Answer:
The Horizontal Asymptote is the point (0, a).
The Horizontal Asymptote is the line =
= 0.
Step-by-step explanation:
The following statements are true regarding f(x) = aᵇ:
The Domain of the exponential functions is All Real Numbers.
The Horizontal Asymptote is the line y = 0.
The Range of the exponential functions is f(x) > 0.
What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
The horizontal asymptote is the horizontal line that the graph of the function approaches as x approaches infinity or negative infinity. In this case, the horizontal asymptote is the line y = 0, which means that as x gets very large, the value of f(x) approaches 0.
The domain of the function is the set of all values of x that can be plugged into the function. For exponential functions, the domain is all real numbers because any real number can be raised to any power.
The range of the function is the set of all possible output values that the function can produce. For exponential functions, the range is f(x) > 0, which means that the function can produce any positive real number as output.
The following conclusions about f(x) = aᵇ are correct:
All Real Numbers are the domain of exponential functions.
The line y = 0 is the Horizontal Asymptote.
The exponential functions have a range of f(x) > 0.

Kevin has a coin collection. He keeps 5 of the coins in his box, which is 25% of the collection. How many total coins are in his collection?
Answer:
20 coins
Step-by-step explanation:
[tex]\frac{5}{\frac{25}{100} }[/tex] = 20
Answer:
[tex]\huge\boxed{\sf Total\ collection = 20\ coins}[/tex]
Step-by-step explanation:
25% of the collection = 5 coins
Total collection = 100%So,
100% = 25% + 25% + 25% + 25%
100% = 5 + 5 + 5 + 5

Step-by-step explanation: Slope is rise (how far up or down) over run (how far left to right. Look for points where the line crosses a perfect grid line intersection. The graph goes up to 50 and right 20 (started at 10 and ended at 30). The rise/run is 50/20 or 5/2 reduced.
first, find two places on the line that intersects the grid boxed neatly. This occurs at (10 , 0) and (30 , 50).
slope = change in rise / change in run
slope = change in y / change in x
slope = ( 0 - 50) / (10 - 30)
slope = -50/-20
slope = 50/20
slope = 5/2

The transformation g(x) = -f(x) converts the graph of
f(x) = 8x^2 - 7 into the graph of g(x) = -8x^2 + 7.
What is transformation of graph?
The technique of altering an existing graph or graphed equation to create a different version of the following graph is known as graph transformation. In particular, the change of algebraic equations, it is a typical kind of algebraic problem.
Given: f(x) = 8x^2 - 7.
We have to find what kind of transformation converts the graph
f(x) = 8x^2 - 7 into the graph of g(x) = -8x^2 + 7.
Let,
f(x) = 8x^2 - 7
Multiply both sides by -1.
⇒ -f(x) = -8x^2 - (-7)
- f(x) = -8x^2 + 7
Since g(x) = -8x^2 + 7
⇒ -f(x) = g(x)
⇒ g(x) = -f(x)
Therefore, the transformation g(x) = -f(x) converts the graph of
f(x) = 8x^2 - 7 into the graph of g(x) = -8x^2 + 7.

(Writing Two-Step Equations MC)
A new gaming chair costs $455.95. You have already saved $136.45 and earn $35.50 each week babysitting. Write and solve an equation to determine how many weeks, w, you must babysit to earn enough money to buy the new gaming chair.
35.5 + 136.45w = 455.95; w = 9
35.5w + 136.45 = 455.95; w = 9
35.5w − 136.45 = 455.95; w = 17
35.5w − 455.95 = 136.45; w = 17
The equation that represents the number of weeks that is needed to baby sit to buy gaming chair is 35.5w + 136.45 = 455.95; w = 9 , the correct option is (b) .
In the question ,
it is given that
the cost of the gaming chair = $455.95
amount of money already saved for the gaming chair = $136.45
amount of money earned by baby sitting each week = $35.50 .
let the number of weeks required to baby sit is " w " .
the equation can be represented by
cost of chair = money saved + money earned in w weeks
Substituting the values from above ,
we get
455.95 = 136.45 + 35.5w
On solving further ,
136.45 + 35.5w = 455.95
35.52w = 455.95 - 136.45
35.52w = 319.5
w = 319.5 / 35.52
w = 8.99
w ≈ 9
the number of weeks = 9
Therefore , The equation that represents the number of weeks that is needed to baby sit to buy gaming chair is 35.5w + 136.45 = 455.95; w = 9 .

