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.
The answer is B
Which is SAA
<h3>
Answer: Line B better fits the data</h3>
The smaller sum of the squared residuals, or sum of the squared error, means there is less error when it comes to the line being from all the points. The regression line is closer to the points compared to line A.
Answer:
1. =2
2. times 2
3. b.
Step-by-step explanation:
Um I assume you're wanting the circumferences of the fences so we have 3 that are all the same size and one that is 3 times as large as any of the others
so here's our equations
3x+y=113.04
y=3x
use substitution
3x+3x=113.04
6x= 113.04
now the question says use 3.14 so I'm thinking you want the answer in terms of pi so first divide 113.04 by 3.14
6x=36pi
x=6pi now substitute that back in for x in one of your equations
y=(3)(6pi)
y=18pi
so the tomatoes carrots and cabbage will all have a circumference of 6pi and the strawberries 18pi
