Answer:
x=y+v/b
Step-by-step explanation:
So first you have y=x-v/b. You want to isolate x, so subtract x from both sides. You'll get -x+y=-v/b. Next, you're going to want to subtract y to further isolate x now that it's on the left side. Now you'll have -x=-y-v/b. But you don't want x to be negative, so you can divide both sides by -1 to make x positive. Now you'll have x=y+v/b.
B is the right answer !!!!!!
2 steering wheels manufactured each hour were defected
There were 50 steering wheels manufactured per hour
The fraction is
![\frac{2}{50}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B50%7D%20)
Divide 2, which is the numerator by 50, which is the denominator
2÷50=.04
To change any decimal into a fraction, multiply by 100
The multiply .04 by 100 to change into a percentage
.04×100=4.⇒4%
4% is the percentage of defective steering wheels
Answer:
![y = 7e^{-3t}](https://tex.z-dn.net/?f=y%20%3D%207e%5E%7B-3t%7D)
Step-by-step explanation:
![y = C_1e^{3t} + C_2e^{-3t}](https://tex.z-dn.net/?f=y%20%3D%20C_1e%5E%7B3t%7D%20%2B%20C_2e%5E%7B-3t%7D)
implies that when
,
.
![7 = C_1e^{3\times0) + C_2e^{-3\times0}](https://tex.z-dn.net/?f=7%20%3D%20C_1e%5E%7B3%5Ctimes0%29%20%2B%20C_2e%5E%7B-3%5Ctimes0%7D)
![7 = C_1+C_2](https://tex.z-dn.net/?f=7%20%3D%20C_1%2BC_2)
For the condition
, as
,
.
In the expression for
, as
, the term containing
vanishes. Hence,
![0 = C_1e^{3t}](https://tex.z-dn.net/?f=0%20%3D%20C_1e%5E%7B3t%7D)
![C_1 = 0](https://tex.z-dn.net/?f=C_1%20%3D%200)
Since ![7 = C_1+C_2](https://tex.z-dn.net/?f=7%20%3D%20C_1%2BC_2)
![7 = 0+C_2](https://tex.z-dn.net/?f=7%20%3D%200%2BC_2)
![C_2 = 7](https://tex.z-dn.net/?f=C_2%20%3D%207)
Substituting for
and
in
,
![y = 7e^{-3t}](https://tex.z-dn.net/?f=y%20%3D%207e%5E%7B-3t%7D)
