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:
a variable is a placeholder.
Step-by-step explanation:
<span>Could you please mark as brainliest? Number of defective blue toys = 0.04 * 500 = 20
Number of defective red toys = 0.04 * 500 = 20
40 defective blue and red toys
Probability = 40 / 2500...which simplifies to
2 / 125 if you want your answer as a fraction
or
1.6% if you want a percentage
or
0.016 if you want a decimal</span>
