Perpendicular Lines meet at a 90° angle.
Answer:
simple interest: I = P × r × t
I = 4500 × 9.5% × 6 = 2565
Answer:
The average score for fourth-graders who study the subject about 235 minutes per week is 224.76.
Step-by-step explanation:
Let x be the number of hours fourth-graders study the subject per week and y be the average score on the test. It is given that there is an approximate linear relationship between x and y.
It is given that the average score on a national assessment test for a subject was 194 points for fourth-graders who studied the subject about 45 minutes per week. It means the line passes through (45, 194).
The average score was 211 points for fourth-graders who studied the subject about 150 minutes per week. It means the line passes through (150, 211).
If a line passes through two points then the equation of line is
The equation of required line is
Using distributive property,
Add 194 on both sides.
Substitute x=235 in the above equation.
Therefore the average score for fourth-graders who study the subject about 235 minutes per week is 224.76.
The turning point is just the minimum/maximum so the coordinates are (-3,1) which you find from the expression of (x+3)³ + 1
