Answer:
- We would use the explicit formula
Step-by-step explanation:
<u>The recursive formula is good to find the next term, example:</u>
<u>You would need the explicit formula to find any term, example:</u>
Answer: One side could be 18 and the other side will be 33.
Step-by-step explanation:
- Side #1 = 18
- Side #2 = 2x - 3
- Side #3 = x
<u>One way of setting up the inequality is: Side #2 + Side #3 > Side #1</u>
<u />
<u>Another way of setting up the inequality is: Side #1 + Side #3 > Side #2</u>
<u />
<u />
<u>Final way of setting up the inequality is: Side #1 + Side #2 > Side #3</u>

<em>Therefore, we have the range for our value of x, which is between 7 and 21. Any possible value between works. Negative measurements are rejected. One of the sides would equal the x-value, while the other side would equal the value of 2x-3.</em>
A.
= (x + 2)^2 - 4 - 11
= (x + 2)^2 - 15
B. vertex is at ( -2, -15) which is a minimum because the coefficient of x^2 is positive.
C. The axis of symmetry is a vertical line passing through the vertex It is
x = -2.
we will check each options
option-A:
The modulus represents the distance between the complex number and the origin
we know that modulus is a kind of distance
For example: if we have to find modulus of x+iy
we get

that is also distance between (0,0) and (x,y)
so, this is TRUE
option-B:

It is also similar to Pythagoras theorem
so, this is also TRUE
option-C:
we got modulus formula

we know that value of sqrt can never be negative because it will always result in positive value
so, this is FALSE
option-D:

It is also similar to absolute value
so, this is TRUE
