Answer:
1.6 hours
Step-by-step explanation:
h = hours
rate * time = distance
time = distance / rate
h = 92.8 / 58
h = 1.6 hours
1.6 hours = 1 hour 36 minutes
The first thing we must do for this case is to complete the table.
We have then:
For f (x) = 2x + 24:
f (-2) = 2 (-2) + 24 = 20
f (-1) = 2 (-1) + 24 = 22
f (0) = 2 (0) + 24 = 24
f (1) = 2 (1) + 24 = 26
f (2) = 2 (2) + 24 = 28
For g (x) = 5 (0.5) ^ x:
g (-2) = 5 (0.5) ^ - 2 = 20
g (-1) = 5 (0.5) ^ - 1 = 10
g (0) = 5 (0.5) ^ 0 = 5
g (1) = 5 (0.5) ^ 1 = 2.5
g (2) = 5 (0.5) ^ 2 = 1.25
The table is:
x f(x) g(x)
-2 20 20
-1 22 10
0 24 5
1 26 2.5
2 28 1.25
f (x) = g (x) occurs for:
x = -2
Answer:
-2 20 20
-1 22 10
0 24 5
1 26 2.5
2 28 1.25
f (x) = g (x) ----> x = -2
To determine the expected total value of the investment after 20 years, we simply plug in the given to the prepared equation,
A = P x (1.12^n)
Substituting the known values,
A = ($5000) x (1.12^20)
A = $48,231.47
Thus, the expected amount of your purchase is $48,231.47.
