Answer:

Bus B must be A) y = 40x

Step-by-step explanation:

We can tell this because it is growing at a slower rate than Bus A. As a result, we know the slope is less than 55. The only option that is less than 55 is A) 40x.

Ships A and B are 1,425 feet apart and detect a submarine below them. The angle of depression from ship A to the submarine is 59

andreyandreev [35.5K]

Answer: The distance from ship B to the submarine is 1270.68 feet and the distance from ship A to the submarine is 1084.18 feet.

Step-by-step explanation:

Since we have given that

Distance between Ships A and B = 1425 feet

Angle of depression from ship A to the submarine =59°

Angle of depression from ship B to the submarine = 47°

As shown in the figure below:

Remaining angle will be

$180\textdegree-(47\textdegree+59\textdegree)\\\\=180\textdegree-106\textdegree\\\\=74\textdegree$

So, we will use "Sine formula ":

$\frac{\sin 74\textdegree}{1425}=\frac{\sin 59\textdegree}{B}\\\\B=\frac{1425\times \sin 59\textdegree}{\sin 74\textdegree}\\\\B=1270.68\ feet$

Similarly,

$\frac{\sin 74\textdegree}{1425}=\frac{\sin 47\textdegree}{A}\\\\A=\frac{1425\times \sin 47\textdegree}{\sin 74\textdegree}\\\\A=1084.18\ feet$

Hence, the distance from ship B to the submarine is 1270.68 feet and the distance from ship A to the submarine is 1084.18 feet.

A rectangular prism has a length of 8 in., a width of 4 in., and a height of 214 in.

Ivan

For this case we have that by definition, the volume of a rectangular prism is given by:

$V = A_ {b} * h$

Where:

$A_ {b}:$ It is the area of the base

h: It is the height

So:

$A_ {b} = 8 * 4 = 32 \ in ^ 2\\h = 214 \ in$

The volume of the prism is:

$V = 32 * 214 = 6848 \ in ^ 3$

Now, the volume of the cubes is:

$V = (14) ^ 3 = 2744 \ in ^ 3$

Thus, we divide and find the number of cubes to fill the prism:

$n = \frac {6848 \ in ^ 3} {2744 \ in ^ 3}\\n = 2.5$

ANswer:

n = 2.5
