lora16 [44]

Answer:

There is a typo near the equal sign.

There can be two different answers if we think that = sign as + or -.

First way: Making = as +

=> 10 - [14 + (3+4) x 2] +3

=> 10 - [14 + 7 x 2] + 3

=> 10 - [14 + 14] + 3

=> 10 - 28 + 3

=> 10 + 3 - 28

=> 13 - 28

=> -15

=> So, -15 is the answer if we consider "=" sign as "+" sign.

Second way: Making = as -

=> 10 - [14 - (3+4) x 2] + 3

=> 10 - [14 - 7 x 2] + 3

=> 10 - [14 - 14] + 3

=> 10 - 0 + 3

=> 10 + 3

=> 13

=> So, 13 is the answer if we consider "=" sign as "-" sign.

T=17.4\sqrt[4]{m}
Differentiate with respect to time s:
\frac{dT}{ds}=\frac{17.4}{4m^{3/4}}\frac{dm}{ds}
⇒\frac{dT}{ds}=\frac{4.35}{m^{3/4}}\frac{dm}{ds}
Plug in m=38 and \frac{dm}{ds}=0.2:
\frac{dT}{ds}=\frac{4.35}{38^{3/4}}*0.2
