Answer:
141
Step-by-step explanation:
Area of a trapezium = (a + b)
h = height
a and b = upper and and lower lengths
Area of a trapezium = (10 + 16)
= × 26
= 117
Area of a triangle = × base × height
= × 6 × 8
= × 48
= 24
Total area = Sum of the areas of both the shapes
= 117 + 24
= 141
The given equation is where h is the height, in feet, of a ball and t is the time, in seconds.
<u>Part a: The height of the ball when t = 2 seconds:</u>
The height of the ball above the ground 2 seconds after it is released can be determined by substituting t= 2 in the equation , we get;
Simplifying the terms, we get;
Thus, the height of the ball after 2 seconds is 100 feet.
<u>Part b: The height of the ball when t = 4 seconds:</u>
The height of the ball above the ground 4 seconds after it is released can be determined by substituting t = 4 in the equation , we get;
Simplifying the terms, we get;
Thus, the height of the ball after 4 seconds is 68 feet.
