The slope of the smaller triangle is 5/4 (5 over 4)
The slope of the larger triangle is 10/8 (10 over 8)
They are equal as 10/8 can be reduced to 5/4
Answer:
????
Step-by-step explanation:
number 1 could be 2 different answers
Step-by-step explanation:
u vector components:
x-comp = 8 - (-17) = 25
x-comp = -11 - 4 = -15
Therefore, we can write vector u as
u = 25i - 15j
v = 14i - 4j
u - v = 11i - 11j
Therefore,
2(u - v) = 22i - 22j
Answer:
both fireworks will explode 4.5 seconds after Firework B launches
Step-by-step explanation:
Given;
speed of firework A,
= 360 ft/s
speed of firework B,
= 340 ft/s
If the two fireworks explodes at the same height, then the height attained by the two fireworks are equal.
let the distance traveled by each firework before explosion = d
Distance = speed x time
Distance A = Distance B
speed A x time = speed B x time
let the time both fireworks explodes after Firework B launches = t
(
) t = (
) t
360t = 340t
if firework B is launched 0.25 s before Firework A, for the time of the two fireworks to be equal since we are considering time (t) after 0.25 seconds, we will have;
360(t-0.25) = 340t
360t - 90 = 340t
360 t - 340 t = 90
20 t = 90
t = 90/20
t = 4.5 seconds
Therefore, both fireworks will explode 4.5 seconds after Firework B launches
