Answer:
I'm pretty sure its C but some please correct me if I'm wrong.
Answer:
About 23.4 feet.
Step-by-step explanation:
Pythagoreans theorem states a^2 + b^2 = c^2.
a = 8, squared = 64
b = 22, squared = 484
64 + 484 = 548
√548 = 23.4, rounded.
23.4 feet is your answer.
Hope this helps.
Answer:
250 hours
Step-by-step explanation:
The first charge is 10 hours, the second charge is 10(0.96) hours, and so on -- the total of these two is 10+10(0.96) and we need to keep adding our battery usage up until there is no more battery. The third one is 10(0.96)*(0.96), or 10(0.96)².
This can be seen as a geometric series, with 10 as the first tern, or a, and 0.96 as the common ratio, or r. The sum of this is
, with n being the number of terms. Since 0.96 to the power of n never actually reaches 0 no matter how high n goes if the number is not infinite, we can say n is infinity. As r^n is really close to 0 when n equals infinity (so close that, for our purposes in this equation, we can just assume it's 0), our equation is then
