Answer:
4,370
Step-by-step explanation:
add 10,500, 1,300, and 2,170
then add 3,100 and 6,500
subtract both sums
got it
1.5 is lesser than 0.5. Oh, wait nevermind I meant to say -1.5 is lesser than 0.5
Answer:
6.47 x 10^-2
Step-by-step explanation:
Answer:
1.34 (3 sf)
Step-by-step explanation:
To find the area between 2 curves:

As these 2 curves intersect, we have to first calculate where they intersect, then work out the area between the curves BEFORE and AFTER the point of intersection, as the "top" and "bottom" curves change after the point of intersection (see attached graph).
sin(x) = cos(x)
⇒ tan(x) = 1
⇒ x = 
So the curves intersect at
(between x = 0 and x = 2)
To calculate the area between the 2 curves,
and
:

Then to calculate the area between the 2 curves,
and
:

Therefore, the total area =
