The parabola is opens upward.

 a = (8 – 5)

= 3

Using the standard form:

(x – h)^2 = 4a(y – k)

(x -5)^2 = 12( y – 4)

In general form

x^2 -10x +25 =12y – 48

x^2 -10x -12y + 73 =0

mel-nik [20]

Step-by-step explanation:

The scientific notation of any number is given by :

N=a\times 10^b

a is any real no and b is any integer

The scientific notation of 345,000,000 should be 3.45\times 10^8 but Jorden wrote 34.5×10⁷. He is incorrect. He should have shifted decimal before 4 such that power of 10 becomes 8.

The mean absolute deviation shows us how spread out the data is, so the larger the mean absolute deviation the higher the variability.

Both teams have players that are 76 inches tall, so the last two statements cannot be true.
