1200÷7.5= 160
-> there is already 160 cubic ft. of water
y=20x+160
-> this is the equation
2160=20x+160
2000=20x
100=x
you need 100 cubic ft. more to finish filling the pool
Remember this: for a trig function of <span>y = A sin(Bx + C) + D
</span><span><span>amplitude is A
</span><span>period is <span>2π/B
</span></span><span>phase shift is −C/B
</span><span>vertical shift is <span>D
So the amplitude is -4, the period is </span></span></span>π and the phase shift is -3.14/2 = 1.57.
24 dollars if you times the amount of percentage using the correct ratio you should get around 24 or maybe 24.50
Number 2 is 100 cm
number 3 the height is equal to 5
NUMBER 4 b is equal to 13
