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

Is C + 11 = 20; c =9 a solution if the equation

Deffense [45]

Answer:

Step-by-step explanation:

c + 11 = 20....subtract 11 from both sides

c = 20 - 11

c = 9

and u know that u can check ur answer by subbing it back into the equation

c + 11 = 20

9 + 11 = 20

20 = 20 (correct)

so yes, ur answer c = 9 is correct

4. An airplane at T(80,20) needs to fly to both U(20,60) and V(110,85). What is the shortest possible distance for the trip?

damaskus [11]

The distance formula for two points in a plane is
D=sqrt( (x1-x2)^2 + (y1-y2)^2 )
From T to U
D= sqrt((80-20)^2 + (20-60)^2) = 72.11
Then flying from U to V
D= sqrt((20-110)^2 + (60-85)^2) = 93.4
So T to U to V = 72.11+93.4 = 165.5
BUT checking also T to V to U
From T to V
D= sqrt((80-110)^2 + (20-85)^2) = 71.6
Then from V to U
D= sqrt((110-20)^2 + (85-60)^2) = 93.4
So from T to V to U = 165
Pretty much the same both directions
So yes the answer is A
