Answer:
r < -12 and r > -6
Step-by-step explanation:
The distance of the ball from the foot of the tower is : 35.18m
The ball would be moved 57.2m away from the foot of the tower for the Angle of elevation to be halved.
<h3>What is angle of elevation?</h3>
Angle of elevation is the angle formed between the horizontal and the line of view from the vertical.
Analysis:
The height of the tower and the distance of the ball from the foot of the tower form a right angle triangle.
so we use trigonometry.
a) let distance of the ball from foot of tower be x.
so that, tan 52 = 45/x
x = 45/tan52
x = 45/1.279 = 35.18m
b) let the distance of the ball in the new position from the foot of the tower be y.
if the angle of elevation is halved, then new angle is 52/2 = 26°
tan 26 = 45/y
y = 45/tan26 = 45/0.487 = 92.4m
distance moved from old position to new position = 92.4 - 35.18 = 57.2m
In conclusion, the distance of the ball from the foot of the tower and the distance the ball should move to make its elevation 26° are 35.18m and 57.2m respectively.

Answer:
Total amount of fluid sold = 63 ounces
Step-by-step explanation:
Given:
Each bottle contain = 2.1 ounces
Total number bottle = 30
Find:
Total amount of fluid sold
Computation:
Total amount of fluid sold = Each bottle contain x Total number bottle
Total amount of fluid sold = 2.1 x 30
Total amount of fluid sold = 63 ounces
Answer:
See below.
Step-by-step explanation:
If the exponent is a/b then a is the power and b is the value of the radical.
Example: x^2/3 = ∛x². 2 is the power and 3 is the radical.
Answers:
1) 7^2/3 = ∛7²
5) √3 = 3^1/2
9) (∛27)⁴ = 27^4/3 = 3^4 = 81.
