Answer:
a line passing through (negative 4, 2), (0, 0) and (4, negative 2).
Step-by-step explanation:
A function exhibiting direct variation MUST pass through the origin, (0, 0), and the graph must be a straight line. The answer that satisfies these requirements is
a line passing through (negative 4, 2), (0, 0) and (4, negative 2).
Solving this problem actually requires us the use of the
distance formula of point to a line.
The formula is:
distance = | a x + b y + c | / sqrt (a^2 + b^2)
So we are given the equation:
y = 2 x + 4
rewriting:
<span>y – 2 x – 4 = 0 -->
a = -2, b = 1, c = -4</span>
We are also given the points:
(-4, 11) = (x, y)
Using the distance formula at points (x, y):
distance = | -2 * -4 + 1 * 11 + -4 | / sqrt [(- 2)^2 +
(1)^2]
distance = 15 / sqrt (5)
distance = 6.7
<span>So the tree is about 6.7 ft away from the zip line.</span>
-5 -(-1) = -5+1= -4
and
-9 -(-5) = -9+5 = -4
we observe that the number are in AP
of the AP -
ist term = -1
common difference = -4
19th term = -1 + (19-1)(-4)= -1 -72 = -73

the correct answer = B
This is substitution, it's very simple once you get the hang of it!
okay, what you want to do is plug in the numbers you already have, to get the number you don't have(r).
First, you plug in the numbers.
1. P= $2000
A=$2543
t= 4(years)
r=?
2543=2000^r(4)
Secondly, you want to solve the equation.
Answer:
1,249 cm or 12.49
Whichever one it asks for
Step-by-step explanation:
First, we need to convert all of the m to cm.
4.04 m = 404 cm
1.6 m = 160 cm
2.87 m = 287 cm
Next, add them all up.
325 + 404 + 73 + 160 + 287 =
1,249 cm
If it asks to convert to m again, then the answer would be 12.49 m
Hope this helps!!!
