Answer:
h(t) = -16t2 + 144
h(1) = -16(12) + 144 = 128 ft
h(2) = -16(22) + 144 = 80 ft
h(2) - h(1) = 80 - 128 = -48 ft
It fell 48 ft between t = 1 and t = 2 seconds.
It reaches the ground when h(t) = 0
0 = -16t2 + 144
t = √(144/16) s = 3s
It reaches the ground 3s after being dropped.
Step-by-step explanation:
altogether there are 7 marbles in the bag.
put the marbles in fractions, so blue would be 3/7
and red would be 4/7. but becuase you need 2 of the same, you do
3/7 x 3/7 = 9/49
4/7 x 4/7 = 16/49
then add them togther
25/49
if you need it as a percentage, it is
51.020408163265%
The answer is 90,000. Just remember 5 or above, give it a shove, and for or below let it go. Because 85 has a five at the end you push it up to 90. Same thing with 85,000 or 85,001. You shove it to 90. If it was 84,000 or 84,999 you would let it go to 80,000. Hope that helped!
<h2>63.6 cm</h2><h2 />
Cut diameter in half to find radius
9/2 = 4.5
radius = 4.5
This is the formula for area of a circle:
pi * radius^2
pi * 4.5^2
20.25pi
Now find pi:
20.25 * pi = 63.6
Answer:
63.6 cm is the area
Answer:
20 square units
Step-by-step explanation:
The figure shows a triangle whose;
- Base AC is 8 units
- Height is 5 units
We are supposed to get its area;
Area of a triangle is given by the formula;
Area = 0.5×b×h
Thus;
Area = 0.5 × 8 units × 5 units
= 20 square units
Hence, the area of the figure is 20 square units
