Answer:
= 
, so the model car is moving away from the fixed point at a rate of approximately 1.7 feet per second.
Step-by-step explanation:
The functions x and y satisfy (x−20)^2+y^2=25 and differentiating gives 2(x−20)dx/dt+2y dy/dt=0. Substituting the three known values and solving for dy/dt yields dy/dt=−32. Since Z=x^2+y^2−−−−−−√, dZ/dt=(2x ^ dx/dt+2y^dy/dt) / 2x2+y2√. Substituting Since Substituting for x, y,
, and 
gives = ,
Answer:
the answer would be B
Step-by-step explanation:
for the slope you would need to count up then over between the two points and do that until you reach where the line crosses or in this case would cross for the y-intercept
Make them both over 54:
so 7/9= 42/54
and 5/6= 35/54
now you can easily see that 7/9 is larger than 5/6
Answer:
$1,640,070
Step-by-step explanation:
Cost of goods sold = (starting inventory) +(production) -(ending inventory)
= $630,750 +1,682,900 -673,580
= $1,640,070
The cost of goods sold for the year was $1,640,070.
