Do your variables first. So, I think 7a × 2a= 14a and then 2 × 4 = 8

Final answer is probably 14a8

Answer:

The correct answer is ,7a ² x 2a⁴ = 14a⁶

Step-by-step explanation:

Identity:-

mᵃ x mᵇ = m⁽ᵃ⁺ᵇ⁾

It is given that,7a ² x 2a⁴

<u>To find simplified form of 7a ² x 2a⁴</u>

7a ² x 2a⁴ = (7 x 2) x a² x a⁴

a² x a⁴ = a⁽²⁺⁴⁾ a⁶

7a ² x 2a⁴ = 14a⁶

Therefore the simplified form of 7a ² x 2a⁴ = 14a⁶

webassign If a snowball melts so that its surface area decreases at a rate of 6 cm2/min, find the rate at which the diameter dec

drek231 [11]

Answer:

The answer is $\frac{3}{10\pi } cm/min$

Step-by-step explanation:

Assuming the snowball is a perfect sphere, then if A denotes the surface area and D the diameter then:

$A=4\pi r^{2} = 4\pi (\frac{D}{2} )^{2} =\pi D^{2}$

Differentiating wrt r we have:

$\frac{dA}{dD} =2\pi D$

We are told that $\frac{dA}{dt}= -6$ and we want to find $\frac{dD}{dt}$

By the chain rule we have:

$\frac{dA}{dD}=\frac{dA}{dt}.\frac{dt}{dD}=\frac{\frac{dA}{dt} }{\frac{dD}{dt} }$

∴ $2\pi D=-\frac{6}{\frac{dD}{dt} }$

∴ $\frac{dD}{dt}=-\frac{6}{2\pi D}$

When D=10 then

$\frac{dD}{dt} =-\frac{6}{10*2\pi } =-\frac{3}{10\pi }$

The sign (-) shows that the D is decreasing.
