City planners anticipate an 8.2% population growth per year, including new residents and births. The population, in millions of

people, based on this increase can be modeled by the function p(x) = 2.5(1.082), where x is the number of years of tracked growth. The planners also estimate a 3% population loss over the same time period that can be modeled by the function L(p) = p(0.97).​

<h2>Hello!</h2>

The answer is:

The correct option is the third option,

L(p(x))=2.425(1.082)^{x}

<h2>Why?</h2>

From the statement we know the function that models the population growth over the years (p(x)) but we have been told that there is an estimated loss that can be modeled by the function L(p), so in order to find which function represents the final function, we need to composite the function, which is the same that evaluate p(x) into the function L(p).

We are given:

p(x)=2.5(1.082)^{x}

and

L(p(x))=p(0.97)

So, the evaluationg p(x) into L(p), we have:

L(p(x))=p(0.97)\\\\L(p(x))=2.5(1.082)^{x}*(0.97)=0.97*2.5(1.082)^{x} \\\\L(p(x))=0.97*2.5(1.082)^{x}=2.425(1.082)^{x}\\\\L(p(x))=2.425(1.082)^{x}

Hence, the correct option is:

The third option,  

L(p(x))=2.425(1.082)^{x}

Have a nice day!

The arc length of a sector is equal to four times the radius. Express the arc length s
Sveta_85 [38]

Answer:

Step-by-step explanation:

Given that,

The arc length is four times the radius

Let he radius be 'r'

Then, the arc length be 's'

The arc of a sector can be calculated using

s=θ/360 × 2πr

Then, given that s=4r

So, 4r = θ × 2πr / 360

Divide both side r

4 = θ × 2π/360

Then, make θ subject of formula

θ × 2π = 360 × 4

θ = 360 × 4 / 2π

θ = 720 / π

So, area of the sector can be determine using

A = θ / 360 × πr²

Since r = ¼s

Then,

A = (θ/360) × π × (¼s)²

A = (θ/360) × π × (s²/16)

A = θ × π × s² / 360 × 16

Since θ = 720 / π

A = (720/π) × π × s² / 360 × 16

A = 720 × π × s² / 360 × 16 × π

A = s² / 8

Then,

s² = 8A

Then,

s= √(8A)

s = 2 √2•A

Is the line segment 4x+2y=0 parallel?
qaws [65]
4x + 2y = 0
2y = -4x 
y = -2x...the slope here is -2

the above line ^^ is parallel to y = -2x + 3.....because parallel lines will have the same slope

The base of the isosceles triangle is five times the height<br><br> Find the exact value of cot ø
Vika [28.1K]

Answer:

The exact value of cot(∅) is 2.5

Step-by-step explanation:

The picture of the question in the attached figure

we know that

An isosceles triangle has two equal sides and two equal interior angles

In his problem

AB=BC

m\angle BAC=m\angle ACB=\phi^o

In the right triangle ABD

cot(\phi)=\frac{AD}{BD} ---> adjacent side angle ∅ divided by the opposite side angle ∅

we have

The base of the isosceles triangle is five times the height

so

b=5h

AD=\frac{b}{2}=\frac{5h}{2}\ units

BD=h\ units

substitute

cot(\phi)=\frac{(5h/2)}{h}=2.5
