Answer: $250
Step-by-step explanation:
The computer reduces by half of its value every year. It is originally valued at $4,000 so the value in 4 years can be calculated by the formula:
= 4,000 * 0.5 ^ number of years
= 4,000 * 0.5⁴
= $250
Another method is to reduce by half every year:
First year = 4,000 / 2 = $2,000
Second year = 2,000 / 2 = $1,000
Third year = 1,000 / 2 = $500
Fourth year = 500 / 2 = $250
<em><u>Recursive equation for the pattern followed is given by,</u></em>
In the question,
The number of interaction for 1 child = 0
Number of interactions for 2 children = 1
Number of interactions for 3 children = 5
Number of interaction for 4 children = 14
So,
We need to find out the pattern for the recursive equation for the given conditions.
We see that,
Therefore, on checking, we observe that,
On checking the equation at the given values of 'n' of, 1, 2, 3 and 4.
<u>At, </u>
<u>n = 1</u>
which is true.
<u>n = 2</u>
Which is also true.
<u>n = 3</u>
Which is true.
<u>n = 4</u>
This is also true at the given value of 'n'.
<em><u>Therefore, the recursive equation for the pattern followed is given by,</u></em>
Answer:
y = 3x - 10
Your problem setup is correct. The triangle is isosceles, so the marked segments are the same length.
3x - 8 = 2x
You can solve this by subtracting 2x (from both sides) ...
x - 8 = 0
Then adding 8 (to both sides):
x = 8
MB = MA = 2x = 16.
