Answer:

1652w-1652  is equivalent to \left(2w-2\right)\left(826\right)

In other words:

\left(2w-2\right)\left(826\right)=\:1652w-1652

Step-by-step explanation:

Considering the expression

\left(2w-2\right)\left(826\right)

solving

\left(2w-2\right)\left(826\right)

=\left(826\right)\left(2w-2\right)

\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b-c\right)=ab-ac

a=\left(826\right),\:b=2w,\:c=2

=\left(826\right)\cdot \:2w-\left(826\right)\cdot \:2

=826\cdot \:2w-826\cdot \:2

=1652w-1652

Therefore,

1652w-1652  is equivalent to \left(2w-2\right)\left(826\right)

In other words:

\left(2w-2\right)\left(826\right)=\:1652w-1652

What is the value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and de
Fudgin [204]

Answer:

The value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95

Step-by-step explanation:

Cost of building 20 years ago = 12000000

We are given that the cost depreciated at 9% per year

Formula : N(t)=N_0(1-r)^t

Where N(t)= Population after t years

N_0=Initial population=12000000

r= rate of depreciation=0.09

t = 20 years

Substitute the values in the formula:

N(t)=N_0(1-r)^t\\N(t)=12000000(1-0.09)^{20}

N(t)=1819738.95

Hence the value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95

Which relation represents a function? StartSet (0, 0), (2, 3), (2, 5), (6, 6) EndSet StartSet (3, 5), (8, 4), (10, 11), (10, 6)
postnew [5]

Answer:

<h2>Third set.</h2>

(-2, 2), (0, 2), (7, 2), (11, 2)

Step-by-step explanation:

A function is defined as a relation where each x-value (domain), has only one y-vale assigned (range). If one x-value has more than one image in the range, therefore, that's not a function. So, let's see which relation represents a function.

First: (0, 0), (2, 3), (2, 5), (6, 6).

As you can see, this set doesn't represent a function, because for x=2 there are two images assigned y=3 and y=5.

Second: (3, 5), (8, 4), (10, 11), (10, 6).

Similarly, this relation is not a function, because x=10 has to images, y=11 and y=6.

Third: (-2, 2), (0, 2), (7, 2), (11, 2)

As you can see, this is a function, because each pair has different value in the domain. Notice that there's the same image for each x-value, that still fulfil the definition of a function, because one element in the image can have multiple elements in the domain, what cannot happen is the opposite case.

Fourth: (13, 2), (13, 3), (13, 4), (13, 5).

This relation is not a function, because the same x-value has multiple images.

Therefore, the right answer is the third set.

I need help I never got taught how to do this
ludmilkaskok [199]

Answer:

736cm²

Step-by-step explanation:

The surface area of a regular pyramid is equal to:

area of the square base + 1/2ps

where p is the perimeter of the base and

s is the height of the slant line of the pyramid.

In your drawing s = 15cm and the base has four equal lengths of 16cm

So first find the area of the base.  Since this is a square, the area is just the

length x the width or 16cm x 16cm = 256cm²

(p) is the perimeter of the base.  Find this by adding all four side of the bottom square together which is 16cm + 16cm + 16cm + 16cm  or  4 x 16cm which is 64cm.

You already were given (s) which is the height of the slanted side from the base to the pointed top.  The drawing gives you this as 15cm.

So plugging all this into the formula, you get:

Surface Area = Area of Base + 1/2 p s

                      =  256 cm² + [1/2 ( 64cm )(15cm)]

                      =  256 cm²  +  {1/2 ( 960 cm²)]

                      =  256 cm²  +  480 cm²

                      =  736 cm²
