ANSWER:D

Explained:
When in form y=mx+c , the c is the y intercept

Y^2=-x^2 +64
Y=-x + 8

For circle to cut x axis y must = 0
So Y=-x+8 becomes...
0=-x+8 |minus 8 from both sides
-8=-x
So x=8

First move the decimal point over to the left twice.

.375

Then multiply 80 by .375 like this :

.375 x 80 = 30

Lastly, add 30 to 80 and put the dollar sign.

Solve R=D-T/3 for the variable D
Ksivusya [100]

Answer:

D = \frac{3R+T}{3}

Step-by-step explanation:

given R = \frac{D-T}{3}

multiply all terms on both sides to eliminate the fraction

3R = 3D - T ( add T to both sides )

3R + T = 3D ( divide both sides by 3 )

D = \frac{3R+T}{3}

A container manufacturing company was contracted to design and manufacture cylindrical cans for fruit juice. The volume of each
gtnhenbr [62]

The volume of the cylinder is the amount of fruit juice it can contain.

The relationship between the volume and the surface area is:

\mathbf{A = \pi (\sqrt[3]{\frac{V}{2\pi}})^2 + \frac{0.946}{(\sqrt[3]{\frac{V}{2\pi}})}}

The given parameter is:

\mathbf{V = 0.946}

The volume of a cylinder is calculated as:

\mathbf{V = \pi r^2 h}

Make h the subject

\mathbf{h = \frac{V}{ \pi r^2}}

The surface area (A) of a cylinder is:

\mathbf{A = \pi r^2 + \pi rh}

Substitute \mathbf{h = \frac{V}{ \pi r^2}}

\mathbf{A = \pi r^2 + \pi r \times \frac{V}{\pi r^2}}

\mathbf{A = \pi r^2 + \frac{V}{r}}

Differentiate

\mathbf{A' = 2\pi r - Vr^{-2}}

Set to 0

\mathbf{2\pi r - Vr^{-2} = 0}

Rewrite as:

\mathbf{ 2\pi r = Vr^{-2}}

Multiply through by r^2

\mathbf{ 2\pi r^3 = V}

Solve for r

\mathbf{r = \sqrt[3]{\frac{V}{2\pi}}}

\mathbf{A = \pi r^2 + \frac{0.946}{r}}

So, we have:

\mathbf{A = \pi (\sqrt[3]{\frac{V}{2\pi}})^2 + \frac{0.946}{(\sqrt[3]{\frac{V}{2\pi}})}}

Hence, the relationship between the volume and the surface area is:

\mathbf{A = \pi (\sqrt[3]{\frac{V}{2\pi}})^2 + \frac{0.946}{(\sqrt[3]{\frac{V}{2\pi}})}}

A car dealership manager has determined that the profit, in thousands of dollars, of the dealership can be determined by the exp
ss7ja [257]

Answer:

The number of cars that brings the same profit is 9 and 0

Step-by-step explanation:

Given

x^2 - 4x = 5x

Required

Determine the possible values of x

x^2 - 4x = 5x

Subtract 5x from both sides

x^2 - 4x - 5x = 5x - 5x

x^2 - 9x = 0

Factorize

x(x - 9)= 0

Split the equation

x = 0         or        x - 9 = 0

x = 0         or        x = 9

<em>Hence, the number of cars that brings the same profit is 9 and 0</em>
