In this question, you're solving the systems of equations to find what x and y equal to.

Solve the systems of equations:

x + y = 3

x + 2y = 6

Lets make the "y" variable the same by multiplying the top equation by -2.

-2(x + y = 3)

x + 2y = 6

----------------

-2x -2y = -6

x + 2y = 6

Solve:

-x =0

x = 0

Now, we know x = 0, now plug 0 into x in one of the equations and solve:

We'll plug it into the x + y = 3 equation.

0 + y = 3

y = 3

When you're done solving, you should get:

x = 0 and y = 3

Answer:

x = 0

y = 3

Find the missing dimension of each triangle described Height: 7 in., area: 21 in2

leonid [27]

The basic dimensions of any triangle are its area, base, and height.
They're related by the area equation; the area is half of the base times the height, or:
$A=\frac{1}{2} b h$
We know the area and the height, so the missing dimension has to be the base. Let's set up an equation by substituting the values the problem gives into the area equation.
$21=\frac{1}{2} \cdot b \cdot 7$
Can you solve this equation for $b$ ?

A tank has the shape of a surface generated by revolving the parabolic segment y = x2 for 0 ≤ x ≤ 3 about the y-axis (measuremen

Darina [25.2K]

Answer:

$100\pi\int\limits^9_0 {(\sqrt y)^2(14-y)} \, dy$ ft-lbs.

Step-by-step explanation:

Given:

The shape of the tank is obtained by revolving $y=x^2$ about y axis in the interval $0\leq x\leq 3$ .

Density of the fluid in the tank, $D=100\ lbs/ft^3$

Let the initial height of the fluid be 'y' feet from the bottom.

The bottom of the tank is, $y(0)=0^2=0$

Now, the height has to be raised to a height 5 feet above the top of the tank.

The height of top of the tank is obtained by plugging in $x=3$ in the parabolic equation . This gives,

$H=3^2=9\ ft$

So, the height of top of tank is, $y(3)=H=9\ ft$

Now, 5 ft above 'H' means $H+5=9+5=14$

Therefore, the increase in height of the top surface of the fluid in the tank is given as:

$\Delta y=(14-y)$ ft

Now, area of cross section of the tank is given as:

$A(y)=\pi r^2\\r\to radius\ of\ the\ cross\ section$

Radius is the distance of a point on the parabola from the y axis. This is nothing but the x-coordinate of the point.

We have, $y=x^2$

So, $x=\sqrt y$

Therefore, radius, $r=\sqrt y$

Now, area of cross section is, $A(y)=\pi (\sqrt y)^2$

Work done in pumping the contents to 5 feet above is given as:

$W=D\int\limits^{y(3)}_{y(0)} {A(y)(\Delta y)} \, dy$

Plug in all the values. This gives,

$W=100\int\limits^9_0 {\pi (\sqrt y)^2(14-y)} \, dy\\\\W=100\pi\int\limits^9_0 { (\sqrt y)^2(14-y)} \, dy\textrm{ ft-lbs}$

Looking for the answer for the second one

FinnZ [79.3K]

Answer:

3 for the left one, and 5 on the right one.

Step-by-step explanation:

The scale factor is 2 because they are scaled from each other, meaning they have proportional side lengths. (The angles are also the same <hint for the next question>)

If the top side is 2.5, and the bottom is 5, then you divide to find the scaled factor since they correlate to each other.

If the side lengths on A is multiplied by 2, you can do that to the missing sides to find the answers.
