Corey flying a kite with 105 meters of string. His string makes an angle of 42 degrees with the level ground. How high is the kite to the nearest meter?

Given:

Given that Corey is flying a kite with 105 meters of string.

The string makes an angle of 42° with the ground level.

We need to determine the height of the kite.

Height of the kite:

The height of the kite can be determined using the trigonometric ratio.

Thus, we have;

From the given data, the values are  , opp = h (height of the kite) and hyp = 105 meters.

Substituting the values, we get;

Multiplying both sides of the equation by 105, we get;

Rounding off to the nearest meter, we get;

Thus, the height of the kite is 70 meters.

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}
