Answer:
About 6,785 people will be infected about nine months.
Step-by-step explanation:
We can write an exponential function to represent the situation. The standard exponential function is given by:
Where <em>a</em> is the initial value, <em>r</em> is the rate, and <em>x</em>, in this case, is the time that has passed in months.
3,124 people have already been infected. Thus, our initial value <em>a</em> = 3124.
And an additional 9% will be infected per month. Therefore, our rate <em>r</em> will be 1 + 9% or 1.09.
Hence, our function is:
Then after nine months, the total amount of infected people will be f(9):
Use a calculator:
About 6,785 people will be infected about nine months.
Hello and Good Morning/Afternoon:
<u>Let's take this problem step-by-step</u>:
<u>What does the problem want us to find:</u>
<u>Let's gather the information</u>:
⇒ the information given: y = 1/5 x - 8
⇒ the line is in <u>slope-intercept form</u>
⇒ means:
⇒ coefficient in front of 'x' is the slope
⇒ constant is the y-intercept
- slope is 1/5
- y-intecept is -8
<u>Answer:</u>
- <u>Slope is 1/5</u>
- <u>y-intercept is -8</u>
<u></u>
Hope that helps!

Answer:
The sum of all integers is 774.
Step-by-step explanation:
Since √11 = 3.3166, and 3.3166 is not an integer, so the first integer is 4.
From 1 to 39, there are 39 integers. But we started with 4, so we take out 3 numbers (1, 2, 3). Therefore, there are 39 - 3 = 36 numbers left.
The total number between 4 and 39 is 36 = n.
Sn = n/2 x (a1 + an)
S36 = 36/2 x (4 + 39) = 18 x 43 = 774
