Answer:
f(x) = 1/3x + 1
Step-by-step explanation:
slope-intercept form is
f(x) = mx + b
so just put the points in and you have:
f(x) = 1/3x + 1
also b stands for the y-intercept so if you look at your point (9,1) than your y-intercept would be 1.
hope I could help!!
Answer:`13H
Step-by-step explanation:
Answer:
The final estimate of √388 is 20.
Step-by-step explanation:
The number provided is:
<em>x</em> = 1388
Estimate the square root of 1388 as follows:
15² = 225
16² = 256
17² = 289
18² = 324
19² = 361
20² = 400
So, we now know that the square root of 388 lies between 19 and 20.
Check for 19.5²:
19.5² = 380.25
Check for 19.6²:
19.6² = 384.16
Check for 19.7²:
19.7² = 388.09 ≈ 388
The square root of 388 is closer to 19.7 or is approximately 20.
Thus, the final estimate of √388 is 20.
Answer: 24 m
Step-by-step explanation:
Given: area of the circle is 144 π m² .
Area of a circle =
, where r= radius of the circle.
Then, ![144\pi = \pi r^2](https://tex.z-dn.net/?f=144%5Cpi%20%3D%20%5Cpi%20r%5E2)
Cancelling π from both sides , we get
![144 = r^2](https://tex.z-dn.net/?f=144%20%3D%20r%5E2)
Taking square root on both sides , we get'
![12= r](https://tex.z-dn.net/?f=12%3D%20r)
i.e. radius = 12 m
Then diameter = 2 (radius ) = 2 (12)= 24 m
Hence, the diameter of the circle is 24 m.
