Please help me understand this!Problem:The net of a rectangular prism and it's dimensions are shown in the diagram.Question:What

Sphinxa [80]

Surface Area

The image shows the shape of a rectangular prism

The surface area of the shape is the sum of all the individual rectangles

There are 6 small rectangles. We'll find their area and add them up to find the total surface area.

The area of a rectangle of dimension L and W is:

A=L.W

First rectangle: 3 in x 7.5 in

A1 = 3 * 7.5 = 22.5 square inch

Second rectangle: 11.5 in x 3 in

A2 = 3 * 11.5 = 34.5 square inch

Note this rectangle is repeated twice

The third rectangle has the same area of the first rectangle:

A3 = 3 * 7.5 = 22.5 square inch

The fourth rectangle has dimensions of 7.5 x 11.5

A4 = 7.5 * 11.5 = 86.25 square inch

This rectangle is also repeated twice

The total area is :

A = A1 + A2 + A2 + A3 + A4 + A4

A = 22.5 + 34.5 + 34.5 + 22.5 + 86.25 + 86.25

A = 286.5 square inch

Answer: D.

I only really need the domain and range, intervals, and end behavior. My Precalculus class never covered piecewise functions so

Serjik [45]

(a)

Domain:

we know that domain is all possible values of x for which any function ios defined

Here, curve is defined for all values of x

so, domain is

$(-\infty,\infty)$

Range:

Range is all possible values of y for which x is defined

minimum value of y is -4

maximium value of y is +inf

so, range is

$[-4,\infty)$

(b)

x-intercept:

It is the value of x where f(x)=0

so, the point where curve intersects on x-axis

and we get

$2x^2-4=0$

$x=\sqrt{2}$

and

$x=-5$

(c)

Increasing interval:

where curve is moving upward

we can see that

$(0,\infty)$

Decreasing interval:

where curve is moving downward

we get

$(-\infty,-1)U(-1,0)$

Constant:

constant means horizontal line

there is no horizontal line here

so, it does not exist

(D)

End behavior:

when x-->+inf

y is moving upward

so, y---->+inf

when x-->-inf

y is moving upward

so, y---->+inf

(E)

we can see that curve jupms at x=-1

so, there is discontinuity at x=-1

and this is jump type of discontinuity

(F)

For odd:

f(-x)=-f(x)

For even:

f(-x)=f(x)

we can see that none of them holds true

so, this is neither

Surface area of cuboid 20 mm 8mm 11mm

SpyIntel [72]

Answer:

936mm^2

Step-by-step explanation:

Surface area of cuboid 20 mm 8mm 11mm

Surface area of the cuboid=2(20×8+8×11+11×20)

=2(160+88+×220)

=2(468)

=936mm^2

So the answer is936mm^2
