wolverine [178]3 years ago
7 0

Answer:

5,2

Step-by-step explanation:

Here, we want to find the point that is a solution to the system of inequalities

From what we have, the points that lie in the dark brown patch represent the solution to the system

Hence the coordinates lying in these parts are the solution to the system

An example of such coordinates is the point (5,2)

Solve Tan^2x/2-2 cos x = 1 for 0 < or equal to theta < greater or equal to 1.
mixer [17]

Answer:

x = theta = 0°

Step-by-step explanation:

Given the trigonometry function

Tan²x/2-2 cos x = 1

Tan²x-4cosx = 2 ... 1

From trigonometry identity

Sec²x = tan²x+1

tan²x = sec²x-1 ... 2

Substituting 2 into 1, we have:

sec²x-1 -4cosx = 2

Note that secx = 1/cosx

1/cos²x - 1 - 4cosx = 2

Let cosx. = P

1/P² - 1 - 4P = 2

1-P²-4P³ = 2P²

4P³+2P²+P²-1 = 0

4P³+3P² = 1

P²(4P+3) = 1

P² = 1 and 4P+3 = 1

P = ±1 and P = -3/4

Since cosx = P

If P = 1

Cosx = 1

x = arccos1

x = 0°

If x = -1

cosx = -1

x = arccos(-1)

x = 180°

Since our angle must be between 0 and 1 therefore x = 0°

Her mean score for the first 7 holes is around 2 because 4+11=15 and 15 divided by 7 equals a little over 2

Find the measure of the indicated angle to the nearest degree.<br> 8<br> 22<br> ?
Blizzard [7]

Answer:

21 degrees

Step-by-step explanation:

To find this, we are going to use the appropriate trigonometric ratio

The right angle faces the length 22 which is the hypotenuse

The marked angle faces the length 8 which makes it the opposite

The trigonometric ratio that links the two is the sine

The sine is the ratio of the opposite to the hypotenuse

So, we have it that;

sine ? = 8/22

? = arc sine 8/22

? = 21 degrees
