-52
Step-by-step explanation:
8.4-2.22+12.4-4.22=
=32-44+48-88=
=-132+80=
=-52
The answer D is correct
Because the question ask about the value of the function at x =-2 you move 2 units to the left
You move to the left because its a negative
After you move to the left you go up unitl you get to where the line hits
Which is at (-2, 3)
So as you can see y would equal 3
Answer:
14
Step-by-step explanation:
The law of cosines is a² = b²+c²-2bc(cos A).
We will use s in place of a, since it is the unknown side. This makes b and c 8 and 9.
Angle A will be the angle opposite side a, or in this case side s. This makes it 111.
This gives us
s² = 8²+9²-2(8)(9)(cos 111)
s² = 64+81-2(8)(9)(cos 111)
s² = 145-144(cos 111)
s² = 196.605
Take the square root of each side:
√(s²) = √(196.605)
s = 14.02 ≈ 14
