Answer: Reduction, 1/5

Because the image is smaller than the pre-image, it would be a reduction. Then you would count the length of one side of the Images. The length of the pre-image is 20 and the new image is 4. Then you would make a ratio of the new image to the pre-image which is 4/20, which simplifies to 1/5.

Hope this helps!

The scale factor of the dilation will be 1/4.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The blue figure is a dilation image of the black figure.

And, The origin is the center of dilation.

Now,

Since, The blue figure is a dilation image of the black figure.

And, The origin is the center of dilation.

Here, The length of black figure = 16 units

And, The length of blue figure = 4 units

So, The scale factor of the dilation = 4/16

                                                      = 1/4

Answer:

y = x + 5          

Step-by-step explanation:

1) First, find the slope of the line [tex]x-y = 4[/tex]. We can do this by setting it up in slope-intercept form, represented by the equation [tex]y = mx + b[/tex]. Whatever [tex]m[/tex] or the coefficient of the x-term is will be the slope. Isolate y in the equation:

[tex]x-y = 4\\-y = -x+4\\y = x -4[/tex]

So, the slope of the given equation is 1. Parallel lines share the same slope, thus the slope of the new line will be 1 as well.

2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula.

Since [tex]m[/tex] is the slope, substitute 1 for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through, substitute the x and y values of (-6, -1) into those places as well. Then, isolate y in the resulting equation to put the equation in slope-intercept form and find the answer:  

[tex]y-(-1) = 1 (x-(-6))\\y + 1 = 1 (x + 6)\\y + 1 = x + 6\\y = x + 5[/tex]

Answer:

Exercise 1: The length of the unknown leg is 4 inches.

Exercise 3: The following straws can be used to construct the triangle: b) [tex]3\,in[/tex], c) [tex]4.5\,in[/tex], d) [tex]6.5\,in[/tex], e) [tex]10\,in[/tex], f) [tex]13.5\,in[/tex]

Exercise 4: Possible options of this exercise: 1) (2, 4, 5), 2) (4, 5, 6), 3) (5, 6, 10), 4) (1, 2, 11), 5) (1, 4, 11), 6) (1, 10, 11)

Step-by-step explanation:

Exercise 1:

Let suppose that triangle represented in the figure is a right triangle, the length of the missing leg is determined by Pythagorean Theorem:

[tex]y = \sqrt{l^{2}-x^{2}}[/tex] (1)

Where:

[tex]l[/tex] - Hypotenuse, in inches.

[tex]x[/tex] - Known leg, in inches.

[tex]y[/tex] - Unknown leg, in inches.

If we know that [tex]l = 11\,in[/tex] and [tex]x = 10\,in[/tex], then the length of the unknown leg is:

[tex]y = \sqrt{21}[/tex]

Since 4 is the least whole number closest to [tex]\sqrt{21}[/tex], then we conclude that the length of the unknown leg is 4 inches.

Exercise 3:

The range of possible lengths for the missing side of the triangle is represented by the following simultaneous inequality:

[tex]x + y > l > x-y[/tex] (2)

Where:

[tex]x[/tex] - Greater side, in inches.

[tex]y[/tex] - Lesser side, in inches.

[tex]l[/tex] - Missing side, in inches.

If we know that [tex]x = 8\,in[/tex] and [tex]y = 6\,in[/tex], then we have the following range of missing sides:

[tex]14\,in > l > 2\,in[/tex]

The following straws can be used to construct the triangle: b) [tex]3\,in[/tex], c) [tex]4.5\,in[/tex], d) [tex]6.5\,in[/tex], e) [tex]10\,in[/tex], f) [tex]13.5\,in[/tex]

Exercise 4:

Let check each pair to determine possible constructions by means of the inequality used in Exercise 3:

(i) [tex]x = 4\,in, y = 2\,in[/tex]

[tex]6\,in>l>2\,in[/tex]

Possible choices: 5 inches.

(ii) [tex]x = 5\,in, y = 2\,in[/tex]

[tex]7\,in > l > 3\,in[/tex]

Possible choices: 4 inches, 6 inches.

(iii) [tex]x = 6\,in, y = 2\,in[/tex]

[tex]8\,in > l > 4\,in[/tex]

Possible choices: 5 inches, 6 inches.

(iv) [tex]x = 10\,in, y = 2\,in[/tex]

[tex]12\,in > l > 8\,in[/tex]

Possible choices: None.

(v) [tex]x = 5\,in, y = 4\,in[/tex]

[tex]9\,in > l > 1\,in[/tex]

Possible choices: 2 inches, 6 inches.

(vi) [tex]x = 6\,in, y = 4\,in[/tex]

[tex]10\,in > l > 2\,in[/tex]

Possible choices: 5 inches.

(vii) [tex]x = 10\,in, y = 4\,in[/tex]

[tex]14\,in > l > 6\,in[/tex]

Possible choices: None.

(viii) [tex]x = 6\,in, y = 5\,in[/tex]

[tex]11\,in > l > 1\,in[/tex]

Possible choices: 2 inches, 4 inches, 10 inches.

(ix) [tex]x = 10\,in, y = 5\,in[/tex]

[tex]15\,in > l > 5\,in[/tex]

Possible choices: 6 inches.

(x) [tex]x = 10\,in, y = 6\,in[/tex]

[tex]16\,in > l > 4\,in[/tex]

Possible choices: 5 inches.

Possible options of this exercise: 1) (2, 4, 5), 2) (4, 5, 6), 3) (5, 6, 10), 4) (1, 2, 11), 5) (1, 4, 11), 6) (1, 10, 11)

Step-by-step explanation:

Answer:

994.88 in2

Step-by-step explanation:

Use the surface area formula SA = 4(pi)(r2) which results in SA = 4(3.14)((8.9)2) = 994.88 square inches. Because the bowl represents half a sphere, it is necessary to divide that answer by 2 to get the surface of the bowl.

If radius of a salad bowl is 8.9 inches then the surface area of the bowl is 497.44 square inches, option c is correct.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that  radius of a salad bowl is 8.9 inches.

We have to find the  surface area of the bowl

The surface area of a half-sphere is given by the formula:

SA = 2πr²

where r is the radius of the sphere.

In this case, the radius of the salad bowl is 8.9 inches.

Substituting this value into the formula, we get:

SA = 2 x 3.14 x (8.9)²

SA = 497.44 square inches

Surface area =497.44 square inches

Hence, if radius of a salad bowl is 8.9 inches then the surface area of the bowl is 497.44 square inches, option c is correct.
