/2

Can you tell us what the missing number is in this sequence? 7,10,15,22, ?, 42
Answer:
31
the difference between the numbers is the number, plus 2, so for example, the difference between 7 and 10 is 3, add two and you have 5, and ten plus 5 equals 15. Using this formula, we have 5+2=7, which is 15+7=22. For the missing number, we have 7 (the last number used) +2=9, so, 22+9=31.

Nicholas is 12 years old and he has collected 459 trading cards. Phillip is 14 years old and he has collected 721 trading cards. How many more cards does Phillip have than Nicholas?
Phillip has _____
more cards than Nicholas.
Answer: Phillip has 262 more cards than Nicholas
Step-by-step explanation:
Since we are looking for how many more cards Phillip has compared to Nicholas we can subtract Nicholas' amount from Phillip's amount to see how much more he has.
721-459=262
Taking a simple difference, we can see that Phillip has _262_
more cards than Nicholas.
How many more cards does Phillip have than Nicholas?To find this, we need to take the difference between the number of cards that Philip has and the number of cards that Nicholas has, so we just need to solve a subtraction:
Phillip's cards - Nicholas' cards
Where:
Phillip's cards = 721
Nicholas' cards = 459
Then the difference is:
721 - 459 = 262
So we can see that Phillip has 262 more cards than Nicholas.

Answer:
3(x+2)/(2(x+4))
Step-by-step explanation:
A compound fraction is simplified by rewriting it as a simple fraction, and reducing it to lowest terms by cancelling common factors from numerator and denominator. The division of one fraction by another is accomplished in the usual way: multiply the numerator by the inverse of the denominator.

If secθ = -6.743, find the two values of θ
between 0° and 360°. Round your answers to one
decimal place.
Answer:
Θ ≈ 98.5° , 261.5°
Step-by-step explanation:
using the identity
cosΘ = [tex]\frac{1}{sec0}[/tex] , then
cosΘ = [tex]\frac{1}{-6.743}[/tex] ≈ - 0.1483
since cosΘ < 0 then Θ is in 2nd and 3rd quadrants
Θ = [tex]cos^{-1}[/tex] (- 0.1483) ≈ 98.5° ← in 2nd quadrant
related acute angle = 180° - 98.5° = 81.5° , then
Θ = 180° + 81.5° = 261.5° ← in 3rd quadrant

Cooper gave out a survey to some students in his school about their favorite color. Students could choose between red and blue. 129 of those surveyed said their favorite color was red. 57% of the students surveyed said their favorite color was blue. How many students were surveyed in total?
Using proportions, it is found that since 43% of the total amount is 129, 300 students were surveyed in total.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, since 57% of the students surveyed said their favorite color was blue, hence 100 - 57 = 43% said it was red, and this amount is of 129 students, hence:
0.43n = 129
n = 129/0.43.
n = 300.
300 students were surveyed in total.

4−2(3+7)=4−2⋅3−2⋅7
4−2(3+7)=4+−2⋅3+−2⋅7
4−2(3+7)=4−2⋅3+2⋅7
4−2(3+7)=4−(2⋅3+2⋅7)
Answer:
First and second are both true.
Third and fourth are not true.
Step-by-step explanation:
4−2(3+7)=4−2⋅3−2⋅7
4−2(3+7)= 4 - 2(3+7) [ -2*3 - 2*7 : the -2 can be removed from -2*3-2*7 to make -2(3 + 7); communative] This results in 4-2(3+7), the same on the left side
4−2(3+7)=4+−2⋅3+−2⋅7
The (4+-2*3+-2*7) can be written as (4-2*3-2*7) to simplify the "-+" to simply "-". That can be written as 4 - 2(3+7), the same as on the left side.
4−2(3+7)=4−2⋅3+2⋅7
The right side, 4-2*3+2*7, can be written as 4-2(3-7), which is NOT the same as on the left.4−2(3+7)=4−(2⋅3+2⋅7)
The right side can be written as 4-2(3-7), which is not the same as on the left side.
