2. Which of the following is NOT the key features of quadratic graph?
A. The graph of a quadratic function is a parabola,
B. The graphs of quadratic functions have a constant rate of change,
C. The graph can be both concave up and down,
D. The graphs of quadratics are symmetrical about the axis of symmetry,

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 23 = 10x a. -1.93, 11.93 b. 1.93, -11.93 c. 1.93, 11.93 d. -1.93, -11.93

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.

Extremely mega ultra important question! plss answer as fast as you can you will get 84 points! the area of this right triangle is half the area of which of these rectangles?
