1. When a cannonball is fired, the equation of its pathway can be modeled by h = -1612 + 128t.
sashaice [31]

Answer:

The maximum height of the ball is 256m

Step-by-step explanation:

Given the equation of a pathway modelled as pathway can be modeled by h = -16t² + 128t

At maximum height, the velocity of the ball is zero.

velocity = dh/dt

velocity = -32t + 128

Since v = 0 at maximum height

0 = -32t+128

32t = 128

t = 128/32

t = 4seconds

The maximum height can be gotten by substituting t = 4 into the modelled equation.

h = -16t² + 128t

h = -16(4)²+128(4)

h = -16(16)+512

h = -256+512

h = 256m

Which of the following is a solution to the equation 4x2+4x−3=0?
Readme [11.4K]

Answer:

-1.5

Step-by-step explanation:

4x² + 4x - 3 = 0

(2x + 3)(2x - 1) = 0

2x + 3 = 0  or  2x - 1 = 0

x = -3/2   or x = 1/2

Answer: -1.5
