Answer:
<u>The correct answer is Hypotenuse = 3.61 units (Rounding to two decimal places)</u>
Step-by-step explanation:
We can use the Pythagoras theorem formula for solving this questions. It can be expressed symbolically as follows:
Hypotenuse² = First leg² + Second leg²
"The amount of units comprising the hypotenuse squared is equal to the addition of the measure of both legs squared."
Hypotenuse² = First leg² + Second leg²
Hypotenuse = √(First leg² + Second leg²
)
Replacing with the real values:
Hypotenuse = √(3² + 2²
)
Hypotenuse = √(9 + 4
)
Hypotenuse = √13
Hypotenuse = 3.60555
<u>Hypotenuse = 3.61 units (Rounding to two decimal places)</u>
Answer:
conversion factor
Step-by-step explanation:
A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.
The complete factor of the expression
is
correct option is D.
<h3>What is a factorization?</h3>
It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The expression is
.
To solve the expression properly we have to take common (2x²). Then we have

The factor is
.

Answer:
Precambrian period
Step-by-step explanation:
Since the Great oxidation period = 2.4 Billion years ago era = Precambrian period.
Micro-fossils attributed to cyanobacteria are abundant during the Proterozoic that came later 2,5 billion years ago and ended 540 million years ago,
