If you graphed x squared plus y squared equals 1 what exact points would 30 45 60 75 and 90 degrees intersect?
The equation x2 + y2 = 1 is the equation for the unit circle, with center at (0,0). The intersections between that circle and the lines emmanating from (0,0) having angles of 30, 45, 60, 75, and 90 degrees relative to the positive x-axis would be 30 = (0.866, 0.5), 45 = (0.707, 0.707), 60 = (0.5, 0.866), 75 = (0.259, 0.966), and 90 = (1, 0).
In each case, the x coordinate is the cosine of the angle and the y coordinate is the sine of the angle. All answers have been rounded to three significant places.
What else can I help you with?
Is x plus y2 equals 25 a linear equation?
No, not if the y is squared. When graphed the equation will not form a straight line.
What is the point of intersection of the parabolas of y equals 3x squared plus 10x plus 11 and y equals 2 -2x -x squared?
They intersect at the point of: (-3/2, 11/4)
When 2 straight lines intersect the sum of the adjacent angles equals?
180 degrees
What is the formula in triangle?
Angle A + Angle B + Angle C = 180 degrees. If one angle equals 90 degrees then it is a right triangle and the lengths of the sides are in a ratio such that A squared plus B squared equals C squared (Pythagorean Theorem)
How many solutions does 2x plus y equals 5 and 2x plus y equals 4 have?
None. When these two equations are graphed, the two lines are parallel. Since they never intersect, there is no point that satisfies both equations.
What type of lines are y equals 2x and y equals 4x plus 2?
Those two statements are linear equations, not lines. If the equations are graphed, each one produces a straight line. The lines intersect at the point (-1, -2).
Where do the curves of y equals 4x squared -2x -1 and y equals -2x squared plus 3x plus 5 intersect?
They intersect at points (-2/3, 19/9) and (3/2, 5) Solved by combining the two equations together to equal nought and then using the quadratic equation formula to find the values of x and substituting these values into the equations to find the values of y.
What is -40 degrees celsius in Fahrenheit degrees?
-40 degrees Celsius is equal to -40 degrees Fahrenheit. The Celsius and Fahrenheit scales intersect at this temperature.
How do you find degrees of freedom for a chi-squared test?
The degrees of freedom for a chi-squarded test is k-1, where k equals the number of categories for the test.
What number squared equals 30?
5.477225575 squared equals 30.
What equals 121 when its squared?
The number that equals 121 when squared is 11.
