The number y of hits a new website receives each month can be modeled by y = 4070ekt, where t represents the number of months th

makvit [3.9K]

Answer:

<u><em>k = 0.2645</em></u>

Step-by-step explanation:

Given model:

y = 4070 $e^{kt}$

y = no. of hits website received = 9000 (in 3rd month)

t= no. of months website has been operational = 3

put in the above equation:

9000 = 4070 $e^{3k}$

$\frac{9000}{4070}$ = $e^{3k}$

$\frac{900}{407}$ = $e^{3k}$

<u><em>Taking natural logarithm on both sides, we get:</em></u>

$ln\frac{900}{407}$ = $ln(e^{3k})$

$ln\frac{900}{407}$ = 3k ln<em>e</em>

ln<em>e</em>=1

$ln \frac{900}{407}$ = 3k

or k = $\frac{1}{3}$ $ln\frac{900}{(407)}$

k = $\frac{1}{3}$ (0.7936)

<em>k = 0.2645</em>

SOVA2 [1]

Speed of Tim = 60 miles/hour

Speed of Joe = 45 miles/ hour

Distance = Speed x Time

A 3 hours, Tim had travelled 60 x 3 miles = 180 miles.

At 3 hours, Joe had travelled 45 x 3 miles = 135.

The difference between the distances is 45.

Therefore, they were 45 miles apart after 3 hours.

I hope this is right.
