Step-by-step explanation:
In order to find the hypothenuse, you need to do . Which equals 164. Therefore, since , a=8, b=10, and c=.
Answer:
See verification below
Step-by-step explanation:
We can differentiate P(t) respect to t with usual rules (quotient, exponential, and sum) and rearrange the result. First, note that
Now, differentiate to obtain
To obtain the required form, extract a factor in both the numerator and denominator:
1/x is smallest when x is the largest it can be, so it is 1/3
1/y is smallest when y is the largest it can be, so it is 1/5
The average of 1/3 is 1/5 can be found by adding them together and dividing by 2:
1/3 + 1/5 = 5/15 + 3/15 = 8/15
Divide it by 2:
4/15
The answer is C.
