A rectangle garden has a length of 12 feet. you need 36 feet of fencing to enclose the garden. what is the width of the garden ?
iren [92.7K]

Let us suppose the width is x feet

the length is given 12 feet

Perimeter of teh garden = 2( Length + width )= 2( 12+ x)

Fencing required = perimeter of garden

36 = 2( 12+x)

36 = 2*12 + 2x

36 = 24 + 2x

36-24 = 2x

12 = 2x

12/2 = x

6 = x

Width = x feet = 6 feet .Answer .

Solve y′′=sin(x) if y(0)=0 and y′(0)=5.<br><br> y(x)=?
Ksenya-84 [330]

Answer:

y(x)=6x-sin(x)

Step-by-step explanation:

Rewrite the differential equation as:

\frac{d^{2} y }{dx^{2} } =sin(x)

Integrate both sides with respect to x:

\int\ \frac{d^{2} y }{dx^{2} } dx = \int\ sin(x) dx

\frac{dy}{dx} =-cos(x)+C_1

Integrate one more time both sides with respect to x:

\int\ \frac{dy}{dx} = \int\ -cos(x)+C_1 dx

y(x)=-sin(x)+C_1x+C_2

Now that we find the solution, let's find its derivate:

y'(x)=C_1-cos(x)

Evaluating the initial conditions:

y(0)=C_1(0)+C_2-sin(0)=0\\C_2=0

y'(0)=C_1-cos(0)=5\\C_1=5+1=6

Replacing the value of the constants that we found in the differential equation solution:

y(x)=6x-sin(x)

What is the scale factor in the dilation?​
BigorU [14]
<h3>Answer: Choice D) 2 & 1/2</h3>

Work Shown:

Length of AC = 10-4 = 6 units (I'm subtracting the x coordinates)

Length of A'C' = 25-10 = 15 units

Scale factor = (A'C')/(AC) = 15/6 = 5/2 = 2.5 = 2 & 1/2

Triangle A'B'C' has side lengths that are 2 & 1/2 times longer compared to the corresponding sides of triangle ABC.
