A line parallel to x-axis has 0 slope.
Volume = 5*10*2 = 100 cm³
Densidade = massa / volume
Densidade = 700g / 100 cm³
Densidade = 7g/cm³
(7,1) is the correct answer
It already is in simplest form. In mixed fraction, it would be 9 1/7
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
=
