Answer:
Your lowest point should be 26, and highest at 56, since that's your min and max value. Your median should be 40. Your Q1 should be 29, and Q2 should be 47.5
615.44 because area of a circle=pi×radius^2
Given:
The equation of a quadratic function is:
To find:
The equation of the axis of symmetry for the given function.
Solution:
If a quadratic function is , then the equation of the axis of symmetry is:
...(i)
We have,
Here, . So, the equation of axis of symmetry by using (i), is
Therefore, the correct option is C.
To find the length of the altitude, we have to use the ratios of the similar sides.
Let the length of altitude=x
Ratio of sides:
So length of altitude is 9 cm.
Answer: 9 cm
Answer:
r = 2
Step-by-step explanation:
Calculate slope m using the slope formula and equate to
m =
with (x₁, y₁ ) = (- 11, r) and (x₂, y₂ ) = (- 7, 5)
m = = = ( multiply both sides by 4 to clear the fractions )
5 - r = 3 ( subtract 5 from both sides )
- r = - 2 ( multiply both sides by - 1 )
r = 2
