3.14 * r^2 * h
Step-by-step explanation:
Here are the two examples of
poorly worded questions that are biased toward each response:
<span>1.
</span>It’s
certain that keeping U.S. troops in Iraq is a good decision; we should send
more troops there, right?
<span>2.
</span><span>Since
keeping U.S. troops should not be kept in Iraq when do you think is the best
time to evacuate them?</span>
Well 1 is in the ones place so its 1
.848 is 848 thousandths so it would be 1
Answer:
Step-by-step explanation:
This is our quadratic:

where s(t) is the position of the object after all the stuff on the right side happens to it. If the object lands on the ground after all that stuff happens to it, its height is 0. Subbing in a 0 for s(t) gives us:

and if the object hits the ground at 21 seconds, we can sub in a 21 for each t to get this:
and do the math.
and solving for the height:
h = 1845.9 meters
c=52, a=2b+8
<span>
Pythagorean Theorem = a^2+b^2=c^2</span>
<span>
(2b+8)^2+b^2=52^2</span>
<span>
<span>
4b^2+32b+64+b^2=2704</span></span>
<span><span>
5b^2+32b-2640=0 </span></span>
<span>
b=20 </span>
a= 2(20)+8 =
48
<span>48+20+52
= 120</span>
