what is the ordered pair for 90 degrees on a unit circle

Answers

Answer 1
Sin 90°=1
Step-by-step explanation:
A unit circle is a circle with a radius of 1 .Because the radius is 1, it is possible to directly measure the sine, cosine and tangent.
using the unit circle where 90° is the limit as the hypotenuse approaches the vertical y-axis which is positive.
Sine=opposite/hypotenuse
Sin=O/H
Applying the limits
Sine 90°=1/1= 1
cos 90° =0/1 =0
or
When the angle formed at the origin of the unit circle in the 1st quadrant is 0°, cos 0°=1 sin0°=0 and tan 0°=0
When we increase the angle until it is 90°, cos 90°=0, sin 90°=1 and tan 90°=undefined

6) Find the value of x

Answers

Answer and Step-by-step explanation:

We are given a linear pair. The angles of a linear pair add up to 180.

To find x, add the two angles together and equal it to 180, then solve for x.

126 + x + 23 = 180

Simplify.

149 + x = 180

Subtract both sides of the equation by 149.

x = 31

x = 31 is the answer.

Answers

Answer: (below)

Step-by-step explanation:

The functions shown are exponential functions, which have the form f(x) = a*(b)^x. "a" represents the intial value, while "b" represents the growth factor.

To determine whether a function is growing or decaying, you look at the growth factor. If the growth factor is greater than 1, the function is growing, since each value is getting larger and larger. Meanwhile, if the growth factor is between 0 and 1, the function is decaying, since each value is getting smaller and smaller.

Now, back to this question, let's look at our functions. In the function on the left, the growth factor is 0.87, which is between 0 and 1, so this function is decaying. For the function on the right, the growth factor is 1.25, which is greater than 1, so this function is decaying. Next, let's look at our graphs. In the left graph, the function is growing, so it matches with the function on the right. Meanwhile, in the right graph, the function is decaying, so it matches with the function on the left.

Answers

Answer:

b=4

Step-by-step explanation:

4 Also can someone tell me how to do this? step by step?

b = 4 is not a solution to the inequality.

What they’re saying is substitute the number 4 into the inequality wherever the letter b appears.

So they are asking if “3 is greater than or equal to 4” is true or not true.

If it was true, then b = 4 is a solution to the inequality. Since it is false, it is not a solution to the inequality. Does that make sense?

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures created by the intersecting lines? Explain.

Answers

Adjacent angles create linear pairs so they add to 180. If we know the measure of one angle, we can find the other by subtracting from 180.

Vertical lines create congruent angles. If we know the measure of one angle, we know the measure of the angle opposite of it (they only share a vertex, no sides)

Answer:

If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

Jesse has reached 16% of his weekly reading time goal so far this week. If he has read for a total of
32 minutes this week, what is his weekly reading time goal in minutes?

Answers

x = time goal

16% = .16

.16 x = 32

x = 32/.16 = ___________ minutes

Jesse' weekly reading time is an illustration of ratio and proportion.

Jesse' weekly reading time is 200 minutes

Represent the reading time with x.

16% of his weekly reading time is given as 32 minutes

This is represented using the following equation

[tex]16 \% \times x = 32[/tex]

Express 16% as decimal

[tex]0.16\times x = 32[/tex]

Divide both sides by 0.16

[tex]x = 32/0.16[/tex]

[tex]x = 200[/tex]

Hence, Jesse' weekly reading time is 200 minutes
