B because the 2 is in the hundredths place and then you look behind the 2 which is a 5.

If its five or more you go up and 4 or less you go down, which means that you add one to the 2 which is 3 and you get rid of anything behind the 3 that was the originally.

The 1 is in the ones place
The 6 is in the Tenths
The 2 is in the Hundredths place
The 5 is in the thousandths place
When rounding, you take the number to the right of the number to determine if you’re rounding up or down. If the number is 0,1,2,3 or 4 you round down. If it’s 5,6,7,8 or 9 you round up. In this case we round up

A certain alloy contains 5.25% copper. How much copper is there I a piece weighing 200 pounds?
kykrilka [37]
Find 5.25% of 200
remember
1% of 100=1
therefor
1% of 200=2
just remove the decimal and double it (for this special case of finding percent of 200)

5.25% of 200=5.25 times 2=10.5
answer is 10.5 pounds of copper
(the legit way is 0.0525 times 200=10.5 pound)


10.5lb is answer

What is the rationalizing factor of √3? ​
Vanyuwa [196]

Answer:

±  \sqrt{3}  \:  \: ( \sqrt{3}  \:  \: or \:  \:  -  \sqrt{3} )

Step-by-step explanation:

\sqrt{3}  \times  \sqrt{3}  = 3 \:  \: (rationalize)

\sqrt{3}  \times ( -  \sqrt{3} ) =  - 3

The rationalizing factor of \sqrt{ 3}

is \boxed{\green{\sqrt{3}  \:  \: or \:  \:  -  \sqrt{3}}}

The height of a small rise in a roller coaster track is modeled by () = −. + . + . , where x is the distance in feet from a supp
Reika [66]

Answer:

Maximum height is 7 feet

Step-by-step explanation:

Solution:-

- The complete question is as follows:

" The height of a small rise in a roller coaster track is modeled by f(x) = –0.07x^2 + 0.42x + 6.37, where x is the distance in feet from a supported at ground level.

Find the greatest height of the rise "

- To find any turning points ( minimum or maximum ) points of a trajectory expressed as function of independent parameter, we find the critical points of the trajectory where the first derivative of the dependent variable w.rt independent variable is set to zero.

- In our case the height of the roller coaster track (y) is function of the distance (x) from a supported pole at ground level.

                    f(x) = –0.07x^2 + 0.42x + 6.37

- Now set the first derivative equal to zero, and determine the critical values of x:

                    0 =  -0.14x + 0.42

                    x = 0.42 / 0.14 = 3 ft

- The critical value for the coaster track is at point 3 feet away from the supported pole at ground level. So the height f(x) at x = 3 ft, would be:

                    f ( x = 3 ) = max height

                    max height =  –0.07*3^2 + 0.42*3 + 6.37

                                        = 7 ft
