Answer:
approximately 1,148,000
Step-by-step explanation:Round 2,803 to 2,800 and 406 to 410 then multiply 2,800 by 410
Step-by-step explanation:
64/(1+1+2)
= 64/4
= 16
1 : 1 : 2
mark = 1×16 = 16
dave = 1×16 = 16
ralph = 2×16 = 32
Answer:
38 is the correct solution
Answer:
12, -12
Step-by-step explanation:
sqrt(144)
What number times itself = 144
12*12 = 144
Also -12*-12 = 144
This is a parabola, first, locate the line of symmetry.
the line of symmetry is x=-b/2a
in this case, b=-2, a=-1, so the line of symmetry is x=-1
when x=-1, f(x)=-(-1)²-2(-1)-3=-2
locate the point (-1,-2) on the grid. this point is the vertex.
get two pairs of points with x=-1 as the symmetry line:
(0, -3) and (-2, -3); (1,-6) and (-3,-6)
connect these five points into a parabola, stick out at the ends because it will extend forever downward.
