Answer:
Step-by-step explanation:
Using the distance formula, we see that the distance between (-4,4) and (-7,3) is .
Step-by-step explanation:multipy -4x and 4 by 2 were the 8x and the -8x would cancel then add and bring down answer of x=15
The numbers:
1, -3, 2, -9, 3, -15, 4, -21,
are not linear.
If it was linear:
4, 3, 2, 1, -3, -9, -15, -21
t = 1.94 seconds
we have to solve the following polynomial equation:
-16t² + 60 = 0
16t² = 60
t² = 60/16 = 3.75
t = √3.75 = 1.936491673 seconds
the equation also has another possible answer = -1.936491673 seconds, but since time cannot be negative, we have to dismiss that option
The mode is 10
