Answer:
x = 12
Step-by-step explanation:
18:24 (comparing the same sides for the similar shapes; 18 and 24) when simplified down is equal to 3:4.
Using this 3:4 scale factor we can find the missing side x.
Solving for x :
× 16 = 12
x = 12
OR: Set up a proportion:
×
<em>cross-multiply</em>
16 × 18 = 288
24 × x = 24x
288 = 24x
x = 12

Step-by-step explanation:
Hello,
To know the height of the baseball when it is hit we have to compute h(0), as t = 0 is when the baseball is hit into the air.
So, the answer is <u>2 feet.</u>
<u />
h(x) is a parabola which can be written as , it means that the vertex is the point (-b/2a,h(-b/2a)).
The baseball reached its maximum height after
And the maximum height of the baseball is h(4).
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
