Answer: $159.2\ cm^3$

Step-by-step explanation:

The volume of cone is given by :-

$\text{Volume}=\frac{1}{3}\pi r^2h$

Given: The diameter of paper cups = 8 cm

Thus, the radius of paper cup (r)= $\frac{8}{2}=4\ cm$

The height of paper cup (h)= 9.5 cm

Now, the volume of paper cup will be :-

$\text{Volume}=\frac{1}{3}\pi (4)^2(9.5)\\\\\Rightarrow\text{Volume}=\frac{1}{3}(3.14159265359)\times(16)(9.5)=159.174027782\approx159.3\ cm^3$

Hence, the best approximation for the volume of the paper cup $159.2\ cm^3$

Verify that P = Ce^t /1 + Ce^t is a one-parameter family of solutions to the differential equation dP dt = P(1 − P).

NemiM [27]

Answer:

See verification below

Step-by-step explanation:

We can differentiate P(t) respect to t with usual rules (quotient, exponential, and sum) and rearrange the result. First, note that

$1-P=1-\frac{ce^t}{1+ce^t}=\frac{1+ce^t-ce^t}{1+ce^t}=\frac{1}{1+ce^t}$

Now, differentiate to obtain

$\frac{dP}{dt}=(\frac{ce^t}{1+ce^t})'=\frac{(ce^t)'(1+ce^t)-(ce^t)(1+ce^t)'}{(1+ce^t)^2}$

$=\frac{(ce^t)(1+ce^t)-(ce^t)(ce^t)}{(1+ce^t)^2}=\frac{ce^t+ce^{2t}-ce^{2t}}{(1+ce^t)^2}=\frac{ce^t}{(1+ce^t)^2}$

To obtain the required form, extract a factor in both the numerator and denominator:

$\frac{dP}{dt}=\frac{ce^t}{1+ce^t}\frac{1}{1+ce^t}=P(1-P)$

Determine the value c so that each of the following

Levart [38]

This can help you

a) since it is discrete we need to think about the sum thing it it was continuous we would look at an integral thing so I think if I remember correctly we need to find c such that ∑i=03c(x2+4)=1
b) problem b is a similar setup
