6 0

Answer:

Option C. 132\ in^{2}

Step-by-step explanation:

we know that

The surface area of cylinder is equal to

SA=2\pi r^{2} +\pi Dh

we have

D=6\ in

r=6/2=3\ in

h=4\ in

substitute

SA=2\pi (3^{2}) +\pi (6*4)=42\pi\ in^{2}=132\ in^{2}

Find all values of m so that the function y = xm is a solution of the given differential equation. (Enter your answers as a comm
blagie [28]

Answer:

m = 6,9  

Step-by-step explanation:

We are given that y = x^m is a solution to given differential equation.

x^2y'' - 14xy' + 54y = 0  

First we 3evaluate the value of:

y'' = m(m-1)x^{(m-2)}

y' = mx^{(m-1)}

Putting these value in the above differential equation, we get,

x^2m(m-1)x^{(m-2)} + 14xmx^{(m-1)} + 54x^m = 0

x^m[m(m-1) -14m + 54] = 0

x^m(m^2 - 15m + 54) = 0

(m^2 - 15m + 54) = 0

(m-9)(m-6) = 0

m = 9,6

Thus, for m = 9,6 , the function y = x^m is a solution of given differential equation.

Determine the equation of the line with slope 3 that passes through the point (2, 0).
Aleonysh [2.5K]

Hello there! :)

If we are given the slope of the line and a point that the line passes through, we can write its equation in point-slope form:

y-y1=m(x-x1)

y-0=3(x-2)

y-0=3x-6

y=3x-6

Therefore, that's the equation. The right option is Option C.

I hope this helps you.

Please let me know if you have any doubts.

Good luck on your assignment.
