The function of the object height is an illustration of a projectile motion
The object will never hit the ground
<h3>How to determine when the object hits the ground?</h3>
The function is given as:
h=16t^2+80t+96.
When the object hits the ground, h = 0
So, we have:
16t^2+80t+96 = 0
Divide through by 16
t^2+5t+6 = 0
Expand
t^2 + 3t + 2t + 6 = 0
Factorize
t(t + 3) + 2(t + 3) = 0
Factor out t + 3
(t + 2)(t + 3) = 0
Solve for t
t = -2 or t = -3
The time (t) cannot be negative.
Hence, the object will never hit the ground

Answer:
Inverse Function: f^-1(x) = 9/4x + 9
Step-by-step explanation:
To find the inverse function we can interchange the position of the variables x and y, and then solve for y;
y = 4/9x - 4 => x = 4/9y - 4,
x = 4/9y - 4,
4/9y = x + 4,
y = 9/4x + 9/4(4),
y = 9/4x + 9/ f^-1(x) = 9/4x + 9
Answer: He bought 6 pounds of coffee.
Step-by-step explanation:
Money he have = 70
money he used to buy = 70.00 - 23.62 = 46.38
so
7.73 dollar = 1 pound
1 dollar = 1/(7.73) = 100/773 pound
46.38 dollar = (100/773) * 46.38 = 6 pound
Answer:
Do you have the math exercices? I am sorry but I can just help in the subjects concerning math. It is been some time since I studied biology and other high-school subjects.
Answer:
$7.56
Step-by-step explanation:
They sell it in $2.25 per kg
Hamburger: cost
1 kg : 2.25
3.4 : 7.56
1 x 3.4= 3.4
so, 2.25 x 3.4= 7.56
