There are 16 combinations.

The easy way to figure this out is square the number. In this case, it's 4.

4^4=16

I hope this helps and I got it right for you!

If z7=4-3i, thenz7 is<br> Select one:<br> O-7<br> O 7<br> O 5<br> O -5

Orlov [11]

By using Euler's notation, we will see that:

z^7 = 78,125*e^(-i*4.48)

We know that:

z = 4 - 3i

Remember that for a complex number:

w = a + bi

In Euler's notation, we can write this as:

w = √(a^2 + b^2)*e^(i*Atan(b/a))

Then, for z, we will get:

z = √(4^2 + (-3)^2)*e^(i*Atan(-3/4))

z = 5*e^(-i*0.64)

Now, if we apply an exponent of 7 to this number, we will get:

z^7 = ( 5*e^(-i*0.64))^7

z^7 = 5^7*e^(-i*7*0.64) = 78,125*e^(-i*4.48)

Apply the distributive property to factor out the greatest common factor.

podryga [215]

Answer:

12 + 20 = 4(3 + 5)

Step-by-step explanation:

The distributive property is ab + ac = a(b + c), where

a is the greatest common factor of the two terms ab and ac

Let us solve the question

∵ 12 = 1 × 12, 2 × 6, 3 × 4

∴ The factors of 12 are 1, 2, 3, 4, 6, 12

∵ 20 = 1 × 20, 2 × 10, 4 × 5

∴ The factors of 20 are 1, 2, 4, 5, 10, 20

→ Find their common factors

∵ The common factors of 12 and 20 are 1, 2, 4

∴ The greatest common factor of 12 and 20 is 4

∵ 12 ÷ 4 = 3

∵ 20 ÷ 4 = 5

∴ 12 + 20 = 4 × 3 + 4 × 5

→ Take 4 as a common factor

∴ 12 + 20 = 4(3 + 5)

Answer:

40 children went on the cruise.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of adults on the cruise

y is the number of children on the cruise.

57 tickets were sold:

This means that $x + y = 57$ , and since we want the number of children y, $x = 57 - y$

Each adult had to pay $22 for the cruise and each child had to pay $10. The company's total receipts were $774.

This means that:

$22x + 10y = 774$

Since $x = 57 - y$

$22(57 - y) + 10y = 774$

$1254 - 22y + 10y = 774$

$12y = 480$

$y = \frac{480}{12}$

$y = 40$

40 children went on the cruise.

jenny won the ping pong championship eight more times than gerardo. they have won a combined total of 32 championship

Lena [83]

X + x +8 = 32
2x + 8 = 32
2x = 24
x = 12
So gerardo has won 12 and jenny has won 20
