Formula for Average rate of change :

A(x) = f(a) - f(b) / a - b

Solving :

A(x) = f(-2) - f(0) / -2 - 0
A(x) = 10 - 6 / -2
A(x) = 4/-2
A(x) = <u>-2</u>

Step-by-step explanation:

the average change rate is simply the change of the functional values in a given interval relative to the change of the input values.

in short

(f ( interval upper limit) - f (interval lower limit) ) /

(interval upper limit) - (interval lower limit)

and you know that f (x) is usually also called y (the functional result variable).

so, the upper limit is 0, the lower limit is -2.

y (or f (x)) is 6 and 10 at these points.

and we get

(6 - 10) / (0 - -2) = -4 / 2 = -2

Use the model below to estimate the average annual growth rate of a certain country's population for 1950, 1988, and 2010, where

Morgarella [4.7K]

Answer:

The average annual growth rate of a certain country's population for 1950, 1988, and 2010 are 2.398, 0.9985 and 0.2236 respectively.

Step-by-step explanation:

The given equation is

$Y=-0.0000084x^3+0.00211x^2-0.205x+8.423$

Where Y is the annual growth rate of a certain country's population and x is the number of years after 1900.

Difference between 1950 and 1900 is 50.

Put x=50 in the given equation.

$Y=-0.0000084(50)^3+0.00211(50)^2-0.205(50)+8.423$

$Y=2.398$

Therefore the estimated average annual growth rate of the country's population for 1950 is 2.398.

Difference between 1988 and 1900 is 88.

Put x=88 in the given equation.

$Y=-0.0000084(88)^3+0.00211(88)^2-0.205(88)+8.423$

$Y=0.9984752\approx 0.9985$

Therefore the estimated average annual growth rate of the country's population for 1988 is 0.9985.

Difference between 2010 and 1900 is 110.

Put x=110 in the given equation.

$Y=-0.0000084(110)^3+0.00211(110)^2-0.205(110)+8.423$

$Y=0.2236$

Therefore the estimated average annual growth rate of the country's population for 2010 is 0.2236.

2(4x - 1) + 3(3 - 2x) = 0

LUCKY_DIMON [66]

2(4x-1) + 3(3-2x)=0
distribute
8x-2+9-6x=0
add like terms
2x+7=0
subtract 7 from both sides
2x= -7
divide both sides by 2
x=-7/2
