Answer:

5

Step-by-step explanation:

Since the question is " solve for 15/k when k=3", the question is simply asking you to divide ("/" is the divide sign, but it can get easily confused with the fraction sign). So, 15/3=5.

3. a) p∝1/m
P=k/m
48=k/9
48×9=k
k=432

the equation is: p=432/m

b) p∝1/m
P=k/m
P=432/12
P=36

Temka [501]

Using the slope concept, it is found that the rate of download of the file is of 1920 MB/s.

<h3>What is the slope?</h3>

The slope of a linear function is given by the <u>change in the output divided by the change in the input</u>.

In this problem:

  • 3 minutes since resuming the download 6720 total MegaBytes (MB).
  • 5 minutes since resuming the download 10560 total MegaBytes (MB) of the file had been downloaded..
  • Hence, in 2 minutes, there was a change of 10560 - 6720 = 3840 MB, which means that the slope is:

m  = \frac{3840}{2} = 1920

The rate of download of the file is of 1920 MB/s.

Len [333]

Answer:

D(t)=50\cdot (0.8)^{t}

Step-by-step explanation:

The equation for exponential decay function is given as:

D(t)=a(1-r)^{t}

where:

D(t)= difference in temperature t=time

r=rate of change

a =initial value of the temperature

From the given problem:

Initial Temperature,a=50°C

Rate of Decay,r=\frac{1}{5}

Therefore the function for the difference in temperature is given as:

D(t)=50(1-\frac{1}{5})^{t}

D(t)=50\cdot (\frac{4}{5})^{t}

We can convert \frac{4}{5} to decimal and write the function as:

D(t)=50\cdot (0.8)^{t}
