A small stone is thrown vertically upwards from a point A above the ground. At time t secs after being thrown from A, the height of the stone above the

ground is s metres. Until the stone hits the ground, s = 1.4 +19.6t- 4.9t²

(a) Write down the height of A above the ground.

(b) Find the speed with which the stone was thrown from A.

(c) Find the acceleration of the stone until it hits the ground

its definatley   this on your answer choice?

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
