Triangle A B C is shown. Angle A C B is a right angle. The length of hypotenuse A B is 10.3 centimeters, the length of C B is 10 centimeters, and the length of A C is 2.4 centimeters. Angle A B C is x.
Which equation can be used to solve for the measure of angle ABC?

tan(x) = StartFraction 2.4 Over 10 EndFraction
tan(x) = StartFraction 10 Over 2.4 EndFraction
sin(x) = StartFraction 10 Over 10.3 EndFraction
sin(x) = StartFraction 10.3 Over 10 EndFraction

Which of the following is true for the relation f(x)=2x^2+1

State if the two triangles are congruent. if they are, state how you know?

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.
