Answer:
1/15
Step-by-step explanation:
5+3+2 = 10
Chance of pulling out a yellow marble = 3/10
Once you pull out the marble there are 9 marbles left, 2 yellows, 2 blacks and 5 whites.
Chance of then pulling out a black marble = 2/9
3/10 x 2/9 = 6/90
6/90 = 1/15
Given equation: y =2x^2+12x+13.
We need to find the axis of symmetry and the coordinates of the vertex of the graph of the function.
The formula of axis of symmetry is : .
a= 2 and b=12.
Therefore, .
<h3>Therefore, axis of symmetry is x=-3.</h3>
Let us find y-coordinate of the vertex.
Plugging x=-3 in given quadratic y =2x^2+12x+13.
y= 2(-3)^2+12(-3)+13 = 2(9) -36 +13 = 18-36 +13 = -5.
We got x-coordinate of the vertex -3 and y-coordinate of the vertex -5.
<h3>Therefore, vertex of the graph is (-3,-5).</h3>
Answer:
r = - 3
Step-by-step explanation:
Given
40 = 16 - 8r ( subtract 16 from both sides )
24 = - 8r ( divide both sides by - 8 )
- 3 = r
