A ball is thrown from a height of 49 meters with an initial downward velocity of 2 m/s. The ball's height (in meters) after t se
horsena [70]

The height of the ball at ground level would be 0 feet.

Set h to 0 and solve for t:

Rewrite the equation as  

-5t^2 -2t +49 = 0

Factor -1 out of the equation to get:

5t^2 + 2t -49 = 0

Use the quadratic formula:

-b +/- sqrt(b^2 -4(ac) / 2a

Where a = 5, b = 2 and c = -49

The quadratic formula becomes:

-2 +/-sqrt(2^2 – 4(5*-49) / (2*5)

Simplify to get :

T = -2 +/-sqrt246 / 10

T = 2.936 and – 3.336

Since the time has to be a positive value t = 2.936 seconds.

Rounded to the nearest hundredth = 2.94 seconds.

You are standing 45 meters from the base of the Empire State Building. You estimate that the angle of elevation to the top of th
romanna [79]

Answer:

[45tan(82°)+123] meters

A is correct

Step-by-step explanation:

You are standing 45 meters from the base of the Empire State Building.

You estimate that the angle of elevation to the top of the 86th floor(the observatory) is 82°.

If the total height of the building is another 123 meters above the 86th floor.

OB = 45 m , ∠O= 82°

In Δ OBA, ∠B = 90°

\tan82^\circ=\dfrac{AB}{OB}

\tan82^\circ=\dfrac{AB}{45}

AB=45\tan82^\circ

Top of the building, T at 123 m from A

Total height of building = BA + AT

                                =45\tan82^\circ+123\text{ meters}

Hence, The height of building from ground is [45tan82°+123] meters

Maksim231197 [3]

Answer:

95 is the answer

Step-by-step explanation:

180 - 144 = 36

180 - 121 = 59

180 - 59 - 36 = 85

180 - 85 = 95
