What is exponential expression?An exponential function is a Mathematical function in the form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to.
Given,
Dave drinks 12-ounce cup of coffee each morning
One cup has 136 mg of caffeine
caffeine in his system decreases about 40% every hour
In x hours,
Amount of caffeine in his system
y = a(1 - 40/100)ˣ
or

James purchases a rare coin for $450. The coin appreciates at a rate of 1.2% each year. How much will the coin be worth after 25 years?
Answers
Step-by-Step Explanation:
Price of Rare Coin = $450
Rate at which it appreciates = 1.2%
Price of Rare Coin after 25 years = ?
Therefore,
= 1.2 * 25 = 30%
Hence, price of coin after 25 years:
= (30/100 * 450) + 450
= 135 + 450
= 585
Therefore,
The coin would cost $585 after 25 yrs.

The volume of a cubic cardboard box is 125/8 ft3.
The length of each side of the cardboard box is______
ft.
Answers
Answer:
The answer is
\( \frac{5}{2} \: \: \: feet \\ \)Step-by-step explanation:
Since the cardboard box is a cube all it's sides are equal
Volume(V) of a cube = l³
where l is the length of one side
From the question
\(V = \frac{125}{8} \: {ft}^{3} \)
The length of each side of the cardboard box is
\( {l}^{3} = \frac{125}{8} \\ \sqrt[3]{ {l}^{3} } = \sqrt[3]{ \frac{125}{8} } \\ l = \frac{5}{2} \)
We have the final answer as
\( \frac{5}{2} \: \: \: feet \\ \)
Hope this helps you
Answer:
5/2 ft
Step-by-step explanation:
The volume of a cube is calculated by the following formula.
Rewrite the formula in terms of the side, as shown.
It is given that the volume of the cardboard box is ft3. Substitute this value into the equation to determine the length of each side of the cardboard box.
Therefore, the length of each side of the cardboard box is 2.5 ft.

Ronald is walking at a rate of 3 miles per hour. If he walks for 2 hours and then runs at a rate of 6 miles per hour for another 1 hour, how far did Ronald travel in total?
Answers
Answer:
12Step-by-step explanation:
Ronald's walking speed is 3 miles per hour, and he walks for 2 hours, so he covers 3 * 2 = 6 miles. In the next hour, he runs at a speed of 6 miles per hour, covering an additional 6 miles. Therefore, Ronald traveled a total of 6 + 6 = 12 miles.
A manufacturer produces cherry, peppermint, cinnamon, and orange-flavored gum. Each flavor is available with sugar or sugar-free. The gum
is sold in 2 ounce, 4-ounce, or 8 ounce packages,
How many different types of labels will the manufacturers have to produce?
Answers
Answer: The total number of different types of labels will the manufacturers have to produce = 24.
Step-by-step explanation:
Given: Choices for flavours = 4
Choices for sugar = 2 {either sugar or sugar free}
Choices for the qunatity = 3
By Fundamental counting principle,
Total number of different types of labels will have to produce = (Choices for flavors) x (Choices for sugar)x (Choices for the quantity )
= 4 x 2x 3
=24
Hence, the total number of different types of labels will the manufacturers have to produce = 24.

the function f(x)=-4x^2+18x16 models the predicted sales of a hat after x price increases.
Answers
The predicted sales after 3 price increases is 34.
What are the sales?
It seems there is a mistake in the function you provided.
Assuming that the function is actually:
f(x) = -4x² + 18x + 16
where x represents the number of price increases, we can interpret the function as follows:
The term -4x² represents a parabolic decrease in sales over time, since the coefficient of x² is negative. This means that as the number of price increases (x) increases, the predicted sales will decrease at an increasing rate.The term 18x represents a linear increase in sales over time, since the coefficient of x is positive. This means that as the number of price increases (x) increases, the predicted sales will increase at a constant rate.The constant term 16 represents the initial predicted sales when x = 0 (i.e., before any price increases).We can use this function to make predictions about the future sales of the hat based on the number of price increases that have occurred. For example, if there have been 3 price increases, we can calculate the predicted sales as follows:
f(3) = -4(3)² + 18(3) + 16
= -36 + 54 + 16
= 34
Therefore, the predicted sales after 3 price increases is 34. Note that this is just a prediction based on the given function, and actual sales may differ due to various factors.

here, the probability of each U.S household play video or computer games is fixed as 0.69
Then, the probability of each U.S household not play video or computer games= 1-0.69=0.31
For independent events the probability of their intersection is product of probability of each event.

