Hello!
f(x) = 3x + 2
Since you are provided with f(5), we will replace every "x" in the equation with the number 5.
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17

1. Contaminated water is subjected to a cleaning process. The concentration of the pollutants is initially 5 mg per liter of water. If the cleaning process can reduce the pollutant by 10% each hour, define a function that can represent the concentration of pollutants in the water in terms of the number of hours that the cleaning process has taken place.
Answer:
[tex]C(t)=5\cdot(0.9)^t[/tex]
Step-by-step explanation:
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The concentration of the pollutants starts at Co=5 mg/lt. We also know the pollutant reduces its concentration by 10% each hour. This gives us a value of r = 10% / 100 = 0.1
Substituting into the general equation:
[tex]C(t)=5\cdot(1-0.1)^t[/tex]
Operating:
[tex]\boxed{C(t)=5\cdot(0.9)^t}[/tex]
y(n) = 5(0.9)ⁿ
To answer this, we will make use of the exponential decaying function which is given by;y(n) = a(1 - b)ⁿ
where;
y is the final amount at time n,
a is the original amount
b is the decay factor
x is the amount of time that has passed.
We are told that the initial concentration of the pollutants is 5 mg/LThus;
a = 5 mg/L.
We are told that the pollutant reduces its concentration by 10% each hour. Thus; b= 10%
b = 0.1
Therefore Plugging in the relevant values into y(n) = a(1 - b)ⁿ, we have;y(n) = 5(1 - 0.1)ⁿ
y(n) = 5(0.9)ⁿ

How do you build a triangle if you are given 3 numbers like 3,4,5. Provide an example besides 3,4,5 or a non-example.
Pattern:
Example:
Answer:
3, 4, and 5 make a right triangle (Pythagorean triple). 3 and 4 are the legs, 5 is the hypotenuse. Another example is 9, 12, 15, with 9 & 12 as the legs and 15 as the hypotenuse on a right triangle.
Step-by-step explanation:
Pythagorean triples (measurements are whole numbers) are always in a 3:4:5 ratio; the longest side is always hypotenuse; the right angle is always opposite of the hypotenuse; the legs will be perpendicular (making right angle)

One factor of the polynomial 2x3 -3x2 – 3x + 2 is (x - 2), which expression represents the other factor, or factors, of the polynomial?
A. (2x + 1)(x - 1)
B (2.x2 - x+ 1)
C (2x2 + 1)
D. (2x - 1)(x+1)
Answer:
It's actually D (2x - 1)(x+1)
Step-by-step explanation:
The required factor of the polynomial 2x³ - 3x² - 3x + 2 is (2x - 1)(x + 1).
Given that,
One factor of the polynomial 2x3 -3x2 – 3x + 2 is (x - 2), which expression represents the other factor, or factors, of the polynomial is to be determined.
What are the factors?
factors can be defined by splitting the value into multipliable values.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
x - 2 is one factor of 2x³ - 3x² - 3x + 2 than
( 2x³ - 3x² - 3x + 2 ) / x - 2 = 2x² + x -1 = (2x - 1)(x + 1)
Thus, the required factor of the polynomial 2x³ - 3x² - 3x + 2 is (2x - 1)(x + 1).

Answer:
If Kasey bought one drink, she will be able to buy 6 food items
Step-by-step explanation:
We know Kasey has $8 and if she bought one drink, she will have $7.5
We have to find how many food items she can buy (all of them are $1.25)
$7.5/1.25= 6 food items
If Kasey bought one drink, she will be able to buy 6 food items
Hope this helps!
Answer:
6 items
Step-by-step explanation:
8.00 - 0.50 = 7.50
She has $7.50 to spend on food after buying one drink
7.50 ÷ 1.25 = number of food items she can buy
7.50 ÷ 1.25 = 6

Answer:
Undefined
Step-by-step explanation:
The x value is always 5 so the slope is undefined
Answer:
The slope of the line is undefined.
Step-by-step explanation:
To solve this problem, we should use the formula for slope, which is given below:
m = slope = (y2-y1)/(x2-x1)
If we plug in two of the points that are given in the table, we get:
m = slope = (6-3)/(5-5)
If we perform the subtraction in the parentheses in both the numerator and the denominator, we get:
slope = 3/0
Since we cannot divide by 0, this means the slope is undefined.

