Answer:
The inner function is and the outer function is .
The derivative of the function is .
Step-by-step explanation:
A composite function can be written as , where and are basic functions.
For the function .
The inner function is the part we evaluate first. Frequently, we can identify the correct expression because it will appear within a grouping symbol one or more times in our composed function.
Here, we have inside parentheses. So is the inner function and the outer function is .
The chain rule says:
It tells us how to differentiate composite functions.
The function is the composition, , of
outside function:
inside function:
The derivative of this is computed as
The derivative of the function is .
When Peter does this, he is creating two sides of a right-angle triangle. The distance from his house to that point will be the hypotenuse of the triangle thus, to work out the length of the hypotenuse, we have to use Pythagoras Theorem! So:
a² + b² = c²
15² + 15² = c²
225 + 225 = c²
450 = c²
15√2 = c
21.21320344 = c
So, this rounded to the nearest tenth would be:
21.2 meters !
Answer:
2/3
Step-by-step explanation:
A = Student studying Math
B = Student studying Science
P(B|A) = P(A and B) ÷ P(A).
P(B|A) means the probability of event B given event A.
Given :
P(A and B) = 0.40.
Also P(A) = 0.60.
P(B|A) = 0.40 ÷ 0.60 = 2 ÷ 3.
So, the answer is 2/3.
