Answer:
A

and
D

Step-by-step explanation:
Because if you simplify the equation theb you get 8x+4 therefore D is equivalent to it. A is also equal to D which make it equivalent to the equation as well.
Answer:
59049 digits
Step-by-step explanation:
Given
Digits = 0 to 9
Required
Determine number of 5 digit pins that must not contain 0
There are 10 digits.
Since the pin must not contain 0, there are 9 digits left to select from.
The question didn't state that a digit can not be repeated, so I'll assume that repetition of digit is allowed.
The 1st digit of the 5 could be any of the 9 digits
The 2nd could be any of the 9 digits
The 3rd could be any of the 9 digits
The 4th could be any of the 9 digits
The 5th could be any of the 9 digits
Hence, number of selection is calculated as this:
Selection = 9 * 9 * 9 * 9 * 9
Selection = 59049
(x + (3 + 5i))*(x + (3+5i))
= x^2 + x(3+5i) + x(3+5i) + (3 + 5i)^2
= x^2 + 2x(3+5i) + 9 + 6(5i) + 25i^2
= x^2 + 6x +10xi + 9 + 30i - 25
= x^2 + 6x + 10xi + 30i - 16
Answer:
1. quadratic
2. quadratic
3. linear
4. quadratic
Step-by-step explanation:
In the picture attached, the scatter plots are shown.
The differences between these correlations are:
- linear
: makes a straight line
- quadratic: makes a ∩ or ∪
- exponential: rises or falls quickly in one direction
In plot 1, 2 and 4, we can see that y-values decrease at first and then they increase. This is a feature of quadratic correlation
In plot 3, we can see that y-values increase uniformly as x-values increase.This is a feature of linear correlation
