Answer:
705,000
Step-by-step explanation:
To round to the nearest thousand, you look at the number to the right of 5. If the number is 5 or higher then you round 5 up. But it is 4 so you keep 5 the same. All of the numbers after 5 are now 0. 705,000
Answer:
x = 5/2 = 2.5
Step-by-step explanation:
Given
f(x) = 3x-7
g(x) = x+2
g^(-1)(x) = f(x)
First find g^(-1)(x) = h(x)
x=h(x)+2
h(x) = x -2
h(x) = x - 2 = f(x) = 3x-7
solve for x
x-2 = 3x -7
-2 + 7 = 3x - x
2x = 5
x = 5/2
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
