The circle is open on 2. shade right on the nimber line
Answer:
14.4 inches
Step-by-step explanation:
Use the Pythagorean theorem:
So, this will be:
By simplifying we get:
c =
The missing side is: 14.4 (rounded to the tenth)
Break down the words into an equation:
(x+7)/(x+3) + (x-4)/3
Sequence: -4, 8, -16
rate of increase: -16/8 = -2
If you make A1 the first term in the sequence you must use (n-1) in the explicit formula. If you go backwards in the sequence to find A0 = 2 then you would use n.
The don't have A0 = 2 listed as an option so we use A1 = -4 and (n-1) terms.
An = -4(-2)^(n-1)
Solving for the 5th term A5, use n = 5
A5 = -4(-2)^(5-1)
A5 = -4(16)
A5 = -64
So the answer is B.
