Answer:
Step-by-step explanation:
Vertex form of the quadratic equation: 
where the vertex is 
Given vertex = (6, 5):
If one the x-intercepts is (8, 0):
Therefore, equation of parabola:
x-intercepts occur when f(x) = 0:
Therefore, the x-coordinate of the other x-intercept is 4.
The angle of elevation is = 70° and the distance the airplane travelled in the air is = 17,557ft
<h3>Calculation of the distance travelled</h3>
- To calculate the angle of elevation of the airplane
tan x° = opposite/adjacent
where opposite = 16,500 feet
adjacent = 6,000 ft
tan x° = 16,500 / 6,000
tan x° = 2.75
X = arctan ( 2.75)
X = 70°
- To calculate the distance the airplane travelled in the air Pythagorean Theorem is used.
C² = a² + b²
C² = 16,500² + 6,000²
C² = 272250000 + 36000000
C² = 308250000
C= √308250000
C= 17,557ft

Answer:
13.25
Step-by-step explanation:
the answer is c because you'd have to multiply 75 and 9 to get 13.25 which is c if add would be the same thing
Two lines that intersect have 1 solution
