Answer:
r(s(-2)) = -2
Step-by-step explanation:
We are given these following functions:


Find the value of r(s (-2)).
First we find the composition of r and s functions. It is:

At x = -2

r(s(-2)) = -2
Answer:
<h2> 3hours 55 minute</h2>
Step-by-step explanation:
Step one:
Given data
distance= 160miles
velocity = 3/4 miles per minutes
Step two:
Required:
time
we know that velocity is
v=distance/time
times= distance/velocity
time=160/3/4
time= 160*4/3
time=640/3
time=213.33333minuts
Time= 3hours 55 minute
Answer:
-2.5 degrees
Step-by-step explanation:
The temperature decreased 18.5 degrees F in 7.4 hours.
-
-18.5/7.4 = -2.5 degrees F
The average change in temperature over the course of 7.4 hours is -2.5 degrees F.

Multiply the numerator and denominator by the same number.<span> Two fractions that are different but equivalent have, by definition, numerators and denominators that are multiples of each other. In other words, multiplying the numerator and denominator of a </span>fraction<span> by the same number will produce an equivalent fraction. Though the numbers in the new fraction will be different, the fractions will have the same value.</span><span>For instance, if we take the fraction 4/8 and multiply both the numerator and denominator by 2, we get (4×2)/(8×2) = 8/16. These two fractions are equivalent.(4×2)/(8×2) is essentially the same as 4/8 × 2/2 Remember that when multiplying two fractions, we multiply across, meaning numerator to numerator and denominator to denominator.Notice that 2/2 equals 1 when you carry out the division. Thus, it's easy to see why 4/8 and 8/16 are equivalent since multiplying 4/8 × (2/2) = 4/8 still. The same way it’s fair to say that 4/8 = 8/16.<span>Any given fraction has an infinite number of equivalent fractions. You can multiply the numerator and denominator by any whole number, no matter how large or small to obtain an equivalent fraction.</span></span>
Answer:
36
Step-by-step explanation:
There would be three on each edge. (Five, minus the two ends that have 3 sides painted.)
A cube has 12 edges.
12x3=36
