Answer:
x = ±1
Step-by-step explanation:
Step 1: Define variables
f(x) = x² + 1
f(x) = 2
Step 2: Substitute
2 = x² + 1
Step 3: Solve for <em>x</em>
0 = x² - 1
0 = (x - 1)(x + 1)
x - 1 = 0
x = 1
x + 1 = 0
x = -1
∴ x = ±1
Answer:
Step-by-step explanation:
Mean: You just add them altogether then divide the sum by how many numbers there are
Median: You put all the numbers from least to greatest then cross one off on the left and do the same on the right and repeat until there is either one or two numbers left if there are two number then you find the mean of those two numbers, but if you only have one number left then that is your answer
Mode: You find which number is the most common for enstance if there are two 3 and one 4 then 3 would be your answer because there are more 3 than 4
Range: You take the highest number and the lowest number of the set and subtract them and then you have your answer
6000x = 135000; x ≈ 23.
We are required to have one fire extinguisher for every 6000 ft of space in the building; this means we need to find out how many 6000-ft spaces we have in 135000.
Solving this equation, we divide both sides by 6000:
6000x/6000 = 135000/6000 = 22.5 ≈ 23
The answer is d because if you compare feet to yards 3 feet= 1 yard so divide 630 and 285 by 3 and then multiply them which ends up in 19,950. Your Welcome!
