Find f^-1(x) for f(x) = 1/x^3

kow [346]

Answer: $f^{-1}(x) = \frac{\sqrt[3]{x^{2}}}{x}$

<u>Step-by-step explanation:</u>

$y = \frac{1}{x^{3}}$

Inverse is when you swap the x's and y's and then solve for "y":

$x = \frac{1}{y^{3}}$

$y^{3} = \frac{1}{x}$

$y = \frac{1}{\sqrt[3]{x}}$

$y = \frac{1}{\sqrt[3]{x}}*(\frac{\sqrt[3]{x}}{\sqrt[3]{x}})^{2}$

$y = \frac{\sqrt[3]{x^{2}}}{x}$

A full load for a small truck to haul is 2/3 ton of gravel. The truck is hauling 1/2 ton of gravel. Write a division sentence th

Romashka [77]

Answer:

The truck is hauling 3/4 of a full load

Step-by-step explanation:

we know that

2/3 ton of gravel represent the 100% of a full load

Find out how much of a full load the truck is hauling with 1/2 ton of gravel, using proportion

Let

x ----> the percentage of a full load

$\frac{(2/3)}{100\%}=\frac{(1/2)}{x}\\\\x=100\%(1/2)/(2/3)\\\\x=100\%(3/4)\\\\x=75\%$

Convert to fraction number

$75\%=\frac{75}{100}=\frac{3}{4}$

therefore

The truck is hauling 3/4 of a full load

Someone drove 20 miles in 24 minutes at this rate how many miles did they drive in 6 minutes

nikklg [1K]

Distance = rate * time (I will abbreviate as d = rt)
d = rt, so r = d/t
r = 20mi/24min
= 0.833333 mi/min.

d = rt again for the new time
d = 0.8333333 mi/min * 6 min = 5 miles
