Yes because 84+45 is 129 and 3(28+15) is 129
Slope is 1/2 and the y intercept is -1
Answer:
slope= 11
Step-by-step explanation:
(12,23) = (x1,y1)
(14,45) = (x2,y2)
Now,
slope(m)= (y2-y1)/(x2-x1)
=(45-23)/(14-12)
=22/2
=11
The ball will hit the ground at 0.125 seconds
<h3>
Quadratic function</h3>
The equation of the function is a quadratic function, and the function is given as:

When the ball hits the ground, the value of h is 0.
So, the equation of the function becomes

Subtract 2t from both sides of the equation

Divide both sides by -2t

Divide both sides by 8

Hence, the ball will hit the ground at 0.125 seconds
