Hello,
As (2,-4) is the vertex, the parabola is y=k(x-2)²-4
As (3,-1,) is a point of the parabola:
-1=k*(3-2)²-4
==> k=3y=3(x-2)²-4 so, coefficient of x² is 3.
Answer:
2
Step-by-step explanation:
If you look on the said it says 4 would be 2 paper clips, so p = 2 [ correct me if i'm wrong ]
Answer:
1440°
Step-by-step explanation:
n = number of sides
n-2 x 180
10 - 2 = 8
8 x 180 = 1440°
Answer:
m ≤ 150
Step-by-step explanation:
Let the variable "m" = the McDonald family.
Note that "spends no more than" means that they can spend less than or equal to the number provided, but not greater than. The sign for "less than or equal to" is ≤. 150 is the limit.
Set the inequality:
<em>m</em> ≤ 150 is your answer.

Answer:
1/7
Step-by-step explanation:
If one child was born on a Monday, then we don't have to consider that when solving the question, as it asks if both children were born on a Monday.
Thus, we only need to find the probability that the second child is born on a Monday. Since there are 7 days in a week and equally likely that the child is born on any day, then the probability of the child being born on a Monday would be 1/7.
