Answer:
31m/s
Step-by-step explanation:
Using the equation of motion
v² = u² + 2gH
H is the height of fall = 49m
g is the acceleration due to gravity = 9.8m/s²
u is the initial velocity = 0m/s
v² = 0² + 2(9.8)(49)
v² = 960.4
v = √960.4
v = 30.9m/s
v ≈ 31m/s
Hence the velocity of water at the turbine is 31m/s
Answer:
see explanation
Step-by-step explanation:
If a parallelogram then AB = DC and AD = BC
Equating AB = DC, then
3x = x + 4 ( subtract x from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Thus
AB = 3x = 3(2) = 6 and DC = x + 4 = 2 + 4 = 6 ⇒ AB = DC
Equating AD and BC, then
2y = y + 2 ( subtract y from both sides )
y = 2
Thus AD = y + 2 = 2 + 2 = 4 and BC = 2y = 2(2) = 4 ⇒ AD = BC
Since opposite sides are congruent then ABCD is a parallelogram
Answer:
Step-by-step explanation:
y = 2x - 8. slope here is 2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign.
slope 2 or 2/1.....flip it....1/2....change the sign...-1/2. so our perpendicular line will have a slope of -1/2.
y - y1 = m(x - x1)
slope(m) = -1/2
(6,3)...x1 = 6 and y1 = 3
now we sub
y - 3 = -1/2(x - 6) <==== ur equation
Answer:
below 15 times
Step-by-step explanation:
If the numbers on the spinner are 1, 2, 3, 4, 5, 6 (six numbers) the even numbers are 2, 4, 6 ( three numbers) than 3 out of 6 numbers on the spinner are even.
If Jane will spin the spinner below 30 times the is expected that less than half of the time 30/2 = 15 times will be an even number.