What price will get him the greatest total revenue? How can you verify that your solution is correct? What assumptions did you make in creating and using this model function
Jeffry will get greatest total revenue when he charges the lemonade $1.40
Given,
The price per servings of lemonade = $0.80
Number of servings = 200
For each $0.10 that he adds to the price, Jeffrey will lose 10 customers.
We have to find the greatest total revenue he got.
Lets check.
0.80 x 200 = $160
0.90 x 190 = $171
1.00 x 180 = $180
1.10 x 170 = $187
1.20 x 160 = $192
1.30 x 150 = $195
1.40 x 140 = $196
1.50 x 130 = $195

Step-by-step explanation:
For these problems, there actually pretty easy. What you do is the numbers like x2 are x times 2. So, like if x is 3, it would be equal to 6 because 3 times 2 is 6. Easy, right?
But this time, it is asking you for GCF. It's harder, but it will be easy after you understand it.
#1
So, it organizes the equation. So x2 gets simplified to x times 2. x*2 is double the amount. x + y and x - z. Take the x's that is 2 x's. So x2. Then y and z which are unknown has the value left. And 1 more thing. Since there is no operation, it turns in to times/multiply. Please don't ask why. Ask it in a new question. So you can cross them off and multiply x2 with y times z. The equation now is basically x2 y times z). y times z. Again, the numbers are unknown. So you need to count them as zero. Add 2 zero's together is 0. Add x2 to 0. Which is x2.
You can now do problem 2 by yourself after you read the explanation. Remember, your answer isn't always like this type of explanation. Some one's work, try this for all your problems related. See if it works.

9. The plane's speed would be of 340 and 350 miles per hour.
10. She runs the downhill portion of the course at a rate of 10 miles per hour.
11. The total time would be of 24 minutes.
How to obtain the velocity?
Velocity is distance divided by time, hence the equations is:
v = d/t.
For the first plane, the velocity and the distances are given by:
v = v + 10, d = 495.
Hence:
v + 10 = 495/t
t = 495/v + 10
For the second plane, the velocity and the distance are:
v = v, d = 510.
Hence:
v = 510/t
t = 510/v
The time is equal, hence the velocity of the slower plane is obtained as follows:
495/v + 10 = 510/v
Applying cross multiplication:
510v + 5100 = 495v
15v = 5100
v = 5100/15
v = 340 mph
For the runner, we have two parts, as follows:
First part: distance of 3 miles, velocity of v - 5, time of t.Second part: distance of 4 miles, velocity of v, time of 1 - t.Hence the equations are given as follows:
v - 5 = 3/t.v = 4/(1 - t).From the first equation, we have that:
v = 5 + 3/t.
Replacing in the second, we have that:
5 + 3/t = 4/(1 - t)
(5t + 3)/t = 4/(1 - t)
Applying cross multiplication, we have that:
(5t + 3)(1 - t) = 4t
-5t² + 2t + 3 = 4t
5t² + 2t - 3 = 0.
The positive solution, as time is a positive measure, of the quadratic equation is given by:
t = 0.6.
Hence the velocity of the downhill part is given by:
v = 4/(1 - t) = 4/0.4 = 10 miles per hour.
What is the together rate?The together rate is the sum of each separate rates.
The rates in this problem are given as follows:
Jason: 1/30.Kevin: 1/120.Together: 1/x.Hence:
1/x = 1/30 + 1/120
1/x = 5/120

The flower arrangements with $200 has lower unit price than the flower arrangements with $70 unit price.
What is meant by unit price?The average price of a product is calculated by dividing the total sales income by the total number of units sold. When a same product is supplied in variants, such as bottle sizes, managers must define "similar" units. Average prices can be estimated by dividing distinct unit selling prices by the percentage of unit sales (mix) for each product variant. When we utilize a standard rather than an actual mix of sizes and product variations, the result is price per statistical unit. Statistical units are sometimes known as analogous units.
Unit price for 15 flower arrangements for $200 is,
200/15=13.33
Unit price for 5 flower arrangements for $70 is,
70/5=14
Therefore, 14>13.33
