Answer:
2rcosθ+3rsinθ=6
Step-by-step explanation:
x=rcosθ
y=rsinθ
2rcosθ+3rsinθ=6
The stem and leaf plot will look like:
6 | 1 5 8 - 3 scores
7 | 1 7 7 9 - 4 scores
8 | 2 3 4 5 7 9 - 6 scores
9 | 0 1 4 7 9 - 1 score
To total up the number of students who scored less than 90, we have 3 under 60-69, 4 under 70-79, and 6 under 80-89, so this is 3 + 4 + 6. This is the third choice.
Answer:
The graph crosses the x-axis at x = 0 and touches the x-axis at x = 3.
Step-by-step explanation:
When you graph this equation, you should see the zeros it passes and touches.
Answer:
In my guess I'll go for Slope = 
y-intercept = 10
83.3
Just add up all the numbers and divide by 6, as there are six numbers in this set of numbers
