D. ft²
Step-by-step explanation:
Scientific notation of a number is expressed in the following form,
Where,
a = decimal number (1 ≤ |a| < 10)
b = the power of 10 whereby the scientific notation is equivalent to the original number.
To express 4,356,000 square feet in scientific notation, do the following:
1. Move the decimal point to the left up to the last non-zero digit = a = 4.356
2. Since we moved the decimal point by 6 decimal places, therefore, b = 6
3. Substitute the values of the variables into
Thus:
4,356,000 = 3. Substitute the values of the variables into
a * 10^b
Thus:
4,356,000 = 4.356 * 10^6
Answer:
Yes, the set of numbers create a Pythagorean triple
Step-by-step explanation:
we know that
If a set of numbers create a Pythagorean triple, then the set of numbers must satisfy the Pythagorean Theorem
where
c is the greater side
a and b are the legs (perpendicular sides)
we have
substitute
----> is true
therefore
Yes, the set of numbers create a Pythagorean triple
