Answer:
$158.8
Step-by-step explanation:
There are 12 months in 1 year.
If in 1 year, it looses value of 10.3%, so in a month it will loose value of:
10.3%/12 = 0.8583% per month
So, to find the decreased value (in dollars) per month, we got to find 0.8583% of 18,500 dollars.
First, we need to convert percentage to decimal by dividing by 100. Then we multiply that to 18,500 to get our answer. So:
0.8583% = 0.8583/100 = 0.008583
Now,
0.008583 * $18,500 = $158.7855
Rounded to nearest tenth (1 decimal pae) = $158.8
Answer:
The equation that represents the new path is y=(1/3)x+4
Step-by-step explanation:
step 1
Find the slope of the give line
we have
y=-3x-6
so
the slope m is equal to
m=-3
step 2
Find the slope of the perpendicular line to the given line
Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal of each other
so
we have
m=-3 -----> slope of the given line
therefore
The slope of the perpendicular line is equal to
m=1/3
step 3
With m=1/3 and the point (-3,3) find the equation of the line
y-y1=m(x-x1)
substitute
y-3=(1/3)(x+3)
y=(1/3)x+1+3
y=(1/3)x+4 -----> equation that represent the new path

y = 2x + 3
the equation of a line in slope-intercept form is
y = mx + b ( m is the slope and b the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁) = (- 2, - 1) and (x₂, y₂) = (2, 7)
m = 
= 
= 2
y = 2x + b ← is the partial equation
to find b substitute either of the 2 points into the partial equation
using (2, 7 ), then
7 = 4 + b ⇒ b = 7 - 4 = 3
y = 2x + 3 ← in slope-intercept form
