Scientific Notation:<br> what’s (2.2 x 10 to the -4) - (3 x 10 to the 2)
Marrrta [24]

Answer:

2.23\times10^4

Step-by-step explanation:

In order to get the answer to this question you need to turn the scientific notations into standard form then subtract the two standard forms.

(2.2\times10^{-4})-(3\times10^2)

Turn the notations into standard form:

2.2\times10^{-4} = .00022

3\times10^2=300

.00022-300=22300

=22300

Turn into notation form:

22300 = 2.23\times10^{4}

Hope this helps.

The completely factored form of the provided polynomial is  (p -2) (p+ 2) (p² +4). The option 4 is the correct option.

<h3>What is polynomial?</h3>

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is a real number).

The polynomial equation given in the problem is,

p^4 - 16

Let the factor form of the polynomial is f(p). Thus,

f(p)=p^4 - 16\\f(p)=p^4 - 2^4\\f(p)=(p^2)^2- (2^2)^2

Using the formula of difference of squares, we get,

f(p)=(p^2-4)(p^2+4)\\f(p)=(p^2-2^2)(p^2+4)\\f(p)=(p-2)(p+2)(p^2+4)

Thus, the completely factored form of the provided polynomial is  (p -2) (p+ 2) (p² +4). The option 4 is the correct option.

ASAP PLEASE HELP AND EXPLAIN TOO!!!!!!
VARVARA [1.3K]
Looking at number 4, you first have to look at the information that you have:
On tuesday he practiced for 1 5/6 hrs
Monday he practiced for 7/10 hrs
He is supposed to practice for 1 1/4 hr.
You could write questions like:
How much more did Marco practice on Tuesday than he is supposed to practice?
This works because it does indeed involve subtraction, you would be subtracting the amount that he should have practiced from the amount of time that he did practice. 
If I didn't answer the question, please message me and I will clarify!
