Answer:
-6.3 degrees
Step-by-step explanation:
First I formed the equation 10.4-16.7=x, which the answer came to be -6.3 degrees.
Answer:
v₁ = 2.5; v₂ = 0.5.
Step-by-step explanation:
4v² + 8v + 5 = 10
4v² + 8v + 5 - 10 = 10 - 10
4v² + 8v - 5 = 0
D = 8² - 4 · 4 · (-5) = 64 + 80 = 144

Conversion Formula: Radian/π = Degree°/180°
R= 7π/4, Degree =?
Apply the formula:
So [(7π/4) / π = Degree / 180] (note that 7π/4) / π = 7/4)
Degree = (7/4) x 180° = 315°
Consider c as the cost of the widget so that our given equation is
c = 0.1w^2 + 20w
Take the derivate of the equation.
d/dt (c = 0.1w^2 + 20w)
dc/dt = 0.2w + 20
Given dc/dt = $16000 per month, the number of widgets would contain:
16000 = 0.2w + 20
-0.2w = 20 - 16000
-0.2w = -15980
w = 79900 widgets
