-268/21
First you multiply 22 times 1/3 which will give you 22 1/3 then you make it into a mixed number by multiplying the bottom number of the fraction with the whole number and then adding it with the top number of the fraction in this case is (22*3)+1 then you multiply fractions normally by multiplying the top and bottom numbers with each other In this case would be -4*67 and 3*7 and the you get your answer (simplify if necessary)

If f(x) and f–1(x) are inverse functions of each other and f(x)=2x+5, what is f–1(8)?
yarga [219]

f(x)=2x+5

first find inverse

write it without f(x)

y = 2x +  5

x = 2y + 5  swap the variables, now solve for y

-  5      -5

x - 5 = 2y

/2         /2  divide both sides by 2

(x-5)/2 = y


so f-1(x) = (x-5)/2

f-1(8) = (8-5)/2

         = (3)/2

f-1(8) = 3/2

Which expression represents the height of the pyramid? StartFraction 3 V Over y squared EndFraction units (3 V minus y squared)
maxonik [38]

Answer:

Height = 3v/y² units

StartFraction 3 V Over y squared EndFraction units

Step-by-step explanation:

The volume of a solid right pyramid with a square base is v units3 and the length of the base edge is y units. which expression represents the height of the pyramid? units (3v – y2) units (v – 3y2) units units

Volume of a solid right pyramid = 1/3 × area of the base × height

Volume of a solid right pyramid = v units³

Area of the base = y² unit²

Volume of a solid right pyramid = 1/3 × area of the base × height

v = 1/3 × y² × height

Height = v ÷ 1/3 × y²

= v × 3/1y²

= (v × 3) / y²

= 3v / y²

Height = 3v/y² units

StartFraction 3 V Over y squared EndFraction units
