What is the answer for this
KonstantinChe [14]

Answer:  y=\frac{1}{30}x+1

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

You need to find slope of the line with the formula:

m=\frac{y_2-y_1}{x_2-x_1}

Pick to  points of the given line. You can choose the point (60,3) and the point (30,2).

Then, substituting into the formula:

 m=\frac{2-3}{30-60}=\frac{1}{30}

You can observe in the graph that the line intercepts the y-axis at the point (0,1), therefore "b" is:

b=1

Substituting the slope and the y-intercept found into  y=mx+b, you get the equation of this line:

 y=\frac{1}{30}x+1

Where "y" represents the Height (1,000 ft) and "x" represents the Time in seconds.

(secx)dy/dx=e^(y+sinx), please help me solve the differential equation. Thanks :)
nalin [4]
First, you must know these formula  d(e^f(x) = f'(x)e^x dx, e^a+b=e^a.e^b, and d(sinx) = cosxdx, secx = 1/ cosx

(secx)dy/dx=e^(y+sinx), implies  <span>dy/dx=cosx .e^(y+sinx), and then 
</span>dy=cosx .e^(y+sinx).dx, integdy=integ(cosx .e^(y+sinx).dx, equivalent of 
integdy=integ(cosx .e^y.e^sinx)dx, integdy=e^y.integ.(cosx e^sinx)dx, but we know that   d(e^sinx) =cosx e^sinx dx,
so integ.d(e^sinx) =integ.cosx e^sinx dx,
and e^sinx + C=integ.cosx e^sinxdx
 finally, integdy=e^y.integ.(cosx e^sinx)dx=e^2. (e^sinx) +C
the answer is 
y = e^2. (e^sinx) +C, you can check this answer to calculate dy/dx
