Answer:
-3 < x ≤ 6
Step-by-step explanation:
Left side is exclusive, right side is inclusive, hence the < and ≤, respectively.
I'm pretty sure to solve this all you do is subtract 77.95 - 75.65, which would be 2.30. Hope that helps!
Answer:
A. -2sin(x)sin(0.4x)
Step-by-step explanation:
At x=0, the given expression evaluates to zero.
For x near zero, the given expression is slightly negative. You know this because cos(1.4x) decreases faster than cos(0.6x), so their difference will be negative.
Of the answer choices, you can eliminate C and D because they are not zero at x=0. You can eliminate choice B, because it is positive for values of x near zero. The only viable choice is A:
-2sin(x)sin(0.4x)
___
Of course, a graphing calculator can help you figure this out. See the attachment. The given expression is plotted using a solid red line; the answer choice A is plotted using blue dots.
Answer:
120 ft by 180 ft
Step-by-step explanation:
If every inch is 15 feet multiply 8 inches by 15 and then 12 by 15 to get your dimensions
15 * 8 = 120
15 * 12 = 180
120 x 180 feet
Convert to inches if needed.
1440 inches by 2160 inches
