Find the x-intercepts of the parabola with vertex (1,-17) and y-intercept (0,- write your answer in (x1,y1) , (x2,y2).

To solve this problem you must apply the proccedure shown below:

1. You have that the standard form of the equation for a parabola is:

Where is the vertex

2. Substitute the values shown into the equation:

3. Now, substitute and to calculate :

4. Then, the equation of the parabola is:

5. To calculate the x-intecept must be . Substitute it into the equation and solve for :

The answer is:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
