The image of the triangle after the dilation with a scale factor of 2 is graphed on the image shown at the end of the answer.

A dilation happens when the coordinates of the vertices of an image are multiplied by the scale factor, changing the side lengths of a figure.

Hence, to graph the image of triangle ABC on this problem, we have to:

The coordinates of the vertices of the original triangle are given as follows:

(0,0), (-4,-2), (-4,4).

The scale factor for the dilation is is given as follows:

k = 2.

Then the coordinates of the vertices of the image of the triangle after the dilation are given as follows:

(0,0), (-8,-4), (-8,8).

The triangle with these three vertices is graphed on the image presented at the end of the answer.

According to the definition of distance, the distance between the points (10, 13) and (20, 13) is 10.

The distance between two points is equal to the length of the segment that joins them.

Given the coordinates of two different points (x₁, y₁) and (x₂,y₂), the expression that allows calculating the distance "d" between two different points on the Cartesian plane is:

d= √[(x₂ - x₁)² + (y₂ - y₁)²]

In this case, you know:

Substituting in the definition of distance:

d= √[(20 -10)² + (13 -13)²]

Solving:

d= √[10² + 0²]

d= √10²

d= √100

d= 10

Finally, the distance is 10.

The minimum unit of cost is 19446.

The function C (x) = [tex]0.5x^{2}-180x+35646[/tex].

Minimum point: The minimum point of a function can be defined as the point at which a function takes its lowest value. This point is found by equating the derivative of the function to zero and solving.

For a quadratic equation of the form

f(x)= [tex]ax^{2}+bx+c[/tex]

Minimum occur when a is positive and it occurs at x=[tex]\frac{-b}{2a}[/tex]

Here cost function quadratic with a= 0.5 , b= -180

So minimum is at

[tex]x=\frac{--180}{2*0.5}[/tex]

=180

So minimum cost is when x=180. So find C(180) to get minimum unit cost .

C(180)=[tex](0.5)*(180)^{2}-180*180+35646[/tex]

=19446

Therefore, the minimum unit of cost is 19446.

Rays and angles are related because when two rays share a common endpoint, they form an angle

An angle's measure serves as its definition; it is independent of the angle's side lengths. A ray is a segment of a line where one point is fixed and the other has no end.

The combination of two rays with the same endpoint is called an angle. The vertex of the angle is the common endpoint of the rays, which are referred to as the sides of the angle. The distance between the rays is how an angle is measured.

Pick a bunch of values of 'x' .....calculate the corresponding 'y' values then plot the ordered pairs and connect the dots with a smooth curved line ...

We can evaluate the given iterated integral to be -πcos2(x) (z - 0 ).

We start with the innermost integral: 0 √1 − z2 0 z sin(x) dy. We can simplify this expression to 0  sin(x) ( √1 − z2  - 0 ). We then integrate this expression with respect to y, yielding sin2(x).

Next, we move on to the middle integral, which is sin2(x) dz. We can easily integrate this expression with respect to z and get sin2(x) (z - 0 ).

Finally, we take the outermost integral, which is sin2(x) (z - 0 ) dx. We can integrate this expression with respect to x and get -cos2(x) (z - 0 ).

Putting everything together, we can evaluate the given iterated integral to be -πcos2(x) (z - 0 ).

Answer:

x = 15

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{MP}{XZ}[/tex] = [tex]\frac{NP}{YZ}[/tex] ( substitute values )

[tex]\frac{x+5}{30}[/tex] = [tex]\frac{4x-10}{75}[/tex] ( cross- multiply )

30(4x - 10) = 75(x + 5) ← distribute parenthesis on both sides

120x - 300 = 75x + 375 ( subtract 75x from both sides )

45x - 300 = 375 ( add 300 to both sides )

45x = 675 ( divide both sides by 45 )

x = 15

The value of cos⁻¹(1/2) on the unit circle is 60°.

A circle with a radius of one unit is referred to as a unit circle. In the Cartesian coordinate plane, the unit circle is typically depicted. The second-degree equation with the variables x and y is used to algebraically represent the unit circle.

Given:

cos⁻¹(1/2)

As we know that for the unit circle, the value of the radius is 1,

Calculate the value of cos x as shown below,

cos x = radius of the circle / √(r² + p²)

cos x = 1 / √(1² + 1²)

cos x = 1 / √2

x = cos⁻ (1 / √2)

x = 45°

Thus, cos⁻¹(1/2) = 60°

If the measure of the five angles are 140° each , then the measure of sixth angle of hexagon is 20° .

What is a Hexagon ?

The hexagon is defined as the  two dimensional closed polygon that have six sides, 6 vertices and 6 angles .

the measure of the 5 angles of hexagon is =  140° each ;

which means that the sum of measure of 5 angles is = [tex]5 \times 140[/tex] = 700° ;

and we know that the sum of all 6 angles of the hexagon is 720° ;

let the measure of the sixth angle be = x ;

So , [tex]700 + x = 720[/tex] ;

⇒ [tex]x = 720-700 = 20[/tex] .

Therefore , the measure of sixth angle is 20° .

[tex]x = \frac{1 +\sqrt{359}i }{20} , x = \frac{1 -\sqrt{359}i }{20}[/tex]

Step-by-step explanation:

Given equation is

          [tex]10x^2 - x + 9 = 0[/tex]

The standard Solution of a quadratic equation is:

         [tex]x = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}[/tex]

given a = 10, b = -1, c = 9, so

        [tex]x = \frac{1 +- \sqrt{(-1)^2 - 4*10*9} }{20}\\x = \frac{1 +- \sqrt{1 - 360} }{20}\\x = \frac{1 +- \sqrt{-359} }{20}[/tex]

So roots are:

[tex]x = \frac{1 +\sqrt{359}i }{20} , x = \frac{1 -\sqrt{359}i }{20}[/tex]

The solution is Option B.

An investment of $300 gaining compound interest at a rate of 4% can be modeled by the equation B = 300 x ( 1.04 )ⁿ , where n = t

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

Given data ,

Let the amount to be invested be represented as P

The value of P = $ 300

Let the final amount be represented as A

Let the time period be = n = t

Let the rate of interest be represented as r = 4 %

r = 4/100

The value of r = 0.04

Now , the compound interest is calculated by the equation ,

A = P ( 1 + r/n )ⁿᵇ

Substituting the values in the equation , we get

A = 300 ( 1 + 0.04 )ⁿ

On simplifying the equation , we get

A = 300 ( 1.04 )ⁿ

where n = t = number of years

Hence , the equation is 300 x 1.04^t

The expression that represents the total cost of games after w weeks is 1000w + 2000wg.

The cost, in dollars, for a video game developer to code g games can be represented by the function v(g) = 500 + 1000g. The number of games produced in w weeks is given by the function g(w) = 2w.

The expression that represents the total cost of games after w weeks can be represented as follows;

Therefore,

v(g) = 500 + 1000g

g(w) = 2w.

total cost = v(g) × g(w)

total cost = (500 + 1000g)2w

Therefore,

total cost = 1000w + 2000gw

The domain of the logarithmic function f(x)=log(x) is all real numbers x>0. The range of the logarithmic function is all real numbers y>-∞.

The domain of a logarithmic function f(x)=log(x) is all real numbers x>0. This is because the logarithm function is not defined for x ≤ 0, as log(x) is undefined for x ≤ 0.

The range of the logarithmic function is all real numbers y>-∞. This is because the logarithm of a real number is always negative and approaches negative infinity as x approaches 0. Therefore, the range of a logarithmic function is all real numbers y>-∞.
