First make it improper fraction :
6/5 + 17/5
Then add 6 and 17 :
23
The denominator doesn’t change :
So the answers is 23/5

Then you need to simplify it
How much times 5 goes in 23 :
4 times and 3 extra
So the FINAL ANSWER is : 4 3/5

Differentiate with respect to t
True [87]

Answer:

\displaystyle 2x\frac{dx}{dt}-3y^2\frac{dy}{dt}+4z^3\frac{dz}{dt}=0

Step-by-step explanation:

We want to differentiate the equation:

x^2-y^3+z^4=1

With respect to <em>t</em>, where <em>x, y, </em>and <em>z</em> are functions of <em>t. </em>

<em />

So:

\displaystyle \frac{d}{dt}\left[x^2-y^3+z^4\right]=\frac{d}{dt}\left[1\right]

Implicitly differentiate on the left. On the right, the derivative of a constant is simply zero. Hence:

\displaystyle 2x\frac{dx}{dt}-3y^2\frac{dy}{dt}+4z^3\frac{dz}{dt}=0

Do you expect δhsoln to be a large positive number, a large negative number, or close to zero? do you expect to be a large posit
strojnjashka [21]

Answer:

δhsoln will be close to zero.

Step-by-step explanation:

In calculus, the symbol d represents a large or significant increment in a value. For example, say the change in the volume of a liquid in a tank depends upon the change of the height h.

The above statement can be written like this:

dV/dh

This means that the volume of the tank (V) depends with a significant change in the height of the liquid (h).

It is also possible to compute small changes in physical quantities. The symbol δ simply presents a small increment or small change. Using the same expression above, if a very large tank was to have a very very small leak, the change would be: δV/δh

In other words, the change in the volume will be almost negligible and will be close to zero.

Mariulka [41]

nearest cent so so 32.86 but since its money and 32.86 times 7 is 230.02 it should be rounded down so the answer will be 32.85
