A. a = 12, b = any number other than 24
Answer:
(A) 30772cm^2/s
(B) 153860cm^2/s
(C) 184632 cm^2/s
Step-by-step explanation:
We are given
speed of the ripple = 70cm/s
this speed is increasing the radius which means speed = radius /time
radius = speed*time
r= 70t
Now we know the area of the circle
A = π
this area will be increasing as ripples in water will spread out
upon differentiating
dA/dt = 2πr * 
dA/dt = 2π*70t*70 ( r= 70t , dr/dt = speed = 70)
dA/dt = 9800π*t
(A) after 1 second
dA/dt = 9800π*1=9800π = 30772cm^2/s
(B) after 5 seconds
dA/dt = 9800π*5 = 153860cm^2/s
(C) after 6 seconds
dA/dt = 9800π*6 = 184632 cm^2/s

Answer:
Oki! I'll help!
The answer is:
<u>Joy can buy 53 tickets.</u>

<em>Here is the whole work I did, so you can understand how to get the answer!</em>
<em>1. Divide 374 by 7</em>
374 ÷ 7 = 53.4
<em>2. Round to nearest whole number</em>
Since 4 in the tenth place is closer to zero than one, we round it down and get 53.
Oh the thing surrounding the whole work I did is just a spacer to make the answer not boring!
