The correct answer to that equation is 3328
Zeros of this function
- x²-x-6=0
- x²-3x+2x-6=0
- x(x-3)+2(x-3)=0
- (x+2)(x-3)=0
- x={-2,3}
ZEros of reciprocal function
The equation
- x²-(-1/2+1/3)x-(1/2)(1/3)=0
- x²-1/6x-1/6=0
Answer:
C.
2 must be less than x if x is greater than 2, and x must be less than 4 if 4 is greater than x.
5.3 minutes.
First, let's calculate the volume of the tank. That will be the area of the base multiplied by it's length. And since it's base is a circle, the area is pi*r^2. So:
V = l*pi*r^2
V = 3.5 * pi * (2.2/2)^2
V = 3.5 * pi * (1.1)^2
V = 3.5 * pi * 1.21
V = 4.235 * pi
V = 13.30464489
So the tank has a volume of about 13.3 ft^3. Now simply divide that volume
by the rate of incoming fluid. So
13.3 / 2.5 = 5.32
Rounding to 2 significant figures gives a time of 5.3 minutes.
We know that
3 3/8-------------> (3*8+3)/8-----------> 27/8 yd
if 1 dress take---------------> 27/8 yd
X-----------------------------> 3375 yd
X=3375/(27/8)---------> x=1000 dresses
the answer is
He can make 1000 dresses
