What's 5 5/6 as a improper fraction

A mobile base station (BS) in an urban environment has a power measurement of 8µW at 225m. Assuming the propagation follows an i

nata0808 [166]

Answer:

The reasonable value = 2.96 × 10^(-1) µW

Step-by-step explanation:

* Lets explain how to solve the problem

- A mobile base station in an urban environment has a power

measurement of 8 µW at 225 m

- The propagation follows an inverse cube power law

- We need to find the reasonable value to assume at a distance

678 m from the base station

∵ The propagation follows an inverse cube power law

- <em>The power would have been decreased by a factor 1/n³ </em>

<em> times the power as a distance increasing</em>

∵ n = the ratio between the distances

∵ The distance are 675 m and 225

∴ n = 675/225 = 3

∴ 1/n³ = 1/3³ = 1/27

- The reasonable value is the product of the power measurement of

8 µW and 1/27

∴ The reasonable value = 8 × 1/27 = 8/27 µW = 0.296296

∴ The reasonable value = 2.96 × 10^(-1) µW

A ball is kicked from ground level with a velocity of 20 m/s at 30 degrees above the horizontal. Determine the horizontal displa

olga55 [171]

Answer:the horizontal displacement is 34.64 meters

The maximum height is 15 meters

Step-by-step explanation:

As the ball moves from the ground at 30 degrees, it travels through a parabolic path. It can therefore be likened to a projectile. The horizontal displacement to where it lands is the range. The formula for determining range,R is

R = U^2Sin2#)/g

Where

U represents the initial velocity of the ball

g is acceleration due to gravity

# represents the angle above the horizontal.

From the information given

# = 30 degrees

U = 20 m/s

g = 10m/s^2

R = 20^2Sin2×30)/10 = (400Sin60)/20 = (400×0.8660)/10

= 34.64 meters

To determine the maximum height of the ball, H,

H = (U^2Sin^2#)/2g

H = (20^2 × Sin^2 30)/2×10

H = (400 × 0.866^2)/20 = 15 meters

WILL GIBE BRAINLIEST ASAP

Romashka [77]

Answer:

A and D have whole grid squares that are the same size and aren't over lapping

C has overlapping grid squares making it hard to count

B can't be used to find area because some of the grid squares are different sizes

You still could use B because four of the smaller squares seems to be equivalent to one of the larger squares

Write the expression as either the sine, cosine, or tangent of a single angle.

olya-2409 [2.1K]

There exists a trigonometric identity which states that,
sin (A - B) = sin A cos B - cos A sin B
This is very similar to the given expression with A equal to 57° and B equal to 13°. The simplified form of the angle is,
sin (57° - 13°) = sin 44°
