Answer:
5a^3-35a^2+30a
Step-by-step explanation:
solve 5a(a^2-7a+6)
step 1 (5a) (a^2+-7a+6)
step 2 (5a) (a^2)+(5a)(-7a)+(5a)(6)
Answer:
Base radius:
Step-by-step explanation:
Considering the cone is Right Circular Cone:
Volume of the cone =
Given :
Putting in the formula:
Multiply by '3' both sides:
Divide by '25.12' both sides:
So, the cone has base radius:
Answer:
2xsquared-2x
Step-by-step explanation:
You need to sub your X and Y values in. Take (-1,-3) for example: if you sub in these values, your equation y=-2x -1 will become (-3)=-2(-1) - 1. However, if you simplify it out, you'll realise that it doesn't make sense as you'll get -3=-1 which is clearly untrue, thus (-1,-3) is the only pair that doesn't satisfy your function.
Answer:
C
Step-by-step explanation:
You take the points and input them into the equation. If they all equal the set then it is the equation. So for example a point on the graph is (2,30) so in this case x is 2 so you would do y= 15(2) which is 30. So that equation and point checks out. Repeat with the others
