# SAT Math: Interpreting the Values of a Parabolic Equation

Water exits from a fountain, forming a parabolic shape that can modeled by the equation above. a, b, and c are constants, h is the height of water, and tis the amount of time, in seconds, that the fountain emits water. What factor does b most closely represent?

is the height of water and T is the amount

of time in seconds that the fountain amidst water what

factor does be most closely represents Well found Sure do

look nice when they're spraying water nice and high and

there's a drought when they're empty and growing a thick

layer of moss and not so much But the water's

height is being measured as it changes over time And

since an arch of water looks the same all the

time while that must mean that this equation is tracing

the path of a few specific drops of water over

time or you know something like that well the result

of the equation is H which is the height and

well it has some type of a unit of length

right So let's just say inches because I'm just calling

them units will probably get confusing Anyway we know that

the end result of evaluating every term on the right

will have to come out to inches Since B is

being multiplied by tea which is measured in seconds time

there B must be in units of inches per second

On that way multiplying by T will cancel the seconds

out so that well just inches or left got it

makes sense So it means that the answer is B

A measure of distance is per unit Time is speed 00:01:29.7 --> [endTime] That's it Bye Blue
