Rashid [163]
You have to do mutiplication. how do you know that you have to do mutiplcation because the (of) it means times. so  26 * 2.21 = 0.5746
         2.21/x=100/26
<span>(2.21/x)*x=(100/26)*x      </span>
<span>2.21=3.8461538461538*x      
</span>(3.8461538461538) to get x
<span>2.21/3.8461538461538=x </span>
<span>0.5746=x </span>

Answer:

  10

Step-by-step explanation:

Using the distance formula, the distance is ...

  d = √((x2 -x1)^2 +(y2 -y1)^2)

  d = √((-2-4)^2 +(-4-4)^2) = √((-6)^2 +(-8)^2) = √(36 +64)

  d = √100 = 10

The distance between the two points is 10 units.

Assume f(x) = -2x+8 and g(x) = 5x. What is the value of (f o g)(3)?
makkiz [27]

Answer: C

Step-by-step explanation:

(fog)(3) is the same as finding f(g(3)). To solve, we first need to solve g(3). then, we solve for f(g(3)).

g(3)=5(3)                  [multiply]

g(3)=15

Now, we plug in 15 into f(x).

f(g(3))=-2(15)+8       [multiply]

f(g(3))=-30+8           [add]

f(g(3))=-22

Now, we know that C is the correct answer.
