Answer:
-14
Step-by-step explanation:
difference between -20 and -5 = 15
15 x 2/5 = 30/5 = 6
-20 + 6 = -14

Answer:
y = 8º
y = 8º
Step-by-step explanation:
Given:
(10x - 61)º
(18y + 5)º
(x + 10)º
Find:
x and y
Computation:
(10x - 61) + (x + 10) = 180
11x - 51 = 180
11x = 231
x = 21º
(10x - 61)º = (18y + 5)º [Vertical opposite angle]
10x - 61 = 18y + 5
10x - 18y = 66
5(21) - 9y = 33
y = 8º

Answer:
dy/dx = x^sin(x) * (sin(x)/x + cos(x) * lnx)
Step-by-step explanation:
∵ y = x^sin(x)
∴㏑y = ㏑(x^sin(x)) = sinx * ㏑x --- by differentiating both sides with respect to x
(1/y)* dy/dx = sin(x)/x + cos(x) lnx
dy/dx = x^sin(x) * (sin(x)/x + cos(x) * lnx)
