Step-by-step explanation:
Absolute error=14.7-13.0
=1.7m
Percentage error = 1.7/14.7 x 100%
=11.56462
=11.6%

You just have to divide then multiple by 100
Answer:
Correct answer: x₁ = - 3/2 + i √7/2 or x₂ = - 3/2 - i √7/2
Step-by-step explanation:
We will first transform the given equation:
x² + 4x = x - 4 ⇒ x² + 4x - x + 4 = 0 ⇒ x² + 3x + 4 = 0
This equation has no solutions in the set of real numbers but it has in the set of complex numbers.
We will solve this equation as follows:
x² + 3x + 4 = x² + 2 · x · 3/2 + (3/2)² - (3/2)² + 4
the first three terms formed the square of the binomial
(x + 3/2)² - 9/4 + 4 = (x + 3/2)² - 9/4 + 16/4 = (x + 3/2)² + 7/4 =
= (x + 3/2)² - ( - 7/4) = (x + 3/2)² - (i √7/2)²
we gradually transformed the given equation and get the square difference
(x + 3/2)² - (i √7/2)² = (x + 3/2 - i √7/2) · (x + 3/2 - i √7/2)
(x + 3/2 - i √7/2) · (x + 3/2 - i √7/2) = 0 ⇒
x + 3/2 - i √7/2 = 0 or x + 3/2 + i √7/2 = 0 ⇒
x₁ = - 3/2 + i √7/2 or x₂ = - 3/2 - i √7/2

Answer:
9000 metres
Step-by-step explanation:
He went on a 54 km hike. First, we have to find this distance in metres.
1 km = 1000 m
54 km = 54 * 1000 = 54000 m
He divided the distance evenly over 6 days.
To find how many metres he walked each day, we divide the total distance he hiked by the number of days spent. That is:
54000 / 6 = 9000 metres
He walked 9000 metres each day.
