Answer:
0.000000049.
Step-by-step explanation:
This will have 7 zeros after the decimal point followed by 49:
4.9 × 10^–8 = 0.000000049.
If we imagine the decimal point making jumps to the right over the digits it takes 8 jumps till it gets to 4.9. that's where the -8 comes in.
I think 30c+3d would be the correct answer.
You are correct with the 1.42 but wrong with the 10^5
Count the digits after the 1, which is 7. So it should be
1.42 x 10^7
Given: C(N) = 15,000 + 8000N <span>
In the above equation simply substitute:
N(t) = 100t - 5t^2
for N
</span>
<span>Therefore:
C(t) = 15,000 + 8000{ 100t-5t^2 }
C(t) =15,000 + 800,000t - 40,000t^2.</span>
at t = 5
C(5) = 15,000 + 800,000*5
- 40,000*(5)^2
<span>C(5) = 3,015,000</span>
it would be 2(2^5), which is two times two to the fifth power. you take the original size and double it for every minute, which is like squaring it, but to the power of five, because it doubles once every minute for five minutes. i hope this makes sense!:)
