Answer:
Step-by-step explanation:
From your knowledge of multiplication tables, you know ...
48 = 6·8 = 3·2·2·2·2 = 3·2^4 . . . . a = 4
56 = 7·8 = 7·2·2·2 = 7·2^3 . . . . . . b = 3
Answer:
24 cm²
Step-by-step explanation:
We assume that is a circumscribing quadrilateral, rather than one that is circumscribed. It is also called a "tangential quadrilateral" and its area is ...
K = sr
where s is the semi-perimeter, the sum of opposite sides, and r is the radius of the incircle.
K = (12 cm)(2 cm) = 24 cm²
_____
A quadrilateral can only be tangential if pairs of opposite sides add to the same length. Hence the given sum is the semiperimeter.
i)
Axis of symmetry:
x = - 2 (the value of x vertex)
ii)
Vertex:
The vertex of a parabola is the point where the parabola crosses its axis of symmetry.
The vertex (-2, -4)
iii)
Domain:
All real number
iv)
Range: y >= - 4 (the vertex is the lowest point on the graph, it has minimum value and opens up)
