3. (6 Points). Solve the initial value problem y'-y.cosx=0, y(pi/2)=2e
Stells [14]

Answer:

y=2e^{sin(x)}

Step-by-step explanation:

Given equation can be  re written as

\frac{\mathrm{d} y}{\mathrm{d} x}-ycos(x)=0\\\frac{\mathrm{d} y}{\mathrm{d} x}=ycos(x)\\\\=> \frac{dy}{y}=cox(x)dx\\\\Integrating  \\ \int \frac{dy}{y}=\int cos(x)dx \\\\ln(y)=sin(x)+c............(i)

Now it is given that y(π/2) = 2e

Applying value in (i) we get

ln(2e) = sin(π/2) + c

=> ln(2) + ln(e) = 1+c

=> ln(2) + 1 = 1 + c

=> c = ln(2)

Thus equation (i) becomes

ln(y) = sin(x) + ln(2)

ln(y) - ln(2) = sin(x)

ln(y/2) = sin(x)

y= 2e^{sinx}

Juanita says that a scale of 1 in. : 0.4 ft is equivalent to the ratio 6 in. : 2.4 ft. Do you agree? Explain why or why not.
Umnica [9.8K]
Answer:
Agree

Explanation:
The given scale is:
1 in : 0.4 ft
We want to get the equivalent ft for 6 in, therefore all we have to do is cross multiplication as follows:
1 in : 0.4 ft
6 in : ??
equivalent ft = (6*0.4) / (1) = 2.4 ft
This means that:
6 in : 2.4 ft is equivalent to the given scale
