The answer is -64 or -2^6
Answer:
for question one - x = 12
Step-by-step explanation:
a triangle is always 180, in other words you will add all the corners equal to 180
ex (for first question) - 7x -2 + 4x + 5x - 10 = 180
you add like terms, the x with x and single numbers with numbers, which results in 16x - 12 = 180. then you do the original operation "what you do to one sign of the equal side you do to the other"
Cos(2x) = cos^2(x) - sin^2(x) - cos(x)
but sin^2(x) = 1 - cos^2(x)
cos(2x) - cos(x) = cos^2(x) - (1 - cos^2(x) ) - cos(x)
cos(2x) - cos(x) = cos^2(x) - 1 + cos^2(x) - cos(x)
cos(2x) - cos(x) = 2cos^2(x) - 1 - cos(x)
cos(2x) - cos(x) = (2cos(x) + 1)(cos(x) - 1)
I think this is what you have asked for.
Answer:
1.
Mathematical concept that expresses an amount in relation to the computer unit; results from counting the elements that make up a set.
"Cardinal number"
2.
A graphic sign or set of graphic signs that expresses or represents that amount.
Step-by-step explanation:
Answer:
Hey there!
The range is the possible y values, so the range of this graph would be all real numbers less than or equal to -6.
Let me know if this helps :)
