From the point on the ground 500 ft from the base of a building, it is observed that the angle of elevation to the top of the bu
AveGali [126]

Answer:

  • building: 222.61 ft
  • flagpole: 32.15 ft

Step-by-step explanation:

The tangent function of an angle in a right triangle is the ratio of the opposite side to the adjacent side. Here, the adjacent side is 500 ft, so we have ...

  tan(24°) = (building height)/(500 ft)

  building height = (500 ft)tan(24°) ≈ 222.61 ft

__

Similarly, the height to the top of the flagpole is ...

  total height = (500 ft)tan(27°) ≈ 254.76 ft

The length of the flagpole is the difference of these heights:

  flagpole length = 254.76 ft -222.61 ft = 32.15 ft

The height of the building is 222.61 ft; the length of the flagpole is 32.15 ft.

Complete the expression that represents the table<br><br> Y=___x
bezimeni [28]

Answer:

The equation that represents the table is:

  • y=\frac{9}{2}x

Step-by-step explanation:

Taking two points from the table

  • (2, 9)
  • (4, 18)

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(2,\:9\right),\:\left(x_2,\:y_2\right)=\left(4,\:18\right)

m=\frac{18-9}{4-2}

m=\frac{9}{2}

As the slope-intercept form is

\:y=mx+b

Plugging (2, 9) to find the y-intercept 'b'

9=\frac{9}{2}\left(2\right)+b

\mathrm{Switch\:sides}

\frac{9}{2}\left(2\right)+b=9

\mathrm{Remove\:parentheses}:\quad \left(a\right)=a

\frac{9}{2}\cdot \:2+b=9

9+b=9

b=0

so the equation becomes

\:y=mx+b

  • m=\frac{9}{2}
  • b=0

y=\frac{9}{2}\left(x\right)+0

y=\frac{9}{2}x

Therefore, the equation that represents the table is:

  • y=\frac{9}{2}x

The graph of the equation is also attached below.
