Answer: f(-2)=-6

Step-by-step explanation:

For this exercise it is important to remember the multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-

You have the following function provided in the exercise, which represents the path traveled:

f(x) = 4x + 2

In order to find the value of f(-2) you can follow these steps:

1. You need to substitute x=-2 into the function, then:

f(-2) = 4(-2)+ 2

2. Finally you must evaluate. Then you get:

f(-2) =-8+ 2\\\\f(-2)=-6

What is 5 1/2 of 60%
EleoNora [17]
You mean 60%of 5 1/2? that makes more sense...


i would do it like this:

\frac{60}{100}* 5\frac{1}{2}

(60% is the same as \frac{60}{100}

5\frac{1}{2}=\frac{11}{2}

(so that there is no confusion, i've put it into an improper fraction

now we can multiply:
\frac{60}{100}* \frac{11}{2}=

\frac{6}{10}* \frac{11}{2}=

\frac{3}{5}* \frac{1}{2}=



\frac{3*11}{10}=

\frac{33}{10}=

which is 3.3.

so 60% of 5 and a half is 3.3.

What is the volume of a sphere with a radius of 4.5 inches?
schepotkina [342]

Answer:

D 381.7 in^3

Step-by-step explanation:

V=4/3pi r^3

V=4/3pi 4.5^3

4/3x3.14x4.5x4.5x4.5

It is approximately 381.51 when you use 3.14 as pi. This is closest to answer D, so I would assume it is that.

Sorry, I thought it said circle at first.
