7.0, 7.2, 7.4, 7.6, 7.8, 8.0, 8.2, 8.4
All are easy. There is no way to say thatnone way is easier than the other. Well the answer lies in every individual, it depends on which method they are comfortable with. Anyway there are more method to solve quadratic than the listed ones.
-(x+2)^2(x-4)^2
Not that if x= -2 and x=4 they will look like this in an equation: (x+2) and (x-4)
When (x+2) and (x-4) are set equal to zero and you solve for x, x will equal x= -2 and x=4
If they have double roots, they have a multiplicity of 2 (per root) meaning they will bounce off of the x-axis. Multiplicity can be found by using exponents.
The negative in front flips the function over the x-axis and holds true to the given limit.
I attached a picture of how I worked out the answer
Answer:
The distance from the feet to the wall is 9 ft
Step-by-step explanation:
Using trig,
We must use cosine to find the missing side.
The equation is cos 60 = 
The cosine of 60 is 1/2
So, we multiply 1/2 by 18
to get 9
Hope this helps!
Branliest would really be nice!
