A ball fell for 20 seconds at a rate of 10 feet per second. A second ball fell for 2x less seconds at a rate of speed that is x feet per second slower than the first ball.

Which of the following equations could be used to determine how far the second ball fell?

A. y = (2x^2 - 40x + 200) ft

B. y = (2x^2 - 12x + 30) ft

C. y = (-2x^2 + 200) ft

D. y = (-2x^2 + 30) ft

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w

i think the answer is b. i hope i !
