Child is prescribed amoxicillin to be given 3 times per day. If she weighs 81 pounds, the maximum dose that she should receive is 500mg.
First, we need to convert the weight of the child from pounds to kilograms. We can do this by dividing the weight in pounds by 2.205 to get the weight in kilograms:
81 pounds÷2.205=36.74 kg
Next, we can calculate the maximum dose of amoxicillin that the child should receive per day by multiplying her weight in kilograms by 40 mg/kg:
36.74 kg×40 mg/kg=1469.6 mg
Since the maximum dose should not exceed 1500 mg per 24 hour period, the child should receive no more than 1500 mg of amoxicillin per day.
Finally, we need to divide the maximum daily dose by 3 to determine the maximum dose per individual dose, since the medication is prescribed to be given 3 times per day:
1500 mg÷3=500 mg
Therefore, the maximum dose of amoxicillin that the child should receive per individual dose is 500 mg.

in an arithmetic sequence, the sum of the second and eighth terms is $5$, and the product of the fourth and fifth terms is also $5$. what is the sum of the first $20$ terms of this sequence?
The sum of the first $20$ terms of the arithmetic sequence is $420$.
In an arithmetic sequence, the sum of the second and eighth terms is $5$, and the product of the fourth and fifth terms is also $5$. The sum of the first $20$ terms of this sequence can be calculated using the following formula:
Sum of the first $20$ terms = $20$/2($a_1 + a_{20})$, where $a_1$ is the first term of the sequence and $a_{20}$ is the twentieth term of the sequence.
Therefore, we need to find the first term of the sequence and the twentieth term of the sequence. To find the first term, we use the following equation:
$5 = a_2 + a_8$, where $a_2$ is the second term and $a_8$ is the eighth term.
To find the twentieth term, we use the following equation:
$5 = a_4 \times a_5$, where $a_4$ is the fourth term and $a_5$ is the fifth term.
Solving both equations, we get $a_2 = 1$ and $a_{20} = 40$. Then, we can calculate the sum of the first $20$ terms of the sequence:
Sum of the first $20$ terms = $20$/2($1 + 40$) = $420$.
Therefore, the sum of the first $20$ terms of the arithmetic sequence is $420$.

Determine if the given functions are even, odd or neither f(x)=x^2-7
The function f(x) = x² - 7 is an example of a function that is neither even nor odd, as it does not exhibit either type of symmetry.
To determine whether a function is even, odd, or neither, we need to examine its algebraic form and look for a particular type of symmetry.
Let's apply this concept to the given function, f(x) = x² - 7. To determine whether f(x) is even or odd, we need to evaluate f(-x) and compare it to f(x).
f(-x) = (-x)² - 7 // substitute -x for x
= x² - 7 // simplify
Comparing f(-x) to f(x), we can see that they are not equal:
f(-x) = x² - 7
f(x) = x² - 7
Since f(-x) is not equal to f(x), the function is not even. To determine whether it is odd, we need to evaluate f(-x) + f(x) and see if the result is zero.
f(-x) + f(x) = (x² - 7) + (x² - 7) // substitute -x for x in the second term
= 2x² - 14
Since f(-x) + f(x) is not equal to zero for all values of x, the function is not odd either.
Therefore, we can conclude that the given function, f(x) = x² - 7, is neither even nor odd.

The value of angle x in the right triangle KJI is approximately 63.4 degrees.
What is trigonometric ratios ?
Trigonometric ratios are mathematical functions that relate the angles of a right triangle to the lengths of its sides. The three primary trigonometric ratios are sine, cosine, and tangent, which are abbreviated as sin, cos, and tan, respectively.
These ratios are defined as follows:
Sine (sin) of an angle is the ratio of the length of the side opposite to the angle to the length of the hypotenuse.
Cosine (cos) of an angle is the ratio of the length of the adjacent side to the angle to the length of the hypotenuse.
Tangent (tan) of an angle is the ratio of the length of the side opposite to the angle to the length of the adjacent side.
Finding the value of x :
We can use the trigonometric ratios to find the value of angle x in the right triangle KJI.
First, we can use the Pythagorean theorem to find the length of the hypotenuse KI:
[tex]KI^2 = KJ^2 + JI^2[/tex]
[tex]KI^2 = 27^2 + 48^2[/tex]
[tex]KI^2 = 729 + 2304[/tex]
[tex]KI^2 = 3033[/tex]
[tex]KI =\sqrt{3033}[/tex]
Next, we can use the sine function to find the value of angle I:
[tex]sin(I) = JI / KI[/tex]
[tex]sin(I) = 48 / \sqrt{3033}[/tex]
[tex]I = sin^-1(48 / \sqrt{3033})[/tex]
[tex]I = 63.4[/tex] degrees
Therefore, the value of angle x in the right triangle KJI is approximately 63.4 degrees.

