Remember that direct variation means that you have a relationship of the form
y=kx

In this case it's a special equation, namely distance=rate*time. So first we have to find the rate given the information in the problem:
171=3r
57=r

Now we know that the rate is constant since Billy's distance varies directly with time. The next step is to find distance given a different amount time:
d=57*4.5

You can finish that one off!

How do you find the absolute extrema of this function?<br> f(x) = x+3x^(2/3); Interval is [-10,1]
Step2247 [10]
\bf f(x)=x+3x^{\frac{2}{3}}\implies \cfrac{dy}{dx}=1+3\left(\frac{2}{3}x^{-\frac{1}{3}}  \right)\implies \cfrac{dy}{dx}=1+\cfrac{2}{\sqrt[3]{x}}&#10;\\\\\\&#10;\cfrac{dy}{dx}=\cfrac{\sqrt[3]{x}+2}{\sqrt[3]{x}}\implies 0=\cfrac{\sqrt[3]{x}+2}{\sqrt[3]{x}}\implies 0=\sqrt[3]{x}+2\implies -2=\sqrt[3]{x}&#10;\\\\\\&#10;(-2)^3=x\implies \boxed{-8=x}\\\\&#10;-------------------------------\\\\&#10;0=\sqrt[3]{x}\implies \boxed{0=x}

now, f(0) = 0, and f(-8) is an imaginary value or no real value.

now, f(-10)   will also give us an imaginary value

and f(1) = 4

so, doing a first-derivative test on 0, is imaginary to the left and positive on the right, and before and after 1, is positive as well, so f(x) is going up on those intervals.

however, f(0) is 0 and f(1) is higher up, so the absolute maximum will have to be f(1), and we can use f(0) as a minimum, and since it's the only one, the absolute minimum.

the other two, the endpoint of -10 and the critical point of -8, do not yield any values for f(x).

A shipping carton is in the shape of a triangular prism. How many cubic inches
olga55 [171]

Answer: 90 inches

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a rectangular prism =area of the base x length  

Area of the base is the area of a triangle:

Area of a triangle = base x height x 1/2

Replacing with the values given:

A = 4 x 3 x 1/2 = 6 in2

Back on the volume formula:

V = A x h = 6 x 15 = 90 cubic inches  

Feel free to ask for more if needed or if you did not understand something.
