Answer:
Benjamin travels 420 m in 100 seconds .
Step-by-step explanation:
Given : The tire of his unicycle has a circumference of 2.8 m.
The tire revolves 1.5 times per second
To Find: What is the distance Benjamin travels in 100 seconds?
Solution :
Since we are given that he wheel makes 1.5 revolutions per second.
It makes revolutions in 100 seconds =
=
Thus it makes 150 revolutions in 100 seconds
Now, Each revolution travels 2.8 m.
So, 15 revolutions it will travel =
=
Thus Benjamin travels 420 m in 100 seconds .
Answer:
420m

Answer:
Step-by-step explanation:
Composition of two functions can be obtained by replacing inner function in place of x of outer function and then plugging back the actual value of inner function f(x) and then simplifying it gives g(f(x)) which is usually called gof(x) .
f(x) = -
g(x) = 3x
g(f(x) ) = 3 f(x)
=3 ()
=
Answer:
-9x²
Step-by-step explanation:
We have given two functions.
We have to find their composition.
f(x) = -3x² and g(x) = 3x
(gof)(x) = g(f(x)) = ?
Firstly , we have to put the value of f(x) in g(f(x)).
Putting given values, we have
g(f(x)) = g(-3x²)
g(f(x)) = 3(-3x²)
g(f(x)) = -9x² which is the answer.
