Leonel runs on different trails near his home for exercise. uses of positioning device to record how far from home he is when he
stops running. the scatterplot shows leonel's distance from his house when he stops running in relation to the length of time that he spent running .
F) as the number of minutes Lionel is running increases, the distance from home when he stops running increases .
G . As the number of minutes leonel is running increases, the distance from home when he stops running remains the same.
H. As the number of minutes leonel is running increases, the distance from home when he stops running decreases.
J.There is no relationship between the number of minutes leonel spends running and the distance from home when he stops running.

Answer:
7 seconds.
Step-by-step explanation:
We have been given that the height of a flare fired from the deck of a ship in distress can be modeled by , where h is the height of the flare above water and t is the time in seconds.
The ball will hit the ground, when height will be 0 meters, so we will equate to find the time when ball will hit the ground as:
Using quadratic formula, we will get:
Since time cannot be negative, therefore, it will take 7 seconds for the flare to hit the ground.
Answer:
Step-by-step explanation:
Given that,
The diameter of a hemispherical tank= 14 feet
Radius, r = 7 feet
water
Water weighs 62.4 pounds per cubic foot.
We need to find the total weight of the water in a full tank to the nearest pound.
The volume of the hemisphere is given by :
If water weighs 62.4 pounds per cubic foot, it means
So, the total weight of the water is .
