Water flows on the Amazon river near the cachoeira de Santuario waterfalls at a velocity 75 meters per second. If a low height r
zysi [14]

Answer:

7.5 MW

Step-by-step explanation:

The power generated from a falling water is a function of its height and volume. The power generated an be calculated using the formula:

Power (P) = Density(ρ) * volume flow rate(Q) * acceleration due to gravity(g) * height(h)

P = ρQgh

But Qh = Velocity(v) * volume(V).

Hence power = ρvgV

Given that ρ of water = 1000 kg/m³, v = 75 m/s, V = 10 m³, g = 10 m/s². Substituting:

P = ρvgV = 1000 * 75 * 10 * 10 = 7500000 W

P = 7.5 MW

Can anyone help me with the odd numbers on my algebra 1 homework?
WINSTONCH [101]

y =x+10

y =6x+30

substitute x+10 into the 2nd equation anywhere you see y

x+10 = 6x+30

subtract x from each side

x-x+10 = 6x-x+30

10 = 5x+30

subtract 30 from each side

10-30=5x+30-30

-20 = 5x

divide by 5 on each side

-20/5 =5x/5

-4=x

now solve for y

y=x+10

y = -4 +10

y=6

Answer: x=-4

y=6

or (-4,6)


3.  y = -3x-6

6x+5y=-30

6x+5(-3x-6) =-30

5x-15x-30=-30

-20x-30=-30

-20x=0

x=0

y = -3x-6

y=-6

Find the slope that passes through the line (9, 3) and (2, 7)
aalyn [17]

Answer:

-4 / 7

Step-by-step explanation:

m = (y2 - y1) / (x2 - x1)

m = (7 - 3) / (2 - 9)

m = 4 / -7

m = -4 / 7

OR

m = (y2 - y1) / (x2 - x1)

m = (3 - 7) / (9 - 2)

m = -4 / 7
