Answer:
Step-by-step explanation:
<u>Given</u>
- z₁ = 9 + 9√3i
- z₂ = 2 + √3i
<u>To find</u>
<u>Solution</u>
- z₂ - z₁ =
- 2 + √3i - (9 + 9√3i) =
- 2 - 9 + √3i - 9√3i =
- -7 + (1 - 9)√3i =
- -7 - 8√3i
Second option is correct (you have selected it right)
Step-by-step explanation:
Option d is not a polynomial
<u><em>Commutative:</em></u>
93 + (68 + 7) ⇒ (68 + 7) + 93
<u><em>Associative:</em></u>
93 + (68 + 7) ⇒ (93 + 68) + 7
<u><em>Identity:</em></u>
93 + (68 + 7) + 0 ⇒ 93 + (68 + 7)
Answer:
a. A customer earns 1 free night per 10 nights stayed.
Step-by-step explanation:
The missing function is:
f(x) = x/10
The missing options are:
<em>
a. A customer earns 1 free night per 10 nights stayed. </em>
<em>
b. A customer starts with 1 free night and then earns another free night after every 10 nights stayed.
</em>
<em>
c.A customer earns x – 10 free nights for every 10 nights stayed. </em>
<em>
d. A customer earns 10 free nights after x number of nights stayed.
</em>
The function means that after a customer stayed 10 nights, a free night is earned. That is, replacing x = 10 into the function, we get:
f(10) = 10/10 = 1
which means 10 nights are equivalent to 1 free night.
Answer:
48 units sq
Step-by-step explanation:
Find the area of each square/rectangle
2x2
2x5
2x5
2x5
2x2
