What is the value of cosine theta in the diagram below?
A unit circle is shown. A radius with length of 1 forms angle theta in the first quadrant. The radius goes to point (0.6, 0.8) on the unit circle.
Three-fifths
Three-fourths
Four-fifths
Four-thirds
Answer:
A: Three-fifths
Step-by-step explanation:
I have attached an image to depict this question.
We can see that the point at which the radius goes on the unit circle is a coordinate (x, y)
We are told this coordinate is (0.6, 0.8)
Now, in these type of unit circle diagrams;
x = cos θ and y = sin θ.
Thus;
cos θ = 0.6
cos θ = 6/10
Simplifying gives;
cos θ = 3/5

A. 3/5

Answer:
Y is the midpoint of XZ, so XY = YZ
20x - 30 = 12x + 1020x - 12x = 10 + 308x = 40x = 5Find XZ:
XZ = 2(XY) = 2(20*5 - 30) = 140The answer is:
x = 5 and XZ = 140------------------------
B is the midpoint of AC, so AB = BC
4x + 3 = 2x + 154x - 2x = 15 - 32x = 12x = 6Find AC:

x = 6, AC = 54help get brainliest asap
Answer: x =67
Step-by-step explanation:
The equation to solve this is (x - 22) + 135 = 180
1) To solve for x, you must remove the parenthesis
x - 22 + 135 = 180
2) Simplify the equation...
x - 113 = 180
3) Simplify the equation
180-113 = x
3) Subtract to solve
180 - 113 = x
x = 67
Answer :
As shown in the figure the angles x - 22 and 135 lie on a straight line . So we may solve it using linear pair property that states that the sum of angles lying on a straight line is 180° .
( x - 22 ) + 135 = 180°Remove the brackets x - 22 + 135 = 180Subtract 22 from 135 and as 135 is is greater than 22 the sign will be positivex + 113 = 180Subtract 113 from both the sides x = 180 - 113x = 67°Thus the correct answer is option d that is x = 67

Do you know what the FACTORS are of this generic rectangle
Answer: The two factors are x+7 and x+2
The polynomial factors to (x+7)(x+2)
=========================================================
Explanation:
In the upper left corner we have x^2. We get this by multiplying x with x
So,
x*x = x^2
This means you'll have x to the left of x^2, and another copy of x above the x^2. These new terms are outside the box.
Now ask yourself, what goes in the blank x times ___ = 7x. The answer must be "7" since x times 7 = 7x. So we'll write 7 above the 7x, outside the box. Up top, the x and 7 help form the factor (x+7)
Along the left side, the other factor is (x+2) for similar reasoning. Notice how we effectively have x times ___ = 2x and '2' must go in the blank. So a '2' must go to the left of the 2x.
Putting everything together, the two factors are (x+7) and (x+2).
Therefore, x^2+7x+2x+14 fully factors to (x+7)(x+2)
This is the same as saying x^2+9x+14 factors to (x+7)(x+2)

does the point (4,-2) lie on the circle with a center at (4,0) and a radius of 2?
Answer:
Yes
Step-by-step explanation:
It lies on the circle because the radius is 2 and the point goes down two units just like the radius
Answer:
yes
Step-by-step explanation:
the radius extends out 2 points throughout the entire circle therefore -2 will be reached as it is 2 units below the center of (4, 0)
