Answer:
No one ate more
Step-by-step explanation:
Olivia and Hudson each have an apple.
Olivia cuts her apple into halves and eats one piece.
1 ÷ 2 = +
Now she ate one piece =
Hudson cuts his apple into quarters and eats two pieces.
1 ÷ 4 = +
+
+
He ate 2 pieces = +
=
Therefore, No one ate more. They ate the same amount of apple.
Surface area of the square pyramid = 217.8 in²
Solution:
Side length of the square = 9 in
Area of the square = side × side
= 9 in × 9 in
= 81 in²
Area of the square = 81 in²
Perimeter of the base = 4 × 9 in = 36 in
Slant height of the triangle = 7.6 in
Surface area of the square pyramid
= 217.8 in²
Surface area of the square pyramid = 217.8 in²
if we zero out f(x), namely make y = 0, we can get the roots or x-intercepts for this quadratic equation
now, the equation is in x-terms, meaning is a vertically opening parabola, so the axis of symmetry will be x = something, a vertical line.
well, we have two x-intercepts, one at -4 and another at 2, and the vertex is right half-way between those guys
-4------------(-1)------------2
so the vertex is at x=-1, namely the axis of symmetry is x = -1.
