Answer:
a = -4, b = -3
Step-by-step explanation:
P(2) = 0
= 4a +2b = -10
P(4) = 6
= 16a + 4b = -52
16a + 4b = -52 - 8a + 4b = -20
= 8a = -32
a = -4
b = -3
Answer:
A
Step-by-step explanation:
Each domain value (x-value) of a function has exactly one range value (y-value).
A function can have two or more domain (x-value) having the same range (y-value)
Graph A shows the different domain value (x-values) having exactly one range value (y-value). No x-value has two different y-values.
Therefore, graph A is a function.
Answer:
525
Step-by-step explanation:
Congruent angles of what... be more specific please..
First, we need to solve for the common ratio from the data given by using the equation.
a(n) = a(1) r^(n-1)
15 = -3 r^(2-1)
-5 = r
r = -5
Then, we can find the sum by the expression:
S(n) = a(1) ( 1 - r^n) / 1-r
S(8) = -3 (1 + 5^8) / 1+5
S(8) = -195313
