PLEASE HELP!!! I'M ON A TIMER!! (20 POINTS) Which method correctly solves the equation using the distributive property? Negative

0.2 (x minus 4) = negative 1.7 Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x minus 4 = negative 1.7. Negative 0.2 x = 2.3. x = negative 11.5. Negative 0.2 (x minus 4) = negative 1.7. x minus 4 = 0.34. x = 4.34. Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x + 0.8 = negative 1.7. Negative 0.2 x = negative 2.5. x = 12.5. Negative 0.2 (x minus 4) = negative 1.7. Negative 0.2 x minus 0.8 = negative 1.7. Negative 0.2 x = negative 0.9. x = 4.5.

If a snowball melts so that its surface area decreases at a rate of 5 cm2/min, find the rate at which the diameter decreases whe
mixas84 [53]

Answer:

The diameter decreases at the rate of 0.0796 cm/min when the diameter is 10 cm.

Step-by-step explanation:

A snowball is spherical, so it's area is given by the following formula:

A = 4\pi r^{2}

The radius is half the diameter so:

A = 4\pi (\frac{d}{2})^{2}

A = 4\pi \frac{d^{2}}{4}

A = \pi d^{2}

If a snowball melts so that its surface area decreases at a rate of 5 cm2/min, find the rate at which the diameter decreases when the diameter is 10 cm.

We have to find \frac{dd}{dt} when \frac{dA}{dt} = -5, d = 10

A = \pi d^{2}

Applying implicit differentiation:

We have to variables(A and d), so:

\frac{dA}{dt} = 2\pi d \frac{dd}{dt}

-5 = 2\pi (10) \frac{dd}{dt}

\frac{dd}{dt} = -\frac{5}{20\pi}

\frac{dd}{dt} = -0.0796

The diameter decreases at the rate of 0.0796 cm/min when the diameter is 10 cm.
