Answer:

Hey!

Your answer is C.42.4yd

Step-by-step explanation:

There are 2 ways you can work this on out...

1. Using Pythagoras Theorem...

= 30^2 + 30^2 = 1,800 (30^2=900 so you've added 2 of those to make 1,800)

= SQUARE ROOT THE ANSWER OF 1,800

\sqrt{x} 1,800= 42.42640687119285‬

TO GET A MORE PRECISE ANSWER WE ROUND IT UP TO 1 decimal place

= 42.4 yd is the diagonal length of the dance floor!!

HOPE THIS HELPS!!

Answer:

The answer to your question is the third option

Step-by-step explanation:

a)               0.023x³ + 0.4x² - 2.1x + 8.3

                 0.023(2)³ + 0.4(2)² - 2.1(2) + 8.3

                 0.023(8) + 0.4(4) - 2.1(2) + 8.3

                 0.184 + 1.6 - 4.2 + 8.3

                 10.084 - 4.2

                 5.884

b)              0.023(4)³ + 0.4(4)² - 2.1(4) + 8.3          

                 0.023(64) + 0.4(16) - 8.4 + 8.3

                 1.472 + 6.4 - 8.4 + 8.3

                 16.172 - 8.4

                7.772
