y-2=3/2 (x+1) must be first
By the pythagorean theorem we know that.
s2 = r2 + h. ...
since r = a/2.
s2 = (1/4)a2 + h2, and.
s = √(h2 + (1/4)a2)
This is also the height of a triangle side.
I don’t know the answer but this might help.

Answer:
Step-by-step explanation:
Given the expression that represents the situation where Alex and Janet have read the same number of books as
4m = m-1
where m represents the number of months Janet has been reading books,
To calculate m
STEP 1: subtract m from both sides
4m - m = -1
3m = -1
Step2; divide both sides by 3
3m/3 = -1/3
m = -1/3
Hence the value of m is -1/3
Answer:
a) 4
Step-by-step explanation:
Take the equation:
x + 1483 = 2113.833
Solve for x:
x = 2113.833 - 1483
x = 630.833
To find df, take the equation:
![\frac{x}{y} = 210.2778](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%20%3D%20210.2778)
Where x = 630.833
![\frac{630.833}{y} = 210.2778](https://tex.z-dn.net/?f=%20%5Cfrac%7B630.833%7D%7By%7D%20%3D%20210.2778%20)
Solve for y:
![y = \frac{210.2778}{630.833}](https://tex.z-dn.net/?f=%20y%20%3D%20%5Cfrac%7B210.2778%7D%7B630.833%7D%20)
![y = 2.9999](https://tex.z-dn.net/?f=%20y%20%3D%202.9999%20)
y ≈ 3
Take number of treatments = k
Degrees of freedom, df, of numberof treatments = k - 1
Therefore,
Where df = 3, we have:
k - 1 = 3
Solve for k:
k = 3 + 1
k = 4
The number of treatment groups is 4
