The x-value corresponds to a y-value of 1 is π
Step-by-step explanation:
The given is:
- y = - cos x
- y = 1
- 0 < x < 2π
We need to find x when y is 1
∵ y = - cos x
∵ y = 1
∴ 1 = - cos x
- Multiply both sides by -1
∴ -1 = cos x
- Switch the two sides
∴ cos x = -1
- Use the inverse of cos to find x
∴ x = 
∵ cos(π) = -1
∴ x = π
The x-value corresponds to a y-value of 1 is π

Answer:
4 cups of mayonnaise.
Step-by-step explanation:
The ratio of the amount of pecans comparing reality and the recipe is:
1 : 3/8
= 1/(3/8)
= 8/3
Hence, to find the amount of mayonnaise that should be added:
8/3 * 3/2
= 8/2
= 4 cups

Answer:
c) 0.0156
Step-by-step explanation:
The general term a[n] of a geometric sequence is given in terms of the first term a[1] and common ratio r as ...
a[n] = a[1]r^(n-1)
The given sequence has an initial term of a[1]=8 and a common ratio of 4/8=1/2. Then the general term is ...
a[n] = 8(1/2)^(n-1)
The 10th term is then ...
a[10] = 8(1/2)^(10-1) = 8(1/2)^9 = 8/512
a[10] = 0.015625 ≈ 0.0156
