Answer:
Step-by-step explanation:
(Please show work and No links) If you bought 28 shares of stock at $30/sh and sold them at $25/sh. And How much did you net after selling the shares? Was it a profit or a loss?
Let C be the total cost;
[tex]c = 28 \times 30 = 840[/tex]
Let R be the total revenue;
[tex]r = 28 \times 25 = 700[/tex]
Let P be the net profit;
[tex]p = r - c[/tex]
[tex]p = 700 - 840 = - 140[/tex]
There was a 140$ net loss.

Answer:
1 (the answer will always be 1)
Step-by-step explanation:
Let's forget about the absolute value signs for a second and just look at what's inside
[tex]\frac{x+y}{-x-y}[/tex]
This can be rewritten as
[tex]-\frac{x+y}{x+y}[/tex]
When you have the same numerator and denominator, it will always come out to 1, so we can just say that this is saying
[tex]-\frac{x+y}{x+y} = -1[/tex]
Now, back to the absolute value signs
This comes out to negative 1, but the absolute value signs means to always change the negative to a positive (but if it's a positive, it stays positive!)
So that means:
[tex]|-1| = 1[/tex]
and 1 is your answer

A company wants to decrease their
energy use by 15%. If their electric
bill is currently $2,100 a month,
what will their bill be if they are
successful? Give your answer
accurate to at least the nearest
dollar.
15% decrease means the bill would be 85% of the original bill ( 100% -15% = 85%)
multiply the current bill by 85%
2100 x 0.85 = 1.785
the bill would be $1,785

Nine more than the product of a number and eight equals four
Answer:
Step-by-step explanation:
Let the number = 'x'
Product of number and eight ⇒ 8*x = 8x
Nine more than the product of 8x ⇒add 9 to 8x
8x + 9 = 4
8x = 4 - 9
8x = -5
x = -5/8

1/2x +12 = 21
1/2x = 9
x = 18
9.
28 - 3x - 4 = 2x + 12 + x
24 - 3x = 3x + 12
24 - 6x = 12
-6x = -12
x = 2
10.
3x - 18 + 6 = 5x - 6
3x - 12 = 5x - 6
-2x - 12 = -6
-2x = 6
x = -3

Which of the following polynomials has solutions that are not real numbers?
A
x2 - 6x +3
B
x2 + 4x +3
-*? - 9x - 10
x? + 2x +3
Answer:
Option 4 is correct.
Step-by-step explanation:
To find: Polynomial whose solution are not real numbers.
Given Polynomials are Quadratic Polynomial.
So, we can check if solution of quadratic polynomial by find & checking value of discriminant.
Standard form of Quadratic polynomial is given by
ax² + bx + c
then Discriminant, D = b² - 4ac
If, D > 0 ⇒ Solutions are distinct real numbers
if, D = 0 ⇒ Solutions are equal real numbers
if, D < 0 ⇒ Solutions are not real numbers (They are complex conjugates)
Option A:
By comparing with standard form
a = 1 , b = -6 , c = 3
D = (-6)² - 4 × 1 × 3 = 36 - 12 = 24 > 0
Thus, Solutions are Real numbers.
Option B:
By comparing with standard form
a = 1 , b = 4 , c = 3
D = (4)² - 4 × 1 × 3 = 16 - 12 = 4 > 0
Thus, Solutions are Real numbers.
Option C:
By comparing with standard form
a = -1 , b = -9 , c =-10
D = (-9)² - 4 × (-1) × (-10) = 81 - 40 = 41 > 0
Thus, Solutions are Real numbers.
Option D:
By comparing with standard form
a = 1 , b = 2 , c = 3
D = (2)² - 4 × 1 × 3 = 4 - 12 = -8 < 0
Thus, Solutions are not Real numbers.
Therefore, Option 4 is correct.

a. Randomly choosing an oatmeal cookie, eating it, and then choosing a peanut butter
cookie from a container of cookies.
b. Drawing the name "Sally" from a hat and replacing it, and then drawing the name
"Malcolm" from the hat.
The fact that one chooses an oatmeal cookie, eating it and then choosing a peanut butter cookie from a container of cookies is an independent event.
What is a dependent event?It should be noted that dependent events influence the probability of the other events.
In this case, the fact that one chooses an oatmeal cookie, eating it, and then choosing a peanut butter cookie from a container of cookies is an independent event.
On the other hand, drawing the name "Sally" from a hat and replacing it, and then drawing the name "Malcolm" from the hat is a dependent event.

R (-3,1) and S (-1,3) are points on a circle. If RS is a diameter, find the equation of the circle.
Answer:
[tex]\sf (x+2)^2+(y-2)^2=2[/tex]
Step-by-step explanation:
If RS is the diameter of the circle, then the midpoint of RS will be the center of the circle.
[tex]\sf midpoint=\left(\dfrac{x_s-x_r}{2}+x_r,\dfrac{y_s-y_r}{2}+y_r \right)[/tex]
[tex]\sf =\left(\dfrac{-1-(-3)}{2}+(-3),\dfrac{3-1}{2}+1 \right)[/tex]
[tex]\sf =(-2, 2)[/tex]
Equation of a circle: [tex]\sf (x-h)^2+(y-k)^2=r^2[/tex]
(where (h, k) is the center and r is the radius)
Substituting found center (-2, 2) into the equation of a circle:
[tex]\sf \implies (x-(-2))^2+(y-2)^2=r^2[/tex]
[tex]\sf \implies (x+2)^2+(y-2)^2=r^2[/tex]
To find [tex]\sf r^2[/tex], simply substitute one of the points into the equation and solve:
[tex]\sf \implies (-3+2)^2+(1-2)^2=r^2[/tex]
[tex]\sf \implies 1+1=r^2[/tex]
[tex]\sf \implies r^2=2[/tex]
Therefore, the equation of the circle is:
[tex]\sf (x+2)^2+(y-2)^2=2[/tex]

[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]
The given function has Amplitude of 3, and by seeing it we can conclude that it's a sine function.
Therefore, we can conclude that the required Answer is ~
[tex]\qquad \sf \dashrightarrow \:c. \: f(t) = 3 \sin(4t) [/tex]
The sinusoidal function is represented as y = 3 sin 4t. Then the correct option is C.
What is a sinusoidal Function?It is a function that repeats itself in a particular time interval.
The sine function is given as
y = A sin (wt + Ф)
where A is the amplitude, w frequency, and Ф is the phase difference.
From the graph, the value of the amplitude will be 3, the frequency will be 4, and the phase difference will be 0. Then the equation will be
y = 3 sin4t
