The term that changes the size of a figure is called Dilation

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. A description of a dilation includes the scale factor and the center of the dilation. A dilation stretches or shrinks the original figure. Remember that to dilate something in the coordinate plane, multiply each coordinate by the scale factor

The term for a transformation that changes the size of a figure is dilation. Dilation involves stretching or shrinking a figure while maintaining its shape, using a scale factor greater than 1 for enlargement or between 0 and 1 for reduction.

The term for a transformation that changes the size of a figure is dilation.

Dilation is a geometric transformation that alters the size of a figure while keeping its shape intact. It involves stretching or shrinking the figure by a scale factor, which can either be greater than 1 (resulting in an enlargement) or between 0 and 1 (resulting in a reduction). In a dilation, all points of the original figure move away from or toward a fixed center called the "center of dilation," and their distances from the center are multiplied by the scale factor.

In contrast, other transformations have different effects:

Rotation involves turning a figure about a fixed point.

Reflection flips a figure over a line, creating a mirror image.

Translation shifts a figure in a specific direction without altering its size or shape.

So, the transformation that changes the size of a figure is dilation.

1 and 2 are adjacent angles. (C)

Answer:

vertex, (4, –2); y-intercept, –6

Step-by-step explanation:

The equation is written in vertex form [tex]y = a(x-h)^2 + k[/tex] where the vertex is (h,k).

The vertex here is (4, -2). This means the solution is vertex, (4, –2); y-intercept, –6.

Answer:

vertex, (4, –2); y-intercept, –6.

Step-by-step explanation:

[tex]y=-0.25(x-4)^{2}-2[/tex]

[tex]y=-0.25(x^{2}-8x+16)-2[/tex]

[tex]y=-0.25x^{2}+2x-4-2[/tex]

[tex]y=-0.25x^{2}+2x-6[/tex]

the vertex is [tex](\frac{-b}{2a},y(\frac{-b}{2a}) )[/tex] where a=-0.25 and b=2. So,

[tex]\frac{-b}{2a}= \frac{-2}{-0.5}=4[/tex]

[tex]y(\frac{-b}{2a})=-0.25(4)^{2}+2(4)-6= -4+8-6=-2 [/tex]

Then, the vertex is (4,-2) and the intercept is y(0)= -0.25(0)+2(0)-6 = -6. So, the answer is the third option.

Farid is renting the car for 5 additional days.

Farid wants to rent the car for 5 additional days.

Let's define the costs of the two specials and determine when they are equivalent. Let x represent the number of additional days Farid wants to rent the car.

For the first special, the cost is $40 for the first day and $2 for each additional day:

For the second special, the cost is $25 for the first day and $5 for each additional day:

We need to find the value of x where both costs are equal:

Subtract 2x from both sides:

Subtract 25 from both sides:

Divide both sides by 3:

Thus, Farid wants to rent the car for 5 additional days.

Answer:

22

Step-by-step explanation:

Divide the area (in square units) by Pi (approximately 3.14159).

Example: 380.13/3.14 = 121.06

Then square the answer.

121.06 squared = 11.0

That answer is the radius, double that to get the diameter.

11.0 * 2 = 22

Final answer:

To calculate the diameter of a circle with an area of 380.13 m², solve for the radius using the formula r = √(A/π) and then double that value to find the diameter, resulting in a diameter of approximately 22.00 meters.

Explanation:

To find the diameter of a circle with a given area, we start with the formula for the area of a circle, which is A = πr², where A is the area, π (Pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. Given the area A = 380.13 m², we can solve for the radius r by rearranging the area formula to r = √(A/π) and then calculating the diameter D by doubling the radius (D = 2r).

Step 1: Calculate the radius.
r = √(A/π) = √(380.13 m² / 3.14159) ≈ 11.00m

Step 2: Calculate the diameter.
D = 2r = 2 × 11.00m = 22.00m

The main disadvantage of home-ownership is that the individual is responsible for all maintenance and repair costs. As for the borrower's upfront payment and the amount in line 8 on the Final Settlement Statement, these would be specified in the settlement statement and cannot be precisely determined without such information.

2. The main disadvantage of purchasing and owning a home is: A. An individual assumes all responsibility for maintenance and repair of owned property. This can be expensive and time-consuming, especially if the property is older or requires frequent repairs.

