This is an equation of degrees 6 so it will have a total of 6 roots.If you draw the
graph on calculator it touches the x axis at x = -2 and x = 2
If we plug in x =2 and x = -2 they fit the equation .
Also as the graph just touches the x axis this shows that x = 2 and x = -2 are duplicated
That gives us the 4 roots and also the +/- 2i giving a total of 6 roots.
The second option is correct
Answer: Yes, they are proportional
Step-by-step explanation:
Each side was multiplied by 2
Answer:
18*2/3+12
Step-by-step explanation:
So, out of 18, she only uses 2/3, so it will be 18*2/3, plus the additional 12 she downloaded.
Answer:
a
Step-by-step explanation:
Answer:
It would be 9,738.54
Step-by-step explanation: For starters, V= r^2(3.14)h
Make things easier by changing 20 1/2 to 20.5)) and 1 1/2 to 1.2))
Now multiply them to get your diameter. 20.5 * 1.20= 24.6.
You now have a diameter of 24.6. Now, divide 24.6 by 2 to get your radius. So, now you have a radius of 12.3. All you have to do now is plug in your numbers.
V= r^2(3.14)h V= (12.3)^2 (3.14) 20.5
you should get 9738.5373, but rounding by the hundredths place gets you 9738.54
Do well on your tests guys!
