A rectangle rotated about an axis creates a cylinder
Answer:
v=9 cm³
sa=30 cm²
Step-by-step explanation:
v=3*3*1=9cm³
sa=(2*3*3)+(4*3*1)=18+12=30 cm²
Answer:
Step-by-step explanation:
Is this graphing? If so, remember the formula: y=mx+b
If it's y=-1/3x+1, then 1 is your slope intercept
Place the dot on your graph where 1 is on your y-intercept.
Graphing -1/3x is just like rise over run, positives go up then right, (If 1/3 was graphed you would go 1 pixel up then 3 to the right.)
Since -1/3x is a negative, you're going down 1, left 3. It should give you a line that is coming from the top of the graphing box to the bottom.
If you want, create a table for x and y. If 0 was your x, then your y is 1, this is because theres a +1 in your equation.
If 3 was your x, then your y would be 0, because -1/3(3) + 1 is 0.
