Answer:
(x² - 9)(x² - 2) = 0
x = 3 or √2
Step-by-step explanation:
To factor a polynomial, you need to find two expression that when multiplied together using FOIL (first, outside, inside, last) will produce the polynomial. In this case the polynomial 
can be factored into:
(x² - 9)(x² - 2) = 0
Setting each of these expressions equal to '0':
x² - 9 = 0 or x² = 9 so √x² = √9 or x = 3
x² - 2 = 0 or x² = 2 so √x² = √2 or x = √2
Answer:
9-0+1-1×2

Answer:
B) curve
Step-by-step explanation:
A sine function will have a value of 1/2 infinity times. However, on the interval of a single period, a sine function will have a value of 1/2
one time.
What is the mean of the data set?
Data set:
393 ; 399 ; 402 ; 402 ; 407 ; 410 ; 424 ; 425 ; 428
393 + 399 + 402 + 402 + 407 + 410 + 424 + 425 + 428 = 3,690
3,690 / 9 = 410
The mean is 410. It is the average of all numbers.
What is the median of the data set?
Data set:
01 ; 03 ; 14 ; 15 ; 22 ; 35 ; 35 ; 43
There are 8 numbers, we need to get the sum middle 2 and divide it by 2 to get the median.
15 + 22 = 37
37/2 = 18.50
The median is 18.50
