Answer:

\frac{ \cos(80) }{ \sin(10) }  +  \frac{ \sin(20) }{ \cos(70) }  = 2 \\  \frac{ \cos(90 - 10) }{ \sin(10) }  +  \frac{ \sin(20) }{ \cos(9 0 - 20) }  = 2 \\  \frac{ \sin(10) }{ \sin(10) }  +  \frac{ \sin(20) }{ \sin(20) }  = 2 \\ 1 + 1 = 2 \\ 2 = 2 \\  \\  \frac{ \cot(40) }{ \tan(50) }  +  \frac{ \cos(65) }{ \sin(115) }  = 2 \\  \frac{ \cot(90 - 50) }{ \tan(50) }  +  \frac{ \cos(65) }{ \sin(90 + 65) }  = 2 \\  \frac{ \tan(50) }{ \tan(50) }  +  \frac{ \cos(65) }{ \cos(65) }  = 2 \\ 1 + 1 \\  = 2

What’s three points that satisfy the system of inequality’s of 4x+6y<24
Vlada [557]

Answer:

(0,0), (1,1), (2,2)

Step-by-step explanation:

When testing to find possible points in situations like this, I always start by testing with the origin point (0,0).

In this case:

4x+6y<24 ==> 0 + 0 < 24  TRUE, it satisfies the inequality.

We then try with (1,1):

4x+6y<24 ==> 4 + 6 < 24  TRUE, it satisfies the inequality.

And with (2,2):

4x+6y<24 ==> 8 + 12 < 24  TRUE, it satisfies the inequality.

Oliver has a bag that contains pineapple chews, lemon chews, and peach chews. He performs an experiment. Oliver randomly removes
Shtirlitz [24]

The probability that the next chew Oliver removes from the bag will be peach chew as a percent to the nearest whole number will be 13%.

<h3>What is probability?</h3>

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

Oliver has a bag that contains pineapple chews, lemon chews, and peach chews.

He performs an experiment.

Oliver randomly removes a chew from the bag, records the result, and returns the chew to the bag.

Oliver performs the experiment 23 times.

The results are shown below:

A pineapple chew was selected 17 times.

A lemon chew was selected 4 times.

A peach chew was selected 2 times.

Then the probability that the next chew Oliver removes from the bag will be peach chew as a percent to the nearest whole number will be

Total event = 24 times

Favorable event = 3 times

Then we have

P = 3 / 24 x 100

P = 0.125 x 100

P = 12.5%

P ≅ 13%

More about the probability link is given below.
