Answer: It is being dilated by a scale factor of 1/3.

Step-by-step explanation:

The pre-image has the coordinates (0,0) (6,0) (6,-3) and (0,-3) and a transformation has been applied to it to get the coordinates of the image to be (0,0) (2,0) (2,-1) ( 0,-1)

Looking at the coordinates we can see that to get from 6 to 2 you will have to multiply by 1/3 and to get from -3 to -1 you will have to multiply by 1/3.

This means that pre-image was dilated by a scale factor of 1/3.

The angles of a triangle add up to 180 degrees. The second angle is 30 degrees larger than the smallest angle. The third angle i

Rudik [331]

Answer:

Step-by-step explanation:

first angle = x

second angle = x+30

third angle = 4x

x + (x+30) + 4x = 180

6x + 30 = 180

6x = 180 - 30

6x = 150

x = 150:6

x = 50

AfilCa [17]

Answer:

Part a. 1400 unit²

Part b 1240 unit²

Part c 1333.33 unit²

Step-by-step explanation:

The given function is 20·x - x²

Part a.

The dimensions of the five rectangles are;

20 × 20 + 20 × 18 + 20 × 16 + 20 × 10 + 20 × 6 = 1400 unit²

Part b.

The dimensions of the ten rectangles are;

10×20 + 10×18 + 10×16 + 10×16 + 10×14 + 10×12 + 10 × 10 + 10 × 8 + 10 × 6 + 10 ×4 = 1240 unit²

Part c.

To find the area with an infinite number of rectangles, we can use limits similar to integration;

$\int _{0}^{20}\left (20\cdot x - x^{2} \right )dx$

Which gives;

$\int _{0}^{20}\left (20\cdot x - x^{2} \right )dx = \left [\dfrac{20}{2}\cdot x^{2} - \dfrac{x^{3}}{3} \right ]_{0}^{20} = \left [10\cdot x^{2} - \dfrac{x^{3}}{3} \right ]_{0}^{20}$

10×20^2 - (20^3)/3 = 4000/3 = 1333.3333

Write the standard form of the equation of each line. How do I find the slope and y-intercept with the graph for problem 6???

lisov135 [29]

The standard form for an equation is y=mx+b. You find the slope by using the formula of rise over run. This means that for problem 6 you first look to see if its positive or negative slope. The slope is positive if the line is going uphill and if its going downhill its negative. The slope would be negative for number 6 because it is going downhill. Then for the actualy slope you would start with rise. So you look at the point (0,1) and go up 3 until you hit the line of the other point and run over 2. So your slope would be -3/2.

Answer:

Snowball Sampling

Step-by-step explanation:

Based on the specific scenario that is being described it can be said that the best type of sampling for you to use would be Snowball Sampling. This is a unique nonprobability sampling technique where subjects for the experiment at hand are recruited from the existing subjects list of acquaintances. Such as in this case it would target all the acquaintances of the Sting-Ray owners.
