Answer:
-2x+3
Step-by-step explanation:
Using y=mx+b
To make the line perpendicular, you just need to make the slope (m=2) negative. To make it go through (-1, 5), you just need to adjust the b value to raise the graph to a point where it will pass through the point.
Answer:
The sprinkler can spread water 18 feet away.
Step-by-step explanation:
We are given the following in the question:
Area formed by watering pattern = 1,017.36 square feet
We have to find the how far the sprinkler spread the water.
The sprinkler covers a circular area. We need to find the radius of this circular area to find the how far the sprinkler spread the water.
Area of circle =![A = \pi r^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%5E2)
Putting values, we get:
![1017.36 = 3.14 r^2\\\\r^2 = \dfrac{1017.36}{3.14}\\\\r^2 = 324\\r = \sqrt{324} = 18\text{ feet}](https://tex.z-dn.net/?f=1017.36%20%3D%203.14%20r%5E2%5C%5C%5C%5Cr%5E2%20%3D%20%5Cdfrac%7B1017.36%7D%7B3.14%7D%5C%5C%5C%5Cr%5E2%20%3D%20324%5C%5Cr%20%3D%20%5Csqrt%7B324%7D%20%3D%2018%5Ctext%7B%20feet%7D)
Therefore, the sprinkler can spread water 18 feet away.
1. The word is inverse not inverese.
2. Where is the question?
Answer:
6
Step-by-step explanation:
DB/AD = AD/DC
so
AD² = DB x DC
AD² = 9 x 4
AD² = 36
AD = 6

note, it can be doing if PART A you answer the pair is ∆ABD with right angle in A and ∆ADC with right angle on D
