<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>
<em><u>Solution:</u></em>
<em><u>Given is:</u></em>
We have to find the vertex and axis of symmetry
<em><u>The general equation is given as:</u></em>
Comparing with given equation,
a = 2
b = 0
c = -1
<em><u>The axis of symmetry is given as:</u></em>
Thus axis of symmetry is 0
The x coordinate of the vertex is the same
x coordinate of the vertex = 0
h = 0
The y coordinate of the vertex is:
k = f(h)
k = f(0)
Thus, y coordinate of the vertex is -1
Therefore, vertex is (0, -1)
Answer:
14x-24
Step-by-step explanation:
arc length = radius multiplied by angle in radians
radius = 7 angle = 90 degrees
90 degrees = 1.571 radians
7 × 1.571 = 10.997
AB is 10.997 or 11 inches long
Answer:
Step-by-step explanation:
x²y = k, where k is a real constant.
When x = 3.5, y = 8.
=> (3.5)²(8) = k, k = 98.
When y = 8/9,
we have x²(8/9) = (98).
=> x² = 110.25
=> x = 10.5 or x = -10.5.
Since we want the negative value,
the answer is x = -10.5.
Answer:
D ≈ 0.925926 g/cm³
Step-by-step explanation:
Density = Mass / Volume
Step 1: Define
M = 25 g
V = (3 cm)³ = 27 cm³
D = ?
Step 2: Substitute and Evaluate for Density
D = 25g / 27 cm³
D = 25/27 g/cm³
D ≈ 0.925926 g/cm³
