By definition we have to:
Scientific notation, also called pattern or notation in exponential form, is a way of writing numbers that accommodate values too large or too small to be written in a conventional manner.
The use of this notation is based on powers of base 10.
A number written in scientific notation follows the following pattern:
![m * 10 ^ e ](https://tex.z-dn.net/?f=m%20%2A%2010%20%5E%20e%0A)
The number m is called "mantissa" and e the "order of magnitude"
For this case we have:
0.000007
Using the definition, we have that the measure of the diameter in scientific notation is:
Answer:
An expression that represents this diameter, in meters in scientific notation is:
Answer:
x^2 -6x + 222/25
Step-by-step explanation:
If the zeros are as above, then ;
x = 3-√3/5 or x = 3 + √3/5
Firstly, let’s represent √3/5 by b
Thus;
The two roots are ;
x = 3-b or x = 3 + b
so;
x+ b -3 and x -3-b
The quadratic equation is the product of the two
(x + b-3)(x - b -3)
x(x - b-3) + b(x -b -3) -3(x - b -3)
= x^2 -bx -3x + bx -b^2 -3b -3x + 3b + 9
Collect like terms and we are left with;
x^2 -6x -b^2 + 9
So let’s put back b = √3/5
x^2 -6x -(√3/5)^2 + 9
x^2 -6x -3/25 + 9
x^2 -6x + 222/25
4.5(4-x) + 36 = 202 - 2.5(3x + 28)
Distributive property
18 - 4.5x + 36 = 202 - 7.5x - 70
Combine like terms
-4.5x + 54 = -7.5x + 132
Add 7.5x to both sides
3x = 78
Divide both sides by 3
x = 26
Number of matchsticks required is 2. Rule which matchstick pattern is 2 x n.
Diagonal angles have the same measure - not sure what u mean by oposite.
