Marina CMI [18]
Given:
Function y = 119.67(0.61)x

x = week 3.

F(3) = 119.67(0.61)(3)
F(3) = 119.67*1.83
F(3) = 218.9961

x = week 5

F(5) = 119.67(0.61)(5)
F(5) = 119.67 * 3.05
F(5) = 364.9935

ehidna [41]

Answer:

110.4622 = 110 (as followers cannot be in decimals).

Step-by-step explanation:

Given, growth rate is 1% = 0.01.

and it is for every 12 hours.

now, f(x) = f(1 + r)^t. where f= 100 (initial followers)

                            r = 0.01.

                             t =10 (1 for every 12 hours. so, 5 days = 120 hours = 10 times)

⇒ f(x) = 100(1+0.01)¹⁰ = 110.4622 = 110 followers.

It takes Emma 3/4 minutes to ride her bike a distance of 1/8 miles. What is Emma's average speed in miles per minute?
sp2606 [1]

Answer:

The answer is 1/6

Step-by-step explanation:

1/8 miles in 3/4 minutes

then, that means in 1 minute ( 1 min = 3/4 * 4/3) Emma will ride a distance of (1/8)*(4/3)= (1*4)/(8*3)= 1/6.

The answer is 1/6 (in 1 min she will ride 1/6 miles).

Hope that useful for you.

Ordered pairs are in the form (x, y). So, replace all variables with their values.
We have the ordered pair (0, 14). Replace x with its value and y with its value.

Now we have the inequality 14 > 0 + 12

Simplify the left-hand side.

14 > 0 + 12
14 > 12

So, the ordered pair (0, 14) is part of the solution set.
