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>

(15 -3) ÷ 4 ⋅ 7 - 4² ÷ 4 = ?<br><br> Im struggling with pemdas! With this question especially!
Doss [256]

So here's PEMDAS:

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

So we will complete this equation in that order. So first is solving the problem within the <u>parenthesis:</u>

<em>(12)</em> ÷ 4  · 7 - 4² ÷ 4 =?

Then we solve all the parts including an <u>exponent:</u>

12 ÷ 4 · 7 - <em>16</em> ÷ 4 = ?

Next, we solve the parts with<u> multiplication: </u>

12 ÷ <em>28</em> - 16 ÷ 4 = ?

Then, we solve for all the <u>division:</u>

<em>0.43</em> - <em>4</em> = ?

If there was any addition we would do that next, but because there is none, we move onto<u> subtraction:</u>

0.43 - 4 = -3.57

So, your <u>answer</u> is -3.57
