1 over 2 equals 2 over 4 equals 4 over 8.
Hope this helps! :)
There are 5280 feet in a mile
There are 3600 seconds in an hour
to get 40 miles per hour
we multiply 40 by 5280 and divide by 3600
40 * 5280 / 3600
this gets us 58.666666...
but since they want us to round to the nearest whole number, our answer would be 59 feet per second
It’s (-8z^2 +8x +4y -2z)
Hope it helps
