Answer:
Step-by-step explanation:
step 1
Find the volume of the old can
The volume of the can is equal to
we have
----> the radius is half the diameter
substitute
step 2
Find the volume of the bigger can
Multiply the old volume by 1 1/2
so
step 3
Find the height of the bigger can
we have
substitute in the formula
Answer:
20+4x=10+2x
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
We can use the slope formula to help complete this question
m = (y2-y1)/(x2-x1)
-1 = ( -6-0)/(x- -3)
-1 = -6/ (x+3)
Multiply each side by (x+3)
-x-3 = -6
Add 3 to each side
-x -3+3 = -6+3
-x =-3
Multiply each side by -1
x = 3
Find the polar coordinates in the usual way, then negate r and add 180° to θ.
You know that
... r = √(x² + y²)
... θ = arctan(y/x) . . . . . taking quadrant into account
The coordinates (r, θ) and (-r, θ+180°) specify the same point.
