Answer:
No matter the number, the tenths place is the first to the right of the decimal point. In numbers with no decimal point, the tenths place is zero.
Step-by-step explanation:
Answer:
Because it is a tenth of one whole
Step-by-step explanation:
When one is divided by ten, it is called a tenth, a piece of a whole
axis of symmetry:
vertex:
Answer:
Axis of symmetry: –3
Vertex: (–3, –5)
Step-by-step explanation:
For a quadratic function in standard form, the axis of symmetry is a vertical line . Therefore:
For the vertex, –3 is the x-coordinate and we solve for y to find the y-coordinate:
y = 2x² + 12x + 13
y = 2(–3)² + 12(–3) + 13
y = 2(9) + 12(–3) + 13
y = 18 – 36 + 13
y = –5
Therefore, the vertex is (–3, –5).
