P is True (x+x does indeed = 2x)
q is False ((3x)(-2y)=-6xy)

pVq is True (TvF is True)

p->q is False (p->q) equiv ~(p^~q) equiv ~(T^~F) equiv ~(T^T) = F

p^~q is True ((T^~F) = T^T = T)

p->~q is True (T->~F)

Maria drove to a business appointment at 50mph in the morning. Her average speed on the return trip in the afternoon was 40 mph.

MakcuM [25]

Answer:

Distance to appointment point = 5 miles

Step-by-step explanation:

Let s be the distance to the appointment point,

We have Maria drove to a business appointment at 50mph in the morning.

Time taken in the morning

$t_m=\frac{s}{50}=0.02s$

Her average speed on the return trip in the afternoon was 40 mph.

Time taken in the afternoon

$t_a=\frac{s}{40}=0.025s$

Given that the return trip took 1/4hr longer because of traffic.

That is

$t_a-t_m=\frac{1}{4}hr=0.025hr$

Substituting

$t_a-t_m=0.025hr\\\\0.025s-0.02s=0.025\\\\s=5miles$

Distance to appointment point = 5 miles

On a coordinate grid, point T is at (2, −4) and point S is at (2, 6). The distance (in units) between points T and S is ______.

Rom4ik [11]

Answer:

Step-by-step explanation:

calculate the distance using the distance formula

d = √( x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (2, - 4) and (x₂, y₂ ) = (2, 6)

d = $\sqrt{(2-2)^2+(6+4)^2}$ = $\sqrt{0+100}$ = $\sqrt{100}$ = 10
