Answer:

  256,096 ft²

Step-by-step explanation:

<u>Pyramid Area</u>

Each of the four faces is a triangle with a base of 756 feet and a height of 612 feet. The area of that triangle is ...

  A = 1/2bh

  A = 1/2(756 ft)(612 ft) = 231,336 ft²

The total area of the four visible faces of the Great Pyramid is ...

  pyramid area = 4 × 231,336 ft² = 925,344 ft²

__

<u>WTC Area</u>

Each of the four rectangular side faces of the WTC tower has a base length of 208 ft and a height of 1368 ft. The area of it is ...

  A = LW = (208 ft)(1368 ft) = 284,544 ft²

The area of the square top of the tower has an area that is ...

  A = s² = (208 ft)² = 43,264 ft²

The total area of the four visible sides and the top is ...

  WTC tower area = 4 × 284,544 ft² +43,264 ft² = 1,181,440 ft²

__

The difference between the areas is ...

  WTC tower area - Great Pyramid area =

     1,181,440 ft² -925,344 ft² = 256,096 ft²

The difference in visible area is 256,096 ft².

True [87]

Answer:

<h2>10 units</h2>

Step-by-step explanation:

It's important to know that the centroid is always two-thirds of the median. Which means

AG=\frac{2}{3}FA\\ x+9=\frac{2}{3}(5x+x+9)\\ x+9=\frac{2}{3}(6x+9) \\x+9=4x+6\\9-6=4x-x\\3x=3\\x=1

Which means AG=x+9=1+9=10.

But, the centroid has always the same distance from each vertex, which means

AG=BG=10

Therefore, BG is 10 units long.

Answer: e. x≠2             f. x≥-1/2

Step-by-step explanation:

Domain is basically the x value of a function.

----------------------------------------------------------------

Question e.

g(x)=5/(2-x)

First, keep in mind, the denominator of a fraction can not be zero or else it will be undefined.

Since x is in the denominator: 2-x≠0

2-x≠0

<h2>    x≠2 Yes, this is the domain</h2>

----------------------------------------------------------------

Question f

h(x)=√(2x+1)

For a standard square root, the value inside can't b negative

So 2x+1≥0

        2x≥-1

<h2>           x≥-1/2 Yes, this is the domain</h2><h2 />

Hope this helps!! :)

Jack earns $50 for washing cars on the weekend. He makes an average of $4.25 in tips per hour. Write the function of Joe's earni
Elena-2011 [213]
A function for this would be m = 50 + 4.25t. The $50 is the one time thing. We must multiply the tips by 6. 4.25 * 6 = 25.50. 50 + 25.50 is 75.50. Joe would make $75.50 after 6 hours.
