Answer:
Y = (-5/3)x + 5
Step-by-step explanation:
Label the points
(0,5), (3,0)
Use point slope
y − y1 = m(x − x1)
(5 - 0) = m(0 - 3)
Solve
Slope: -5/3
Plug in 0 for x to find the needed b
5 = (-5/3)(0) + b
b = 5
Answer:
Step-by-step explanation:
2x²-2x=3
2x²-2x -3 = 0
note :
the discriminat of each quadratic equation : ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x = (-b±√Δ)/2a
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions
***** in this exercice : a = 2 b = -2 c = -3
Δ = (-2)² -4(2)(-3) =28
x = (2±√28)/6
Answer:
8/3 or 2 2/3
Step-by-step explanation:
<span>Step 1: find the radius
The radius is half of the diameter. So the radius is 8 because the diameter is 16.
Step 2: square the radius.
8^2 = 64
Step 3: plug into formula
pi * radius squared * height
3.14 * (64) * (1.8) = 361.728 m^3
The volume of the pool is 361. 728 meters cubed.
Step 4: Divide volume by the amount pumped out per hour
volume / amount pumped out = amount of hours
361.728/16 = 22.608 hours.
So your answer is approximately 23 hours.</span><span>
