{1,2,3,...,75,76,78} how many numbers in the set above have 2 as a factor but not have 10 as a factor
A) 32
B) 35
C)39
D)40

A) 32

Step-by-step explanation:

From 1 to 10 we have 4 numbers which are {2,4,6,8}

From 10 to 20 we have 4 numbers which are {12,14,16,18}

.

.

From 70 to 78 we have 4 numbers which are {72,747,6,78}

conclusion: we 4×8 number = 32

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
