Answer:
x = -2
Step-by-step explanation:
f(x) = 2( x^2 +9x -5x - 45)
f(x) = 2(x^2 + 4x - 45)
f(x) = 2x^2 +8x -90
axis of symmetry formula: x = -b / 2a
x = -(8) / 2(2)
x = -8 / 4
x = -2
*you can also graph the equation on a graphing calculator and find the middle of the parabola
√102 = 10.09950494.....
So 10.09950494..... to the nearest tenth would be 10.10, because 9 comes AFTER 5 so we will go to the next number which would make the number 10.10.
SO, √102 ≈ 10.10.
Hope I helped ya!!!☺☺☺☺
Answer:
When we rotate a figure of 90 degrees counterclockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure. Example 1 : Let F (-4, -2), G (-2, -2) and H (-3, 1) be the three vertices of a triangle.
