Part A:
10p + 12v > 3200
p > 12000
v < 15000
(imagine they have the line underneath the symbols)
Part B:
at least 14,000 cups of plain yogurt
(make sure to convert the dollars to cents so that it is accurate)
math:
10p + 12(15000) > 320000
10p > 140000
p > 14000
4000.00 x 2.0 = $80.00 per year x 2 years = $160.00 so 6 months would earn $40.00 taking it to the $200, so 2 yrs 6 mos.
The answer is -4. Convert into common denom.
Answer:
N = 74(1/2)^(t/2.8)
Step-by-step explanation:
The exponential function expressing a half-life relation can be written ...
amount = (initial amount) × (1/2)^(t/(half-life))
For the numbers given in this problem, this is ...
N = 74(1/2)^(t/2.8)
__
Some folks like to express these relations in the form ...
N = 74e^(-kt)
In this form, the value of k is ...
k = ln(2)/(half-life) ≈ 0.693147/2.8 ≈ 0.24755
N = 74e^(-0.24755t)
Answer:
"35.84 years" is the appropriate solution.
Step-by-step explanation:
The given values are:
Rate of savings generation,
System cost to install,
= $30000
Now,
The total savings will be:
⇒
On substituting the values, we get
⇒
⇒
When,
Savings = 0
t = 0, then
⇒
⇒
The formula will be:
⇒
On putting the values in the above formula, we get
⇒
On taking log, we get
⇒
