Answer: House = 550 and Porch = 325

Explanation:

Porch = (30 x 15) - [(30 + 20)5/2]
Porch = 450 - 125
Porch = 325

House = (30 x 10) + 2(125)
House = 300 + 250 = 550

Use the given information to find the unknown value:y varies inversely with a. When x = 4, then y= 4. Find y when I = 2.Iyy =hel

Mashutka [201]

Inverse variation:

$y=\frac{k}{x}$

k is a constant

Use the given information (when x=4 y=4) to find the value of the constant:

$\begin{gathered} 4=\frac{k}{4} \\ \\ \text{Multiply both sides of the equation by 4:} \\ 4\times4=4\times\frac{k}{4} \\ \\ 16=k \\ \\ \\ k=16 \end{gathered}$

Then, the given relationship has the next equation:

$y=\frac{16}{x}$

Use the equation above to find y when x=2:

$\begin{gathered} y=\frac{16}{2} \\ \\ y=8 \end{gathered}$ Then, when x=2, y=8

What is the General form of the parabola of (y-3)^2=6(x+8)

MatroZZZ [7]

Answer:

x = 1.5 $t^{2}$ , y = 3 + 2at.

Step-by-step explanation:

For the parabola $Y^{2}$ = 4aX ,

General form will be

(X = a $t^{2}$ , Y = 2at) ,

Thus , for the parabola $(y-3)^{2}$ = 6(x +8)

Here , a = 1.5 and Y from the above equation should be substituted by y - 3 and X must be substituted by x + 8. After substitution of the same we can use the general equation formula for this parabola also.

Thus , general equation comes out to be :-

x + 8 = 1.5 $t^{2}$ , y - 3 = 2at

x = 1.5 $t^{2}$ , y = 3 + 2at.

(Literal equations) The formula for the volume of a cylinder is V = πr^2h. Solve V = πr^2h for h, the height of the cylinder. A.

Kobotan [32]

Answer:

Step-by-step explanation:

Given

V = πr²h

Isolate h by dividing both sides by πr²

$\frac{V}{\pi r^2}$ = h → C
