Answer:
C. 350
Step-by-step explanation:
A sample of 50 different coloured balls are removed from total golf balls made.
Out of these 50 coloured balls, 8 balls are pink
Now, to calculate the total number of golf balls made,
we can use the concept of proportion
=
total golf balls made =
total golf balls made = 350
<u>Solution-</u>
A pebble is dropped into a calm pond, causing ripples in the form of concentric circles.
The radius of the outer ripple is given by r(t)= 0.6t,
where t is the time in seconds after the pebble strikes the water.
The area of the circle is given by the function
(a ◦ r)(t) = a(r(t)) ( ∵ Using function composition / plugging in the second function into the first function)
⇒
∴ This is the expression for area of circle of outermost ripple, at time t after the pebble strikes the water.
