Answer:
Step-by-step explanation:
Let's translate what you've written in words to an expression with mathematical symbols.
To solve this, you need to multiply both the numerator and denominator with the conjugate of the denominator.
At the start of 2014 Lucy's house was worth ?200000 the value of the house increased by 5% every year work out the value of her
1 answer:
Answer:
$231525.00
Step-by-step explanation:
We know that the formula to calculate the increase at a certain growth rate is,
Where, is the value of house at the start of 2017
is the value of her house in 2014
<em> 'i' </em>is the rate at which value is increasing
<em>n </em>is the number of years (periods).
From 2014 to 2017 it is 3 years, so <em>n</em> = 3.
Putting the values we get,
So the value of her house at the start of 2017 will be $231525.00
(I have assumed that the valuation is done in dollars).

If the midpoint of segment lm where j(5, -1) and m(0, 6), then the coordinates of end point l is (10,-8)..
Midpoint:
Midpoint of a line segment is the point that is halfway between the endpoints of the line segment.
The formula for the midpoint is,
where,
= coordinates of the midpoint
(x₁, y₁) = coordinates of the first point
(x₂, y₂) = coordinates of the second point
Given,
Midpoint = j = (5,-1)
Second point = m = (0,6)
Now, we have to find the first midpoint l.
Let (x,y) be the coordinates of l.
Then apply the values on the formula,
Then we get,
Compare the values in order to find the coordinates,
=> 5 = (x + 0) / 2
=> 5 x 2 = x + 0
=> 10 = x
Similarly,
=> -1 = (y + 6) / 2
=> -1 x 2 = y + 6
=> -2 = y + 6
=> -2 - 6 = y
=> y = -8
Therefore, the coordinates of l is (10,-8).
