First you need to find the slope of the line using the given coordinates of the two points.
The slope of the line = (1-4)/(4-3) = -3
Then you choose one pair of the coordinates given, either (3,4) or (4,1) , up to you, to find the equation of the line.
If you choose (3,4)
Then
(y-4)/(x-3) = -3
(y-4) = -3x+9
y = -3x+13
If you choose (4,1),
Then
(y-1)/(x-4) = -3
y-1 = -3x+12
y = -3x+13
So, F(x)=-3x+13
Answer:
80.78°
Step-by-step explanation:
When the 30 cm long string will be bent in the form of a sector it's two sides will be radii of the sector and lower part be the arc. Length of the arc can be found as given below.
Length of the string = 30 cm
radius of sector (r)= 8.8 cm
Length of the arc (l) = 30 - 2*8.8 = 30 - 17.6 = 12.4 cm
Let the sector makes angle at the centre of the circle.
Formula for length of arc of a sector is given as:
Plugging the values of l and r in the above formula, we find:

1 / 7*7*7*7*7*7
Reason
Multiply the exponents (3*-2) gives you 7^-6
A negative exponent flips to the positive fraction that is your answer
