Answer:  x-intercept

<u>Step-by-step explanation:</u>

NOTES

1) Parabolic motion is represented by the equation:

   h(t) = -9.8t² + vt + h   (in meters per second²), v is velocity

   or

   h(t) =  -32t² + vt + h   (in feet per second²),  v is velocity

2) The x-axis is time (in seconds) & the y-axis is height (in meters or feet).

Since you want to know what time the object hit the ground, h = 0

Therefore, you are looking for the zero of the equation, which is on the x-axis, thus is the x-intercept.

Hello! The salary goes up 20% due to the promotion. His original salary was $20,000. To find out his new salary, you have to do is multiply the original price by the rate. 20,000 * 20% (0.2) is 4,000. His promotion is $4,000. Now, we add. 20,000 + 4,000 is 24,000. There.

What is the difference between a relation and function? Classify each of the following as a function, or not a function. State t
Levart [38]

Answer:

A relation is a subset of cartesian product of two non empty sets whereas A function is a type of relation in which every element of first set has one and only image in the second set.

In a relation an element of the first set can have many images in the second set whereas in a function the first element can have only one image in the second set.

The given relation is not a function as the element 1 is related to 3 different elements in the second set.

James has a piece of construction paper with a length of 9/10 feet and a width of 2/3 feet.
creativ13 [48]

Area = length x width

When you multiply fractions, multiply top number by top number and bottom number by bottom number:

9/10 x 2/3 = (9 x 2) / (10 x 3) = 18/30 this can be reduced by dividing both numbers by 6:

18/30 reduces to 3/5

Answer: 3/5 square feet
