Answer:
Forced need to stretch 1414 inches = 129830.91 pounds
Step-by-step explanation:
Force ∝ Distance
F = KD where K is constant of proportionality
K = F/D = 6060/66 = 91.818182
Hence Force needed to stretch 1414 inches =
F = 6060/66 x 1414 = 129830.91 pounds
Answer:
(a) √8
Step-by-step explanation:
You want to know the radical equivalent to 2^(3/2).
<h3>Indices</h3>
The relationship of indices to radicals is ...
![\large{\sqrt[n]{a^m}}={a^{\frac{m}{n}}](https://tex.z-dn.net/?f=%5Clarge%7B%5Csqrt%5Bn%5D%7Ba%5Em%7D%7D%3D%7Ba%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D)
<h3>Application</h3>
The given expression can be rewritten as ...
![2^{\frac{3}{2}}=\sqrt[2]{2^3}=\boxed{\sqrt[2]{8}}](https://tex.z-dn.net/?f=2%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%3D%5Csqrt%5B2%5D%7B2%5E3%7D%3D%5Cboxed%7B%5Csqrt%5B2%5D%7B8%7D%7D)

<em>Additional comment</em>
When the index of the radical is 2, it is usually left off. The radical can be simplified by removing the perfect square factor.
![\sqrt[2]{8}=\sqrt{8}=2\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B8%7D%3D%5Csqrt%7B8%7D%3D2%5Csqrt%7B2%7D)
Answer:
y = -5x + 800 where x is the time in seconds and y the height of the parachutist in feet.
Answer:
$55.42
Step-by-step explanation:
C=kD, where k is a constant.
when C=35, D=60,
35= 60k
k= 35/60= 7/12
C=7/12 D
when D= 95,
C= 7/12 (95)
C= $55.42 (nearest cent)
