The boundary line is solid and the area above the line is shaded making the inequality
D. y≥3x+2
Answer:
1,960 kPa
Step-by-step explanation:
The pressure difference between two places with different height can be calculated by using Bernoulli's principle. The principle can be used to find moving fluid, but since the water inside well is static we can remove the part with velocity. You also need to know the density of water, which is 1000 kg/m3. Assuming gravity unit is 9.8 m/
, the calculation will be:
P1+ ρgh1 = P2 + ρgh2
P2 - P1= ρgh2 -ρgh1
P2 - P1= (1000 kg/m3) * (9.8 m/,) * 200m - (1000 kg/m3) * (9.8m/,) * 0m
P2 - P1= 1,960,000 kg/m = 1,960 kPa
200m deep well has 1,960 kPa higher pressure
Answer:
1) (9, 75+360n)
2) (−9, 255+360n)
Step-by-step explanation:
(9, 75) is same as (9, 75 + 360)
so it would be (9, 435)
It can also be expressed as (-9, 75 + 180 degrees)
so (-9,255) degrees
In general, (9,75+360 n) for n≥0 represents half of the possible ways of representing the point : (9,75)
Some friends went to lunch and split the bill equally. If each person paid $6.75, how many people went to lunch thinking. Use a diagram or equation to explain your thinking. The total is 27$. 27 divided by 6.75 is 4. Suppose
