Answers

Answer 1

Answer:

Answer:

The sign of acceleration is positive.

Step-by-step explanation:

Consider the provided information.

It is given that A student drops a penny from the top of a tower and decides that she will establish a coordinate system in which the direction of the penny's motion is positive.

Here the direction of the velocity is positive, and the velocity is increasing.

Acceleration is defined as the rate at which an object changes its velocity.

Since velocity is positive therefore the acceleration is also positive.

Hence, the sign of acceleration is positive.

A pool can be filled to 15,000 gallons of water. It takes 9 gallons per minute to fill the pool. How much minutes does it take to fill the pool?

Answers

Answer:

1666.7 minutes

Step-by-step explanation:

To find out how many minutes it takes to fill the pool, you can use the formula:

Time (minutes) = Total volume / Flow rate

In this case, the total volume of the pool is 15,000 gallons, and the flow rate is 9 gallons per minute.

Time (minutes) = 15,000 gallons / 9 gallons per minute

Time (minutes) = 1,666.67 minutes (rounded to two decimal places)

So, it takes approximately 1,666.67 minutes to fill the pool.

Solve the equation for y (Y-3)^2=4y-12

Answers

If you would like to solve the equation for y, you can do this using the following steps:

(y - 3)^2 = 4y - 12
y^2 - 6y + 9 - 4y + 12 = 0
y^2 - 10y + 21 = 0
(y - 7) * (y - 3) = 0
1. y = 7
2. y = 3

The correct result would be y = 7 or y = 3.
