Answer:
1/4
Step-by-step explanation:
y2-y1/x2-x1=m
6-5/9-5=1/4
Answer:

Step-by-step explanation:
Given the differential (d/dx)(cos−1(x)), to find the equivalent formula we will differentiate the inverse function using chain rule as shown below;
let;


Therefore;

Since x = cos y from the above substitute;

Hence,
gives the required proof
It would take about 4 days because for one day he can paint half a painting. there are 4 halves in 2 wholes so it would take 4 days

Hi there
The function is
Y (x)=10000 (1-0.02)^x
Y (x)=10000 (0.98)^x
Where x is the number of time
