Answer:
2. 4th degree polynomial
Step-by-step explanation:
The degree is the highest exponent in the expression. Since the highest exponent is 4, this is a 4th degree polynomial.
The same value as cosα
cosα=sin(90-α) and vice versa
sinα=cos(90-α)
Answer:
x = 14
Step-by-step explanation.
First I would use sine to find x's value. So ----> sin(30) = 7/x ----> x sin(30) = 7 ----> x = 7/sin(30) = 14.
You Can also find that x is equal to 14 by applying the 30, 60, 90, triangle rule. Becuase '7' opposes the 30 degree angle it is 1/2 the hypotenuse, if thats the case just multiply the 7 by 2 and you have the hypotenuse length.
Answer: 24
explanation: mode is the value that repeats most often. so, in this case, 24 repeats the most often.
Answer:
x = ± 2i
Step-by-step explanation:
note that 
= i
x² = - 12 ( take square root of both sides )
x = ± 
= ± 
= ± 2i
