Use formula p=m/v
P is density
M is mass
V volume
So you have the volume already now 8x5x4= 160 which is the volume
P= 1800/160 after you divide you get 11.25
The density is 11.25

(4x^(4))^(2) without exponents
vlabodo [156]

Answer:

256x * 16

Step-by-step explanation:

(4x * 4x * 4) * (4x * 4x * 4 )

(16x * 4 ) * ( 16x *4)

16x * 16x = 256x

4 * 4 = 16

256x * 16

hope this helped a little

* = multiply

Space Shuttle Marion is observing the launch of a space
Vera_Pavlovna [14]

Using the slope concept, it is found that the shuttle traveled 3.2 miles while Marion was watching.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.

Initially, the angle of elevation is of 16º, with an elevation of 1 mi, hence:

\tan{16^\circ} = \frac{1}{x_1}

x_1 = \frac{1}{\tan{16^\circ}}

x_1 = 3.5

Then, at the end, the angle will be of 74º, with the elevation remaining constant, hence:

\tan{74^\circ} = \frac{1}{x_2}

x_2 = \frac{1}{\tan{74^\circ}}

x_2 = 0.3

The distance is:

d = x_1 - x_2 = 3.5 - 0.3 = 3.2

The shuttle traveled 3.2 miles while Marion was watching.
