Answer:
Option (D)
Step-by-step explanation:
Pythagoras theorem states,
(Hypotenuse)² = (leg 1)² + (leg 2)²
(13)² = (5)² + (12)²
By the converse of Pythagoras theorem,
If we draw two sides 5cm and 12cm of a triangles with a right angle between them, third side 13 cm will fit to form a right triangle.
Therefore, Option (D) will be the answer.
Answer:
4+√55= 11.42
4-√55= -3.42
Step-by-step explanation:
- w² − 8w − 39 = 0
- w²- 2*4w + 16- 55=0
- (w-4)²=55
- w-4=√55 ⇒ w= 4+√55= 11.42
- w-4=- √55 ⇒ w= 4-√55= -3.42
To solve this problem you must apply the proccedure shown below:
1. The vertex i at <span>(0, 36) and a focus at (0, 39), then you have:
a=36
a^2=1296
2. The directrix is:
y=a^2=c
c=39
y=1296/39
</span>y=432/13<span>
Therefore, the answer is the option D, which is: </span><span>D. y=± 432/13</span>
