Answer: 4.13 x 10^4
Step-by-step explanation: You have to just count the places such as the tens all the way to the thousands which leaves you with the exponent of 4.
For this case, the first thing we must do is define variables.
We have then:
x: number of minutes
y: final temperature
We write then the equation that models the problem:

For y = 20 we have:

Clearing x:
Answer:
The temperature of the water will be 20 degree celcius after 150 minutes
Answer: he purchased 16 ride tickets.
Step-by-step explanation:
Let x represent the number of ride tickets that he purchased.
Let y represent the number of game tickets that he purchased.
Levi purchased a total of 50 ride tickets and game tickets at the amusement park. It means that
x + y = 50
If ride tickets cost $.75 each and game tickets cost $.50 each and the total amount spent on the tickets is $29, it means that
0.75x + 0.5y = 29- - - - - - - - - - - -1
Substituting x = 50 - y into equation 1, it becomes
0.75(50 - y) + 0.5y = 29
37.5 - 0.75y + 0.5y = 29
- 0.75y + 0.5y = 29 - 37.5
- 0.25y = - 8.5
y = - 8.5/-0.25
y = 34
x = 50 - y = 50 - 34
x = 16
Based on the given graph, the time when the softball reaches its maximum height is about 1.8 seconds.
<h3>When is the softball at it highest?</h3>
The softball is at its maximum height at the point where the curve begins to go back down.
This means the maximum height is 50 feet.
The time when this softball reaches this height is between 1 and 2 seconds at 0.8.
The time the softball reaches its maximum height is therefore 1.8 seconds.
