Both the numerator and denominator are cubes: (3^3)/(4^3). because they are both to the power of 3, this can be simplified to (3/4)^3, ie x = (3/4)

Miranda bought a brand-new cell phone. She noticed that the battery
Artyom0805 [142]

The function model that represents the amount of battery left after a period  of time is y = 1 ₋ 10%x

Given, Miranda bought a new cell phone which is consuming battery at a rate of 5% for every half an hour.

We are required to establish a function model that depicts how much battery is remaining after a certain amount of time.

Let y represent the amount of battery left.

and x represent the number of hours.

Then 5% per half an hour = 5% × 2 = 10%

Now frame the function model:

The amount of battery left = 1 ₋ (rate percent at which battery is being consumed)(The number of hours left)

⇒ y = 1 ₋ 10%(x)

⇒ y = 1 ₋ 10%x

As a result, we obtained the function model for the battery's remaining capacity as y = 1 ₋ 10%x

What is greater 4.5 or 3.75
const2013 [10]

Answer:

4.5

Step-by-step explanation:

4.5>3.75

If we forgot about the decimals, we would have 4 and 3, and 4 is automatically larger; even with the decimals.

Hope this helps!
