The small cup is the better deal, with the medium you get 4 more ounces but pay 15 cents an ounce with the small you pay 14 cents an ounce.
A "derivative" is a rate of change.
The derivative of a plain old number is zero, since numbers never change.
Pi is a number. Its value never changes. Its derivative is zero.
The function is f(x) = 86(1.01)^7x; grows approximately at a rate of 1% daily
<h3>How to rewrite the function?</h3>
The function is given as:
f(x) = 86(1.08)^x
There are 7 days in a week.
This means that:
1 day = 1/7 week
So, x days is
x day = x/7 week
Substitute x/7 for x in
f(x) = 86(1.08)^(x/7)
Rewrite as:
f(x) = 86(1.08^1/7)^x
Evaluate
f(x) = 86(1.01)^x
In the above, we have:
r = 1.01 - 1
Evaluate
r = 0.01
Express as percentage
r = 1%
Hence, the function is f(x) = 86(1.01)^7x; grows approximately at a rate of 1% daily

Answer:
angle x equals 25
Step-by-step explanation:
130 + 25 = 155
