Jivesh is analyzing the flight of a few of his model rockets with various equations. In each equation, h is the height of the rocket in centimeters, and the rocket was fired from the ground at time t = 0, where t is measured in seconds.

For Jivesh's Model A rocket, he uses the equation h = −90t^2 + 240t. When is the height of the Model A rocket 160 centimeters? Round your answers to the nearest hundredth.

After t ≈ [] seconds, the rocket will have reached a height of 160 centimeters.

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

step-by-step explanation:

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
