Answer:
7.5
Step-by-step explanation:
because 7.5 x 16 = 120
Answer:
The Length of AC is 17 units.
Step-by-step explanation:
Given:
BL = LC
AD = 24
AL = LD
AL = LD = half of AD = half of 24 = 12. { FJ bisect AD }
Also,
CD = 2 + LC
To Find:
AC = ?
Solution:
By Addition Property we have
LC + CD = LD ............{ L - C - D }
LC + ( 2 + LC ) = 12 ..........{substituting the given values}
∴ 2(LC) = 12 -2
∴ 2 (LC) = 10
∴ 
Again, By Addition Property we have
AC = AL + LC ................{ A - L - C }
AC =12 + 5
∴ AC = 17 units
∴ The Length of AC is 17 units.
The parabola opens in the direction of the focus.
Since the focus is above the vertex, it opens up.
I would go with j pls tell me if wrong and i will try again
