This is an exponential function : f ( x ) = 2 · 5 ^x
The curve goes trough the points: ( 1, 10 ), ( 2, 50 ), ( 3, 250 ).
The multiplicative rate of change:
( 50 : 10 ) / ( 2 - 1 ) = 5 / 1 = 5
( 250 : 50 ) / ( 3 - 2 ) = 5 / 1 = 5
Answer: 5
Answer:
$150
Step-by-step explanation:
convert the percent to decimal, 0.40, then multiply it by 250 to get 100, then subtract, 250-100=$150
Answer and Step-by-step explanation:
No, you don't have to pay for anything to get expert-verified answers on your questions.
I'm not completely sure, but it could raise the chances of getting your answers to be that, or to have other people with those types answer your questions.
But no, you don't have to pay for anything. I didn't have to pay for anything and I got my answers to be expert verified in the past.

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
