Answer:

a) The Expectation of the Population to grow in the next year

= 3069

b) The Expectation of the Population decrease in the next year

= 12,467

Step-by-step explanation:

Explanation:-

The population of Boom town is currently 3000

Given expected to grow by 2.3 % over the next year

= $3000 X \frac{2.3}{100} = 69$

= 69

The Expectation of the Population growth in the next year

= 3000 +69 = 3069

The population of town is currently 13000

Given expected to grow by 4.1 % over the next year

= $13000 X \frac{4.1}{100} = 533$

The Expectation of the Population decrease in the next year

= 13000 - 533 = 12,467

Determine the value of y if x is 11 Y=|x-5|

Degger [83]

The answer is 6.

Absolute value works like this:

If you have just a number inside the bars, then it's positive. If the negative sign is inside the bars, it's still positive. If the negative sign is outside the bars, regardless of what's inside the bars, then it's negative.

Basically, you are adding, because absolute values are positive, unless you have a minus sign outside the absolute value, so 6+5=11.

What you do is this:

y = |x - 5|

y = x + 5

y = 11 + 5

y = 6

Consider the relation y=x^3+2x^2-9x+18/x+3

Ivahew [28]

Answer:

a) $y=\frac{x^{3}+2x^{2} -9x+18}{x+3}$ .

Substitute all the values in the given relation.

The steps and table is attached below.

b) The relation is not a function.

Since the x =0 and x=3 has the same value. A relation is function when each input has only exact one output. refer the on-to diagram uploaded.

c) The domain is the set of all input values that can be applied into a function y or f(x).

Here all the x values -4,-3,-,-1,0,1,2,3,4 [-4,4] is the domain.

Factor using the identity: a3 + b3 = (a + b)(a2 – ab + b2) 8z3 + 27

vivado [14]

Answer: this is our required factor i.e.

$8z^3+27=(2z+3)(4z^2-6z+9)$

Explanation:

Since we have given that

$8z^3+27$

As we know the identity , which says that

$a^3+b^3=(a+b)(a^2-ab+b^2)$

So, we can use this here ,

$8z^3+27=(2z)^3+3^3\\\\=(2z+3)((2z)^2-2z\times 3+3^2)\\\\=(2z+3)(4z^2-6z+9)$

Hence this is our required factor i.e.

$8z^3+27=(2z+3)(4z^2-6z+9)$

Solve for the unknown.*

xenn [34]

Answer:

13.14

Step-by-step explanation:

sin 37.5 deg = 8/x

x = 8/sin 37.5 deg

x = 13.14

(I was thinking about it as a right angled triangle although the qn did not specify but idt you can solve it by using sine / cosine rule so TOA CAH SOH may be the only one and the most direct method to solve it)
