Answer:
(1/5)x-5.4=y
Step-by-step explanation:
mx+b=y
m=(1/5)
(-8,-7)=(x,y)
(1/5)(-8)+b=(-7)
-1.6+b=-7
b=-5.4
(1/5)x-5.4=y
Answer:
f = .39
Step-by-step explanation:
d (v) = 2.15 v^2 / (64.4 f)
v = 40
d = 138
substitute these in
138 = 2.15 (40)^2 / (64.4 *f)
simplify
138 = 2.15 (*1600) / (64.4 *f)
138 = 3440 / (64.4 *f)
multiply each side by 64.4f
138 * 64.4 f = 3440
8887.2 f = 3440
divide by 8887.2
8887.2 f /8887.2= 3440/8887.2
f=.38707
to the nearest hundredth
f = .39

Answer:
The answer to your question is: r = 0.1
Step-by-step explanation:
Data
P = $4500
A = $9000
t = 9 years
r = rate
Formula
![r = \sqrt[t]{\frac{A}{P}} - 1\\](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5Bt%5D%7B%5Cfrac%7BA%7D%7BP%7D%7D%20-%201%5C%5C)
Substitution
![r = \sqrt[9]{\frac{9000}{4500} - 1\\](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B9%5D%7B%5Cfrac%7B9000%7D%7B4500%7D%20-%201%5C%5C)
Simplification
![r = \sqrt[9]{2} - 1](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B9%5D%7B2%7D%20-%201)
Result
r = 1.08 - 1
r = 0.08 ≈ 0.1
