A building in the shape of a square pyramid is being built in Las Vegas. The height of the building will be 309 feet, and a size
finlep [7]

Answer: 51.5 cubic feet.

Step-by-step explanation:

Since,  The height of the building will be 309 feet, and a size of the base measures 250 feet.

And, we know that the volume of the square pyramid = (size of the base)^2\times \frac{height}{3}

Here, size of the base of the square pyramid = 250 feet.

And, height = 309 feet.

Therefore, the volume of the given square pyramid,

V=(250)^2\times\frac{309}{3}

⇒ V=62500 \times\frac{309}{3}

⇒ V= \frac{19312500}{3} = 6437500 cubic feet.

Again according to the question,

The scale model that is displayed at a convention is one fiftieth the size of the actual building.

Therefore, Volume of the scale model = the volume of the given square pyramid/125000

= 6437500/125000= 51.5 cubic feet.

Thus, the volume of the scale model is  51.5 cubic feet.

-4x^2-12x+1 find the standard form
34kurt
I'd stay this expression is already in standard form, although you could rewrite it as   -(<span>-4x^2-12x+1).

You could rewrite   </span><span>-4x^2-12x+1    by completing the square:

-4(x^2 + 3x                    )                         +1  becomes

-4(x^2 + 3x + [3/2]^2     )       - [3/2]^2       + 1, or

-4(x + 3/2)^2           + 1 - 9/4,    or

-4(x+3)^2      -5/4    (final form)     The graph would be that of a parabola with vertex at (-3, -5/4).  This parabola would open down and would be vertically stretched by a factor of 4.</span>

Use double to help you add 8+7
Aloiza [94]
You can subtract 8 -1=7 and then add 7+7=14 and then do 14+1=15 because we subtracted 1 from 8.

A line has a slope of one and a y-intercept of nine. What is the equation of a slope intercept form?
Masteriza [31]

Answer:

y=x+9 (or y=1x+9, same thing)

Step-by-step explanation:

The equation for Slope-Intercept is y=mx+b. M is the slope, an B is the Y-intercept. Since 1 is the slope, m=1, and B=9 because 9 is the Y-intercept.
