Answer:
Opening: Opens upwards
Axis of Symmetry: -7/2
Vertex: (-7/2, -81/4)
X - intercepts: (1, 0) and (-8, 0)
Y - intercept: (0, -8)
Step-by-step explanation:
Opening: 'a' is greater than zero
Axis of Symmetry:
Vertex:
X - intercepts:
(x-1)(x+8)
x = 1 and x = -8
Y - intercept: (0, -8)
$2.03 is the closest for being equivalent to 2
Below is the answer:
Any rectangle with a side against y-axis can be rotated about y-axis to create a cylinder.
<span>The other 3 coordinates will be (a, 3), (a, b), (0, b) </span>
<span>This will be a cylinder of radius a and height |3−b|</span>
Answer:
this question is weirdly worded. i think you meant to type "three angles of a hexagon....." I'll do my best.
Step-by-step explanation:
sum of angles in a polygon: (n-2) 180° where n=#of sides of the polygon
(6-2) 180°
(4) 180°
720°
1a + 1a + 1a + 0.5a + 0.5a + 0.5a = 720°
4.5a = 720°
a = 720°/4.5
a = 160
0.5a = 80
Check
3(160) + 3(80)
480 + 240 = 720
<h3>This cylinder is 8 inches tall and has a volume of 200 π in³. Find the area of the cross section.</h3>
Answer: cross section = 25π in²
Step-by-step explanation:
Cylinder volume is the product of the cross section by height.
Then cross section = cylinder volume/height = 200 π in³/8in = 25π in²
Answer: 25π in²
