Correct question:
A rain drop hitting a lake makes a circular ripple. Suppose the radius, in inches, grows as a function of time in minutes according to r(t)=26√(t+1), and answer the following questions. Find a function, A(t), for the area of the ripple as a function of time.
Step-by-step explanation:
The area of a circle is expressed as;
A = πr^2
Where, A = Area
r = radius
From the case above.
The radius of the ripple is a function of time
r = r(t) = 26√(t+1)
So,
A(t) = π[r(t)]^2
Substituting r(t),
A(t) = π(26√(t+1))^2
A(t) = π(676(t+1))
A(t) = 676π(t+1)
Answer:
The area is 54.6

Answer:
Mark spent 13 dollars on supplies for the dance. His goal is to make 20 dollars. How much worth of tickets does he need to sell to make his goal.
Step-by-step explanation:
To find this, we know we need to subtract 13 from something, in this case ticket sales. That number must be larger than 20, which in this case is the profits.
