Hello :
the y intercept of the graph y =√(4-x) when x=0 : y = √(4-0) = √(4) = 2
Answer:
The Answer is C. The graph of two parallel lines which do not Intersect can't have a solution as Parallel lines NEVER meet.
Answer:
<u>It takes the hose 300 hours to fill the pool</u>
<u />
Step-by-step explanation:
The hose can fill the pool at a rate of 0.5 gallons per second, which means that it can fill the pool at a rate of 1 gallon per 2 seconds. It needs to fill 9000 gallons of water, so assuming the ratio remains 1:2, it takes the hose 18000 (9000*2) seconds to fill the pool completely.
However, it is important to note that we have to answer in terms of hours. There are 60 seconds in an hour, so 18000 seconds is equal to <u>300 hours</u> (18000/60).
Answer:
25,133 m^2
Step-by-step explanation:
The lateral area of a cone is found using the slant height (s) and the radius (r) in the formula ...
A = πrs
So, we need to know the radius and the slant height.
The radius is half the diameter, so is (160 m)/2 = 80 m.
The slant height can be found using the Pythagorean theorem:
s^2 = r^2 + (60 m)^2 = (80 m)^2 +(60 m)^2 = (6400 +3600) m^2
s = √(10,000 m^2) = 100 m
Now, we can put these values into the formula to find the lateral area:
A = π(80 m)(100 m) = 8000π m^2 ≈ 25,133 m^2
16.24 ÷ 1,000 = 0.01624
Good luck! <3
