Answer:

Step-by-step explanation:

54 = 6*9

That means there are 3 threes and 1 two

54 = 2*3 * 3 * 3

There are a pair of 3s and a two and a 3 left over.

The two and the three remain under the root sigh.

One of the pair of threes comes out of the root sign.

The other one is thrown away.

sqrt(54) = 3*sqrt(6)

Answer: -2*3 sqrt6)

Answer: - 6 sqrt(6)

division equation where 13 is quotient with the dividend a whole number and a unit fraction is the divisor
lys-0071 [83]

The division equation that has a quotient of 13 is 1/1/13 = 13

<h3>How to determine the equation?</h3>

The given parameters are:

  • Quotient = 13
  • Dividend = Whole number
  • Divisor = Unit fraction i.e. 1/n where n is an integer.

A division equation is represented as:

Dividend/Divisor = Quotient

Substitute 13 for the Quotient

Dividend/Divisor = 13

Recall that:

Unit fraction = 1/n

So, we have:

Dividend/1/n = 13

Let n = 13.

So, we have:

Dividend/1/13 = 13

This gives

13 * Dividend = 13

Divide both sides by 13

Dividend = 1

So, we have:

1/1/13 = 13

Hence, the division equation is 1/1/13 = 13

Which of the following equations best models the data plotted below?
ICE Princess25 [194]
The key with these problems is to find which function has the closest y-intercept to the graph, and then try to figure out which one best approximates the slope. 
Here are our options:
<span>A. y = x + 4 
B. y = 4x + 9 
C. y = x + 18 
D. y = 3x + 22
 
Which has the closest approximation of the y-intercept? 
The y-intercept is not directly given, but we can assume it is less than 10. 
That leaves us with A and B.

Which has the closest approximation of the slope? 
The graph, on average, seems to move up about 60 and over about 15. 
Slope = rise/run = 60/15 = 4. Although the slope isn't exactly 4, it's much closer to 4 than 1, which is slope for option A.

Therefore, the answer is 
B) y= 4x + 9
