Because for input=-2 there are more than one outputs. It means the this is not a function and it’s impossible to find a rule.
Answer:
the answers are B,D and E
Step-by-step explanation:
Answer:
C. 7.8
Step-by-step explanation:
This problem involves the use of a trigonometric ratio. This one specifically involves the use of cosine as it provides the leg adjacent to the angle and the hypotenuse.
cos(40) = 6/x
cos(40)*x=6/x*x
cos(40)*x=6
cos(40)/cos(40)*x=6/cos(40)
x=6/cos(40)
x=7.83
The value of x is C. 7.8
The value of N is 289.
Step-by-step explanation:
A sequence of number is given with a missing number "N".
To find N, find which pattern is followed in the sequence:
The sequence goes on reducing with small number than the previous one.
so, finding the difference= 400-361= 39
361-324= 37
It is found that 39-37= 2.
37-2= 35 and follows as 33 and 31.
So, the next number N can be find by 324-N= 35
324-35= N
N= 289
check whether the next number is followed correctly or not,
289-256 must give 33 and 256-225 gives 31. <u>So the N value is correct.</u>
