An empty shipping box weighs 250 grams. The box is then filled with t-shirts. Each t-shirt weighs 132.5 grams.
The equation W=250+132.5t represents the relationship between the quantities in this situation, where W is the weight, in grams, of the filled box and is the number of shirts in the box.
If the company ships 100 t-shirts in a box, how much will the box weigh?
________ grams
========================================================
Explanation:
t = number of t-shirts
t = 100 shirts are in the box
Plug this into the equation and simplify to find W
W = 250+132.5t
W = 250+132.5(100)
W = 250+13250
W = 13500
The box weighs 13500 grams
This is equivalent to 13500/1000 = 13.5 kg

Find a polynomial function of least degree having only real coefficients, a leading coefficient of 1, and zeros of 2 and 3+ i
The polynomial function of least degree with only real coefficients is y = x³ - 8 · x² + 22 · x - 20.
What is the polynomial function of least degree with real coefficients?
The statement indicates that the polynomial has a leading coefficient of 1 and zeros of 2 and 3 + i. By algebra of quadratic equations, equations with real coefficients with complex roots are α + i β and α - i β. Then, all the roots of the polynomial function of least degree are 2, 3 + i and 3 - i. The complete expression is shown below:
y = 1 · (x - 2) · (x - 3 - i) · (x - 3 + i)
y = (x - 2) · [x² - 3 · x - i · x - 3 · x + i · x + (3 + i) · (3 - i)]
y = (x - 2) · (x² - 6 · x + 9 - i²)
y = (x - 2) · (x² - 6 · x + 10)
y = x³ - 6 · x² + 10 · x - 2 · x² + 12 · x - 20
y = x³ - 8 · x² + 22 · x - 20

In your own words, describe what transformations are possible in a linear function and what in the equation causes these movements.
The transformations that is possible in a linear function is: g(x) = (x - 3)².
What in the equation causes these movements?if the function of the g (x) is known to be the original function, then one can say that:
g(x) = (x - 3)²
= g(x) = x²
This is one that is shifted by 3 unit to the right because in the above, one need to substitute x for x - 3.
Hence , it functional graph can be said to be a parabola with a vertices that is known to be opening at (3,0)

it is always the same. the slope is (y coordinate change / x coordinate change) when going from one point on the line to another.
the direction itself does not matter, but it is important to use the same direction for the x and the y comparison.
I prefer to go from left to right, so let's go from

x changes by +5 (from -3 to 2).
y changes by -8 (from 4 to -4).

ALGAE A scientist has a fish tank in the shape of a rectangular prism. The tank is 18 inches high, 14 inches wide, and 30 inches long. After one month, the scientist found that the sides and bottom of his fish tank were covered with algae. The scientist wants to run tests on the algae to help determine why it started to grow. How much algae is there for the scientist to test?
the algae that is present with the scientist to research upon covers a surface area of 2004 inches² in the rectangular prism.
The dimensions of the rectangular prism is given by:
Height = h = 18 inches
Width = w = 14 inches
Length = l = 30 inches
Now, we have to calculate the surface area of the tank excluding the top of the tank to find out how much algae has been present there for the scientist to test.
So, the formula for surface area will become:
A = 2(w l + h l + h w) - l w ( as the top has to be excluded)
Now substituting the values of l, w and h, we get that:
A = 2 [ (14) (30) + (18) (30) + (18) (14) ] - (30) (14) inches²
A = 2 [ 420 + 540 + 252 ] - 420 inches²
A = 2 [ 1212 ] - 420 inches²
A = 2424 - 420 inches²
A = 2004 inches²
Therefore, we get that, the algae that is present with the scientist to research upon covers a surface area of 2004 inches² in the rectangular prism.

Step-by-step explanation:
Piecewise functions have multiple pieces of curves/lines where each piece corresponds to its definition over an interval.
Given piecewise function:
[tex]f(x)=\begin{cases} \begin{aligned}-2x-4 & \;\;\textsf {if }\;x < 0\\3x & \;\;\textsf {if }\;x\geq 0\\\end{aligned}\end{cases}[/tex]
Therefore, the function has two definitions:
[tex]\textsf{$f(x)=-2x-4$ when $x$ is less than zero}.[/tex][tex]\textsf{$f(x)=3x$ when $x$ is more than or equal to zero}.[/tex]When graphing piecewise functions:
Use an open circle where the value of x is not included in the interval.Use a closed circle where the value of x is included in the interval.Use an arrow to show that the function continues indefinitely.First piece of the function
Substitute zero into the first function:
[tex]\implies f(0)=-2(0)-4=-4[/tex]
Place an open circle at point (0, -4).
To help graph the line, find another point on the line by inputting another value of x that is less than zero into the same function:
[tex]\implies f(-2)=-2(-2)-4=0[/tex]
Place point (-2, 0) and draw a straight line from the open circle at (0, -4) through (-2, 0). Add an arrow at the other endpoint to show it continues indefinitely as x → -∞.
Second piece of the function
Substitute zero into the second function:
[tex]\implies f(0)=3(0)=0[/tex]
Place an closed circle at point (0, 0).
Again, to help graph the line, find another point on the line by inputting another value of x that is more than zero into the same function:
[tex]\implies f(2)=3(2)=6[/tex]
Place point (2, 6) and draw a straight line from the closed circle at (0, 0) through (2, 6). Add an arrow at the other endpoint to show it continues indefinitely as x → ∞.
See attached for graph.
To find the given functions, decide which function to use based on the given value of x, then solve.
f(0) means to find the value of the function when x = 0.
Therefore, input x = 0 into the second function as x ≥ 0.
[tex]\implies f(0)=3(0)=0[/tex]
f(-2) means to find the value of the function when x = -2.
Therefore, input x = -2 into the first function as x < 0.
[tex]\implies f(-2)=-2(-2)-4=0[/tex]
f(5) means to find the value of the function when x = 5.
Therefore, input x = 5 into the second function as x ≥ 0.
[tex]\implies f(5)=3(5)=15[/tex]
f(-10) means to find the value of the function when x = -10.
Therefore, input x = -10 into the first function as x < 0.
[tex]\implies f(-10)=-2(-10)-4=16[/tex]

Gabriella's school is selling tickets to a choral performance. On the first day of ticket sales the
school sold 14 senior citizen tickets and 14 child tickets for a total of $252. The school took in
$154 on the second day by selling 9 senior citizen tickets and 7 child tiekets. Find the price of a
senior citizen ticket and the price of a child ticket.
The ticket price of
A Senior citizen = $14
A Child = $4
First day of ticket sales :
Senior citizen tickets (s) = 14
Child tickets (c) = 14
Total price of both tickets = $252
14s + 14c = 252 eq. (1)
Second day of ticket sales :
Senior citizen tickets (s) = 9
Child tickets (c) = 7
Total price of both tickets = $154
9s + 7c = 154 eq. (2)
Multiplying equation 2 with 2, we get
18s + 14c = 308 eq. (3)
Now, we will subtract eq. (1) from eq. (3)
18s + 14c = 308 eq. (3)
-14s - 14c = -252 eq. (1)
____________________
4s = 56
s = 56/4
s = 14
We get the ticket price of one senior citizen which is 14 Dollars.
Now, we will put s = 14 in eq. 2,
So, 9s + 7c = 154
(9×14) + 7c = 154
7c = 154 - 126
c = 28 / 7
c = 4
Ticket price of one child is 4 Dollars.
Hence, the ticket price of a senior citizen and a child is $14 and $4, respectively.
