Need ! 30 ! (also explain )
a ball was thrown with an initial upward velocity of 80 feet per second from an initial height of 4 feet. write an equation for h, the height of the ball in feet, t seconds after it was thrown.

80x^ + 4t + t

Yah I think that’s the answer

S=ut +0.5gt^2

s+4=80t -.5*9.81t^2

I believe

Using the equation of motion, you add 4 because it’s already at a height of 4, it’s negative gravity because it’s going against gravity.

S=80t-0.5gt^2 -4 final answer

don't report but were is the digram

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
