F(x) = x − 7 and g(x) = x2 . Find f(g(−1)).
1st let's find g(-1) → g(- 1) = (-1)² = 1
Now let's find f(1) →1 - 7 = -6
Yes, as there is only one variable, it makes the line straight
Answer:
C. w–2(n–1)
Step-by-step explanation:
One way to think of this is that the smallest is the n-th term of an arithmetic sequence with w as the first term and -2 as the common difference. The formula for the n-th term is ...
an = a1 + d(n -1)
Filling in the given values, we have ...
smallest number = w -2(n -1) . . . . . matches choice C
The ratio of students to adults in a community band = 47:53
47+53 = 100
ratio of students = 47
Hence, 47 % of the marching band is students.
