Answer:

answer is no, not a right triangle

Step-by-step explanation:

if it is a right triangle then the sum of the square of the two smaller legs will equal the square of the longest leg

does 8² + 12² equal 15²?

64 + 144 = 225

208 ≠ 225

answer is no, not a right triangle

A washer and a dryer cost $744 combined, the washer costs $94 more than the dryer, what is the cost of the dryer?

sp2606 [1]

Answer: 325$

Explanation:
Assume: A is the cost of washer
And B is the cost of dryer

A+B = 744
And: A = B + 94$
We get:

B + 94$ + B = 744
2B + 94 = 744
2B = 650
B = 325

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.
