2x^2 + 9x + 4 = 0
x^2 + 9/2*x + 2 = 0
x = - 9/4 +- √(81/16 - 32/16) = - 9/4 +- 7/4
x1 = - 1/2
x2 = - 4
It looks like the first and the third are diagrams of similar triangles, and the third needs another right angle marker at E to be persuasive. So I'll go with
First diagram
We're given a congruent angle pair and we have another from vertical angles, so AA, similar triangles.
<span><u>C. $24 ÷ 8 </u>because 24 divided by 8 is 3 and $3 times 8 hot dogs is $24
so you answer is C</span>
Answer:
Step-by-step explanation:
we know that
The height of Justin’s rocket is modeled by the equation
This is the equation of a vertical parabola open downward
The vertex is a maximum
where
The coefficient of t^2 represent the acceleration
The coefficient of t represent the initial velocity
The constant of the equation represent the initial height
Remember that
Elena launched his rocket from the same position, but with an initial velocity double that of Justin’s
so
Now the initial velocity is
substitute
The height of Elena’s rocket is the equation
