A drone is flying over a
baseball field, directly between
first and second base. The angle
of elevation from first and second
base to the drone is 77° 9' and
65° 45' 18", respectively.
If the bases are 90 feet apart,
find the height of the drone.
Answers
The height of the drone would be about 132.92 feet.
What is a tangent ratio in trigonometry?
The tangent ratio is the ratio of the opposite side to the adjacent side of a right triangle. Same to the sine and cosine ratios, tangent ratios can be used to calculate the angles and sides of right-angle triangles.
Given that the angle of elevation from the first and second base to the drone is 77° 9' and 65° 45' 18", respectively.
[tex]77^o9'=77\frac{9}{60}=77.15^o[/tex]
[tex]65^o 45' 18"=65+\frac{45}{60}+\frac{18}{3600}\\\\65^o 45' 18"=65.755^o[/tex]
tan 77°9 = h/AD and tan 65.75°=h/DB
AD + DB = 90
h/tan 77°9 + h/65.75° = 90
Solving this we get
h ≈ 132.92 feet.
Hence, the height of the drone would be about 132.92 feet.

What is trigonometric ratios?Trigonometric functions are real functions in mathematics that connect an angle of a right-angled triangle to ratios of two side lengths. They are widely utilized in all geosciences, including navigation, solid mechanics, celestial mechanics, geodesy, and many more. The values of all trigonometric functions depending on the ratio of sides of a right-angled triangle are defined as trigonometric ratios. The trigonometric ratios of any acute angle are the ratios of the sides of a right-angled triangle with respect to that acute angle.
Here,
cos 30°=b/15
b=15*cos 30°

a) What is the maximum height of the ball? __ feet
b) How many seconds does it take until the ball hits the ground? __ seconds
Answers
Answer:
the answer is 306.25 feet and b is 8 sec
Step-by-step explanation:
Explanation
The height of the ball as a function of the time is given by the following formula:
A. Maximum height of the ball
To find the value of the maximum height, we maximum the function h(t) computing its first derivative and equalling the result to zero:
Solving the last equation for t, we get time t when the height is maximum:
So the maximum height is given by the value of h(t) when t = 2.5:
The maximum height is 196ft.
B. Time until the ball hits the ground
The ball will hit the ground when h(t) = 0. So we must find the value of t such that:
Solving this equation is equivalent to finding the roots of a second-order polynomial:
Where:
• a = -16,
,
• b = 80,

• c = 96.
The roots of this polynomial are given by the following formula:

We know that, sum of the exterior angles of a quadrilateral is added up to 360°.
Accordingly,

Combine like terms.
115 + 35z = 360

35z = 245
Divide both sides by 35.

Water is being from a pool. The volume of water in the pool t minutes after begin draining is given by the function V(t)=4522(0.94)^t. Which of the following is the closest to the percent volume that has drained out of the pool after 10 minutes
Answers
The closest percentage volume that has drained out is 46%
How to determine the percentage volume?From the question, we have the following parameters that can be used in our computation:
V(t) = 4522(0.94)^t
The initial volume is calculated when t = 0
So, we have
V(0) = 4522(0.94)^0
Evaluate
V(0) = 4522
The new volume is calculated when t = 10
So, we have
V(10) = 4522(0.94)^10
Evaluate
V(10) = 2435.62
The percentage is then calculated as
Percentage = (V(10) - V(0))/(V(0))
So, we have
Percentage = (2435.62 - 4522)/4522
Evaluate
Percentage = -46%
Hence, the percentage is 46%
