solong [7]

Answer:

a) $P(t) = 22000(1.071)^{t}$

b) The population increases 7.1% each year.

Step-by-step explanation:

The continuous population growth model is given by:

$P(t) = P_{0}(1+r)^{t}$

In which $P(t)$ is the population after t years, $P_{0}$ is the initial population and r is the growth rate.

In this problem, we have that:

A population grows from its initial levelof 22,000 at a continuous growth rcte of 7.1% per year.

This means that $P_{0} = 22000, r = 0.071$

a) Write a function to model the population increase.

$P(t) = 22000(1 + 0.071)~{t}$

$P(t) = 22000(1.071)^{t}$

b) By what percent does the populaiion increase each year?

$r = 0.071$

So the population increases 7.1% each year.

Math riddle! Correct answer gets brainliest! Answer with what x and y are equal to.

RSB [31]

Answer:

$\displaystyle [9, 4\frac{1}{2}]$

Step-by-step explanation:

I figure these exercises out by numeric association. I see a 3, so I know right away that there might be a 9 somewhere. So, you start by plugging 3 in for $\displaystyle x,$ THEN plug $\displaystyle 1\frac{1}{2}$ in for $\displaystyle y$ sinse there are twise the quantity of $\displaystyle y$ than there are of $\displaystyle x.$ Now, doing so will give you $\displaystyle 24 ≠ 18.$ This tells you to try another pattern, so go with plugging $\displaystyle 4\frac{1}{2}$ in for $\displaystyle y$ and $\displaystyle 9$ in for $\displaystyle x$ . Doing so gives you what you are looking -- $\displaystyle 36 = 36.$ Therefore, the association wourked perfectly. ☑

A number x, rounded to 1 decimal place is 12.3 write down the error interval for x

icang [17]

We know that
A number x, rounded to 1 decimal place is 12.3
so
x>=12.25
and
x < 12.35

the error interval for x is the interval [12.25,12.35)

the answer is
[12.25,12.35)
