For the function f(x)=5x^3-6, find f^-1
max2010maxim [7]

Answer:

f^{-1} means the inverse function

f^{-1} = \sqrt[3]{(x + 6)/5}

Step-by-step explanation:

f^{-1} means the inverse function

to find an inverse function, flip the x and y variables and solve for y

f(x) = 5x^3 - 6

y = 5x^3 - 6

x = 5y^3 - 6

x + 6 = 5y^3

(x + 6)/5 = y^3

\sqrt[3]{(x + 6)/5} = y

Natasha, Mark and Henry share some sweets in the ratio 7:3:2. Natasha gets 75 more sweets than Henry. How many sweets are there
Solnce55 [7]

Answer:

180

Step-by-step explanation:

Given the ratio = 7 : 3 : 2 = 7x : 3x : 2x ( x is a multiplier ), then

7x = 2x + 75 ( Natasha gets 75 more sweets than Henry )

Subtract 2x from both sides

5x = 75 ( divide both sides by 5 )

x = 15

Thus

total number of sweets = 7x + 3x + 2x = 12x = 12 × 15 = 180

Shad Yarbrough wants to consider the cost per use of a high-end desk top computer he is considering for his web site business. T
Sonja [21]

Answer:

Shad's cost per use will be $ 2.80.

Step-by-step explanation:

Since Shad Yarbrough wants to consider the cost per use of a high-end desk top computer he is considering for his web site business, and the computer costs $ 1,750 and has a life expectancy of four years, if Shad feels he would use the computer three days a week, on average, to determine what is Shad's cost per use, the following calculation must be performed:

Weeks per year = 52

52 x 4 = 208

208 x 3 = 624

1750/624 = X

2.80 = X

Thus, Shad's cost per use will be $ 2.80.
