C.
By plugging in the numbers into the equation, 8 = 250(k), we can determine that 8 ÷ 250 = 0.032.
Answer:
The 'n = 1' below sigma represents the <em>lower </em><em>bound</em><em>.</em> meaning the number from which you start adding.
'25' above sigma is the <em>upper </em><em>bound</em><em>.</em>
In general it means adding 42 from 1 to 25 times.
so 42(25).
Answer:
m=1/2
Step-by-step explanation:
This equation is in slope intercept form. The slope-intercept form of a linear equation is:
y
=
m
x
+
b
Where
m
is the slope and
b
is the y-intercept value.
y
=
1
2
x
+
2.3
Therefore, the slope of the line in the problem is:
m
=
1
2
Two parallel line, by definition, will have the same slope
Therefore, the slope of any line parallel to the line in the problem is also:
m
=
1
2

Answer:
- f(0) ≈ 22
- f(1) = 10
- f(b) ≈ -8
- f(c) = 0
- f(d) 24
Step-by-step explanation:
This takes graph-reading one step further. You get to estimate the y-value without benefit of minor grid lines. You must mentally divide the 10-unit distance between grid lines into equal spaces. Then estimate how many of those spaces lie between the point and the nearest grid line.
You can do this more precisely by drawing a diagonal line across the grid from one major grid intersection to one that is (5, 1) or (5, -1) major grid points away. Where that line crosses the intermediate grid lines, the vertical measure will be some multiple of 1/5 of the vertical difference between grid points. For example, a line from (0,20) to (5,30) will cross at (1,22), (2,24), (3,26), and (4,28). You can use these reference points to identify the y-values at f(0) and f(d).
Here's our eyeball estimate:
- f(0) ≈ 22
- f(1) = 10
- f(b) ≈ -8
- f(c) = 0
- f(d) 24
