Point: (-7,-4)
slope: 1/2
the equation given is in point slope form
(y-y1) = m (x-x1)
x1 and y1 are the coordinate points of an ordered pair
m is the slope
Answer:
Option C: (4.47,-0.46)
Step-by-step explanation:
To convert Cartesian coordinates into polar coordinates , use the following formulas:
Therefore:
Because (4,-2) is located in Quadrant II, the angle must also be located in Quadrant II. Therefore, the correct polar coordinate would be (4.47,-0.46)
Derivative of tan(x) is sec²x

Answer:
the perimeter of the field is 328 yards
Step-by-step explanation:
perimeter of a rectangle = 2(L+B)
where L= length = 108 yards
B = breadth = 56 yards
perimeter of a rectangle = 2(108 +56)= 328 yards
