42x + 28y......the GCF is 14...so factor out 14
14(3x + 2y) <==
Answer:
sin = √2/2, cos = -√2/2, tan = cot = -1
csc = √2, sec = -√2
Step-by-step explanation:
Angle runs around unit circle (where x^2+y^2=1)
from (1,0) to (-√2/2,√2/2)
Answer:
1k or k
Step-by-step explanation:
Lets solve the problem without k. The problem would be -6+7. The answer is 1. Then we add the k at the end.
We get 1k, which can be written as just k.
Answer = B
Explanation :
The expression (the answer) is equal to 4^5 times 4^-7 divided by 4^-2
Expression = 4^5 x 4^-7 divided by 4^-2
Since the base for all terms are the same(all bases are 4)
All we have to do is add and subtract the exponents accordingly
4^5 x 4^-7 = 4^-2
Now what’s left of the equation is 4^-2 divided by 4^-2
When you divide any number by itself (except 0) you always get 1 as the asnwer
4^-2 divided by 4^-2 = 1
Answer choice B = 4^0 (4^0 equal 1, when a number has an exponent of 0 the answer will be 1)
Answer = B
