Below is the graph of a trigonometric function. It intersects its midline at (1.25, -2.75) and it has a minimum point at (4.75, -6.25).

Need ! discuss how to convert the standard form of the equation of a circle to the general form. 50 points

Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.1. (round your answers to four decimal places.) (a) if the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51?

Which graph corresponds to the function f(x) = x2 + 4x – 1?
