Answer:
cos(x)+1 or cos x + 1
Step-by-step explanation:
The wave starts at y=2 this means it is a cosine function, then the first positive x-intercept is at about (pi, 0) which is about 3, this leads to cos x + 1 as the answer.
Answer:
9n - 8
Step-by-step explanation:
The sequence is arithmetic since the difference between consecutive terms is common
d = 10 - 1 = 19 - 10 = 28 - 19 = 9
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 1 and d = 9, thus
= 1 + 9(n - 1) = 1 + 9n - 9 = 9n - 8, hence
= 9n - 8
Answer: y = 10x + 160
Step-by-step explanation:
The cost follows the linear equation format of:
y = mx + c
Where:
y = dependent variable or the total cost
m is the cost per each additional unit of x
x is the number of video games
c is the constant cost or rather the fee per bulk purchase
Formula is therefore:
y = 10x + 160
Using the formula. Assuming Kara buys 100 video games, the cost would be:
y = 10 * 100 + 160
y = $1,160
- Both n and k are positive i.e n,k>0
So the domain of n is
Now
- N has total 100+1=101 integer values
- K will also have 100+1=101values .
So total solution sets are 101 .
