I think that is the answer because it says 2/5 where two rows are shaded and three more rows remain unshaded so, when you add that three and two it's altogether 5, so I think that is the answer, please check out the document I have uploaded.

Answer:

the one you are currently clicking on (you're correct :) )

Step-by-step explanation:

For the item you are currently clicking on, there are three columns--each with five rectangular sections. Each of the three columns--as we can see on the label to the left, is equal to 1. So, the five split pieces must all combine to stack up to 1. This means that 1 must be divided amongst 5 pieces, so we divide 1 by 5: 1/5.

You are trying to find the model that represents 2/5 (times 3, so it will have three rows). For the model you are clicking on, each column is showing two rectangles being there. This means that you have two sections of 1/th--or, 2/5ths present.

This means that you have the fraction of 2/5th, and you have it three times, so it represents three 2/5ths fractions, or 3 x 2/5.

(Remember, multiplication is repeated addition. So, 3 times of something means that its there 3 times, you have three 2/5ths)

Solve the equation below for x. 500 = 25e ^ (2x)

Zigmanuir [339]

Answer:

x = i π n + log(20)/2 for n element Z

Step-by-step explanation:

Solve for x:

500 = 25 e^(2 x)

500 = 25 e^(2 x) is equivalent to 25 e^(2 x) = 500:

25 e^(2 x) = 500

Divide both sides by 25:

e^(2 x) = 20

Take the natural logarithm of both sides:

2 x = 2 i π n + log(20) for n element Z

Divide both sides by 2:

Answer: x = i π n + log(20)/2 for n element Z

This function will create a parabola that opens upwards. I’m not entirely sure what I was supposed to answer. Hopefully this covered it. I’ll attach an image of the parabola in case I missed anything.
