The number of subscribers y to a website after t years is shown by the equation below.

y = 50(1.75)t

which conclusion is correct about the number of subscribers to the website?

it increased by 75% every year.

it decreased by 75% every year.

it increased by 50% every year.

it decreased by 50% every year.

-It increased by 75% every year.

Explanation:-

Given: The number of subscribers y to a website after t years is shown by the equation , where 50 is the initial number of subscribers to a website and t is the time period is years.

The above equation can be rewrite as

which is equivalent to the exponential growth function with growth rate r=0.75=75%

⇒ The number of subscribers to a website increased by 75% every year.

⇒ First option is correct.

step-by-step explanation:

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
