Let's call your number n. Twice your number is 2n. The product of your number and twice your number (so n multiplied by 2n) is 128.
Set up an equation:
n × 2n = 128
2n² = 128
Divide both sides by 2:
n² = 64
Square root both sides to isolate n:
n = 8
The question asks for half your number, so just half 8:
8 ÷ 2 = 4.
Half your number is 4.
The circumference of circle is 20.096 units
<em><u>Solution:</u></em>
Given that circle has a diameter with endpoints at (10, 8) and (5, 4)
To get the diameter, find the distance between the end points
<em><u>The distance between two points is given by formula;</u></em>

Here the points are (10, 8) and (5, 4)

Substituting the values we get,


Thus the diameter is 6.4 units
<em><u>The circumference of the circle is given by formula:</u></em>

Where "d" is the diameter of circle

Thus circumference of circle is 20.096 units
Natural ecosystems are able to maintain a vibrant diversity of life because they incorporate intricate recycling systems that conserve essential materials.
Answer:
5
Explanation:
15 minus the product of 5 times the difference of p minus 6
Writing expression:
15 - [5 x (p -6)]
Since p = 8, insert the parameters and solve;
15 - [5 x (8 - 6)]
= 15 - (5 x 2)
= 15 - 10
= 5
