Answer

f(-4) = 125, g(6) = -13

Step-by-step explanation:

all of those symbols might look really scary, but really all the problem is asking you to do is substitute -4 into the x in f(x) and 6 into the x in g(x) -- basically, f(-4) = -2((-4)^{3}) - 3 = 125, and g(6) = -2(6) - 1 = -13. there are your answers!

C)<br> A bus drives for 3/2 hours at an average speed of 56 mph.<br> How far does the bus drive?
natta225 [31]

Answer:

The bus drives 84 miles

Step-by-step explanation:

The question relates to relationship between average speed and time

The given parameters are;

The time duration in which the bus drives = 3/2 hours = 1.5 hours

The average speed of the bus = 56 mph

The formula average speed is given as follows;

Average \ speed = \dfrac{The \ total \ distance \ driven}{The \ time \ duration \ of \ travel}

Therefore, we have;

The total distance driven = Average speed × The time duration of travel

The total distance driven = The distance the bus drives

Substituting the given values, gives;

The distance the bus drives = 56 miles/hour × 1.5 hours = 84 miles

The distance the bus drives = 84 miles.

Help please! :) Its really late and cant process that much math, i did the others, but this first one confused me.

Use pythagorean theorem to find the bottom side of the left triangle.
12^2+b^2=15^2
144+b^2= 225
b^2= 81
b=9
you will then subtract 9 from 25 to get 16
area from the triangle on the right
A=(1/2)16*12
A= 96 in^2
then for the triangle on the right
A= (1/2)12*9
A= 54 in^2
then add the two areas together

Total Area= 150 in^2
