For f composite g, plug g into f
f(g)=6x^2+3
-3. -3
-3=6x^2
—. ——
6. 6
-3/6=x^2
square root of -3/6=x
then plug that number into
g composite f
f(f)=6(square root of /3/6)

A particle moves along the curve y=7 x 2+4y=7 x 2+4 in such a way that its xx-coordinate is changing at a rate of −5−5 centimete

ArbitrLikvidat [17]

Answer:

The y-coordinate is changing by the rate of -70 cm per sec.

Step-by-step explanation:

Given equation,

$y = 7x^2 + 4$

Differentiating with respect to time (t),

$\frac{dy}{dt}=14x \frac{dx}{dt}$

We have,

$\frac{dx}{dt}=-5\text{ cm per sec}, x = 1$

$\frac{dy}{dt} = 14(1)(-5)=-70\text{ cm per sec}$

Which equation is equivalent to 2x + 6y = 12?

vlada-n [284]

2x + 6y = 12
6y = -2x + 12
y = -2x/6 + 12/6
y = -1/3 x + 2
