Answer:
Volume of a cone: 1/3 x base x height
Volume of a cylinder: π x height x diameter
Hope this helps ;)
You can use this method: part = percent •whole.
Your percent is .30 and your part is 9.
9=.3x
You now divide 9 by .3 which is 30. His total time is 30 minutes. Now you need to subtract how many minutes be played already from his total play time. 30 - 9 would be 21. He has 21 more minutes to play.
Answer:
(- 2, 9 )
Step-by-step explanation:
Given a parabola in standard form, y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - ![\frac{b}{2a}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7B2a%7D)
y = - x² - 4x + 5 ← is in standard form
with a = - 1 and b = - 4, thus
= -
= - 2
Substitute x = - 2 into equation for corresponding y- coordinate
y = - (- 2)² - 4(- 2) + 5 = - 4 + 8 + 5 = 9
vertex = (- 2, 9 )
Answer:
Axis of symmetry: x = –1; Vertex: (–1, 0); f(x) = –2x2 – 2x – 1
Step-by-step explanation:
What are the vertex and axis of symmetry of the equation?
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .
1) Venn Diagram is used to organize data
2) Four circles. Three intersection circles, and one which contains other three circles
3) In the intersection area of three circles.
4) In the circle which contains other three circles, but not inside any of the intersecting circles.
