The expression that models Tyrell's net proceeds algebraically is d-(1.03ns + 15) .
In the question ,
it is given that ,
Tyrell bought n shares for s dollars
So the price Tyrell paid for shares = $ ns .
Tyrell also paid 3% commission ,
so the total cost price Tyrell paid for shares = price of share + commission
total cost price = ns + 3% of ns
= ns + 0.03ns ....as 3% = 0.03
= 1.03ns ...(i)
Tyrell sold the stocks for d dollars .
Tyrell also paid the flat fee of $15 .
So, the selling price for stocks = d-15 ......(ii)
The Tyrell's Net Proceeds can be calculated using the formula
Net Proceeds = Selling Price - Cost price
Substituting the values of selling price and cost price from (i) and (ii) ,
we get ,
Net Proceeds = (d-15)-(1.03ns)
= d-15-1.03ns
= d-(1.03ns + 15)
Therefore , the expression that models Tyrell's net proceeds algebraically is d-(1.03ns + 15) .
The given question is incomplete , the complete question is
Tyrell bought n number of shares for s dollars and paid a 3% commission. He sold the stock for d dollars and paid a flat fee of $15. Write an expression to model Tyrell’s net proceeds algebraically.

When 12 is subtracted from the square of a number, the result is 4 times the number. Find the negative solution.
When 12 is subtracted from the square of a number and the result is 4 times the number, then the negative solution is -2
Consider the number as x
Square of the number = [tex]x^{2}[/tex]
12 subtracted from the square of a number = [tex]x^{2} -12[/tex]
4 times the number = 4x
Then the equation will be [tex]x^{2} -12=4x[/tex]
Rearrange the terms and it will become a quadratic equation
[tex]x^{2} -4x-12=0[/tex]
Split the middle term and solve the equation
[tex]x^{2} +2x-6x-12=0[/tex]
Take common terms
x(x+2)-6(x+2) = 0
Take common term outside
(x-6)(x+2) = 0
Therefore
x = 6, -2
The negative solution is -2
Hence, when 12 is subtracted from the square of a number and the result is 4 times the number, then the negative solution is -2

If the vertical component of velocity for a projectile is 7.3 meters/second, find its hang time. a. 1.5 seconds b. 2.5 seconds c. 5.6 seconds d. 6.7 seconds e. 7.1 seconds
The hang time is calculated to be a. 1.5 seconds if the vertical component of velocity for the projectile is 7.3 meters/second.
The formula for the height of the projectile can be used to calculate the hang time as follows;
h = ut - 0.5at²
here;
h is the height of the projectile
u is the velocity = 7.3 m/s
a is the acceleration due to gravity
The standard value of acceleration due to gravity is equal to 9.81 m/s²
The height will be zero both the times when t=0 and when the journey has been completed
Now adding these values to the formula;
h = ut - 0.5at²
0 = 7.3t - 0.5(9.81)t²
Solving for t;
4.905t² = 7.3t
4.905t² / t = 7.3
4.905t = 7.3
t = 7.3 / 4.905
t = 1.49 ≈ 1.5
Therefore; the hang time is calculated to be 1.5 seconds.

Kali just started a new sales floor job to save for college. She earns $15.75 per hour plus a flat fee of $50 per week. She wants to earn between $200 and $400 per week. The following inequality represents her earning potential: 200 ≤ 15.75x + 50 ≤ 400 Solve the inequality.
The solution set of the given inequality is:
9.52 ≤ x ≤ 22.22
Or [9.52, 22.22] if we write this as an interval.
How to solve the inequality?Here we have the inequality:
200 ≤ 15.75x + 50 ≤ 400
Which represents Kali's earning potential.
To solve the inequality we need to isolate the variable in the middle, if we subtract 50 in the 3 sides we get:
200 - 50 ≤ 15.75x + 50 - 50 ≤ 400 - 50
150 ≤ 15.75x ≤ 350
Now we need to divide both all by 15.75, so we get:
150/15.75 ≤ 15.75x/15.75 ≤ 350/15.75
9.52 ≤ x ≤ 22.22
This is the solution of the inequality, the solution set written as an interval will be [9.52, 22.22]
