For this case the first thing we must observe is that the mass increases 0.4 grams when the diameter increases 1 millimeter.
Therefore, the slope of the line is given by:
m = 0.4
Thus, the function that best suits the table is given by:
f (x) = -4 + 0.4x
For example, for x = 20 we have:
f (20) = -4 + 0.4 (20)
f (20) = -4 + 8
f (20) = 4
The result, matches the table.
Answer:
The function that is best represented by the scatter plot is:
f (x) = -4 + 0.4x
So he worked 30.5 hours, he just didn't write some of the hours down. To find the hours he didn't write down, you subtract 8+
+
from 30.5, which equals
Answer:
x=1,13
Step-by-step explanation:
(x – 7)^2 = 36
Take the square root of each side
sqrt((x – 7)^2) = sqrt(36)
x-7 = ±6
x-7 = 6 x-7 =-6
Add 7 to all sides
x-7+7 = 6+7 x-7+7 = -6+7
x = 13 x=1
