Y= 2x^3 - 15x^2 + 36x - 20 find turning points and show working out
Murljashka [212]

Given:

The function is:

y=2x^3-15x^2+36x-20

To find:

The turning points.

Solution:

We have,

y=2x^3-15x^2+36x-20

Differentiate the given function with respect to x.

y'=2(3x^2)-15(2x)+36(1)-(0)

y'=6x^2-30x+36

y'=6(x^2-5x+6)

For turning point, y'=0.

6(x^2-5x+6)=0

x^2-3x-2x+6=0

x(x-3)-2(x-3)=0

(x-3)(x-2)=0

Using zero product property, we get

x-3=0 and x-2=0

x=3 and x=2

Therefore, the turning points of the given function are at x=2 and x=3.

The population of a city has been increasing by 2% annually. In 2000, the population was 315,000. Predict the population of the
Minchanka [31]

Answer:

The population of the city in 2020 is 3,839,832

Step-by-step explanation:

Given:

Population at 2000 =  315,000

Rate at which the population increases = 2%

To Find:

The Population in the city after 2020 = ?

Solution:

The population in the city after 2020 can be found by using Exponential growth function.

Exponential growth occurs when a quantity increases by the same factor

Exponential growth function is y = a(1 + r)^t

Where

y is the final amount

a is the initial amount

r is the rate of  increase

t is the time period.

Now substituting the values ,

In 2020 i.e., after 10 years

y = 315000(1 + 2 \%)^{10}

y = 315000(1 + \frac{2}{100})^{10}

y = 315000(1 + 0.02)^{10}

y = 315000(1.02)^{10}

y = 315000\times 1.218

y = 3,839,832.42
