Answer: 0.0066248

Step-by-step explanation:

7.28⋅10−2)⋅(9.1⋅10−2)

7.28⋅9.1⋅10−4

66.248⋅10-4

Answer:

A) 6.6248 x 10^-3

Step-by-step explanation:

You first do the exponents of the 10s

(7.28 x 10^-2) = (7.28 x 0.01) , (9.1 x 10^-3) = (9.1 x 0.01)

Then multiply the parentheses

(7.28 x 0.01) = 0.0728 , (9.1 x 0.01) = 0.091

Then multiply both products together

0.0728 x 0.091

= 0.0066248

In order to simplify this into an equation you can count the amount of decimal placements you would need to move make a whole number, then the amount of placements is your exponent, in this case it is 3. Then since they're all 0s you use the base of 10 and since the value is shrinking you sue a negative exponent

0.006248-----> 6.6248 x 106-3

A quadratic equation has exactly one real number solution. Which is the value of its discriminant? −1 0 1 2

lutik1710 [3]

<u>Answer:</u>

The correct answer option is 0.

<u>Step-by-step explanation:</u>

We know the quadratic formula that we use to find the roots of a quadratic equation:

$\frac{-b+-\sqrt{b^2-4ac} } {2a}$

The discriminant in this formula is the part underneath the square root symbol i.e. b^2-4ac.

For a quadratic equation to have exactly one real number solution, the discriminant must be zero.

As we can see the + and - sign appearing before the discriminant here so for one real number solution, these plus and minus signs need to be removed which can only happen if we have a value of zero.

What is the prime factorization of 84

V125BC [204]

Prime factorization is breaking down a number into factors until it is composed/simplified into only prime numbers.
For example, 32.
32 : 2 x 16, 4 x 8
Now break down the factors.
2 x 2 x 8 (16)
2 x 2 x 2 x 2 x 2 = 32 in prime factorization.
Now that I've explained this (please ask questions in pm if you need me to explain it better), we can find the prime factorization of 84.
84 = 2 x 42
2 x 2 x 21
2 x 2 x 3 x 7 = 84.
2 x 2 = 4
4 x 3 = 12
12 x 7 = 84.
The prime factorization of 84 is:
2 x 2 x 3 x 7
I hope this helps!
