I believe the correct answer from the choices listed above is option A. If DF+FE=DE, then point F is <span>A. a midpoint of DE (with line over). F is the endpoint of line segment DF and is the starting point of line DE thus it is in between line DE. Hope this answers the question.</span>
Answer:
D
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, - 1), thus
y = a(x - 8)² - 1
To find a substitute (0, - 17), the coordinates of the y- intercept into the equation.
- 17 = a(0 - 8)² - 1
- 17 = 64a - 1 ( add 1 to both sides )
- 16 = 64a ( divide both sides by 64 )
a = 
= - 
y = - (x - 8)² - 1 → D
Answer:
Dimensions of the square garden = 9 meters by 9 meters
Dimensions of the triangular garden = 12 meters
Step-by-step explanation:
Let the measure of a side of the square garden = x meters
Perimeter of the square = 4x meters
Since each side of the triangle is 3 meters longer than each side of the square, side of the triangle will measure = (x + 3)
Perimeter of the equilateral triangle = 3(x + 3) meters
Perimeter of the square = perimeter of equilateral triangle
4x = 3(x + 3)
4x = 3x + 9
4x - 3x = 9
x = 9 meters
Dimensions of the square garden = 9 meters by 9 meters
Dimensions of the triangular garden = 12 meters
