F(x) = 2^x; h(x) = x^3 + x + 8
Table
x f(x) = 2^x h(x) = x^3 + x + 8
0 2^0 = 1 0 + 0 + 8 = 8
1 2^1 = 2 1^3 + 1 + 8 = 10
2 2^2 = 4 2^3 + 2 + 8 = 8 + 2 + 8 = 18
3 2^3 = 8 3^3 + 3 + 8 = 27 + 3 + 8 = 38
4 2^2 = 16 4^3 + 4 + 8 = 76
10 2^10 = 1024 10^3 +10 + 8 = 1018
9 2^9 = 512 9^3 + 9 + 8 = 729 + 9 + 8 = 746
Answer: an approximate value of 10
The value of x = -3/2 .
<h3>What is an Equation ?</h3>
An equation is a mathematical statement that relates unknown variable to constants to determine their value.
The equation given is
(2x+3 ) / 7 Divided by 1 = 0
2x +3 = 0
2x = -3
x = -3/2
Therefore the value of x = -3/2 .
The complete equation is
(2x+3)/7

Make a proportion
x = the amount of miles walked in 137.5 min
25 137.5
--- = --------
2 x
cross multiply
25x = 275
divide both sides by 25
x = 11
paul walked 11 miles in 137.5 minutes
Answer:
C. 4 weeks
Step-by-step explanation:
We have the formula
We are looking for the value of t (number of weeks) when s = 150.
So, we isolate t (well, almost isolate, because it would be hard to read)
If we replace s by 150 we get:
We have 7t = 30.25. If we divide both sides by 7 we get the number of weeks: 4.32... so rounding it down to 4.
