This is not the complete question.

In this we have to truncate the decimal expansion of ^3\sqrt{15} to find the best approximation. The options are:

A) 2.4 <^3\sqrt{15} < 2.5

B) 2.46 < ^3\sqrt{15} < 2.47

C) 2.46 <^3\sqrt{15} < 2.50

D) 2.47 < ^3\sqrt{15} < 2.50

Solution: Consider the cube root of 15,

By using the calculator, we will calculate its cube root.

^3\sqrt{15}=2.4662

Now, we have to find the option which approximates it in the best way.

In option A. It is given between 2.4 and 2.5 which is not the best approximation as the decimal expansion is 2.46 is between 2.46 and 2.47.

In Option B: It is given between 2.46 and 2.47 which is the best approximation as the decimal expansion is between 2.46 and 2.47.

In Option C: It is given between 2.46 and 2.50 which is not the best approximation as the decimal expansion is 2.46 is between 2.46 and 2.47.

In Option D: It is given between 2.47 and 2.50 which is not the best approximation as the decimal expansion is 2.46 is between 2.46 and 2.47.

Hence, The decimal expansion of ^3\sqrt{15} is between 2.46 and 2.47.

So, we get 2.46 < ^3\sqrt{15} < 2.47

Therefore, Option B is the correct answer.

Someone help me please
Masteriza [31]

Answer:

(5,1)

Step-by-step explanation:

Hi there!

Midpoint = \displaystyle (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} ) where the two endpoints are (x_1,y_1) and (x_2,y_2)

Plug in the given information:

Midpoint = (5,3), Endpoint = (5,5)

(5,3)=\displaystyle (\frac{5+x_2}{2},\frac{5+y_2}{2} ) where  (x_2,y_2) is the other endpoint

Solve for x_2:

\displaystyle \frac{5+x_2}{2} =5\\\\5+x_2 =10\\x_2 =5

Solve for y_2:

\displaystyle\frac{5+y_2}{2}=3 \\\\{5+y_2}=6\\y_2=1

Therefore, the other endpoint (x_2,y_2) is (5,1).

I hope this helps!

topjm [15]
The options you gave are extremely confusing, but if you round 7.9 it is 8, and if you round $3.89 it is $4. Therefore, the best estimate would be 8•$4, or $32
