Answer:
true
Step-by-step explanation:
Draw a number line from -10 to +10 with tick marks (division lines) every 1 unit. Now find the origin (in the middle of the line you have just drawn). Now move your pencil point 3 units to the left and plot a dark (closed) dot there. Then draw a ray from that closed dot to the left. Apparently we cannot extend that ray beyond -10.
(-10,-3] would be my representation of this situation.
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
Answer:
40
Step-by-step explanation:
14/35 = f/100
35f = 14 x 100
f = 14 x 100 /35
f = 40
