What is the LCD of 4x^2y and 6xy^4

Answers

4x^2y = 8x^2y         the LCM 8x^2y  & 6xy^4
                                 LCM  of  8 & 6 is      8 x 3 =24
                                 LCM  of x & x^2 =  x^2
                                 LCM of y & y^4 = y^
                                 thus the LCM is            24x^2y^4

The distance an object falls when dropped from a tower varies directly as the square of the time it falls. If the object falls 144 feet in 3 seconds, how far will it fall in 17 seconds?

Answers

Direct variation:
y=kx^2
y - the distance, x - the time

The object falls 144 feet in 3 seconds.
144=k * 3^2 \n144=9k \nk=(144)/(9) \nk=16 \n \Downarrow \n y=16x^2

The object falls y feet in 17 seconds.
y=16 * 17^2 \ny=16 * 289 \ny=4624

In 17 seconds the object will fall 4624 feet.
