The amount of interest of the money invested in a savings account is calculated through the equation,
I = Prn
where I is the interest, P is the principal, r is the decimal equivalent of the given rate, and n is the number of years. In this item, we assume that n is equal to 1.
Solving for the interests,
$200: I = ($200)(0.03)(1) = $6
$150: I = ($150)(0.03)(1) = $4.5
The difference between the two calculated interests is $1.5.
Therefore, you could have earned $1.5 more if you invested $200 rather than $150.

If you don't know the first derivative of
, but you do for
and
, you can derive the former via the quotient rule:


or if you know the derivative of
:


As for the second derivative, you can use the power/chain rules:

or if you don't know the derivative of
,


which is the same as the previous result since

Answer:
it is b

the answer is b because
Answer:
16 ft/s²
Step-by-step explanation:
s(t) = sin(t) - 4cos(2t)
Differentiation for v
v(t) = cos(t) + 8sin(2t)
Differentiate for a
a(t) = -sin(t) + 16cos(2t)
At t = π
a(π) = -sin(π) + 16cos(2π)
= 0 + 16
= 16
