Answer: 9 3/8 of turquoise
3 1/8 of navy blue
Step-by-step explanation:
3 1/2 + 1 1/6 = 4 2/3
12.5 divided by 4 2/3 = 2 19/28
2 19/28 x 3 1/2 = 9 3/8 turquoise
2 19/28 x 1 1/6 = 3 1/8 navy blue
Checking:
9 3/8 + 3 1/8 = 12.5
Answer:
2x^2+85x+13
Step-by-step explanation:
I did not knew what you wanted, but I think this is what you wanted.
For left put 2 on each
On the box over 100 put 82, and put 82 in the box on the right
Below are suppose the be the questions:
a. factor the equation
<span>b. graph the parabola </span>
<span>c. identify the vertex minimum or maximum of the parabola </span>
<span>d. solve the equation using the quadratic formula
</span>
below are the answers:
Vertex form is most helpful for all of these tasks.
<span>Let </span>
<span>.. f(x) = a(x -h) +k ... the function written in vertex form. </span>
<span>a) Factor: </span>
<span>.. (x -h +√(-k/a)) * (x -h -√(-k/a)) </span>
<span>b) Graph: </span>
<span>.. It is a graph of y=x^2 with the vertex translated to (h, k) and vertically stretched by a factor of "a". </span>
<span>c) Vertex and Extreme: </span>
<span>.. The vertex is (h, k). It is a maximum if "a" is negative; a minimum otherwise. </span>
<span>d) Solutions: </span>
<span>.. The quadratic formula is based on the notion of completing the square. In vertex form, the square is already completed, so the roots are </span>
<span>.. x = h ± √(-k/a)</span>
