Answer:
125
Step-by-step explanation:
f(1)= the first time (32,000)
n= 9
r= .5 (each term is being mulitplied by .5 to get the next one
We have
32,000*(.5)^(9-1)
32,000*(.5)^8
=125
9x squared - 6x - 6x + 4
9x squared - 12x + 4
The answer is 96 min, here is why:
x / 240 + x / 160 = 1
<span>2x + 3x = 480 </span>
<span>5x = 480 </span>
<span>x = 96 min
(</span><span>Drainage rate of first pipe = 480000/240 = 2000 l/min </span>
<span>Drainage rate of second tube = 480000/160 = 3000 l/min </span>
<span>Combined drainage rate = 5000 l/min </span>
<span>Time to drain = 480000/5000 = 96 min. )</span>
C; On this line, any two values have to add to 2.
Answer:
The point-slope form of the equation is:
Step-by-step explanation:
Given
We know the point-slope form of the line equation is
where m is the slope
substituting the values m = -3 and the point (3, -5)
Thus, the point-slope form of the equation is:
