DIA [1.3K]2 years ago
4 0

Answer:

Step-by-step explanation:

a1=90-a2

a1=90-30=60

a2 is opposite 30 and opposite angles are equal so

a2=30

The sum of the angles of a triangle are equal to 180 degrees.

a2+a3+70=180

a3+30+70=180

a3=100=180

a3=80

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
