Answer:
Expression Derivatives
y = tan-1(x / a) dy/dx = a / (a2 + x2)
y = cot-1(x / a) dy/dx = - a / (a2 + x2)
y = sec-1(x / a) dy/dx = a / (x (x2 - a2)1/2)
y = cosec-1(x / a) dy/dx = - a / (x (x2 - a2)1/2)
Point w is at (-4,0) and z is at (0,-5). the segment WZ is one side of the square. the distance from W to Z is√(-4²+5²)=√41. the perimeter is then 4√41 or approx 25.6
Answer:
104
Step-by-step explanation:
more than just means addition, unless dealing with inequalities.
Answer:
87 degrees
Step-by-step explanation:
9x+6 + 7x-2 = 148
16x+4 = 148
16x = 144
x = 9
Plug into 9x+6
9(9)+6 = 87
ABC = 180 degrees because a triangle is always equal to 180degree
