Answer:
amount in 30 years is $1787.0977
interest is $1387.0977
Step-by-step explanation:
Given data
principal amount = $400
rate = 5 % = 0.05
time period = 30 years
to find out
amount in 30 years and total interest
Solution
we know its interest compounded monthly so n = 12
and interest compounded monthly formula is
amount = principal ............1
put the value principal , n , rate and time in equation 1
we get amount
amount = 400
amount = 1787.0977
amount in 30 years is $1787.0977
and interest = amount - principal ............2
put the value amount and principal in equation 2
we get interest = $1787.0977 - $400
interest =$1387.0977
Given:
Points on the line are (5, 7) and (5, -5).
To find:
Equation of a line parallel to line l.
Solution:
Let us first find the slope of line l.
Slope of the line formula:
m = undefined
The line intersects at x-axis, so the y-intercept is 0.
Equation of line l is x = 5.
<em>If two lines are parallel, then their slopes are equal.</em>
In the option, find the line which also have slope undefined.
Option A: x = 5y
Divide by 5 on both sides, we get
Here slope is . So it is not parallel to line l.
Option B: x = -2
Here, the slope is undefined. It also passes through the x-axis.
Therefore, it is parallel to line l.
Option C: y = 5
Here, the line passes through y-axis.
So, it is not parallel to line l.
Option D: y = -5x.
Here, the slope is -5.
So, it is not parallel to line l.
Hence x = -2 is and equation for a line that is parallel to line l in the graph.
