Answer:
a19 = -71.74
Step-by-step explanation:
The general term of an arithmetic sequence with first term a1 and common difference d is ...
an = a1 +d(n -1)
The given 5th and 15th terms tell us ...
-3.7 = a1 +d(5 -1)
-52.3 = a1 +d(15 -1)
Subtracting the first of these equations from the second, we find ...
10d = -48.6
d = -4.86 . . . . . . divide by 10
The 19th term will be ...
a19 = a1 +d(19 -1)
Subtracting the 15th term from this, we find ...
a19 -a15 = 4d
a19 = 4d +a15 = 4(-4.86) +(-52.3)
a19 = -71.74
Answer:
D
Step-by-step explanation:
To inverse a function, switch the y for x and x for y and solve for y
f(x) = 2/(x-3)
y = 2/(x-3)
x = 2/(y-3)
x*(y-3) = 2
y-3 = 2/x
y = 2/x-3
y = 2/x - 3x/x
y = 2+3x/x

Answer:
0.075 is less
Step-by-step explanation:
It is 0.075 because 0.96 is closer to 1 and so is greater
