Answer:
1. Neither (quadratic)
2. Exponential
Step-by-step explanation:
= y <- this is an example of an exponential equation.
y = 2x + 1 <- this is a linear equation
Answer:
49.5 units²
Step-by-step explanation:
The applicable formula is ...
Area = 1/2·ab·sin(C) = (1/2)·15·13·sin(30.5°) ≈ 49.48499
≈ 49.5 . . . square units
Sin T = 2/3 in QII means y = -√5 By Pythagoras
cos T = -√5 / 3
