The distance between two points (2,-2) and (0,-9) is 7.3 units, which is obtained by graphical method and formula method.
Step-by-step explanation:
The given is,
Two points are (2,-2) and (0,-9)
Step:1
By graphical method,
For two points (2,-2) and (0,-9)
First point (2,-2)
The values of x=2 and y=-9 noted in the graph
Second point (0,-9)
The values of x=0 and y=-9 noted in the graph
Now join the two points, measure the distance between the two points,
Distance between points are 7.3 units.
( OR )
Step:1
By formula method,
Distance = ![\sqrt{(x_{2}- x_{2}) ^{2}+ (y_{2}-y_{1}) ^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-%20x_%7B2%7D%29%20%20%5E%7B2%7D%2B%20%28y_%7B2%7D-y_%7B1%7D%29%20%20%5E%7B2%7D%20%20%7D)
Where,
( 2,-2) are (
)
(0,-9) are (
)
From the values,
= ![\sqrt{(0- 2) ^{2}+ (-9+2) ^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%280-%202%29%20%20%5E%7B2%7D%2B%20%28-9%2B2%29%20%20%5E%7B2%7D%20%20%7D)
= ![\sqrt{(- 2) ^{2}+ (-7) ^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B%28-%202%29%20%20%5E%7B2%7D%2B%20%28-7%29%20%20%5E%7B2%7D%20%20%7D)
= ![\sqrt{4+49 }](https://tex.z-dn.net/?f=%5Csqrt%7B4%2B49%20%20%7D)
= ![\sqrt{53}](https://tex.z-dn.net/?f=%5Csqrt%7B53%7D)
= 7.280
≅ 7.3
Distance = 7.3
Result:
The distance between two points (2,-2) and (0,-9) is 7.3 units, which is obtained by graphical method and formula method.
Answer choice B is the correct answer the rest don't make sense.
Answer:
y = 6x
Explanation:
This question is asking you to write a linear equation in slope-intercept form, <u>y = mx + b,</u> where m is the slope and b is the y-intercept.
The y-intercept (where the line crosses the y-axis) is visibly 0. As for the slope, you can take two points, I'll use (0,0) and (0.1,0.6) to calculate it.
Slope = y - y/x- x
Slope = (0.6 - 0)/(0.1 - 0) = 0.6/0.1 = 6
Plug in 0 for b and 6 for m and you have an equation.
y = 6x + 0
y = 6x
Answer:
see explanation
Step-by-step explanation:
Given
V = πr²h ( isolate r² by dividing both sides by πh )
= r² ( take the square root of both sides )
= r
