Answer:
C. 40.5 cm²
Step-by-step explanation:
Use the formula for the area of a trapezoid:
A = (1/2)(b1 +b2)h
The bases are the parallel sides, 4.5 cm and 9 cm. The height is the perpendicular distance between them, 6 cm. Filling in these numbers, we have ...
A = (1/2)(4.5 +9)(6) = 40.5 . . . cm²
Answer:
The object will hit the ground after 9 seconds.
Step-by-step explanation:
We are given the function:
Where <em>h</em> is the height of the object after time <em>t</em>, <em>v</em>₀ is the initial velocity, and <em>h₀</em> is the initial height.
An object is thrown upwards from a height of 720 feet and an initial velocity of 64ft/s. We can to determine how long it will take for the object to reach the ground.
Hence, <em>h₀ </em>= 720 and <em>v₀</em> = 64. Substitute:
When the object reaches the ground, its height <em>h</em> above the ground will be zero. In other words:
Solve for <em>t: </em>

<em />
Since time cannot be negative, we can ignore the first solution.
In conclusion, the object will hit the ground after 9 seconds.
Answer:
1 13/15 yards
Step-by-step explanation:
2*3 = 6
6+ 2 = 8
8/3 * 5 = 40/15
4/5 * 3 = 12/15
40-12 = 28
28/15 = 1 13/15
There was a son a dad and his dad. I know this is confusing but there is a son who has a dad and his dad is there as well. So the dad's dad would be the littlest one's grand-dad
