Use the distance formula:
x2 is 1 and x1 is -2
y2 is root7 and y1 is 0
Point (X1,Y1) is basically the coordinate of the centre point of the circle
Point (X2,Y2) is the point that on the circle
So if the point(1,root7) is on the circle, the final distance you get should be the radius of the circle, which is 4 units
Calculate it and you can get the answer that is 4
Therefore the point (1,root7) is on the circle
Answer:
Step-by-step explanation:
Joint variations occurs when one variable depends on the value of two or more variables. The variable varies directly or indirectly with the other variables combined together. The other variables are held constant. From the given examples, the equation(s) that represent joint variations are
1) z = 3x/y
z varies directly with x and inversely with y.
2) w = abc/4
w varies inversely with a,b and c. 4 is the value of the constant of variation.
<u>Answer:</u>
The expression that represents "the sum of x and 8" is x + 8
<u>Solution:</u>
Given, a sentence “the sum of x and 8”
Now, we have to write an expression that represents the above given line and check the correct option.
So, now, let us take the given expression and convert it into the polynomial form.
Take, “the sum of x and 8" → sum of x and 8 → x + 8.
Here "+" denotes sum or addition.
Hence, expression for “the sum of x and 8” is x + 8 and option c is correct.

Hope it will help you :)
Step-by-step explanation:
Id say 0.187 because 0.033 times 17. then that number divided by 3
