Surface Area = 2×(15×10 + 15×8 + 10×8) = <span>700 foot<span>2</span></span>
Tan 17 ° = H / A
<span>H = A tan 17 ° </span>
<span>H = 12,000 * 0.30573 </span>
<span>H = 3668.8 ft </span><span>
Your answer is </span>3668.8 ft (Originally 3668.76 ft)

Answer:
N = 74(1/2)^(t/2.8)
Step-by-step explanation:
The exponential function expressing a half-life relation can be written ...
amount = (initial amount) × (1/2)^(t/(half-life))
For the numbers given in this problem, this is ...
N = 74(1/2)^(t/2.8)
__
Some folks like to express these relations in the form ...
N = 74e^(-kt)
In this form, the value of k is ...
k = ln(2)/(half-life) ≈ 0.693147/2.8 ≈ 0.24755
N = 74e^(-0.24755t)
Answer:
![2^{4}*3^{3}*5](https://tex.z-dn.net/?f=2%5E%7B4%7D%2A3%5E%7B3%7D%2A5)
Step-by-step explanation:
![\frac{x^{n} }{x^{y}}=x^{n-y}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7Bn%7D%20%7D%7Bx%5E%7By%7D%7D%3Dx%5E%7Bn-y%7D)
This means that we just subtract the exponents with identical bases so
2⁷/2³=2⁴ (7-3)
3⁶/3³=3³ (6-3)
5⁸/5⁷=5 (8-7) put them together and you get the answer
