This is something you memorize, have on a reference sheet/table, or use the unit circle.
Note: pi/4 radians = 45 degrees
Answer:
Where are the questions?
Step-by-step explanation:
A= πr^2
r=9
A= π(9)^2
A= 9x9=81
A=81π
In case that you have to use π
Multiply π(3.14)
3.14 times 81=254.34
Hello : let f(x) = ax
f(5) = 5a
f(3) = 3a
f(5)-f(3) =10 : 5a-3a = 10
2a = 10 so : a = 5
f(x) = 5x
f(10) -f(2) = 50-10 = 40
Answer:
The slope is m=1, y=1x-2
Step-by-step explanation:
Therefore, the slope is 1/1 so 1.
