If at least two sides and one angle of two triangles are similar, then the triangles are congruent.

What in mathematics is the congruent?

Use the Third Angles Theorem for  two figures are congruent.

When two of a triangle's angles match up with two of another triangle's angles, the third angle must likewise match up.

Answer:

Below in bold.

Step-by-step explanation:

P(x) = -0.3x² + 75x - 2000

Convert this to vertex form:

p(x) = -0.3(x^2 - 250)^2 - 2000

      = -0.3[(x - 125)^2 - 125^2] - 2000

      = -0.3[(x - 125)^2 - 15625] - 2000

      = -0.3(x - 125)^2 + 4687.5 - 2000

      = -0.3(x - 125)^2 + 2687.5

2687.5 is the maximum value of the profit.

1.  This corresponds to a selling price of $125 for the stands.

2.  Maximum profit is $2687.5.

3.  At the breaking points P(x) = 0:

-0.3(x - 125)^2 + 2687.5 = 0

(x - 125)^2 = 2687.5 / -0.3 = 8958.33

x - 125 = +/- sqrt( 8958.33)

x = 125 +/- sqrt( 8958.33)

x = 30.352, 219.648,

So, the breaking even points are $30.35 and $219.65 to nearest cent.

The possible number of ways of selection by using combination formula is 3060.

What is combination?

A grouping of items where the order in which they were chosen is irrelevant is known as combination.

Given that the number of people in the group is 18. Only 4 people will be member of the council.

The formula of combination is [tex]^{n}C_{r}=\frac{n!}{r!(n-r)!}[/tex] , where r number of objects are selected from n objects.

In the given question the value of n is 18 and the value of r is 2.

Substitute the value of n and r in [tex]^{n}C_{r}=\frac{n!}{r!(n-r)!}[/tex].

[tex]^{18}C_{4}=\frac{18!}{4!(18-4)!}[/tex]

Solve the above expression:

18^C_4 = 18x17x16x15x14/4x14

18^C_4 = 18x17x16x15/4x3x2x1

3060 18^C_4 = 3060

As per the given three coordinate of the triangle, the area of the triangle is 9.5 square units.

Area of triangle:

In the triangle ABC as with vertices or coordinates are A(x1, y1), B(x2, y2), and C(x3, y3), has the area,

Area(ΔABC) = (1/2){x1(y2 − y3) + x2(y3 − y1) + x3(y1 − y2)}

As the area is always positive.

Given,

Here we have the triangle VWX,

And their coordinates are V (-9,-7), W(-4,-5), and X(-6,-2).

Now we have to find the area of the triangle.

To find the area of the triangle, let us consider the coordinates (x1,y1) as v(-9,-7), (x2,y2) as W(-4,-5) and (x3,y3) as X(-6,-2).

Now, we have to apply the values on the formula, in order to get the area of the triangle,

=> A = 1/2 |(-9 [-5-(-2)] + (-4)[-2 - (-7)] + (-6)[-7 - (-5)]|

When we expand the terms, then we get,

=> A = 1/2 |(-9)[-3] + (-4)[5] + (-6)[-2]|

Further simplify the expression will gives you the following,

=> A = 1/2 |27 - 20 + 12|

=> A = 1/2 |19|

Therefore, the area of the triangle is 9.5 square units.

The ROC essentially specifies the parameters under which the system's impulse response, h(n), will converge.

When applying the z-transform on the sequence h, the ROC concept is applied to the function H(z) (n). The ROC essentially specifies the parameters under which the system's impulse response, h(n), will converge. Neither X(z), the input, nor Y(z), the output, are involved in the ROC.

The region (regions) where the z-transform converges is known as the region of convergence (ROC). We can uniquely determine the inverse z-transform thanks to ROC. Let's first think about some examples. The unit sample δ(n)has z-transform 1 , hence ROC exists all the z plane .

The length and the width of the rectangle are 14 and 15 meters, respectively

From the question, the statement is given as

Length and width are consecutive integers

Where

Area = 210 square feet

Represent the dimensions with x and y

Where Length = x and Width = y

And also, we have

y = x + 1

The area of a rectangle is

Area = Length x width

Mathematically, this can be represented as

Area = x * y

So, we have

x * y = 210

Substitute y = x + 1 in x * y = 210

x * (x + 1) = 210

Express 210 as 14 * 15

x * (x + 1) = 14 * 15

This means that

x = 14

Substitute x = 14 in y = x + 1

y = 14 + 1

Evaluate

y = 15

So, we have

x = 14 and y = 15

Hence, the length and the width are 14 and 15 meters

Using the midpoint, the coordinates of point Y in the line segment TY is (-18, -9).

Point T is located at (2, 5). Point A is located at (-3, 1.5). Point A is the midpoint of segment TB.

Therefore, the mid point formula can be represented as follows:

(xₙ, yₙ) = (x₁ + x₂ / 2, y₁ + y₂ / 2)

Hence, let's find the coordinates of point B.

(-3, 1.5) = (2 + x₂ / 2 ,  5 + y₂ / 2)

2 + x₂ / 2  = - 3

cross multiply

2 + x₂ = -6

x₂ = -6 -2

x₂ = - 8

1.5 = 5 + y₂ / 2

3 = 5 + y₂

y₂ = 3 - 5

y₂ = -2

Therefore, the coordinates of B is (-8, -2)

Hence, let's find the coordinate of point Y. The coordinates of point B is the mid point of segment TY.

(-8, -2) = (2 + x₂ / 2 ,  5 + y₂ / 2)

(-8, -2) = (2 + x₂ / 2 ,  5 + y₂ / 2)

2 + x₂ / 2 = - 8

-16 = 2 + x₂

x₂ = -18

-2  =  5 + y₂ / 2

-4 = 5 + y₂

-4 - 5 = y₂

y₂ = -9

Therefore, the coordinates of y is (-18, -9)

Point 2 → (5, -2.4)

Find: the equation of the line and its graph

Solution:

To help us determine the equation of the line passing through the given points, let's use the Two-Point Form formula.

Let's plug into the formula above the coordinates of the two points.

Then, solve.

Multiply -3/10 by the terms inside the parenthesis.

Add 0.6 on both sides of the equation.

Hence, the equation of the line passing through the given points in slope-intercept form is y = -0.3x - 0.9.

In the equation, the slope is -3/10 while the y-intercept is -0.9.

Since the slope is negative, the line must be leaning to the left. Since the y-intercept is -0.9, the line must cross the y-axis or the vertical line at -0.9. Hence, the graph of the equation is:

The given  polynomial function f(x)=x^3 - 2x^2 - 5x + 6 as a product of linear factors as (x+2).(x-3).(x-1)

In the above question, a polynomial function is given

f(x)=x^3 - 2x^2 - 5x + 6

However, we know that, zero of a polynomial means all the x-values that bring a polynomial, p(x), to zero are referred to as its zeros, which means putting any value of x in the function we should get value of f(x) as zero

And, in the question, it is given as

f(0)=6, f(2) = -4, f(-2) = 0, f(3) = 0 , f(-1) = 8 , f(1) =0

We can clearly see that,  f(-2) = 0, f(3) = 0, f(1) =0

=> (x+2), (x-3), (x-1) are the linear factors of the given polynomial

Hence, we can write the given  polynomial function f(x)=x^3 - 2x^2 - 5x + 6 as a product of linear factors as (x+2).(x-3).(x-1)

T is the total charges,

m is the number of months of storage

Given

T = $260.00

we are to find the value of m
