Rewrite y=0.9^(t + 2) in the form y=a(1+r)^t or y=a(1−r)^t. Then tell whether the model represents exponential growth or exponential decay.

The line containing the midpoints of the legs of right triangle abc where a(-5,5), b(1, 1), and c(3, 4) are the vertices.

1) in triangle the, what is the measure of angle t (in degrees)? 2) in triangle bat, the measure of angle b is 66∘, and the measure of angle t is 77∘.what is the measure of the exterior angle at a (in degrees)?

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
