If A is the area of a circle with radius r and the circle expands as time passes, find dA/dt in terms of dx/dt
valina [46]
The area of a circle in terms of the circle's radius r is

A=\pi r^2

Differentiating both sides with respect to t, you get

\dfrac{\mathrm dA}{\mathrm dt}=2\pi r\dfrac{\mathrm dr}{\mathrm dt}

Find each measurement indicated. Round your answers to the nearest tenth.
Crazy boy [7]

Answer:

A

Step-by-step explanation:

Find AB using the Law of Sine:

\frac{AB}{sin(C)} = \frac{AC}{sin(B)}

Thus:

\frac{AB}{sin(40)} = \frac{47}{sin(103)}

Multiply both sides by sin(40)

\frac{AB}{sin(40)}*sin(40) = \frac{47}{sin(103)}*sin(40)

AB = \frac{47*Sin(40)}{sin(103)}

AB = 31.0056916 ≈ 31.0 cm (nearest tenth)

Find the inverse, g−1(x), of the following function: g(x) = 4x - 11
Sphinxa [80]

Answer:

g^{-1} (x) = \frac{x+11}{4}

Step-by-step explanation:

let y = g(x) and rearrange making x the subject, that is

y = 4x - 11 ( add 11 to both sides )

y + 11 = 4x ( divide both sides by 4 )

\frac{y+11}{4} = x

Change y back into terms of x , with x = g^{-1} (x) , thus

g^{-1}(x) = \frac{x+11}{4}
