Answer:

f(-1) = 2

Step-by-step explanation:

To evaluate this function at x = -1, replace "x" in the equation with (-1) (you should use the parentheses as indicated here).

f(x)=x²-3x-2 becomes

f(-1)=(-1)² - 3(-1) -2, or

f(-1) = 1 + 3 - 2, or

f(-1) = 2

The student body president of a high school claims to know the names of at least 1000 of the 1800 students who attend the school
natali 33 [55]

Answer: Population = Total students attend the school.

Parameter = Proportion of students named by president correctly.

Step-by-step explanation:

Population for a particular study is the largest possible group of individuals that are essential to be considered.

Parameter = measure of characteristic in a population.

By the above definition, we have

Population = Total students attend the school(1800).

Parameter = Proportion of students named by president correctly.

Bernoulli equation <br> xy’+3y=x^5y^(1/3)<br> Please solve this step by step
s344n2d4d5 [400]

Answer:

y=(x^5/8+Cx^{-3})^{3/2}

Step-by-step explanation:

xy’+3y=x^5y^(1/3)

rewrite in:

y^{-1/3}\frac{dy}{dx} +3x^{-1}y^{2/3}=x^4

substitute: v=y^{2/3}\\

\frac{dv}{dx}=\frac{d}{dx}y^{2/3}=y^{-1/3}\frac{dy}{dx}

The equation can be rewritten in:

\frac{dv}{dx}+3vx^{-1}=x^4

This is a first-order linear differential equation:

Can be solved by using integrating factor or variation of parameter:

integrating factor:

u(x)=exp(∫3/x \ dx) = x^3

v=u^{-1}∫u(x) x^4dx

v=x^{-3}(∫x^4x^3dx)

y^{2/3}=v=x^{-3}(x^8/8+C)

y=(x^5/8+Cx^{-3})^{3/2}
