Answer:
Step-by-step explanation:
I don’t think I can type exponents here so I’ll write it and take a picture
Answer:
M = (Y2 - Y1) / (X2 - X1)
Step-by-step explanation:
First, look at a graph of a line and find two points, 1 and 2. You can use any two points on a line. The slope will be the same between any two points on a straight line.
Note the X and Y value for each of the points.
Now we'll designate the X and Y value for points 1 and 2. We'll use subscripts to identify them in the slope formula.
Hope this helps!
So convert all to same denominator by multiplying the denominator and numerator by 24.
Then just add the numerators as norma
Solution given:
R=rate=20%
T=time=45days =1month and 15 days =1 ½ months=⅛years
P=Principal=$31000
since bank gives/takes compound interest
so
interest=P((1+R/100)^T-1)
=31000((1+20/100)^⅛-1)=$714.6
