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.
Answer: 61,750 miles
Step-by-step explanation:
Given : The p-value of the tires to outlast the warranty = 0.96
The probability that corresponds to 0.96 from a Normal distribution table is 1.75.
Mean : 
Standard deviation : 
The formula for z-score is given by : -
Hence, the tread life of tire should be 61,750 miles if they want 96% of the tires to outlast the warranty.
Answer:
$5.72
Step-by-step explanation:
The easiest way to do this is take the two deposits and add them together then combine with the original balance.
Add 5.72 and 16.75
5.72+16.75=22.47
Then subtract -16.75 from 22.47
22.47-16.75=5.72
Answer:
45
Step-by-step explanation:
The absolute value of negative 5 is 5 because it is five units away from zero, and then 9x5=45.
