Is the inverse of a function always a function?explain
Answer:
Step-by-step explanation:
The inverse of a function may not always be a function! The original function must be a one-to-one function to guarantee that its inverse will also be a function. A function is a one-to-one function if and only if each second element corresponds to one and only one first element. (Each x and y value is used only once.)
Answer:
The inverse is not a function: A function's inverse may not always be a function. The function (blue) f(x)=x2 f ( x ) = x 2 , includes the points (−1,1) and (1,1) . Therefore, the inverse would include the points: (1,−1) and (1,1) which the input value repeats, and therefore is not a function.

28 is what percent of 64?
Solution:
Note that:
64 × x/100 = 28Simplifying the LHS:
64 × x/100 = 28=> 64x/100 = 28Using cross multiplication:
64x/100 = 28=> 64x = 2800Divide 64 both sides.
=> x = 2800/64 = 43.75%28 is 43.75% of 64

During a school fundraiser contest, Georgia sold 49 coupon books and Molly sold 79 coupon books. The total number of coupon books sold during the contest was 354 books. What's the ratio of the number of coupon books that Georgia and Molly sold to the total books sold?
Step-by-step explanation:
During a school fundraiser contest, Georgia sold 49 coupon books and Molly sold 79 coupon books. The total number of coupon books sold during the contest was 354 books. Total sold by Georgia + Molly = 49+79=128. Ratio of the number of coupon books that Georgia and Molly sold to the total books sold is then 128:354.

A flower pot has a diameter of 6 feet. What is the area of the flower pot, to the nearest whole number?
Answer:
28 ft²
Step-by-step explanation:
The area of a circle is [tex]\pi r^2[/tex], where r = radius. To find the radius, we split the diameter in half.
6/2 = 3Thus, the radius is 3.Now, let's find the area of the circle and approximate pi to 3.14.
[tex]3.14*3^2[/tex] [tex]3.14*9[/tex] [tex]28.26[/tex] 28.26 ≈ 28 ft²Therefore, the answer is 28 ft².

Madeline uses a scale model of a design she plans to paint on a wall she uses the key 1 CM =1.5 ft. One gallon of paint will cover 400 square feet of wall .How many gallons of paint will Madeline use? Enter your answer as a decimal in the box.
Madeline would need to use 0.82 gallon of paint
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given the scale 1 cm = 1.5 ft.
(1 cm)² = (1.5 ft.)²; 1 cm² = 2.25 ft²
The area of the figure = area of trapezoid + area of triangle
Area = (1/2) * (10) * (14 + 4) + (1/2) * 14 * (18 - 10) = 146 cm²
146 cm² = 146 cm² * 2.25 ft² per cm² = 328.5 ft²
1 gallon = 400 ft², hence:
328.5 ft² = 328.5 ft² * 1 gallon per 400 ft² = 0.82 gallon
Madeline would need to use 0.82 gallon of paint

The first number in a pattern is 156. The pattern follows the rule subtract 19. What are the next three numbers?
1 137, 118, 99
2 118, 99, 80
3 137, 119, 100
4 137, 118, 98
Answer:
A
The answer would be A because what is 156- 19=137 so we now take out number 2/B
137-19=118 So that means we can eliminate number 3/c that says 119 so that's out now.
And for last number the 3rd number to subtract is what is 118-19=99 so we just eliminated number 4 that says 98.
And the only number that followed our answers and ad the same answer for us was A so lets go with A.
Hope this helps have a great day:)

Factor completely
y^ 3-6y^2+5y
Answer:
please mark me as brainlist pleaseStep-by-step explanation:
The first term is, y2 its coefficient is 1 .
The middle term is, -6y its coefficient is -6 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 1 • 5 = 5
Step-2 : Find two factors of 5 whose sum equals the coefficient of the middle term, which is -6 .
-5 + -1 = -6 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and -1
y2 - 5y - 1y - 5
Step-4 : Add up the first 2 terms, pulling out like factors :
y • (y-5)
Add up the last 2 terms, pulling out common factors :
1 • (y-5)
Step-5 : Add up the four terms of step 4 :
(y-1) • (y-5)
Which is the desired factorization
Can you help me find t value in this problem?
we have a maximum at t = 0, where the maximum is y = 30.
We have a minimum at t = -1 and t = 1, where the minimum is y = 20.
How to find the maximums and minimums?
These are given by the zeros of the first derivation.
In this case, the function is:
w(t) = 10t^4 - 20t^2 + 30.
The first derivation is:
w'(t) = 4*10t^3 - 2*20t
w'(t) = 40t^3 - 40t
The zeros are:
0 = 40t^3 - 40t
We can rewrite this as:
0 = t*(40t^2 - 40)
So one zero is at t = 0, the other two are given by:
0 = 40t^2 - 40
40/40 = t^2
±√1 = ±1 = t
So we have 3 roots:
t = -1, 0, 1
We can just evaluate the function in these 3 values to see which ones are maximums and minimums.
w(-1) = 10*(-1)^4 - 20*(-1)^2 + 30 = 10 - 20 + 30 = 20
w(0) = 10*0^4 - 20*0^2 + 30 = 30
w(1) = 10*(1)^4 - 20*(1)^2 + 30 = 20
So we have a maximum at x = 0, where the maximum is y = 30.
We have a minimum at x = -1 and x = 1, where the minimum is y = 20.
