Maths help please!!!!!! PART B ONLY
andreyandreev [35.5K]

Answer:

19.37.

Step-by-step explanation:

Integrating the  function we get

x^4/4 - 5x^3/3 + x^2 + 8x

Area under the curve from x = -1 to x = 0

= (-1)^4/4 - 5(-1)^3/3 + (-1)^2 - 8

= 5.083

In a similar way we calculate area from 0 to 2

this = 10.667.

Total = 15.75.

Now we subtract 12.13 to get the area  from x = 2 to x =p.

= 15.75 - 12.13 = 3.62

So total shaded area = 15.75 + 3.62

= 19.37.

Which questions can be answered by finding the surface area? Check all that apply.
True [87]

Answer:

Step-by-step explanation:

Surface area is pretty synonymous with area.

How much paint is needed to paint the outside of a birdhouse?

Paint is measured in volume, so not surface area

How much wallpaper is needed to cover the walls of your room?

Since its just the walls its not total surface area, but surface area of the walls.

How much water will it take to fill a rectangular container?

water is measured in volume, especially when wanting to fill something.

How much topsoil can a gardener place in his wheelbarrow?

Wants to know how much topsoil is needed to FILL the wheelbarrow, filling is volume.  So not surface area.

How much fabric is needed to make a pillowcase for a pillow?

Not asking to fill the pillowcase, just how much is needed for the thin, one layer thick case.  So this is surface area.

What number must i add to complete the square x^2+8x=-3
Sonja [21]

Answer:

16

Step-by-step explanation:

(b/2)^2

(8/2)^2 = (4)^2 = 16

(x^2+8x+16) = -3+16

(x+4)^2 = 13

so on so forth, but basically you add 16 which completes the square
