Answer:
Step-by-step explanation:
Your "y=2xsquared-12x+10" translates into y = 2x^2 - 12x + 10. This factors into y = 2(x^2 - 6x + 5).
Setting this = to 0 results in y = 2(x - 5)(x - 1) = 0, so that the x-intercepts are (5, 0) and (1, 0). The x-coordinate of the vertex lies halfway between x = 1 and x = 5, that is, at x = 3. Using synthetic division to evaluate y = 2x^2 - 12x + 10 at x = 3, we get
3 2 -12 10
6 -18
------------------
2 -6 -8
Therefore, the vertex is located at (3, -8).
Setting x = 0 results in the y-intercept: y = 2(0)^2 - 12(0) + 10 => (0, 10)
Answer:
the other two sides are 31.11 feet and 31.11 feet
Step-by-step explanation:
since two angles are 50°, the triangle is isosceles with the other two sides being equal in length.
A right triangle is formed by a line from its peak down & perpendicular to
the 40 foot side. It's hypotenuse is the unknown (x) and it's base is 40/2 = 20 feet.
cos 50 = 20/x
0.6428 = 20/x
x = 31.11 feet
Answer:
$8 dollars.
Step-by-step explanation:
There are four people: London, Katerina, Layla, and Tony.
We know that the total is $32 dollars so we simply have to divide 32 by 4 which will give us an answer of 8.
Hope this helps!