Step-by-step explanation:
Follow PEMDAS:
(7/2-1/3) * (-2)^2 +1/2
P: parenthesis... 7/2 - 1/3 is 19/6
then you do E: exponents... (-2)^2 is basically -2 * -2 which a negative multiplied by a negative is a positive so its 4.
19/6 * 4+1/2

If ΔABC = ΔDEF, angle m∠A = 50, and angle m∠E = 30, what is angle m∠C?
When you indicate triangle congruency, the order of the letters matter. As you see these statements, look at how the side length names correspond to how the letters are written in its order, ΔABC ≅ ΔDEF. (By the way, triangles aren't equal with an = sign. It's a ≅ congruency sign.)
AB is congruent or the same length as DE.
BC is congruent or the same length as EF.
AC is congruent or the same length as DF.
In the same way, all of the angles in the corresponding order are ALSO congruent. By the way, we say that angles are congruent and angle MEASURES (like 30 degrees) are equal.
m∠A = m∠D
m∠B = m∠E
m∠C = m∠F
In the same way, we can try to find m∠C, or measure C!
1. Let's find the missing angle!
So, we know that m∠A is 50 degrees and m∠E is 30 degrees. Since we know that m∠E = m∠B because of the order of the triangles, now we know two of the angles in triangle ABC.
m∠A = 50 degrees
m∠B = 30 degrees
m∠C = 180 degrees - (50 + 30) = 100 degrees
(We minus from 180 degrees because 180 degrees is the sum of the angles in a triangle!)
And that's it! If you have any questions, please feel free to ask questions. I'm not here to judge, and I'm only here to help. Again, ask questions if you need help. It's crucial that you know the basics of geometry!
You notice a hot air balloon descending. The elevation h
(in feet) of the balloon is modeled by the function h(x)=−8x+360,
where x
is the time (in seconds) since you first noticed the hot air balloon.
Graph the function and specify its domain and range. Then interpret the slope and intercepts of the graph.
Answer:
the domain is 0 x 45 and the range is 0 h 360. The slope is -8, so the change in the height of the ballon is -8 feet per second. The h-intercept is 360, so the height of the ballon when the first noticed it was 360 feet. The x-intercept is 45, so the time it took the hot air balloon to reach the ground was 45 seconds.
Step-by-step explanation:
The descending balloon is an illustration of a linear function.
The balloon spent 45 seconds in air The balloon was at a height of 360 feet when you noticed it.The balloon descends 8 feet per seconds.[tex]\mathbf{Domain=[0,45]}[/tex].[tex]\mathbf{Range=[0,360]}[/tex]The function is given as:
[tex]\mathbf{h(x) = -8x + 360}[/tex]
See attachment for the graph of h(x)
From the graph, we have the following observations
The y value ranges from 0 to 360The x value ranges from 0 to 45The function crosses the graph at x = 45 and y = 350The above highlights mean that:
[tex]\mathbf{Domain=[0,45]}[/tex][tex]\mathbf{Range=[0,360]}[/tex][tex]\mathbf{x-intercept = 45}[/tex][tex]\mathbf{y-intercept = 360}[/tex]The x intercept means that:
The balloon spent 45 seconds in air
The y-intercept means that:
The balloon was at a height of 360 feet when you noticed it.
A linear function is represented as:
[tex]\mathbf{y = mx + c}[/tex]
Where:
m represents the slope
By comparison with [tex]\mathbf{h(x) = -8x + 360}[/tex]
[tex]\mathbf{m = -8}[/tex]
The above value of slope means that:
The balloon descends 8 feet per seconds
