What is the asymptote of the graph of an exponential growth or exponential decay function? Explain your reasoning.
Answers
Let's consider an exponential decay function.
As an example, let's look at [tex]f(\text{x}) = 100(0.5)^{\text{x}}[/tex]
Here is a table of selected values:
[tex]\begin{array}{|c|c|} \cline{1-2}\text{x} & \text{f(x)}\\\cline{1-2}0 & 100\\\cline{1-2}1 & 50\\\cline{1-2}2 & 25\\\cline{1-2}3 & 12.5\\\cline{1-2}4 & 6.25\\\cline{1-2}5 & 3.125\\\cline{1-2}6 & 1.5625\\\cline{1-2}\end{array}[/tex]
As x gets bigger, y = f(x) is slowly approaching y = 0. It will never get to this exact value because we keep taking half of the previous y value (eg: we go from y = 25 to y = 12.5); there's no way to arrive at zero through this continuous halving process. If x/2 = 0, then x itself must be 0. But we started off with a nonzero value.
Visually, the curve is slowly approaching the x-axis. We say that the horizontal asymptote is y = 0 which is directly overlapping the x-axis. Think of the asymptote as an electric fence you can get closer to but not actually touch.
See the graph below. I used Desmos to create the graph.

Charles is in charge of cooking broccoli and zucchini for a large group. He has to spend all $20.10 he has and can carry 11 pounds of veggies. Zucchini costs $1.60 per pound and broccoli costs $2.10 per pound. How many pounds each of zucchini and broccoli can Charles get so that he spends all $20.10 and gets 11 pounds of veggies? Let x represent the number of pounds of zucchini and y represent the number of pounds of broccoli. Show ALL work!
Answers
Answer:
Total equation: X + Y = 11 pounds
Cost equation: 1.60X + 2.10Y = 20.10
Number of Pounds of Zucchini = 6
Number of Pounds of Broccoli = 5
Step-by-step explanation:
You get the equations by just pulling the information from the text.
We then take the total equation and rearrange it to solve for one of our values. I will be using X
X + Y = 11 so first subtract X from both sides to get
Y = 11 - X so now we know what Y equals
next take the cost equation and input X in wherever it shows up so
1.60 (X) + 2.10 (11 - X) = 20.10
now distribute 2.10 to the values in the parathesis to get
1.60X + 23.1 - 2.10X = 20.10
now combine like terms
-0.5X + 23.1 = 20.10
now subtract 23.1 from both sides
-0.5X = -3
now divide both sides by -0.5
X = 6
so now we know that he both 6 pounds of zucchini now plug that into the total equation
6 + Y = 11
subtract 6 from both sides
Y = 5

Which of the following inequalities matches the graph? (1 point)
graph of an inequality with a solid vertical line through the point 5, 0 and shading to the left of the line
x ≤ 5
x ≥ 5
y ≤ 5
y ≥ 5
Answers
Answer: The inequality that matches the graph is x ≤ 5. This is because the graph has a solid vertical line at x = 5 and the shading is to the left of the line. This indicates that all values of x that are less than or equal to 5 satisfy the inequality.
The inequality x ≥ 5 would not match the graph because the shading would be to the right of the line. The inequalities y ≤ 5 and y ≥ 5 do not match the graph because they are not in the correct form. Inequalities involving y have a graph with a horizontal line, not a vertical line.

A student earned the scores in the data set in one course. {78, 64, 74, 92, 67} What is the mean of the scores?
Answers
Answer: The mean is 75
Step-by-step explanation:
- You add the scores in the data:
78+64+74+92+67 = 375
- Then divide by the number of scores in the data:
there are 5 scores in the data,
1) 78
2) 64
3) 74
4) 92
5) 67
- So:
375/5 = 75 <--- mean
To calculate mean or average from a data set, add all the data points together and then divide by the number of points you added together.
In this case,
78+64+74+92+67= 375/5= 75

Answer:
16.449 = 16.4
9.84 = 9.8
by estimating = 26.2
Answer:
16.5+9.8=26.3
Step-by-step explanation:
The equation is 16.449+9.84. We need to add these together after we round them to the nearest tenth. Well with decimals it goes ones, tenths, hundreths. So The second number past the decimal on the right side, is the one that we are rounding. If the number is greater than 5 then we move the number to the next tenth value.If its less than f5 we do the complete opposite.
16.449 is going to be rounded to be 16.5.
9.84 is going to be rounded to be 9.8
Now that our numbers are rounded we can add them.
16.5+9.8=26.3
I hope this helps!!!

The model of the exponential functions show that
23: table 1 is a decay with a rate of 50%24. tables 2 is a growth with a rate of 10%How to write exponential function to model the data in each tableConsidering the given problem, f(x) = a(b)^x
the starting = a
the base = b
the exponents = x
23. Table 1
At x = 0
f(x) = a(b)^x
(b)^0 = 1
solving for a
4 = a * (b)^0
4 = a
At x = 1
f(x) = a(b)^x
(b)^1 = b
substituting known variables
2 = 4(b)^1
b = 2/4
b = 0.5
for decreasing rate, b = 1 - 0.5 = 0.5
rate, r = 50%
24. Table 2
At x = 0
f(x) = a(b)^x
(b)^0 = 1
solving for a
100 = a * (b)^0
100 = a
At x = 1
f(x) = a(b)^x
(b)^1 = b
substituting known variables
110 = 100(b)^1
b = 110/100
b = 1.10
for increasing rate, b = 1 + r = 1.10, r = 0.10
rate, r = 10%
The base is what determines exponential growth or decay

So we just add 8 1/6 + 8 1/6 + 6 2/3 + 6 2/3
but before we can add them up we need to make our fractions have the same denominators
so we multiply the 2/3 by 2 to give us 4/6 then we can add the fractions together
1/6 + 1/6 + 4/6 + 4/6 = 10/6 or 1 4/6
then add 8 + 8 + 6 + 6 + 1 4/6 = 29 4/6 feet

Answer:
-1.8 < 1 2/3 < 1.45 < 1- 3/8 < 9.3
Step-by-step explanation:
-1 2/3= -1.67 min
-1 3/8 = -1.375 min
so 7he least to greatest is
-1.8 < 1 2/3 < 1.45 < 1- 3/8 < 9.3
The ordered list from least to greatest is -1.8 < -1 2/3 < -1.45 < -1 3/8
What is a mixed fraction?
A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder.
So, a mixed fraction is a combination of a whole number and a proper fraction.
According to the given question:
Gina's relative time list is [tex]-1\frac{2}{3}[/tex] , -1.45, -1.8, [tex]-1\frac{3}{8}[/tex]
Converting mixed fractions to decimal forms to make comparison easy.
-1 2/3 = -1 + 2/3 = - 1.6 min
-1 3/8 = -1 + 3/8 = -1.375 min
Hence the new list is - 1.6, - 1.45, - 1.8, - 1.375
Arranging from least to greatest as follows
-1.8 < - 1.6 < - 1.45 < - 1.375
- 1.8 < -1 2/3 < -1.45 < -1 3/8

F: initial value of 100 decreasing at a rate of 5%
a = 100, rate, r = 5%, b = 1 - 0.05 = 0.95
