For a parabola that opens upward, it must be a quadratic equation whose coefficient of x2 is a positive number.
So, I'll say x2+5x+6.
Answer:
3
Step-by-step explanation:
2 +2 =4 -1 is 3
Answer:
Correct answer is option D. 96.4 yd.
Step-by-step explanation:
Please refer to the attached figure for labeling of the given diagram.
ABC is a triangle with the following labeling:
A is the hole, B is the Tee and C is the point where the ball is.
Sides are labeled as:

To find:
Side 
Solution:
Here, we have one angle and two sides . Third side of the triangle is to be found opposite to the given angle.
We can use cosine formula here to find the value of the unknown side.

Putting all the values:

So, the distance between the Ball and hole is 96.42 yd
Correct answer is option D. 96.4 yd.
We have the sum of cubes identity

and observing that 1 + 4 = 2 + 3, we have

and

Then

Alternatively, we have the well-known sum of cubes formula

The sum under the square root is this sum with
. Then

and so the square root again reduces to 15.
