Answer:
A.
Step-by-step explanation:
To divide the complex number: , we rationalize with the conjugate of the denominator.
This gives us:
We apply the distributive property to get:
We simplify to get:
This implies that:
The correct answer is A.
In a standard deck of cards, there are 13 diamond cards and 39 non diamonds. To choose 3 diamonds from 13 cards would be equivalent to 13*12*11 as there are less cards to choose from each time you remove a card. To choose two non diamonds from the other non diamonds cards would be equivalent to 39*38, taking into account the number of cards you remove each time you pick out one card. Hence the total number of ways is 13x12x11x39x38.
Answer:
The equation is 19+3.5h=10+4.75h. The answer is 7.2 hours.
Step-by-step explanation:
The equation for this problem would be 19+3.5h=10+4.75h. All you have to do is find h. So subtract 3.5h from both sides and 10 from both sides. You will get the equation 1.25h=9. Divide 1.25 from both sides and you will end up with h=7.2 hours.

<u>Trigonometric Identities</u>
The basic trigonometric identity is:
We'll use it and some basic algebra to prove that, given:
And
Then
From the equation:
We have:
The equation
Can be rewritten as
Replacing [1]:
Taking the common factor:
The expression in parentheses is 1, thus:
Dividing by
Replacing in
We have
Dividing by
Now:
This expression is 1, thus it's proven:
A) your model would be 725 blocks tall because 1,450/2=725
B) your model would be 290 blocks tall because 1,450/5=290.
C)reduction of the Empire State Building because you are building a model that takes blocks representative of a larger unit than what it signifies
D)don’t have the table to fill in
