Math help please! Will give 20 points!1. A football is kicked at 40 yards away from a goal post that is 10 feet high. Its path is modeled by y = -0.03x 2 + 1.6x, where x is the horizontal distance in yards traveled by the football and y is the corresponding height above the ground in feet. Does the football go over the goal post? How far above or below the goal post is the football? Use two or more complete sentences to explain your answers. (Hint: The unit conversion is built into the given function.) Vertical Motion Model The height, h, in feet of a projectile can be modeled by h = -16t 2 + vt + s where t is the time in the air in seconds, v is the initial vertical velocity, and s is the initial height in feet. 2.

What are linear equations?
Linear equations are equations that have constant average rates of change, slope or gradient
How to complete the remainder of the table for the given function rule?
From the question, the function rule is given as:
y = -2x +9
The table of values is given as:
x -4 -2 0 2 4
y 17
Next, we substitute the other values of x in the equation y = -2x +9
y = -2(-2) +9 = 13
y = -2(0) +9 = 9
y = -2(2) +9 = 5
y = -2(4) +9 = 1
So, the complete table of values is
-4 -2 0 2 4
y 17 13 9 5 1

Step-by-step explanation:
Assuming the deck is the national playing deck with 52 cards.
Your probability of getting a 3 from the entire deck is 4/52. This number is the same for 10.
To get the probability of pulling a 3 and a 10 afterwards, you must multiply these two fractions (you're expecting a lower percentage).

The percentage decrease is equal to the change in price ( the decreased amount) divided by the original amount, then multiplied by 100. We have,
Percentage decrease = %
ANSWER: 37.5%
$30 * 100 / $ 80 = 37.5%
answer: 37.5% of decrease.
