P-&gt;q is false and p is true.<br> q is<br> a.true<br> b.false
kirill [66]

Answer:

Choice b. q has to be false.

Step-by-step explanation:

Consider the truth table of p \implies q (p implies q).

  • p is true and q is true: p \implies q would be true.
  • p is true and q is false: p \implies q would be false.
  • p is false and q is true: p \implies q would be true.
  • p is false and q is false: p \implies q would also be true.

The only combination where p \implies q is false is when p is true and q is false. Hence, the q\! here must be false.

A cannon ball is launched at 6 feet per second from the top of a platform 12 feet above the ground.
AleksAgata [21]
A.) y = ut - 1/2gt^2 + 12
y = 6t - 1/2(9.8)t^2 + 12
y = 6t - 4.9t^2 + 12

b.) The y-intercept is 12

c.) The y-intercept represent the height of the ball at time t = 0

d.) At the time the ball reaches the ground, y = 0
-4.9t^2 + 6t + 12 = 0
t = 2.29 seconds
Therefore, it took the ball 2.29 seconds to reach the ground.
