The coordinates of the triangle after dilation are A'(48, 72), B'(48, 144) and C'(96, 72).

Dilation is a type of transformation where the figure is enlarged or made smaller such that it preserves the shape but not size.

Every dilated image are similar figures to the original figure.

Assume that the dilation is about the origin.

When a point (x, y) is dilated with k, then new coordinates are (kx, ky).

A(4, 6) after dilation become (4 × 12, 6 × 12) = A'(48, 72)

B(4, 12) after dilation become (4 × 12, 12 × 12) = B'(48, 144)

C(8, 6) after dilation become (8 × 12, 6 × 12) = C'(96, 72)

Hence the coordinates after undergone dilation are A'(48, 72), B'(48, 144) and C'(96, 72).

The answer would be g(x) = -4|x| - 3

Step-by-step explanation:

With transformations involving translating an absolute value function down, the translation would be outside the absolute value and is negative (since we're moving the entire graph down). As the transformation occurs after the graph is already reflected, the translation will not be affected by the reflection.

The length of CE is 22. The measurement of ∠EAD = 34°.

What is a diagonal?

The diagonal is the line that runs through the centre of the figure from one corner of the square or rectangle to the opposite corner. Any square with two diagonals that are the same length.

Given that AE = 2x+2 and BD=3x+14, ∠BEC=112°.

The diagonals of a rectangle equal and bisect each other.

Thus BD = AC.....(i)

The diagonal AC bisect at E.

AE = EC = 1/2 AC

Rewrite equation:

BD = 2AE

3x+14 = 2(2x+2)

3x+14 = 4x+4

4x-3x = 14-4

x = 10

Putting x=10 in AE = EC :

EC = 2(10)+2

EC = 22

Vertical angle theorem: The Vertical opposite angles are equal.

∠AED = ∠BEC =112° (vertical opposite angles)

Consider △ADE:

Since AE = ED, thus ∠EAD = ∠EDC.

The sum all interior angle of a traingle is 180°

∠EAD + ∠EDC + ∠AED = 180°

2∠EAD + ∠AED = 180°

2∠EAD + 112° = 180°

2∠EAD  = 180° - 112°

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

f(3)=150.3815

Part B:

Percentage of the bugs are eaten

= 335/500 ×100

= 335/5

= 67%

Part C:

Percentage of the bugs are remain 33%

Part D: Number of days after there will be fewer than 40 bugs remaining at the farm.

40=500(0.67)ˣ

(0.67)ˣ =40/500

(0.67)ˣ =0.08

Take the logarithm of both sides of the equation to remove the variable from the exponent.

Exact Form: ln (0.08)/ln(0.67)

The population of the down represent by the equation  P = 53800 [tex](1-\frac{2.5}{100})^3[/tex] and the population after 3 years is 49865.

What is rate of decrease in population?

The rate of decrease calculates a decline as a percentage of the initial sum. To determine how quickly a population is dwindling or how much money is being lost on an investment, you may want to know the rate of decrease . Knowing the initial and final amounts is necessary to compute the rate of decrease.

Here the initial population of the town is [tex]P_0[/tex] = 53800.

Population shrink rate R = 2.5%

Number of years = 3.

Now using decrease in population formula then,

P = [tex]P_0(1-\frac{R}{100})^n[/tex]

=> P = 53800 [tex](1-\frac{2.5}{100})^3[/tex]

=> P = 53800(0.975×0.975×0.975)

=> P = 49865.

Hence the population of the down represent by the equation  P = 53800 [tex](1-\frac{2.5}{100})^3[/tex] and the population after 3 years is 49865.

The value of x in the quadrilateral is 23.

A quadrilateral is a polygon with 4 sides. The sum of interior angles in a quadrilateral is 360 degrees.

The sum of external angles of any polygon, irrespective of the number of sides is 360∘.

Therefore, the value of x of the quadrilateral can be found as follows:

6x + x + 16 + 3x - 1 + 5x = 360

combine like terms

6x + x + 3x + 5x + 16 - 1 = 360

15x = 360 - 15

15x = 345

divide both sides by 15

x = 345 / 15

x = 23

Properties of the algebra are as follow:

1. Associative property :

Let a, b, c be the three expressions

a. For addition:

( a + b ) + c = a + ( b + c )

b. For multiplication :

a × ( b × c ) = ( a × b ) × c

2. Distributive property:

Let a, b, c be the three expressions

For multiplication over addition:

a ( b + c ) = ab + ac

3. Identity property:

a. For addition:

a + 0 = a

b. for multiplication :

a × 1 = a

The graph is shown below.

===================================================

Explanation:

Part A)

x² is the same as x^2

The function f(x) = 10x^2-10x is the same as y = 10x^2-10x

Compare this to the template y = ax^2+bx+c to find the following

The value of 'a' is positive, which means the parabola opens upward. Furthermore, it tells us that the graph has a lowest point. There is no highest point since both parts of the parabola go upward forever.

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

Part B)

We'll use the values of 'a' and b found earlier to get...

h = -b/(2a)

h = -(-10)/(2*10)

h = 10/20

h = 0.5

The min value therefore occurs when x = 0.5, which is the x coordinate of the vertex. The vertex being (h,k)

To find the value of k, we plug x = 0.5 into the original function.

y = 10x^2-10x

y = 10(0.5)^2-10*0.5

y = -2.5

This is the smallest the output y values can get. Therefore, it is the minimum value.

The vertex is located at (h,k) = (0.5, -2.5)

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

Part C)

With any quadratic function, the domain is "set of all real numbers". We don't have to worry about things like...

And so on.

The range is [tex]\text{y} \ge -2.5[/tex] since we found y = -2.5 to be the smallest y value possible. See part B above. So either y = -2.5 or y > -2.5
