Answer:
Step-by-step explanation:
f(x) = 2x^2 - x - 10
Part A:
x-intercepts: (-2,0), (5/2,0)
Part B:
The vertex is the minimum
vertex: (1/4, -81/8)
Part C:
A:
x: -2, -1, 1/4, 1, 2
y: 0, -7, -81/8, -9, -4
B:
Answer:
1/ 112
Step-by-step explanation:
1-½ = ½ ( Mr. Daniel's leftover)
½×½= ¼ ( Mr. Richie)
½×¼= 1/8 ( Ms Laura)
½×1/8 = 1/16 ( Ms. Kimberly)
1/7 × 1/16 = 1/ 112 (the last turn)
so, Ms. Sarah eats 1/ 112 of a piece.
Answer:
Step-by-step explanation:
We can use the double angle identity for sine.
The given expresion is
We apply the identity to get:
We simplify to obtain;
This simplifies to:
The correct answer is D
The segment was only rotated, not changed. It would be the same length as the original.
To find the length, use the distance formula.
(5, 8) would be point 1.
(-6,8) would be point 2.
Plug them into the formula.
Simplify.
Square root this answer.
Negative distances aren't possible, so your answer is 11.
Hope this helped!
