Answer: 66 is the circumference
Step-by-step explanation: Formula of circumference: 2 times pi times R
R is radius and Diameter is 2 times of R. Formula of circumference can also be: pi times R. 22/7 times 21 is 66.
Answer:
Step-by-step explanation:
well i guess if the decimal is on the left you would move it to the right twice
because if you only moved it once it'd become 1.0
and if you moved it to the left once it would also become 1.0
and if you moved it twice to the left you would be left with .10
pls mark me brainliest
Answer:
Step-by-step explanation:
Required
The positive root of 
Equate to 0
So, we have our function to be:
Differentiate the above function:
Using Newton's method of approximation, we have:
Plot the graph of to get 
--- see attachment for graph
From the attached graph, the first value of x is at 2.2; so:
So, we have:
The process will be repeated until the digit in the 6th decimal place remains unchanged
Hence:
Answer:
y = -2x - 8
Step-by-step explanation:
<u>Use the point slope form: (y - y1) = m(x - x1)</u>
(y - (-4)) = -2(x - (-2))
y + 4 = -2(x + 2)
y + 4 - 4 = -2x - 4 - 4
y = -2x - 8
Answer: y = -2x - 8
