Answer:
A=3(π/2)-1 au
Step-by-step explanation:
we have according to the graph that
f(x)=3
g(x)=cos(x)
Knowing A=∫|f(x)-g(x)|dx, then
; where a=0 and b=π/2

A=(3x-sin(x)) evaluated 0 ≤ x ≤ π/2
A=(3(π/2)-sin(π/2))-(3.0-sin(0))

Answer: 78
Step-by-step explanation:
6(4+9)
use foil to distribute the 6 to the 4 and 9
6×4 + 6×9

3- 0.5= 2.5 so
6- 3 1/2 is 2 1/2 or 2.5
