What is the average value of y=cosx/x^2+x+2 on the closed interval "[-1, 3]"?

soldi70 [24.7K]

We have
<span>y=cos x/(x</span>²+x+2) <span>on the closed interval [-1, 3]
</span><span>
we know that
</span>The average value of f(x) on the interval [a, b] is given by:
<span>F(avg) = 1/(b - a) ∫ f(x) dx (from x=a to b).
(b-a)=(3+1)------> 4
</span>= 1/4 ∫ cos(x)/(x² + x + 2) dx (from x=-1 to 3).

Note that [cos(x)/(x² + x + 2)] does not have an elementary anti-derivative.
By approximating techniques:
1/4 ∫ cos(x)/(x^2 + x + 2) dx (from x=-1 to 3) ≈ 0.182951

the answer is
<span>the average value of y = cos(x)/(x</span>²<span> + x + 2) on [-1, 3] is approximately 0.182951</span>

Solve for x.<br>12:15=x:5

Feliz [49]

Set up the ratios as proportional fractions:

$\frac{12}{15} = \frac{x}{5}$

We can simplify the first fraction to make the problem easier. Both the numerator and denominator of the first fraction can be divided by 3:

$\frac{12}{15} \div \frac{3}{3} = \frac{4}{5}$
$\frac{4}{5} = \frac{x}{5}$

Both fractions now have the same denominator. Since both fractions have to equal each other, the numerators will also be the same. Therefore, x = 4.
