Answer:
x = 3 ± √5
Step-by-step explanation:
The expression (x - 3)² = 5 doesn't need completing the square to solve (this is the step after you finish completing the square):
Step 1: Square root both sides
x - 3 = ±√5
Step 2: Add 3 to both sides
x = 3 ± √5 = 0.76392, 5.23607
The absolute value of a number tells us how far away from 0 that number is...
death valley : | -282 | = 282....so this is 282 spaces from 0
mississippi river : | 279 | = 279...so this is 279 spaces from 0
so the mississippi river is closer to 0 then death valley
40 people is the answer to 5 pitchers if 1/8 of a pitcher serves one person.
Solve for x:
2 sin^2(x) = 1
Divide both sides by 2:
sin^2(x) = 1/2
Take the square root of both sides:
sin(x) = 1/sqrt(2) or sin(x) = -1/sqrt(2)
Take the inverse sine of both sides:
x = 2 π n_1 + (3 π)/4 for n_1 element Z or x = 2 π n_2 + π/4 for n_2 element Z or sin(x) = -1/sqrt(2)
Take the inverse sine of both sides:
Answer: x = 2 π n_1 + (3 π)/4 for n_1 element Z or x = 2 π n_2 + π/4 for n_2 element Z or x = 2 π n_3 + (5 π)/4 for n_3 element Z or x = 2 π n_4 + (7 π)/4 for n_4 element Z
1/2 x 2= 1
1/8 x 2= 1/4
3/8 x 2= 3/4
3/4 x 1/4 = 3/16
3/16 x 1 = 3/16
YOUR ANSWER IS 3/16 dry ingredients
