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:
w=1.5 or w=13.5
Step-by-step explanation:
this is one answer:
multiply w on both sides to leave u with
4.5=3w
divide both sides by 3
1.5=w
_____________________
this is the second one if the first one is wrong:
multiply 4.5 on both sides so that the 4.5/w would leave u with just only w alone.
then 3*4.5=13.5
w=13.5
hope dis helps if not then im not dat smart enough ;?
Answer:
-45j - 9k
Step-by-step explanation:
Multiply -9 and 5j first to get -45j
Multiply -9 and k to get -9k
Answer:
The answer is below this..
Step-by-step explanation:
An exponential term with a base greater than 1 will increase at an increasing rate. If the base is less than 1 (a fraction), then it will decrease at a decreasing rate.
Any (non-zero) base to the 0 power will have a value of 1, so the function will have a y-intercept at (0, 1) if there is no multiplier (vertical scale factor) of the exponential factor. The y-intercept will be the value of the multiplier.

g(x) = (2/5)x
y-intercept at (0,1)
graph initially decreases rapidly and then decreases slowly
__________________________________________________________
d(x) = 5 (1/3)x
y-intercept at (0,5)
