Answer:
300%
Step-by-step explanation:
S = ab
S1 = 2a × 2b
S1 = 4ab
S1 = 400%ab
=>The area is increased by 300%
Answer:
Step-by-step explanation:
y = x^2 - x - 2 is a quadratic function. It's easily factorable: y = (x + 1)(x - 2). Setting this result equal to zero yields the x-intercepts: -1 and 2. This matches the x-intercepts shown on the graph.
The axis of symmetry, x = -b/(2a), derived from the coefficients 1, -1 and -2 of this particular function, is x = 1/2. This x = 1/2 is also the x-coordinate of the vertex. To find the y-coordinate of the vertex, we evaluate y = x^2 - x - 2 at x = 1/2, obtaining:
y = (1/2)^2 - (1/2) - 2, or y = 1/4 - 1/2 - 2, or -2 1/4. This does not quite agree with the y value (-2) shown in the diagram, but is close.
7/32
Keep the pattern going. A(n)=A(n-1)*-1/2
14, -7, 7/2, -7/4, 7/8, -7/16, 7/32
List five living things in your house (people, animals, plants) and how they interact.
Example: Me, mom, dad, plant, dog. Me and my mom talk and I help her. Same with me and my dad. They both help me. All three of us water and take care of the plant. We play with the dog, feed him, and walk him. The dog sometimes plays with the leaves on the plant.
