<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:
To find h(3), substitute t = 3 into given quadratic equation and solve for it
Plug in t = 3 in h(t)
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.
Answer:
What's the question? That seems correct if u want someone to check ur work :D
Step-by-step explanation:
2. Tom's brother saw Muscle Fitness, which offers $20 off of the $80 fee. Membership is $15 a month plus another $5 a month.
First, solve the one time fee
$80 - 20 = $60
Next, solve the monthly fee
15 + 5 = 20
(a) The expression: Let x = month
20x + 60
(b) Remember the previous question.
<em>Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month. </em>
<em>(a) Write a expression to represent the membership cost of Platinum Gym for x months.</em>
<em>Let x = months</em>
<em>20x + 60</em><em> is your expression</em>
No. In fact, it will be the same. Waiving the $20 off the one-time fee would give the same amount of one-time payment, 60. Membership and Mandatory equipment maintenance would also add up to $20 a month.
