Sindrei [870]

Answer:

As Doris Day said: Good morning to you

Answer 27/2

Step-by-step explanation:

f(x)=-x^3+5x\\F(x)=-\dfrac{x^4}{4} +\dfrac{5x^2}{2} \\F(2)=\dfrac{-16}{4}+\dfrac{20}{2}  =6\\\\F(-1)=\dfrac{-1}{4} +\frac{5}{2} =\dfrac{9}{4} \\g(x)=\dfrac{3x^2}{2}+\dfrac{x}{2}-5\\\\G(x)=\dfrac{x^3}{2}   +x^2-5x\\\\G(2)=4+1-10=-5\\\\G(-1)=\dfrac{-1}{2} +\dfrac{1}{4} +5=\dfrac{19}{4} \\\\\int\limits^2_{-1} {(f(x)-g(x))} \, dx =F(2)-G(2)-(F(-1)-G(-1))\\\\=11+\dfrac{5}{2} =\dfrac{27}{2}

For a singing contest in which 42,000 votes were cast the winner received 3/5 of votes. How many votes did the winner not receiv
DENIUS [597]
3/5 of 42000 is 25200 so the amount of people who did not vote is 16800 because the beginning amount of 42000 subtracted from 25200 gives you the final answer If that's confusing the answer is 16800 votes didn't pick the winner

Can someone explain this to me ?
Alex Ar [27]

Suppose you had f=6, g=2, h=3 and you were asked to find

f - g - h

You would do it by substituting the given values for the letters to get

6 - 2 - 3

And this can be simplified to

1

_____

The question at hand is basically the same. You are given values of f(x), g(x), h(x) and asked to find their signed sum.

f(x) - g(x) - h(x)

= (3x+5) - (4x²-2) - (x²-3x+1) . . . . substitute the given values

= 3x + 5 - 4x² + 2 - x² + 3x - 1 . . . use the distributive property to eliminate parentheses. A minus sign in front changes the sign of every term inside parentheses.

= x²(-4-1) +x(3+3) +(5+2-1)

= -5x² + 6x + 6 . . . . . . collect terms . . . . matches the first choice
