Answer: 20,532

Step-by-step explanation:

17,400(.02)=348

348(9)=3132

17,400+3132=20,532

Answer:

Step-by-step explanation:

This is an exponential growth function of the form:

y=ab^x where a is the initial population and b is the growth rate. This could also be written as

y=a(1+r)^x which is a bit more accurate. We'll use that one. r is the percent growth: 2% for us.

Filling in the formula:

y=17400(1+.02)^x and then simplifying:

y=17400(1.02)^x

That's the model for this population. Filling in any number of years for x will give you the population y. Our time is 9 years:

y=17400(1.02)^9

Take care of the exponents first, giving us:

y=17400(1.195092569) and then multiply to get

y = 20,794.6 or 20,794 people (since you can't have 6/10 of a person)

Can you find the slope for me, please?
shusha [124]
The slope is -3/2

Use the two ordered pairs (-2,0) and (0,-3) and do y2-y1/x2-x1

-3-0/0+2= -3/2

What is the value of x in the figure? <br><br><br> x= ?
Otrada [13]
X = 68

Since the angle opposite of it is a right angle, we know that 22 + x has to equal 90 also. 

So just take 90 - 22 = 68 degrees

Write the polynomial function with the given zeros.<br> 5. x= -1,-1, 6
Allushta [10]

Answer:

Step-by-step explanation:

There are many such polynomials, but the one with leading coefficient of 1 is

y = (x+1)(x-1)(x-6) = x^3 - 6x^2 - x + 6

Not sure what you want to do with the 5, If that is the y-intercept, then since

(1)(-1)(-6) = 6, we will need

y = 5/6 (x^3 - 6x^2 - x + 6)
