A kite with a string 80 feet long makes an angle of elevation of 40° with the ground, assuming the string is straight, how high
defon
The diagram of the kite is shown below

To find the perpendicular height of the kite from the ground, we use the trigonometry ratio for sin(x).

The reason for using the sine ratio is because we have the hypotenuse, 80 feet, and the angle, 40° and we are looking for the length of the side opposite the angle.

sin(x)= \frac{opp}{hyp}
sin(40)= \frac{x}{80}
80sin(40)=x
x=51.42 rounded to two decimal place

Perpendicular height of the kite from the ground is 51.42 feet

Is the sequence arithmetic? (Yes or no) If yes, please also give its common difference. 14) -2.8, -2.2, -1.6, -1.0
Firdavs [7]

Answer:

Yes

The common difference is .6

Step-by-step explanation:

Take the second term and subtract the first term

-2.2 - (-2.8)

-2.2+ 2.8 = .6

Take the third term and subtract the second

-1.6 - (-2.2)

1.6 +2.2

The common difference is .6

Select all of the quadrants that the parabola whose equation is x = y² + 1 occupies.
diamong [38]
Hello, and thank you for posting your question here on brainly.

When you solve the equation x = y^2 + 1, you get this line.

The line graphed takes both quadrants I & IV, or 1 & 4.

Hope this helps! ☺♥
