Which graph represents the function f(x) = (x – 3)2? On a coordinate plane, a parabola opens up. It goes through (negative 6, 8), has a vertex at (negative 3, 0), and goes through (negative 0, 8). On a coordinate plane, a parabola opens up. It goes through (negative 4, 7), has a vertex at (0, negative 9), and goes through (4, 7). On a coordinate plane, a parabola opens up. It goes through (1, 4), has a vertex at (3, 0), and goes through (5, 4). On a coordinate plane, a parabola opens up. It goes through (negative 2, 7), has a vertex at (0, 3), and goes through (2, 7).

Find the value of x for which line a is parallel to line b

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
