Answer:
The number would have to be added is 2
Step-by-step explanation:
To find the form of the completing square of the quadratic function:
- Divide the coefficient of x by 2
- Subtract the numerical term from the square of the quotient
Let us do these steps with our question
∵ x² - 2x - 1 = 0
→ Divide the coefficient of x by 2
∵ The coefficient of x is -2
∴ -2 ÷ 2 = -1
→ Square the -1
∵ (-1)² = 1
→ Subtract the numerical term from 1
∵ The numerical term = -1
∵ 1 - (-1) = 1 + 1 = 2
∴ We must add 2 to -1 to get 1
→ (x² - 2x - 1 + 2) - 2 = 0
→ (x² - 2x + 1) = 2
→ (x - 1)² = 2
The number would have to be added is 2
Answer:
the correct answer is 8,000ft
Step-by-step explanation:
sin30°=4000ft/h
hsin30°=4000ft
h=4000ft/sin30°
h= 8,000ft
Answer:B
Step-by-step explanation:
Answer:
1.12 × 10^-3
Step-by-step explanation:
The computation of the width of the photograph is as follows:
As we know that
Area of the rectangle = length × width
33 ÷ 20 square inches = 1475 inches × width
So, the width is
= Length ÷ area
= 1475 inches ÷ (33 ÷ 20 square inches)
= 1.12 × 10^-3
