Now that you’ve created your hypotheses, it’s time to prove them. First, look at the sum of two rational numbers. Let’s say they

are two rational numbers, x and y. Because they’re rational, they can be written as a ratio of integers. Let x = a/b and y = c/d , where a, b, c, and d are integers and b and d do not equal 0. The process for finding the sum x + y in terms of a, b, c, and d is shown. Based on this sum and using the closure property of integers, what conclusion can you make about the sum of two rational numbers? Explain your answer.

One hundred rats are being trained to run through a maze and are rewarded when they run through it correctly. Once a rat success
Assoli18 [71]

Answer:

6 trials

Step-by-step explanation:

The number of rats that run the maze incorrectly after t trials ;

N(t) = 100e^-0.14t

Initial number of rats = 100

45% of rats to run the maze incorrectly ; 45% * 100 = 45 rats

N(t) = 45

N(t) = 100e^-0.14t

45 = 100e^-0.14t

45/100 = e^-0.14t

0.45 = e^-0.14t

Take the In of both sides :

In(0.45) = In(e^-0.14t)

- 0.798507 = - 0.14t

Divide both sides by -0.14

- 0.798507 / - 0.14 = - 0.14t / - 0.14

5.7036 = t

To the nearest whole number :

Number of trials, t = 6 trials

Answer:   a) Horizontal Compression, Left 1, Up 2

<u>Step-by-step explanation:</u>

\sqrt{3x+3}+2\implies \sqrt{3(x+1)}+2\\\\\bullet \text{The 3 represents a horizontal compression by a factor of }\dfrac{1}{3}\\\\\bullet \text{The 1 under the square root represents a shift to the LEFT 1 unit}\\\\\bullet \text{The 2 outside of the square root represents a shift UP 2 unit}

Rectangle ABCD is transformed to A’B’C’D’ by a dilation. What is the scale factor used for the dilation?
jekas [21]

Answer:

Scale factor = 3

Step-by-step explanation:

Scale factor used for the dilation = the ratio of the corresponding side length of the new figure to the side length of the original figure

Scale factor = B'C'/BC

B'C' = 9 units

BC = 3 units

Scale factor = 9/3 = 3
