Since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year. Predict th

BaLLatris [955]

Answer:

20,158 cases

Step-by-step explanation:

Let $t=0$ represent year 2010.

We have been given that since 2010, when 102390 Cases were reported, each year the number of new flu cases decrease to 85% of the prior year.

Since the flu cases decrease to 85% of the prior year, so the flu cases for every next year will be 85% of last year and decay rate is 15%.

We can represent this information in an exponential decay function as:

$F(t)=102,390(1-0.15)^t$

$F(t)=102,390(0.85)^t$

To find number of cases in 2020, we will substitute $t=10$ in our decay function as:

$F(10)=102,390(0.85)^{10}$

$F(10)=102,390(0.1968744043407227)$

$F(10)=20,157.970260446597\approx 20,158$

Therefore, 20,158 cases will be reported in 2020.

A line has the points (3,7) (4,9) (5,11) (6,13). If the slope is divided by 2, what is the new slope?

lorasvet [3.4K]

Answer:

The new slope is 1

Step-by-step explanation:

The slope of any two points can be found by:

$slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Finding slope of (3,7) (4,9)

$slope=\frac{9-7}{4-3}\\slope=\frac{2}{1}\\slope=2$

Finding slope of (4,9) (5,11)

$slope=\frac{11-9}{5-4}\\slope=\frac{2}{1}\\slope=2$

So, the slope of the line is 2

Now if slope is divided by 2, new slope will be:

$slope = \frac{2}{2}\\slope=1$

So, The new slope is 1
