Alright, it went 1 to the right and down 2 times.

So for point B, you calculate the opposite.

Point B goes 1 left while going up by 2.

(9 - 1, 3 + 2) = (8, 5)

Pre-image point A is (8, 5)

Find the multiplicative inverse of 3 − 2i. Verify that your solution is corect by confirming that the product of

leonid [27]

Answer:

$\frac{3}{13} + \frac{2i}{13}$

Step-by-step explanation:

The multiplicative inverse of a complex number y is the complex number z such that (y)(z) = 1

So for this problem we need to find a number z such that

(3 - 2i) ( z ) = 1

If we take z = $\frac{1}{3-2i}$

We have that

$(3- 2i)\frac{1}{3-2i} = 1$ would be the multiplicative inverse of 3 - 2i

But remember that 2i = √-2 so we can rationalize the denominator of this complex number

$\frac{1}{3-2i } (\frac{3+2i}{3+2i } )=\frac{3+2i}{9-(4i^{2} )} =\frac{3+2i}{9-4(-1)} =\frac{3+2i}{13}$

Thus, the multiplicative inverse would be $\frac{3}{13} + \frac{2i}{13}$

The problem asks us to verify this by multiplying both numbers to see that the answer is 1:

Let's multiplicate this number by 3 - 2i to confirm:

$(3-2i)(\frac{3+2i}{13}) = \frac{9-4i^{2} }{13} =\frac{9-4(-1)}{13}= \frac{9+4}{13} = \frac{13}{13}= 1$

Thus, the number we found is indeed the multiplicative inverse of 3 - 2i

There are 30 major league baseball teams and 32 national football league teams. The expanded roster for the Major League teams i

nikdorinn [45]

Answer:

<em>The National football league has </em><em>464 more players</em><em> than the Major League baseball.</em>

Step-by-step explanation:

Since there are 30 teams in the Major league baseball and there are 40 players in each team, this means that the total number of players in the Major league baseball is:

30 × 40 = 1200 players

Since there are 32 teams in the National football league and there are 52 players in each team, this means that the total number of players in the National football league is:

32 × 52 = 1664 players

Therefore, the difference in the number of players in both leagues is:

<em>1664 - 1200 = 464 players</em>

<em></em>

Therefore, the National football league has <em>464 more players</em> than the Major League baseball.
