ten more than twice a number is 36. what is the number? write an algebraic expression then solve for the number

aniked [119]

10 more than (+) twice a number (2x) is (=) 36

10 + 2x = 36 Subtract 10 from both sides
2x = 26 Divide both sides by 2
x = 13

Which expression is equivalent to cos(1.4x) − cos(0.6x)?

givi [52]

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.
