a water balloon is tossed into the air with an upward velocity of 25 ft/s its height h(t) in ft after t seconds is given by the

Montano1993 [528]

When the height is 0 that is when it hits the ground
solve
0=-16t²+25x+3
cant factor so use quadratic formula

for
0=ax²+bx+c
$x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$

so for
0=-16t²+25t+3
a=-16
b=25
c=3
so

$x=\frac{-25+/-\sqrt{25^2-4(-16)(3)}}{2(-16)}$
$x=\frac{-25+/-\frac{625+192}}{-32}$
$x=\frac{-25+/-\frac{817}}{-32}$
it has to be a positive time

so it will hit the ground after $\frac{25+\sqrt{817}}{32}$ seconds

If an ant crawls 1 meter in 25 seconds, what is the ant’s speed?

Oduvanchick [21]

$1min=60s\to1s=\frac{1}{60}min\\\\25s=25\times\frac{1}{60}min=\frac{5}{12}min\\\\1m/25s=1m/\frac{5}{12}min=\frac{12}{5}\ m/min=2.4\ m/min$

Artist 52 [7]

No solutions beacause you have to factor out numbers for -9 but they must equal -8 when adding them.

To answer this question, we need to know what like terms are. Like terms are terms whose variables and exponents are the same. The coefficients can be different, though. In this case, the like terms are -a²b and 5a²b (because of the definition above.
