y=\dfrac{1}{3}x\\\\x=0\to\dfrac{1}{3}x=\dfrac{1}{3}(0)\to y=0\to(x,\ y)=(0,\ 0)\\\\x=1\to\dfrac{1}{3}x=\dfrac{1}{3}(1)\to y=\dfrac{1}{3}\to(x,\ y)=\left(1,\ \dfrac{1}{3}\right)\\\\x=2\to\dfrac{1}{3}x=\dfrac{1}{3}(2)\to y=\dfrac{2}{3}\to(x,\ y)=\left(2,\ \dfrac{2}{3}\right)

Solving Square Root Worksheet (x - k)^2 Part 3
erastova [34]

Answer:

7. x = -2 +/- 4i\sqrt{5}

8. x = 2 or x = 6

9. x = -2 +/- \frac{\sqrt{26} }{2} i

10. t = -3 +/- \sqrt{35}

Step-by-step explanation:

7. Subtract 320 from both sides: 4(x + 2)^2 = -320

Divide by 4: (x + 2)^2 = -80

Square root both sides: x + 2 = +/- \sqrt{-80}. We need to add the imaginary i to this: +/- \sqrt{-80} = +/- i\sqrt{80} = +/- 4i\sqrt{5}

Subtract 2 from both sides: x = -2 +/- 4i\sqrt{5}

8. Add 18 to both sides: 7(x - 4)^2 = 28

Divide by 7: (x - 4)^2 = 4

Square root both sides: x - 4 = +/- 2

Add 4 to both sides: x = 4 +/- 2  ⇒  x = 2 or x = 6

9. Add 5 to both sides: -2(x + 2)^2 = 13

Divide by -2: (x + 2)^2 = -13/2

Square root both sides: x + 2 = +/- \sqrt{-13/2}. We again need i: +/- \sqrt{-13/2} = +/- i\sqrt{13/2} = +/- \frac{\sqrt{26} }{2} i

Subtract 2 from both sides: x = -2 +/- \frac{\sqrt{26} }{2} i

10. Multiply by 5 on both sides: (t + 3)^2 = 35

Square root both sides: t + 3 = +/- \sqrt{35}

Subtract 3: t = -3 +/- \sqrt{35}

Hope this helps!

Find the area of a circle shaped swimming pool with a diameter of 22 meters. Use 3.14 the area of the circle is approximately ho
Kay [80]

Answer: 379.94

Step-by-step explanation: To find the area of a circle, you do radius squared times pi. To find the radius, divide the diameter in half. So 22 divided by 2 is 11. 11 squared is 121. Then multiply 121 by 3.14. That equals to 379.94

Charlie made the following table to record the height of each person in his family.
IRISSAK [1]

Answer:

4

Step-by-step explanation:

Since the question does not specify if you are rounding up or down, just round down to four from 4 1/6. 4 1/6 is closer to 4 than it is to 4 3/6 or 4 1/2.
