Slope integrals for calculus, having trouble need all the help I can get

Harlamova29_29 [7]

(1) The integral is straightforward; x ranges between two constants, and y ranges between two functions of x that don't intersect.

$\displaystyle\int_{-2}^1\int_{-x}^{x^2+2}\mathrm dy\,\mathrm dx$

(2) First find where the two curves intersect:

y ² - 4 = -3y

y ² + 3y - 4 = 0

(y + 4) (y - 1) = 0

y = -4, y = 1 → x = 12, x = -3

That is, they intersect at the points (-3, 1) and (12, -4). Since x ranges between two explicit functions of y, you can capture the area with one integral if you integrate with respect to x first:

$\displaystyle\int_{-4}^1\int_{y^2-4}^{-3y}\mathrm dx\,\mathrm dy$

(3) No special tricks here, x is again bounded between two constants and y between two explicit functions of x.

$\displaystyle\int_1^5\int_0^{\frac1{x^2}}\mathrm dy\,\mathrm dx$

Question 10 Multiple Choice Worth 2 points)

KatRina [158]

Answer: The specific heat of this compound is

a) It is higher than the specific heat of water.

Explanation:

Specific heat is the amount of heat needed by a substance of one gram to raise it's temperature by 1°C.

This specific heat is impacted by the strength of hydrogen bonding in any substance.

Hydrogen has the highest specific heat.

Value of specific heat is directly proportional to strength of bonding in a substance.

If the bonding is strong, it will need more energy to raise its temperature. Hence, specific heat will be more for that substance.
