Answer:

Step-by-step explanation:

Area = 72 m^2

L = 12m

Formula

w = Area / L

Perimeter = 2L + 2W

Solution

72m^2 = 12 W      Divide both sides by 12

72/12 = 12W / 12

W = 6 m

Perimeter = 2L + 2W

Perimeter = 2*12 + 2*6

Perimeter = 24 + 12

Perimeter = 36 m

30 is the length of the hypotenuse

24 is one of the bases

a^2+b^2 = c^2

where c is the hypotenuse (longest side)

24^2 + y^2 = 30^2

576 +y^2 = 900

y^2 = 324

y= √324 = 18

y =  18

Answer:

Slope Intercept form: y = mx + b

Step-by-step explanation:

mx: the slope

b: y- intercept

To find the slope, use this formula:

y₂ - y₁ / x₂ - x₁

Add in the numbers

1 - (-5) / 0 - 2

-6/2 (or -3) = slope

Use point-slope form to find the Y- intercept

y - y₁ = m (x - x₁)

y - (-5) = -3 (x - 2)

y + 5 = -3x + 6

Subtract 5 from both sides

y = -3x + 1 ← Slope intercept form

Graph the y- intercept at 1, and go down 3 and to the right 1. Your two coordinates will be (0 , 1) and (1, -2) .

Answer:

[tex]y=-\frac{3}{2}x+12[/tex]

Step-by-step explanation:

Hi there!

We want to write the equation of a line parallel to y=[tex]-\frac{3}{2}x-1[/tex] and that passes through the point (4,6)

Parallel lines have the same slopes, but different y intercepts.

The slope of the equation [tex]y=-\frac{3}{2}x-1[/tex] is [tex]-\frac{3}{2}[/tex], since the equation is written in y=mx+b format (m is slope and b is y intercept), and [tex]-\frac{3}{2}[/tex] is in the place where m is.

It's also the slope of the line parallel to it.

So we know the slope of the new line, let's write it down:

y=[tex]-\frac{3}{2}x[/tex]+b

Let's find b, in order to complete the equation

Since the equation passes through the point (4, 6), we can use it to solve for b.

Substitute 4 as x and 6 as y into the equation:

6=[tex]-\frac{3}{2}[/tex](4)+b

Multiply

6=-6+b

Add 6 to both sides

12=b

Substitute 12 as b in the equation.

y=[tex]-\frac{3}{2}x+12[/tex]

Hope this helps!

The law of sines can't only be applied to right triangles. Therefore, it's B. False.

The Law of Sines says that in any given triangle, the ratio of any side length to the sine of its opposite angle is the same for all the three sides of the triangle.

The law of sines is used to solve any triangle, when we know two angles and one side or two angles and one included side. So, it can be used on non-right triangle and right triangle as the case may be.

The sine law states that the ratio of a triangle's side length to the sine of the opposite angle is the same for all three sides. When we are given a) two angles and one side, or b) two sides and a non-included angle, we use the sine rule.

Answer: 11

Step-by-step explanation:

This is a problem of solving word problems using systems of equations.

Let's denote 2-seat tables by x and 4-seat tables by y. Therefore, their sum will be the total number of tables, which is 28. So, x + y = 28.

Now, let's concentrate on the number of customers. It says that 'when all tables are full, there will be 90 customers in the restaurant'. Therefore if we seat 2 people on each 2-seat table(x), their total number will be 2x and if we seat 4 people on each 4-seat number(y), their total number will be 4y. Hence, 2x + 3y = 90.

Now, we have a system with two equations:

[tex]\left \{ {{x + y = 28} \atop {2x + 4y = 90}} \right.[/tex]

Multiply the first line by -4.

[tex]\left \{ {{-4x -4y = -112} \atop {2x + 4y = 90}} \right.[/tex]

Now, by adding up these two equations, we get the following:

-2x = -22

x = 11

This means that the restaurant has 11 two-seat tables.

The proportionality constant will be equal to 2.

The ratio of two proportional values at a constant value is known as the constant of proportionality. The constant (commonly abbreviated k) related sums that increase or decrease simultaneously. It is the proportion between the values y and x.

Given table is below,

The maximum area is 16200 square yards

Let the dimension be x and y.

So, the perimeter is given as:

[tex]\mathbf{P = 360}[/tex]

Because it has one additional fence, the perimeter is calculated as:

[tex]\mathbf{2x + y = 360}[/tex]

Make y the subject

[tex]\mathbf{y = 360 - 2x}[/tex]

The area is calculated as:

[tex]\mathbf{A = xy}[/tex]

Substitute [tex]\mathbf{y = 360 - 2x}[/tex]

[tex]\mathbf{A = x(360 -2x)}[/tex]

Expand

[tex]\mathbf{A = 360x -2x^2}[/tex]

Differentiate

[tex]\mathbf{A' = 360 -4x}[/tex]

Set to 0

[tex]\mathbf{360 -4x = 0}[/tex]

Rewrite as:

[tex]\mathbf{4x = 360}[/tex]

Divide both sides by 4

[tex]\mathbf{x = 90}[/tex]

Substitute 90 for x in [tex]\mathbf{A = 360x -2x^2}[/tex]

[tex]\mathbf{A = 360 \times 90 - 2 \times 90^2}[/tex]

[tex]\mathbf{A = 16200}[/tex]
