Answer:
Juliette answered 72 questions correctly
Step-by-step explanation:
48% of 150 = 72
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)
A= 3631.68
Step-by-step explanation:
the formula to find the surface area is A=2πrh+2πr^2 so when you substitute all your radius values and height values, you get approximately 3631.68
Expand the brackets. two negatives multiplied together make a positive and a positive and a negative multiplies together make a negative. so you would times everything in the first bracket by -4 and everything in the second bracket by -4 also because it also has a -4 outside the bracket:
4y-4v-20v+4y
