i dont get it
i cant figure it out Step-by-step explanation:
B.The graph would rise from left to right.
C.The graph would be only in the first quadrant.
D.The larger the number of minutes, the fewer calories you would burn.
where X is the time in seconds after the ball is hit. How long is the ball in the air?
(May I also get steps on how to solve these kind of questions please?)
The value of time of the ball in the air is,
⇒ 4.5 seconds
An algebraic equation with the second degree of the variable is called an Quadratic equation.
We have to given that;
The height of a ball in feet is modeled by the equation,
y = - 16x² + 72x
where, x is the time in seconds after the ball is hit.
Hence, For time of the ball in the air, we can plug y = 0 in above equation.
y = - 16x² + 72x
0 = - 16x² + 72x
Solve for x;
- 16x² + 72x = 0
- 4x (4x - 18) = 0
This gives,
4x = 18
x = 18/4
x = 4.5 seconds
Thus, The value of time of the ball in the air is,
⇒ 4.5 seconds

Please give me the answer if you know it, or help me figure it out.
Answer:
-5
Step-by-step explanation:
because -5 is the answer and it is choice 1 i didi quiz and -5 is good answer
The value of the variable "x" in expression "5x divided by 6 = 20" is 24.
To find the value of the variable "x" in the expression "5x divided by 6 = 20", we use algebraic-techniques.
To separate the variable "x," we multiply both sides of the equation by 6, the denominator of the fraction.
This cancels out the division on the left side, leaving us with 5x on the left side:
⇒ (5x divided by 6) × 6 = 20 × 6,
⇒ (5x/6) × 6 = 20 × 6,
Simplifying the equation:
⇒ 5x = 120
To solve for the variable "x," we divide both sides of equation "5x = 120" by 5:
⇒ (5x) / 5 = 120 / 5,
⇒ x = 24
Therefore, the required value of "x" is 24.
