$1.98 divided by 2 is $0.99
So the sale price is $0.99
Answer:
(a) D(t)= -4.9 t^2 + vt
(b) 10 sec
(c) 122.5m
(d) At t= 4sec, v= 9.8m/s (upwards) and at t= 9sec, v= 39.2m/s (downwards)
(e) -24.5m
(f) -49m/s (i.e. downwards)
(g) 0
Step-by-step explanation:
(b) Time in the air = 2v/g = 10sec
(c) Maximum height =
=122.5m
(d) Velocity at any time t = v -9.8t
So, at t= 4sec, velocity = 49 – 9.8(4) =9.8m/s
at t= 9sec, velocity = 49 – 9.8(9) = -39.2m/s
(e) Average velocity =
= -24.5m
(g) the stone is thrown vertically upwards, so no horizontal distance covered.
Ok so you would plug in 18 for the x so it would be 6(18)-12 and then 6x18 is 108 and 108-12=96 so your answer is 96
Answer:
∠Z and ∠W are supplementary
Step-by-step explanation:
In the diagram given showing a special trapezoid, WX and ZY are two opposite sides that are parallel to each other.
Thus, consecutive angles would be supplementary.
Therefore, the only correct option that is true is:
∠Z and ∠W are supplementary.
The test options are incorrect as consecutive angles are not complementary and they are not in themselves congruent to each other.
