All of these make use of the expansion
   (a + b)² = a² + 2ab + b²
You would do well to memorize this "formula." Of course, it also helps to be able to double (or halve) a number, and to know the squares of small integers.

1.
   x² +2x +1
   x² -6x +9
   x² +12x +36
   x² -0.4x +0.04
   4x² +28x +49
   9x² +30x +25

2.
   (x + 4)²
   (x + 3)²
   (x - 9)²
   (x - 5)²

3. (12/2)² = 36

4. ±2√49 = ±14

Suppose there is a 3.1 temperature drop for every thousand feet that an airplane climbs
SSSSS [86.1K]

Answer:

34.1 degrees

Step-by-step explanation:

given that the temperature drops 3.1 degrees for every thousand feet of elevation.

for an altitude of 11,000 feet (i.e 11 x 1000 feet), the temperature (compared to ground level) would drop,

= 3.1 deg / 1000-foot   x   11,000 feet

= 34.1 degrees

Question 5. Bob Orleans invested $3,000 and borrowed $3,000 to purchase shares in Verizon Communications. At the time of his inv
Tasya [4]

The number of shares could he buy is 63.19 and 126.38. Then the profit gained by Bob is $764.68.

<h3>What is the profit gained by Bob?</h3>

Bob Orleans invested $3,000 and borrowed $3,000 to purchase shares in Verizon Communications.

At the time of his investment, Verizon was selling for $47 a share.

If Bob paid a $30 commission, then the number of shares could he buy if he used only his own money and did not use margin.

\rightarrow  \dfrac{3000- 30}{47}\\\\\rightarrow  \dfrac{2970}{47}\\\\\rightarrow  63.19

If Bob paid a $60 commission, then the number of shares could he buy if he used his $3,000 and borrowed $3,000 on margin to buy Verizon stock will be

\rightarrow \dfrac{6000 - 60 }{47}\\\\\rightarrow  \dfrac{5940}{47}\\\\\rightarrow 126.38

Assume Bob did use margin and paid a $60 total commission to buy his Verizon stock. Also, assume he paid another $60 to sell his stock and sold the stock for $54 a share. Then the profit will be

\rightarrow (126.38 \times 54 - 60)  - (6000)\\\\\rightarrow (6824.68 - 60) - 6000\\\\\rightarrow  6764.68 - 6000\\\\\rightarrow \$764.68

White raven [17]

Answer:

OPTION C:   - 5

Step-by-step explanation:

Domain of the function is the set of all possible values that the variable can take.

Let us say the function f(x) = x.

Then the set of all possible values that 'x' can take is called as Domain of the function.

The same definition applies to relation as well.

In the given relation Domain = {-5, 4, 4, 3}

Hence, OPTION C = - 5 is the correct answer,
