The problem is an arithmetic sequence with:
a₁ = 206,300
an = 208,400
n = 2013 - 2000
n = 13
To find the annual increase, use this following formula
an = a₁ + d(n - 1)
d represents the annual increase
Input the numbers
an = a₁ + d(n - 1)
289,400 = 206,300 + d(13 - 1)
289,400 = 206,300 + 12d
289,400 - 206,300 = 13d
83,100 = 12d
12d = 83,100
d = 83,100/12
d = 6,925
The annual increase is $6925
Answer:
x=45
Step-by-step explanation:
An entire triangle is 180 degrees and you already know that one angle is 90 degrees. 180 - 90 is 90. Now you have the equation 2x=90.
You then divide each side by 2 to get the x by itself which leaves you with x=45.
Answer:
784
Step-by-step explanation:
The required x and y-intercept of the given line is -3 and -6/5 respectively.
<h3>What is the slope of the line?</h3>
The slope of the line is the tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The given equation of the line is 2x+5y=-6.
Transform into standard form of line .i.e is y = mx + c
5y = -2x - 6
y = -2x/5 - 6/5
here , m = -2/5 and c = -6/5
Since c = y-intercept of the line = -6/5
Now, put y = 0 in the equation of the line.
2x = -6
x = -3
Thus, the required x and y-intercept of the given line is -3 and -6/5 respectively.
