Y=-3
subtitute to y^2 + 6y +8
= (-3)^2 + 6(-3) + 8
= 9-18+8
= -1

Answer:

-1

Step-by-step explanation:

Substitute in the known variables:

$y^2 + 6y + 8\\(-3)^2 + 6(-3) + 8\\$

$-3 * -3 = 9\\(-3)^2 = 9$

$9 + 6(-3) + 8\\9 + (-18) + 8\\9 - 18 + 8$

= -1

Hope this helps!

Here you'll want to add 5/8 with 5/8. Since they have the same denominator already then 5/8+5/8 = 10/8. Simplifying that down to 5/4 then changing to a mixed number is 1 1/4 inches.

It sounds like R is the region (in polar coordinates)

R = {(r, θ) : 2 ≤ r ≤ 3 and 0 ≤ θ ≤ π/2}

Then the integral is

$\displaystyle \iint_R\frac{\mathrm dx\,\mathrm dy}{\sqrt{x^2+y^2}} = \int_0^{\pi/2}\int_2^3 \frac{r\,\mathrm dr\,\mathrm d\theta}{\sqrt{r^2}} \\\\ = \int_0^{\pi/2}\int_2^3 \mathrm dr\,\mathrm d\theta \\\\ = \frac\pi2\int_2^3 \mathrm dr \\\\ = \frac\pi2r\bigg|_2^3 = \frac\pi2 (3-2) = \boxed{\frac\pi2}$
