The key word is “above” so the answer is A! :) (could I please have brainliest?)
Given:

To find:
Which statement are true?
Solution:
Option A: The entire expression is a sum.
It is true because it performed addition operation.
Option B: The coefficient of s is 3.

It is not true because the coefficient of s is
.
Option C: The term
is a quotient.
If we divide 7 by r, we obtain a quotient.
So it is true.
Option D: The term
has a variable.
It is not true because it does not contain any variable.
Therefore the entire expression is a sum and the term
is a quotient are true statement.
Step-by-step explanation:
∫₀³⁰ (r/V C₀ e^(-rt/V)) dt
If u = -rt/V, then du = -r/V dt.
∫ -C₀ e^u du
-C₀ ∫ e^u du
-C₀ e^u + C
-C₀ e^(-rt/V) + C
Evaluate between t=0 and t=30.
-C₀ e^(-30r/V) − -C₀ e^(-0r/V)
-C₀ e^(-30r/V) + C₀
C₀ (-e^(-30r/V) + 1)
I got the same answer. Try changing the lowercase v to an uppercase V.
<span>Circumference of a circle = 2 π r
(where r is the radius)
Area of a circle = π r^2
(where r is the radius)
you have to find the radius
C = 2π unit
r = 1 unit
Area = π square units
