Find the sum of the following geometric sequences. d) 3 terms a= 16 r=3/4​
kodGreya [7K]

Answer:

S₃ = 37

Step-by-step explanation:

given a₁ = 16 and r = \frac{3}{4} , then

a₂ = a₁ × \frac{3}{4} = 16 × \frac{3}{4} = 12

a₃ = a₂ × \frac{3}{4} = 12 × \frac{3}{4} = 9

then

S₃ = a₁ + a₂ + a₃ = 16 + 12 + 9 = 37

A weather balloon is launched from the ground at a spot 250 yards from a 65 foot royal palm tree . What is the minimal angle of
ValentinkaMS [17]

Answer:

Angle of elevation at which the balloon must take off in order to avoid hitting the tree is 5 degrees

Step-by-step explanation:

Given:

The height of the tree  = 65 foot

The distance between the tree and the spot from which the balloon is launched = 250 yards

To find:

The angle of elevation at which the balloon must take off in order to avoid hitting the tree = ?

Solution:

Converting the yards to feet

1 yards = 3 feet

250 yards = 3 x 250 = 750 yards

Refer the below figure, The angle x is the angle of elevation at which the the ball must be thrown so that it does not Hit the tree

tan(x) = \frac{opposite}{adjacent}

Substituting the values

tan(x) =  \frac{65}{750}

tan(x) = 0.086

x = tan^{-1}(0.086)}

x =  4.91^{\circ}

x \approx5^{\circ}
