the volume of the cylinder is d)168 units
Answer:
1) Distance=Speed*time
90=(x+1)*(x)+(2x+5)(x-1)
90=x^2+x+2x^2-2x+5x-5
3x^2+4x-95=0
2) 3x^2+4x-95=0. Using quadratic formula, we get
x=(-4±sqrt(16-4*3*(-95)<u>)</u>)/6, x=5 or - 19/5 but since x also represents time, it can't be negative.
3) Total time take she took for the journey is x+x-1=2x-1=2*5-1=9 hours
Answer:
1
Step-by-step explanation:
We need two points to find the slope
( -1,0) and ( 2,3)
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 3-0)/(2 - -1)
= (3-0) / ( 2+1)
= 3/3
= 1
The slope is 1
3, 2.91, -0.3, -0.9, -1.01,
