Answer:
y = 
(x - 5)² - 2
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) = (5, - 2), thus
y = a(x - 5)² - 2
To find a substitute (7, 0) into the equation
0 = a(7 - 5)² - 2
0 = 4a - 2 ( add 2 to both sides )
2 = 4a ( divide both sides by 4 )
a = 
=
y = (x - 5)² - 2 ← in vertex form
Answer:
The radius of circle O is 8.5 Units
Step-by-step explanation:
Solution
The radius of a circle is refereed to as the half of the diameter.
Now,
On how to figure out the length of AB, we apply the Pythagorean's equation or formula which is given below
Thus,
a² + b² = c²
(15)² + (8)² = c²
225 + 64 = c²
√289 = √c²
Then
c = 17
What this shows is that AB is 17 units.
Since we have gotten the diameter, the next step is to divide into half the know the radius value
Therefore,
17 ÷ 2 = 8.5 Units
= 8.5 Units.
Answer:
55 degrees
I answered the question on AoPS and it said it was correct.
Answer:
17
Step-by-step explanation:
b(1) = 16
b(2) = b(2-1) +1
= b(1) +1
= 16+1
= 17
