Answer:
10n+(10 x 15)
or
(10 x n)+150
either way it would be 270
X= 7 don’t know why i have to keep typing for it to post
Which situation could best be represented by the integer 120?
1. could be negative but the likely of losing 120 pounds is very low
2. this number would be positive
3. could be between -1 to - infinity
answer: 3. the number of feet below a surface
Answer:
sin 5x cos x - cos 5x sin x = sin(4x)
Step-by-step explanation:
Given that the trigonometric expression,
sin 5x cos x - cos 5x sin x
Here we use the "sum and difference formulas"
Sum and Difference Formulas
sin(A+B)=sin A cos B + cos A sin B
sin(A-B)=sin A cos B - cos A sin B
cos(A+B)=cos A cos B - sin A sin B
cos(A-B)=cos A cos B + sin A sin B
So,
sin 5x cos x - cos 5x sin x = sin (5x - x)
sin 5x cos x - cos 5x sin x = sin(4x)
That's the final answer.
