Answer:
y=27.8
Step-by-step explanation:
- 8^2=17^2+16^2-2(16)(17)cosY
- 8^2-17^2-16^2/-2(17)(16)=cosY
- -481/-544=cosY
- 0.8842=cosY
- Y is about 27.8
Answer:
g(x) = 3.5^x-2
Step-by-step explanation:
because g(0) = 3.5^0-2 = -1 and g(1) = 3.5^1-2 = 1.5
you know that g(x) = y and when x=0 y=-1 on the graph
and when x=1 y=1.5
