Answer:
an = -3·2^(n-1)
Step-by-step explanation:
The first term is a1 = -3.
The common ratio is r = -6/-3 = 2.
The given formula tells you the formula for this sequence is ...
an = -3·2^(n-1)
Answer:
Correct option: first one
Step-by-step explanation:
The equation f(x) = 5x + 1 is a function, because each value of x gives only one value of y.
Now let's find the inverse by switching f(x) by x and x by f'(x), then isolating f'(x):
The inverse f'(x) is also a function, because each value of x gives only one value of x.
So we have that both the equation and its inverse are function, therefore the correct answer is the first option.
It is given that f(t) = -16t² + 32t + 90
<span>The average rate of change will be calculated as following
</span>
At t₁ = 4 ⇒⇒⇒ f(t₁) = -16*(4)² + 32*(4) + 90 = -38
At t₂ = 6 ⇒⇒⇒ f(t₂) = -16*(6)² + 32*(6) + 90 = -294
∴
<span>So, The average rate of change of f(t) from t = 4 seconds to t = 6 seconds is
128 feet per second .
