Cos(θ) = -20/√((-20)^2 +(-21)^2)
.. = -20/-√841 . . . . . . . . . . . . . . . . . θ is a 4th-quadrant angle, so cos(θ) > 0
.. = 20/29
The value of the cosine is 20/29.
Answer:
A)
Step-by-step explanation:
Given expression:
To factor the given expression completely.
Solution:
In order to factor the expression, we will factor in pairs.
We will factor the G.C.F of the terms in the pairs.
G.C.F. of and can be given as:
Thus, G.C.F. =
G.C.F. of and can be given as:
Thus, G.C.F. =
The expression after factoring the G.C.F. pairs is given as:
Taking G.C.F. of the whole expression as is a common term.
The expression is completely factored.
Step-by-step explanation:
The broken wing weighed 10 pounds and 14 ounces. There are 16 ounces in a pound. I hope this helps!
<span>y=3x-12
2x-3y=-13
substitute </span>y=3x-12 into <span>2x-3y=-13
</span><span>2x-3y=-13
</span>2x-3(3x-12)=-13
2x - 9x + 36 = -13
-7x = -49
x = 7
y=3x-12 = y=3(7) -12 = 21 - 12 = 9
answer
solution
x = 7 and y = 9
