Answer:
1. Quadratic function
2. y-intercept = 0
3. x-intercepts = 0, 6
4. greatest value of y = 9 when x = 3
5. y > 0
Step-by-step explanation:
2. The line crosses the y-axis at (0,0)
3. The line crosses the x-axis at (0,0) & (6,0)
4. The highest point is at 9 which is above 3; (3, 9)
5. The y value is greater than 0
I hope this helps!
<u>Answer</u> : The demonstration is below :)
Step-by-step explanation :
<u>We use Pythagoras' </u><u>theorem </u><u>:</u>
- In the triangle ABC we have :
AB² = AC² - BC² = 15² - 9² = 144 = 12²
- In the triangle ABD we have :
DB² = AD² - AB² = 13² - 12² = 5²
cos(a) = BD/AD = 5/13
