Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (8, - 14), thus
y = a(x - 8)² - 14
To find a substitute (5, 13) into the equation
13 = a(5 - 8)² - 14
13 = a(- 3)² - 14
13 = 9a - 14 ( add 14 to both sides )
27 = 9a ( divide both sides by 9 )
a = 3
Thus
y = 3(x - 8)² - 14 → C
Sounds like a good deal to go swimming!
The answer is A because if you do the 40 dagree and a coodinate plane it forms a triangle.
X = √7²+4² by using Pythagoras Theory as the triangle is a right angled triangle
Answer: C
Explanation: The y-intercept which is -9 matches with the equation and the slope matches too
