Find the general solution of the differential equation and check the result by differentiation. (Use C for the constant of integ

tensa zangetsu [6.8K]

Answer:

$y=3t^9+C$

Step-by-step explanation:

Given: $\dfrac{dy}{dt}=27t^8$

We want to obtain the general solution of the given differential equation.

$dy=27t^8$ dt\\$Take the integral of both sides\\\int dy =\int 27t^8$ dt$\\y=\dfrac{27t^{8+1}}{8+1} +C$, (where C is the constant of integration)$\\y=\dfrac{27t^{9}}{9} +C\\\\y=3t^9+C$

The general solution of the differential equation is: $y=3t^9+C$

CHECK:

$\dfrac{d}{dt} y=\dfrac{d}{dt}(3t^9+C)=\dfrac{d}{dt}(3t^9)+\dfrac{d}{dt}(C)\\\\\text{Since derivative of a constant is zero}\\\\\dfrac{dy}{dt}=27t^{9-1}\\\dfrac{dy}{dt}=27t^8$

A photo of a painting measures 13 inches by 17 inches. The scale factor is 1/3. What size is the painting? A. 4.3 x 5.7

JulsSmile [24]

Answer:

The new size is 4.3 x 5.7

Step-by-step explanation:

The photo originally measures

13 inches x 17 inches

If we apply a scale factor of 1/3, this means that we multiply each size by one third

13 inches * (1/3) = 4.333 in

17 inches * (1/3) = 5.666 in

If we round up we get

4.3 in

5.7 in

The new size is 4.3 x 5.7
