Answer:
-89
Step-by-step explanation:
The first term of the sequence is a1 = -12.
The common difference between terms is ...
d = -13 -(-12) = -1
The generic term is given by ...
an = a1 +d(n -1)
Then the 78th term is ...
a78 = -12 +(-1)(78 -1) = -12 -77
a78 = -89
Answer:
The volume is 105/512 cubic inches
Step-by-step explanation:
Given [Missing from the question]
-- Length
-- Width
-- Height
Required
Determine the volume.
The volume (V) is calculated as thus:
The standard formula of a point-slope equation is (y-y1) = m(x-x1). So, we would arrange the final equation in this way as much as possible. Let y be the total amount her receives and x be the number of miles. That would be
y = 200 + 20x
y = 20 (10 + x)
That would be the equation. If he finishes the walk,
y = 20 (10+5)
y = $300
he would receive a total of $300.

Answer: -(x+8)(x-8)
Step-by-step explanation:
-(x^2-64)
x^2-8^2x^2
x^2-8^2=(x+8)(x-8)
-(x+8)(x-8)