3 & 4. Without the table showing the Final Settlement Statement for the purchase of a home, it would be impossible to indicate precise answers to questions 3 and 4 related to upfront cash paid by the borrower, and the amount going in line 8. These values are calculated based on several variables, which should be tabulated clearly in the Final Settlement Statement.

Answer:

Step-by-step explanation:

3x + 4y = 8

4y = 8 - 3x

y = 2 - (3/4)x

So the slope of the given line is -(3/4).

Final answer:

The slope of the line represented by the equation 3x + 4y = 8 is -3/4. We found this by rearranging the equation into slope-intercept form, y = mx + b, and identifying the coefficient of x as the slope.

Explanation:

To find the slope of the line represented by the equation 3x + 4y = 8, we first need to rearrange the equation into the slope-intercept form, which is y = mx + b, where m represents the slope of the line, and b represents the y-intercept. Let's solve for y:

The slope-intercept form of the line is y = (-3/4)x + 2, so the slope is -3/4. This means for every increase of 1 on the horizontal axis (x), there is a decrease of 3/4 on the vertical axis (y).

Answer: The answer is B - 95.

Answer: A. [tex]=105^{\circ}[/tex]

Step-by-step explanation:

Given: Circle with center O , having two congruent arcs as :-

[tex]\overarc{WX}\cong\overarc{YZ}\\\\\angle{XOW}=105^{\circ}[/tex]

We know that " If two arcs of a circle are congruent then their corresponding central angles are congruent".

[tex]\angle{XOW}\cong\angle{YOZ}\\\\\Rightarrow\ \angle{YOZ}=105^{\circ}[/tex]

Hence, the measure of [tex]\angle{YOZ}=105^{\circ}[/tex].

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

Explanation:

The variable b is the placeholder for the original price, aka price before discount.

We discount by 25% meaning we don't pay that 25% but instead pay the remaining 75%

Therefore the expression 0.75*b represents the final price after the discount. We're told this price is $1.50 so that is how I'm getting the answer to be 1.50 = 0.75b

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

Extra info:

To solve this equation for b, you would divide both sides by 0.75 to undo the multiplication that is happening.

1.50 = 0.75b

1.50/0.75 = 0.75b/0.75 .... dividing both sides by 0.75

2.00 = b

b = 2.00

So the original price before discount was $2.00; note how 25% of this is 0.25*2.00 = 0.50 which is the amount we save and the amount we have left is 2.00 - 0.50 = 1.50 which is the proper price after discount we want.

Answer:

= 624.26 m²

Step-by-step explanation:

The area of a circle is given by the formula;

A = πr² ; where r is the radius

Radius = 1/2 diameter

   = 3.14 × 14.1 ×14.1

   = 624.26 m²

Final answer:

To estimate the area of a circle with a diameter of 28.2m, calculate the radius (14.1m), then use the formula A = πr² with pi as 3.14 to get an area of approximately 624.33 m² after rounding to the nearest hundredth.

Explanation:

To estimate the area of a circle with a given diameter of 28.2m, we first need to calculate the radius, which would be half of the diameter. Thus, the radius (r) is 28.2m / 2 = 14.1m.

Next, we use the formula for the area of a circle, which is A = πr². Plugging in the numbers, we get A = (3.14)×(14.1m)².

Carrying out the multiplication, we have A = 3.14 × 198.81m² = 624.3254m². We round this result to the nearest hundredth to get 624.33 m² as the estimated area of the circle using 3.14 for pi.

the answer is :

y = -5/2x + 3/2

Answer:

Choice b is correct.y = -5/2x+3/2 is the slope intercept form of given equation.

Step-by-step explanation:

We have given the equation:

5x + 2y = 3

We have to write the equation in slope intercept form.

The general  slope intercept form of equation is :

y = mx+c

Where m = slope and c is the y-intercept.

We have given the expression:

5x + 2y = 3

2y = 3-5x

y = (3-5x)/2

y = 3/2-5/2x

y = -5/2x+3/2

y = -5/2x+3/2 is the slope intercept form of given equation.

Where m = -5/2 and y-intercept = 3/2
