<h3><u>Question:</u></h3>

A ball is thrown into the air with an initial velocity of 22 meters per second.

The quadratic function h(t) = -4.9t2 + 22t + 5.5 represents the height of

the ball above the ground, in meters, with respect to time t, in seconds.

Determine h(3) and explain what it represents.

<h3><u>Answer:</u></h3>

h(3) = 27.4

h(3) = 27.4 means that the ball throw into the air with an initial velocity of 22 meters per second is 27.4 meters above the ground after 3 seconds.

<h3><u>Solution:</u></h3>

The quadratic equation that represents the height of the ball above the ground, h(t), in meters, with respect to time, t, in seconds is given by:

h(t) = -4.9t^2+22t+5.5

To find h(3), substitute t = 3 into given quadratic equation and solve for it

Plug in t = 3 in h(t)

h(3) = -4.9(3)^2+22(3)+5.5\\\\\text{Simplify the above expression }\\\\h(3) = -4.9 \times 9 + 66 + 5.5\\\\h(3) = -44.1+66+5.5\\\\h(3) = 27.4

Thus h(3) = 27.4

h(3) = 27.4 means that the ball throw into the air with an initial velocity of 22 meters per second is 27.4 meters above the ground after 3 seconds.

Pls, help with this math question
Aleks04 [339]

Step-by-step explanation:

OCB=CBO(base angle of isosceles triangle are equal)

now,

OCB+CBO+BOC=180°(sum of angles of triangles)

BOC=180-62

BOC=118°

again,

x=BOC/2{inscribed angle is half of central angle standing on Same base}

x=118/2

x=59°
