Volume is defined as the space occupied by any body in the three-Dimensions. All three parameters are required for the volume like length,width and height of the cube or Cuboid

The volume of the rectangular box will be:-

V=LxWxH

V=314x712x12

So the volume of small size box will be:-

V=2682816÷310=8654.24

The area equation is:

A = (12x - 2)*(x + 8)

Which is a polynomial of degree 2, and the perimeter is:

P = 26x + 12

Remember that for a rectangle of length L and width W, the area is written as:

A = L*W

Here we know that:

L = (12x - 2)

W = (x + 8)

Then the equation for the area is:

A = (12x - 2)*(x + 8).

For a rectangle of length L and width W, the perimeter is:

P = 2*(L + W).

Replacing what we know, we get:

P = 2*(12x - 2 + x + 8) = 2*(13x + 6) = 26x + 12

The area equation is:

A = (12x - 2)*(x + 8).

Notice that this is a polynomial that is made of the product of two polynomials of degree 1, so this is a polynomial of degree 2.

The value of y that satisfies given conditions is y = - 8.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

We also know that slope(m) = (y₂ -y₁)/(x₂ - x₁).

So, lines parallel to each other have the same slope hence to find the value of y we'll equate their slopes.

∴ (3 - 9)/(4 + 4) = (y - 1)/(4 + 8).

-6/8 = (y - 1)/12.

-3/4 = (y - 1)/12.

-36/4 = y - 1.

- 9 = y - 1.

 y = - 8.

The length and width of the rectangle will be √68 and √17. Then the perimeter of the rectangle will be 2 (√17 + √68).

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

The graph is shown below.

Then the perimeter of the rectangle will be

P = 2 (length + width)

The length of the rectangle will be

L² = 2² + 8²

L² = 4 + 64

L² = 68

L = √68

The width of the rectangle will be

W² = 1² + 4²

Answer:

35%

Step-by-step explanation:

Assuming that there are no other animals in the vet other than dogs and cats, that means the total amount of animals is 21 + 39, which is 60 animals. To find the percent of cats, simply place the number of cats based on the ratio (21) over the total number of animals (60) and multiply by a 100:

21/60 = 0.35

0.35 x 100 = 35%

Hope this helps!!

Answer:

35%.

Step-by-step explanation:

Fraction that  are cats =  21 / (21+39)

= 21/60

= 100 * 21/60

The discriminant of the quadratic equation 2x + 5x2 = 1 is 24.

Use this formula

Plug in

You get 24

Answer:

24

Step-by-step explanation:

Discriminant

b² - 4ac   (when ax² + bx + c = 0)

Assuming the given equation is:   2x + 5x² = 1

Rewrite the equation so that it equals zero:

⇒ 5x² + 2x - 1 = 0

Therefore,  a = 5    b = 2    c = -1

Input these into the discriminant formula and solve:

⇒ 2² - 4(5)(-1) = 4 + 20

                      = 24

Therefore, the discriminant of the quadratice equation is 24.

The radius of the yaw mark to the nearest tenth of a foot is 11.2 ft

The minimum speed  11.1634 miles per hour.

Yaw marks are always curved. They are, initiated by a steering input. They're what's left from a tire that is still rolling but is simultaneously sliding laterally.

The formula for determining radius from a chord and middle ordinate is

[tex]r^{2}= \frac{c^{2}}{8m}+\frac{m}{2}[/tex]

To find the radius of the yaw mark, we have to use the formula

[tex]r^{2}= \frac{c^{2}}{8m}+\frac{m}{2}[/tex]

where c is the length of the chord and m is the middle ordinate

As the tires leave a yaw mark with a 31 foot chord and a middle ordinate of 3 feet.

So,

[tex]r^{2}= \frac{31^{2}}{8*3}+\frac{3}{2}[/tex]

[tex]r^{2}= 40.041 +1.5\\r^{2}=41.541[/tex]

Now to find the minimum speed, we are going to use the formula: [tex]s=\sqrt{15fr}[/tex]

where 'f' is drag factor and 'r' is the radius

drag factor is 0.2, f=0.2

and r= 41.541 ft

So, [tex]s=\sqrt{15* 0.2*41.541}\\s=\sqrt{124.623}\\s= 11.1634 mph[/tex]

The minimum speed before the brakes are applied was 11.1634 miles per hour.

Answer:

First step, find the missing angle (you will need this later on)

We know that the sum of all angles in a triangle equals to 180°, so

180° - 65° - 40° = 75° *that's your angle (next to the point L)

Now, identify each side (as shown in my drawing attached to this message)

The law of sines tells us that

(for example) the side opposite to L (highlighted in pink in the drawing) divided by the sine of the angle at the point L (in our case, 75°) creates a ratio that remains the same for the other sides.

So,  

pink side (opposite to L)/ sin 75 (angle at L) = yellow side (opposite to J)/ sin 65 (angle at J) = blue side (opposite to K)/ sin 40 (angle at K)

*Careful, since we were not given the length of one side, you cannot find actual values for each side. Although, you can use the law of sines to logically find out which length is the longest and which one is the shortest.

*Notice that the sine of the angle relates to the length of the coloured sides

Calculate the following: sin 75, sin 40, sin 65.

Once you do that, you will realize that sin 40 = to the smallest value and that sin 75 gives you the largest value.

Thus, sin 40 < sin 65< sin 75

Which corresponds to (from smallest to largest):

blue side, yellow side, pink side

*Now, write your answer in a mathematical format (using J,L,K points)

blue = JL (explanation: it connects the two points, LJ is also a valid answer)

yellow = LK

pink= JK

ANSWER: JL, LK, JK

Step-by-step explanation:

Use the Law of Sines *because you don't have a right angle triangle.
