the last step is wrong because we multiply the powers in this case we do not subtract them.
we use power subtract in division.
we use power multiplication when we raise to power and the root is power like square root of x
so
![\sqrt[3]{x} = {x}^{ \frac{1}{3} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bx%7D%20%20%3D%20%20%7Bx%7D%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20)
in our case
this step is wrong
![2x \times \sqrt[3]{ \frac{2}{y} \times \frac{y}{y} }](https://tex.z-dn.net/?f=2x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B2%7D%7By%7D%20%20%5Ctimes%20%20%5Cfrac%7By%7D%7By%7D%20%7D%20%20)
it should be
![2 x \times \sqrt[3]{ \frac{2}{y} \times \frac{ {y}^{2} }{ {y}^{2} } }](https://tex.z-dn.net/?f=2%20x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B2%7D%7By%7D%20%20%5Ctimes%20%20%5Cfrac%7B%20%7By%7D%5E%7B2%7D%20%7D%7B%20%7By%7D%5E%7B2%7D%20%7D%20%7D%20)
so we get
![2x \times \sqrt[3]{2 {y}^{2} \times \frac{1}{ {y}^{3} } }](https://tex.z-dn.net/?f=2x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B2%20%7By%7D%5E%7B2%7D%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B%20%7By%7D%5E%7B3%7D%20%7D%20%20%7D%20)
![= \frac{2x}{y} \times \sqrt[3]{2 {y}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B2x%7D%7By%7D%20%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B2%20%7By%7D%5E%7B2%7D%20%7D%20)
1)x+1) has positive slope, it is only A or B
2) For f(x)=4 we have x≥1, so this graph should begin with black dot.
3)So answer is B
Blue dot should be empty.
Orange dot should be black.
Answer:
????
Step-by-step explanation:
Answer:
D) y=-4x+2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-2-6)/(1-(-1))
m=-8/(1+1)
m=-8/2
m=-4
y-y1=m(x-x1)
y-6=-4(x-(-1))
y-6=-4(x+1)
y=-4x-4+6
y=-4x+2
You would have to divide by 3.14 to find the radius squared, and to find the diameter, just add the radius plus the radius.
