A ball is dropped from the ground. T represents the time in seconds. To find the time you can you the equation Y= -16t^2 +44t. H

bagirrra123 [75]

Answer:

2.75 seconds.

Step-by-step explanation:

We have been given that a ball is dropped from the ground. T represents the time in seconds.

To find the time when the ball was in air, we will equate height of ball with 0 and solve for t.

$-16t^2+44t=0$

Upon dividing both sides by 4, we will get:

$-4t^2+11t=0$

$-t(4t-11)=0$

$-t=0\text{ (or) }(4t-11)=0$

$t=0\text{ (or) }4t-11=0$

$t=0\text{ (or) }4t=11$

$t=0\text{ (or) }t=\frac{11}{4}$

$t=0\text{ (or) }t=2.75$

Since our given function is a downward opening parabola, so ball will be in air between both t-intercepts.

Since the ball touches the ground at 2.75 seconds, therefore, the ball would be in air for approximately 2.75 seconds.

Evaluate 2x2 − 5y when x = -3 and y = 4.

KiRa [710]

2(-3)2 -5(4). -12 -20= -32. It's this because you plug -3 and 4 into x and y. Then if you answer it out it equals -32

"If a = − 9 and b = − 6, show that (a−b) ≠ (b−a)."

denis-greek [22]

Answer:

Step-by-step explanation:

LHS a - b = -9 - (-6) = -9 +6 = -3

RHS b-a = -6 - (- 9) = -6 +9 = 3

as LHS not equal to RHS

a-b not equal to b-a

Thus proven
