Find a formula for a function of the form y=bxe^−ax with local maximum at (1,2.2073). y=________
The required formula is y = 6x e⁻ˣ for a function of the form y=bxe^−ax with the local maximum at (1,2.2073).
What are Maxima of a Function?A function curve has peaks known as maxima. There can be an unlimited number of peaks.
The given function of the form as:
y = bxe⁻ᵃˣ y' = be⁻ᵃˣ (1-ax)
Plug point (x,y) = (1, 2.2073) into equation: 2.2073 = 6be⁻ᵃ
Now plug in y' = 0 at the same x value: 0 = be-6ᵃ(1-6a) or a = 1
and y' = be⁻ᵃ(-a + 1) = 0 giving a = 1
From first equation 2.2073 = b e⁻¹ so b = 2.2073e = 6
So the required formula is y = 6x e⁻ˣ
To find b, plug an into the first equation. The sign of the first derivative shifts from + to -, indicating that it is a maximum critical point.
You may graph the equation using your constants and observe that the point (1, 2.2073) is the maximum.
Therefore, the required formula is y = 6x e⁻ˣ.

write the algebraic expression for the verbal statement. Let x represent the unknown number. 3 less than twice the sum of a number and 4
The algebraic expression for '3 less than twice the sum of a number and 4' where x is the unknown number is
'2(x + 4) - 3'.
The algebraic expression for the verbal statement "3 less than twice the sum of a number and 4" can be written as follows:
First, let's represent the unknown number by x. The phrase 'the sum of a number and 4' translates to x + 4. 'Twice this sum' means we multiply the expression by 2, resulting in 2(x + 4). Finally, '3 less than' indicates that we need to subtract 3 from this expression. Therefore, the complete algebraic expression is 2(x + 4) - 3.

what is 5-2y=3x in standard form?
To write 5 - 2y = 3x in standard form, you rearrange it to Ax + By = C, resulting in the equation 3x - 2y = -5, which is in standard form as requested.
To write the equation 5 - 2y = 3x in standard form, you want to arrange it to Ax + By = C, where A, B, and C are integers, and A should not be negative. Here's how you can do it:
First, we will move the term involving x to the left side of the equation by subtracting 3x from both sides:3x - (5 - 2y) = 3x - 3xThis simplifies to:-3x + 2y = 5Finally, to keep A positive, if necessary, multiply the entire equation by -1:3x - 2y = -5Thus, the standard form of the equation is 3x - 2y = -5.

You buy a container of cat litter for $11.50 and a bag of cat food for x dollars. The total purchase is $16.80, which includes 5% sales tax. Write and solve an equation to find the cost of the cat food.
let cat food = x
total plus 5% = 105% = 1.05
1.05 * (11.50 + X) = 16.80
12.075 + 1.05x = 16.80
1.05x = 16.80-12.075
1.05x = 4.725
x = 4.725 / 1.05
x= 4.50
the cat food cost $4.50
11.50 +4.50 = 16.00
16.00 * 0.05 = 0.80
16.00 + 0.80 = 16.80
What is r, the common ratio, in the geometric sequence 2, −14, 98, −686
Answer:
The common ratio r is -7.
Step-by-step explanation:
The common ratio of a geometric sequence is the division of the term [tex]a_{n+1}[/tex] by the term [tex]a_{n}[/tex].
In this problem, we have that:
[tex]a_{1} = 2, a_{2} = -14, a_{3} = 98, a_{4} = -686[/tex].
So the common ratio r is:
[tex]r = \frac{-14}{2} = \frac{98}{-14} = \frac{-686}{98} = -7[/tex]
The common ratio r is -7.

The range of the first relation is {-5, -4, 2}, and the domain of the second relation is {-1, 1, 3}.
The range of a relation is the set of all second elements in each ordered pair. For the relation R = {(3, -5), (1, 2), (-1, -4), (-1, 2)}, the range is the set of second elements {-5, 2, -4, 2}. When we list the unique values, we get the range as {-5,-4, 2}.
The domain of a relation consists of all the first elements in each ordered pair. Given the relation R = {(3, -2), (1, 2), (-1, -4), (-1, 2)}, the domain is the set of first elements {3, 1, -1, -1}. The domain with unique values is {-1, 1, 3}.
While sailing toward a statue, a sailor in a boat observed that at a certain point, the angle of elevation of the tip of the torch was 25 degrees 25°. after sailing another 110 110 meters toward the statue, the angle of elevation became 43 degrees 50 prime 43°50′. how tall is the statue?
The height of the statue is 97.6 meters
The Breakdown
To determine the height of the statue, we can use trigonometry and create a right triangle with the sailor, the tip of the torch, and the top of the statue.
Assuming the height of the statue is "h" (in meters). The distance between the sailor and the statue is the sum of the initial distance and the additional distance sailed, which is 110 meters.
In the first observation, the angle of elevation is 25 degrees. This means that the tangent of the angle is equal to the height of the statue divided by the initial distance between the sailor and the statue:
tan(25°) = h / initial distance
Similarly, in the second observation, the angle of elevation is 43 degrees and 50 minutes. We need to convert this angle to decimal degrees before using it in calculations. 50 minutes is equal to 50/60 = 5/6 degrees.
So, the angle of elevation in decimal degrees is 43 + 5/6 = 43.8333 degrees.
Now, we can use the tangent function again to relate the height of the statue to the new distance between the sailor and the statue:
tan(43.8333°) = h / (initial distance + 110)
We have two equations with two unknowns (h and initial distance). We can solve this system of equations to find the height of the statue.
Solving the first equation for the initial distance:
initial distance = h / tan(25°)
Substituting this value into the second equation, we get:
tan(43.8333°) = h / (h / tan(25°) + 110)
Now, we can solve this equation for h:
h = (tan(43.8333°) × 110) / (1 - tan(43.8333°) / tan(25°))
Using a calculator, we find that:
tan(43.8333°) ≈ 0.957
tan(25°) ≈ 0.466
Substituting these values into the equation:
h = (0.957 × 110) / (1 - 0.957 / 0.466)
h ≈ 97.6 meters
Therefore, the height of the statue is 97.6 meters.
There are 8 people fishing at Lake Connor: 5 have fishing licenses, and 3 do not. An inspector chooses two of the people at random. What is the probability that the first person chosen has a license and the second one does not? Write your answer as a fraction in simplest form.
Answer:3/28
Step-by-step explanation:
The probability that the first person chosen has a license and the second one does not is 15/56
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur.
Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
Given that, there are 8 people fishing at lake 5 have fishing licenses, and 3 do not. An inspector chooses two of the people at random. we need to find the probability that the first person chosen has a license and the second one does not
Let us consider the possibility of the first person not having a license, which is:
3/7
Now, after a person has been chosen, there will be 7 people remaining. Assuming that the first person chosen did not have a license, there will be 2 people left in the group without a license.
So, the probability of choosing a person without a license the second time will be:
3/7
In probability, when two events occur together (the word "and" is used), multiplication is carried out.
Therefore, we multiply the two probabilities to get:
5/8 x 3/7 = 15/56
Hence, The probability of choosing two people without a license is 15/56
