Answer:
x=2
Step-by-step explanation:
The axis of symmetry can be calculated using the following formula:

In order to use this formula, we need to have the function written in it's polynomial formula:

In order to do so, we have to isolate Y from the excercise's formula.

Then we resolve the square of the binomial knowing that (a+b)^2=a^2+2.a.b+b^2


Now we have that:



As we have now the polynomyal formula, we know that a=-2, b=8 and c=-13. We supplant on the formula and get:




Answer:
Step-by-step explanation:
The length of the polar coordinates ray is found using the Pythagorean Theorem: ray length = √( (-1)^2 + (-2)^2 ) = √( 1 + 4) = √5
Because both the x- and the y-coordinates here are negative, the ray is in Quadrant III. Measuring the angle counterclockwise from 0°, we get
Ф = 180° + arctan 2/1, or Ф = 180° + 63.43°, or 243.43°
The desired polar coordinates are (2√2, 243.43°)
Answer:
40.82
Step-by-step explanation:
C= 2x3.14x6.5 ( half the diameter is the radius)
formula for C= 2xπ(3.14)x radius( half the diameter)
Y = -7
x = -19
Steps:
Add the two equations together:
y - x + y + x = -14
2y = -14
y = -7
-7 + x = -26
x = -19
