\frac{dw}{dt}  =  \frac{dx}{dt} \times  \frac{dw}{dx}   +  \frac{dy}{dt} \times  \frac{dw}{dy}   +  \frac{dz}{dt} \times  \frac{dw}{dz}   \\  \frac{dw}{dt}  = 3t ^{2}  \times  {e}^{ \frac{y}{z} }  +  - t \times  \frac{x {e}^{ \frac{y}{z} } }{z}  + 4 \times  -  \frac{xy {e}^{ \frac{y}{z} } }{ {z}^{2} }   \\  \frac{dw}{dt}  =  \frac{ {e}^{ \frac{y}{z} } (3 {t}^{2} {z}^{2}   - tzx - 4xy)}{ {z}^{2} }

Which set is closed under the operation multiplication?
oee [108]
I have another set of choices here:

A. {0.5, 1, 2} 


B. {1, 2, 4} 


C. {1, 2, 3, 4, 5} 


<span>D. {0} 
</span>
If you multiply two numbers from a closed set the answer is in the set. 
<span>So A is not closed because 2 x 2 = 4 which isn't in the set. Only 0.5, 1, and 2 are in set A. </span>

<span>Try multiplying the largest numbers in sets B, C, and D by themselves. You will soon discover the closed set.</span>

What number has a 9 with a value ten times as many as the 9 in 39,154
Tomtit [17]

Answer:

Any number with 9 in the ten-thousands place. 90,000 is one such number.

Step-by-step explanation:

The 9 in 39,154 is in the thousands place. Its value is 9,000. In order for the 9 in a number to have a value 10 times that, or 90,000, the 9 must be in the ten-thousands place.

There are an infinite number of such numbers. We suspect you have a list you are to choose from. Pick the number with 9 where it is in the number 90,000.
