Answer:

7 9/10

Step-by-step explanation:

First, we need to add 4 2/3 and 5 2/5.

We should begin with converting the fractions into improper fractions.

4 2/3 + 5 2/5= 14/3 + 27/5

Now, we find the common denominator

= 70/15 + 71/15

We can add:

= 141/15

And simplify. 

= 9 2/5

Finally, we subtract 1 1/2 from 9 2/5

Your answer is 7 9/10. Hope this helps!

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}

If f(x)=3^x+10x and g(x)=2x-4 find (f-g) (x) (urgent)
notka56 [123]

Answer:

(f - g)(x) = 3^{x} + 8x + 4

Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= 3^{x} + 10x - (2x - 4) ← distribute parenthesis by - 1

= 3^{x} + 10x - 2x + 4 ← collect like terms

= 3^{x} + 8x + 4
