Answer:
See attachment
Step-by-step explanation:
The given function is
.
This rational function has a vertical asymptote at where the denominator is zero.
The denominator
when 
There is vertical asymptote at 
The horizontal asymptote for this rational function is given by the ratio of the leading coefficient of the numerator to the leading coefficient of the denominator.

The horizontal asymptote is 
The graph of this rational function is shown in the attachment
Find the vertex using vertex formula
-b ÷ 2a -8 ÷ -2 x = 4 for y plug in
F(x) = -(4)² + 8(4) + 9
= -16 + 28 +9
= 12 + 9
= 21
(4,21)
vertex form
y = -(x - 4)² + 21
so that means it will flip down - means flip down
so vertex represents a maximum point
The answer for the following is B
Step-by-step explanation:
Given
Maria goal's is to Jog 17.4 miles
She runs 2.75 miles each day for 7 days
Total distance covered by her in 7 days

So, she covers more than what she had planned.
Therefore, she is successful in her plan.
Answer: Area = 28.2m²
Step-by-step explanation: The triangle YXZ is shown in the figure below.
Area of a triangle is calculated by the formula:

According to the figure, the base of this triangle is b = 8.3m.
Height is a perpendicular line created from one side and intersecting the opposite angle.
To determine the height, use trigonometric relations to angle 68:

h = 7.3*sin(68)
h = 7.3*0.93
h = 6.8
Now, area of triangle YXZ is

A = 28.2
Area of triangle YXZ is 28.2m².