If the volume of a cube is 729cm^3, what is the surfface area.
Thanks!!
Answers
Answer:
486cm^2
Step-by-step explanation:
cube volume: 729cm^3
cube faces count: 6
How you calculate square area:
s(cm) * s(cm) or just s^2(cm^2)
s = side length
If you want to find out the side length of a cube by its volume. Then simply just remove the ^3 by taking the cubic root (also written ^(1/3))
729^(1/3) = 9
then just calculate the area like i showed earlier:
(9cm)^2 = 81cm^2
But that is only one side of a cube's 6 sides, so multiply by 6:
81cm^2 * 6 = 486cm^2
Hope i could help :D

5. El bloque de la figura se encuentra en reposo en el momento en que empiezan a actuar las fuerzas.

F, = 22.6 N
m = 2 kg
a. Encontrar el valor de la fuerza resultante.
b. Determina su aceleración.
C. Calcula la velocidad del bloque a los 5 segundos de movimiento.
Answers
The resultant force acting on the block is 47.6N.
The acceleration of the block will be 23.8 m/s².
The speed of the block after 5 seconds of movement is 119 m/s.
What is the resultant force?In this question, we need to make use of Newton's second law, hence:
resultant force = mass × acceleration
So, for question a. The value of the resultant force will be obtained by adding the two forces together:
resultant force = F₁ + F₂
= 25N + 22.6N
= 47.6N
b. Its acceleration will be:
acceleration = resultant force / mass
= 47.6N / 2kg
= 23.8 m/s²
c. The speed of the block after 5 seconds of movement will be:
Velocity (v) = u + at
velocity = initial velocity + acceleration x time
Based on the block was initially at rest, the initial velocity is 0.
Hence:
V = acceleration x time
= 23.8 m/s² x 5s
= 119 m/s
Hence the speed of the block after 5 seconds of movement will be: 119 m/s.

One of the sides of a pentagon has length 12. Which of the following points, when paired with (2, 3), will make a side equal to this length?
A) (14, 15)
B) (2, -9)
C) (-2, -3)
D). (-9, 2)
Answers
The correct option for the given sum is option B. The point (2,-9) paired with (2, 3), will make a side equal to this length.
Let the other point of the pentagon will be M(n, o).
The given point be A (a, b)
Also given one of the sides of a pentagon has length 12.
Now, we need to find the distance between the two points,
Distance between two points: |AM| = √\((a-n)^2+(b-o)^2\)
Now,
\(12 = \sqrt{(2-n)^2+(3-o)^2}\)
\((12)^2\) = \((2-n)^2+(3-o)^2\)
\((2-n)^2+(3-o)^2\) = 144 ----------------------------- eq (1)
Now, check every point for the values to match with equation (1)
Option A: \((2-14)^2+(3-15)^2\) = 288. So the option is false.
Option B:
\((2-2)^2+(3-(-9))^2\) =114
0+114 =114
Therefore option B is correct. The other point is (2,-9).

Susan is running a 5k race. The graph of distance vs. time is shown.
What interval is she running the fastest?
Answers
The interval of the graph at which Susan is running fastest is from point A ( 0 , 0 ) to B ( 10 , 3 )
Given data ,
Susan is running a 5k race. The graph of distance vs. time is shown
So , the slope of the first line is m₁
And , the slope of the second line is m₂
where the points are A ( 0 , 0 ) , B ( 10 , 3 ) , C ( 20 , 4 )
Now , slope of AB is
m₁ = ( 3/10 ) = 0.3
And , m₁ = 0.3 kilometers per minute
And , slope of BC is
m₂ = ( 4 - 3 ) / ( 20 - 10 )
m₂ = 1/10
m₂ = 0.1 kilometers per minute
Therefore , the interval is fastest at second line from B ( 10 , 3 ) , C ( 20 , 4 )
Hence , Susan is running fastest is from point A ( 0 , 0 ) to B ( 10 , 3 )
