The slope of the line is ![m=-\frac{1}{2}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B1%7D%7B2%7D)
Explanation:
Given that a coordinate plane with a straight line passing through the points
,
and ![(4,-2)](https://tex.z-dn.net/?f=%284%2C-2%29)
We need to determine the slope of the line.
The slope of the line can be determined using the formula,
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Since, the points
,
and
lie on the straight line and the slope of all the points in a straight line have the same slope.
Hence, let us consider the points
and ![(0,0)](https://tex.z-dn.net/?f=%280%2C0%29)
Let us substitute these points in the slope formula, we have,
![m=\frac{0-2}{0+4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B0-2%7D%7B0%2B4%7D)
Simplifying, we get,
![m=\frac{-2}{4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-2%7D%7B4%7D)
Dividing, we get,
![m=-\frac{1}{2}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B1%7D%7B2%7D)
Hence, the slope of the line is ![m=-\frac{1}{2}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
a) (i) length = 2(pi)r = 2(3.14)(.5 m) = 3.14 m
(ii)3.14 m × ($4.70/m) = $14.76
b) A = (pi)r^2 = (3.14)(18 m)^2 = 1017.9 m^2
Answer:
multiply the ratio of quantities by 100%
Step-by-step explanation:
You usually explain a process by describing how it is done. The ratio of two quantities is expressed as a percentage by multiplying that ratio by 100%.
<u>Example</u>
A as a percentage of B is (A/B)×100%.
_____
You will often see a description of finding a percentage as involving multiplication by 100. What multiplication by 100 does is give you a quantity 100 times as large. Generally, that will not be the number you are looking for.
For example, <em>one out of four</em> as a percentage is not (1/4)·100 = 25. 25 is two tens plus 5, a number way larger than 1/4. Rather, it is (1/4)·100% = 25%.
"Percent" and "hundredths" are interchangeable. The percent symbol (%) is a shorthand way to write /100, which is what it means. Consider the above example:
25% = 25/100 = 1/4 . . . . these are all the same value, written differently
In decimal, ...
25% = 25/100 = 0.25 . . . . these are all the same value, written differently
