Answer:
<u><em>I HOPE IT WILL WORK</em></u>
Step-by-step explanation:
As for average rate of change we know
A(x)=f(5)-f(3)/(5-3)
where
f(x)=3 x 3 + 2 (1)
putting x=5 we get
f(5)=3(125)+2 =377
f(3)=83
hence putt in (1) we get
A(x)=294/2 =146
this is required average rate of change

Answer:
<h2> D=C/4</h2>
Step-by-step explanation:
Given that elevation of the cities are
A=72 feet
C=24 feet
D=1/4 of C
The expression for the elevation of city D is
D=C/4
substituting C=24 in the expression we have
D=24/4
D=6
The answer is positive because the elevation is above sea level
Answer: B
Step-by-step explanation:
1. You multiply 4 to both sides, which makes it 1:3.2
2. Multiply 10 to both sides, which makes it 10:32
3. Divide by 2, and the answer is 5:16, which is B.

Answer:
5.5%
Step-by-step explanation:
Given data
Simple interest = $137.50
Principal= $500
time = 5 years
We want to find the rate R
Simple interest= PRT/100
137.50 = 500*R*5/100
137.50=2500R/100
cross multiply
137.5*100= 2500R
13750= 2500R
divide both sides by 2500
R= 13750/2500
R=5.5%
Hence the rate is 5.5%
