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:
The diameter of circle is 24 cm.
Step-by-step explanation:
We are given the following in the question:
Circumference of circle = 75.36 cm
We have to find the diameter of the circle.
Circumference of circle =
where r is the radius of the circle.
Putting values, we get,
Diameter of circle =
Thus, the diameter of circle is 24 cm.
