4.) Recursive formula => f(n + 1) = f(n) - 3
Explicit rule => f(n) = a + (n - 1)d = 35 + (n - 1)(-3) = 35 - 3n + 3 = 38 - 3n.
f(n) = 38 - 3n
5.) Recursive formula => f(n + 1) = f(n) + 7
Explicit rule => f(n) = 58 + (n - 1)7 = 58 + 7n - 7 = 51 + 7n
f(n) = 51 + 7n
Answer:
$9212
Step-by-step explanation:
15000-2250 = 12750 (1st year)
12750-1913 = 10838 (2nd year)
10838-1626 = 9212 ( 3rd year)
Answer:
Its 1
Step-by-step explanation:
Answer:
1: x = 29
2: Angle C is 93 degrees
Step-by-step explanation:
For 1 angle C has to equal 93 degrees since 52 + 35 = 87 and 180 - 87 = 93, and a triangles interior angles add up to 180 degrees.
From there create an equation: 3(x + 2) = 93 then solve
3x + 6 = 93
-6 from both sides
3x = 87
/3 from both sides
x = 29
For 2 just plug in x (29)
3(29 + 2)
87 + 6
93
