So for number one you would start with parentheses (-2 x 4) and that would get you -8 and then you would forget about the parentheses and drop everything else down and now the problem would be -8 x 3 and remember anytime you have a number by parentheses it’s multiplication and that dot by the parentheses also stands for multiplication so -8 x 3 would get you -24. You could also look at it as positive 8 x 3 and that would get you 24 and then you could just add that negative sign to the 24

Faucet one fills up \frac{1}{15} of the bathtub in one minute and faucet two fills up \frac{1}{10} of the bathtub in one minute. If both are one then they will fill up  \frac{1}{15}+ \frac{1}{10} =  \frac{5}{30} =  \frac{1}{6} So, 1/6 of the bathtub in one minute.

Answer:

  • 2 seconds
  • 72 feet

Step-by-step explanation:

The usual equation used for the vertical component of ballistic motion is ...

  h(t) = -16t² +v₀t +h₀

where v₀ is the initial upward velocity, and h₀ is the initial height. Units of distance are feet, and units of time are seconds.

Your problem statement gives ...

  v₀ = 64 ft/s

  h₀ = 8 ft

so the equation of height is ...

  h(t) = -16t² +64t +8

__

For quadratic ax² +bx +c, the axis of symmetry is x=-b/(2a). Then the axis of symmetry of the height equation is ...

  t = -64/(2(-16)) = 2

The object will reach its maximum height after 2 seconds.

The height at that time will be ...

  h(2) = -16(2²) +64(2) +8 = 72

The maximum height will be 72 feet.
