Common difference = 6 - 2.5 = 3.5
(B) recursive formula can be written as
U(n+1) = U(n) + 3.5n
where value of n is 0 to infinity
Answer:
-10x+2+x=-4x+12
-9x+2=-4x+12
-9x+4x+2=12
-9x+4x=12-2
-5x=10
x=-2
Step-by-step explanation:
Answer:
y = -1/2x + 2
Step-by-step explanation:
Given the following points on the line:
(0, 2) and (6, -1)
We need to find the slope of the line using the following formula:
m = (y2 - y1)/(x2 - x1)
Let (x1, y1) = (0, 2)
(x2, y2) = (6, -1)
Plug these values into the slope-formula:
m = (y2 - y1)/(x2 - x1)
m = (-1 - 2) / (6 - 0)
m = -3 / 6
m = -1/2
Therefore, the slope of the line is -1/2.
Next, we need to find the <em>y-intercept</em> of the line. The y-intercept is the point on the graph where it crosses the y-axis. It is also the value of y when x = 0. If you look at the graph, you'll see that the line crosses the y-axis at point (0, 2), which happens to be one of the points we used earlier. The y-coordinate of (0, 2) is the y-intercept.
Therefore, the y-intercept (b) = 2.
We can write the linear equation as follows:
y = -1/2x + 2
To answer this question, you need to understand how to convert a unit. In this case, the conversion would be milli meter to feet. Since it area(the unit is ^2), the conversion needs to be done twice.
The calculation would be:
(6.490^10^3 mm2) / (304.8mm/ft) / (304.8mm/ft) = 0.06985= 6.985* 10^-2 ft2
The sequence 20 , 11 , 2 , -7 is an arithmetic sequence.
The common difference is (20 - 11) = (11 - 2) = (2 - -7) = 9
The common difference is 9.
