Answer:
B. 1.5r + 5
Step-by-step explanation:
Because he bought 1 yardstick and r rulers so to find the total number you need to add both numbers together.
Answer:
- y = 22·e^(0.3001t), growing
- annual rate: 35%
- continuous rate: 30.01%
Step-by-step explanation:
When an exponential function is in the form ...
y = ab^t
the factor 'b' is called the growth factor. When t is in years, it is related to the annual growth rate (r) by ...
b = 1 +r
In the alternate form, this can be written ...
y = a·e^(kt)
Comparing the forms, we see that ...
b = e^k ⇒ k = ln(b)
__
<h3>(a)</h3>
y = 22·1.35^t
k = ln(1.35) ≈ 0.3001
y = 22·e^(0.3001t)
The growth factor is greater than 1, so the function is growing.
__
<h3>(b)</h3>
The annual growth rate is ...
r = 1.35 -1 = 0.35 = 35.00%
__
<h3>(c)</h3>
The continuous growth rate is ...
k = 0.3001 = 30.01%
A) $14/hr B) Austin
Step-by-step explanation:
A)
If he earns $140 in 10 hours you can divide 140 by 10 to find out how much he makes per hour
B)
Sarah makes $13/hr which is $1 less than Austin
