Answer:
Step-by-step explanation:
The range of f(x) = cos(x) is [-1, 1].
That of f(x) = A cos(x) is [-A, A], and
That of f(x) = A cos(x) + 2 is [ b-A, b+A ].
The function g(x) = A sin(x)+b has the same range.
1.7 : 22.3
17 : 223 is the ratio. Times 10 throughout
The bigger number is 15 and the smaller number 7. 15 is 8 more than 7. The sum of 15 and 7 is 22.
