Answer:
17 degrees
Step-by-step explanation:
So to find the answer you need to subtract. If the temp went down 22.1 degrees and it is -5.1 degrees you will subtract 22.1 - 5.1. This equals 17 degrees. You know the answer is correct because you can check your answer by adding: 5.1 + 17 = 22.1. We are disregarding the negative sign.
Answer:
D) x=-1, x=-9
Step-by-step explanation:
x=-1, x=-9
Answer:
(-4,5)
Step-by-step explanation:
-8-(-6)=2
3-1=2
-8+2=-6
1+2=3
-6+2=-4
3+2=5
(-4,5)
A = B
3x+20 = 5x-12
Subtract 3x on both sides
20 = 2x-12
Add 12 on both sides
32 = 2x
Divide by 2 on both sides
16 = x
Option c
First, you need to remember how to obtain the answer.
1) (velocity)*(cosine of the angle)2)(velocity)*(sine of the angle)
Since the plane is traveling 45 degrees below the horizon the angle that we will be using is 180+45=225.
Therefore we will have,
150* cos(225) = -81.31
150*sin(225) = -81.31
*In the unit circle, the coordinates of 225 are -squareroot(2) divided by 2 for both sin and cos, which explains why we have the same answer for both sin and cos.
The answer being negative makes sense since the speed is decreasing due to the fact that the plane is traveling below horizontal.
