Answer:
It's a parabola
Step-by-step explanation:
If you write the equation as
x =3y2
, you can see that you are in the form
f
(y)=3y2
. This is a quadratic polynomial in
y
, which means that it represents a parabola with axis parallel to the
x axis.
An equivalent measurement to 2 meters is 200 cm. Since 1 meter is equivalent to 100 cm, multiply both of them by two. So, your answer is - 2 meters is equivalent to 200 cm.
Hope it helps :)
Answer: D
Step-by-step explanation:
If segment D moves downward it means its function has a negative slope so the line will be decreasing.
If they do not have a line of best fit this may be because there is no correlation
. Correct option C)5.38
<u>Step-by-step explanation:</u>
Here we have , Find the value of x. O is the center of the circle. Round your answer to the nearest hundredth. picture is attached . Let's find out:
In the given figure , Let's draw a line from center to the point where cord of length 8 unit is touching the circle or intersecting or , where this chord finishes . This line is radius of circle and is denoted by x , So now we have a right angle triangle with dimensions as :
![Perpendicular =3.6\\Base=\frac{8}{2}=4\\Hypotenuse=x](https://tex.z-dn.net/?f=Perpendicular%20%3D3.6%5C%5CBase%3D%5Cfrac%7B8%7D%7B2%7D%3D4%5C%5CHypotenuse%3Dx)
By Pythagoras Theorem ,
![Hypotenuse^2=Perpendicular^2+base^2](https://tex.z-dn.net/?f=Hypotenuse%5E2%3DPerpendicular%5E2%2Bbase%5E2)
⇒ ![x^2=(3.6)^2+(4)^2](https://tex.z-dn.net/?f=x%5E2%3D%283.6%29%5E2%2B%284%29%5E2)
⇒ ![x=\sqrt{(3.6)^2+(4)^2}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B%283.6%29%5E2%2B%284%29%5E2%7D)
⇒ ![x=\sqrt{12.96+16}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B12.96%2B16%7D)
⇒ ![x=\sqrt{28.96}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B28.96%7D)
⇒ ![x=5.38](https://tex.z-dn.net/?f=x%3D5.38)
Therefore ,
. Correct option C)5.38
