Answer:
33 units²
Step-by-step explanation:
A (graphing) calculator shows you that f(4) ≈ 8, and f(8) ≈ 8.5. The curve is almost a straight line between, so the area is approximately ...
A = (1/2)(8 + 8.5)(4) = 33

If you do the integration, it gets a bit messy.
The appropriate answer choice is 33 square units.
300 dimensions of the room
Answer x=30
Step-by-step explanation:
Answer:
The correct choice is <u><em>option A. 2 < x < 10/3</em></u>
Step-by-step explanation:
|3x - 8| < 2
= -2 < |3x - 8| < 2
3x - 8 > -2 and 3x - 8 < 2
+8 +8 +8 +8
----------------- ------------------
3x > 6 3x < 10
/3 /3 /3 /3
----------------- -------------------
x > 2 x < 10/3
= 2 < x < 10/3
You would find 7*40 7*4=28
So 7*40=280 (just add a zero)
7*2=14
The answer would be 280+14=294