1. A rain barrel collects water off the roof of a house during three hours of heavy rainfall. The height of the water in the barrel increases at the rate of r(t) = 47-15 feet per hour, where is the time in hours since the rain began. At time t = 1 hour, the height of the water is 0. 75 foot. What is the height of the water in the barrel at time = 2 hours? (A) 1. 361 ft (B) 1. 500 ft (C) 1. 672 (D) 2. 111
As per integration, the height of the water in the barrel at time = 2 hours is 1.672 feet (option C).
The formula is r(t) = 47-15, where t is the time in hours since the rain began. This formula tells us how fast the water level is changing at any given time t.
In this case, we're asked to find the height of the water in the barrel at t = 2 hours, given that the height at t = 1 hour is 0.75 feet. To solve this problem, we'll integrate the rate formula from t = 1 to t = 2, and add the starting height of 0.75 feet.
∫(47-15)dt from t=1 to t=2 = [47t-15t] from t=1 to t=2 = 0.922
So the total increase in height from t=1 to t=2 is 0.922 feet. Adding this to the starting height of 0.75 feet, we get the height of the water at t=2:
0.75 + 0.922 = 1.672 feet
Therefore, the correct option is (C).

What is linear function ?
A linear function is a mathematical function that can be represented by a straight line on a graph. It has the form of:
y = mx + b
where m is the slope of the line, which determines how steeply the line rises or falls, and b is the y-intercept, which is the point where the line crosses the y-axis.
According to the question:
If Daisy calls in sick, then Lisa will be the only stylist at the salon, and all customers will go to her. Let's use x to represent the number of Lisa's customers. Then the income generated by Lisa's customers can be represented by the equation:
18x = projected income
We can solve for x by dividing both sides of the equation by 18:
x = projected income / 18
Substituting the given projected income of $216, we get:
x = 216 / 18 = 12
Therefore, Lisa would need to serve 12 customers to attain the projected income if Daisy calls in sick that day.

10 more than the product of 2 and a number value
Answer:

also,

Step-by-step explanation:
"a number value" is the unknown, so use a variable (letter) I used x, but could be almost any letter (avoid e and i, they have other math meanings)
"10 more than" means to add on 10. You can do that up front or at the end. Order is way more important for subtracting, so no worries here.
"product" means multiplying. So the "product of 2 and a number" is 2x.
So to translate this word phrase into an algebraic expression, you get:
10 + 2x
but also 2x + 10 is the same thing.
a line segment has endpoints (0, 5) and (6, 5). after the line segment is reflected across the x-axis, how long will it be?
The length of the reflected line segment is approximately 11.66 units.
The endpoints of the line segment mentioned in the question are (0,5) and (6,5). After the line segment is reflected across the x-axis, the endpoints of the reflected line segment are (0, -5) and (6, -5).To find the length of the reflected line segment, we will use the distance formula.
Using the distance formula:d = √[(x₂ - x₁)² + (y₂ - y₁)²]d = √[(6 - 0)² + (5 - 5)²]d = √[36 + 0]d = √36d = 6 units. So the length of the original line segment is 6 units.Now, let's find the length of the reflected line segment.Using the distance formula :d = √[(x₂ - x₁)² + (y₂ - y₁)²]d = √[(6 - 0)² + (-5 - 5)²]d = √[36 + 100]d = √136d = 11.66 (approx) units. So the length of the reflected line segment is approximately 11.66 units.

Evelyn buys bracelets thats cost $6 each and three purses that cost $12 each. The cost of evelyns total purchase is $60. Write and equation thar can be used to find n, the number of bracelets that evelyn buys
b + 2p = 10 ,we have an equation that relates the number of bracelets to the number of purses and the total cost of the purchase. if Evelyn buys two purses, she also buys six bracelets.
Let's start by defining our variables. We'll let "b" represent the number of bracelets that Evelyn buys and "p" represent the number of purses she buys.
We know that each bracelet costs $6 and each purse costs $12. We also know that her total purchase is $60.
Using this information, we can create an equation:
6b + 12p = 60
Now we want to solve for "b", which represents the number of bracelets. To do this, we need to isolate "b" on one side of the equation. We can start by simplifying the equation by dividing both sides by 6:
b + 2p = 10
Now we have an equation that relates the number of bracelets to the number of purses and the total cost of the purchase. We can use this equation to find the value of "b" given any value of "p". For example, if Evelyn buys two purses, we can substitute "p = 2" into the equation and solve for "b":
b + 2(2) = 10
b + 4 = 10
b = 6
So if Evelyn buys two purses, she also buys six bracelets.
In general, we can see that the equation tells us that for every two purses that Evelyn buys, she buys one less bracelet. This makes sense because purses are more expensive than bracelets, so as she buys more purses, she can afford fewer bracelets.

what is the average rate of change of f(x) from x = -3 to x = 6? f(x) = x^2 + 4x − 15 enter your answer in the blank.
The average rate of change of f(x) from x = -3 to x = 6 is 7.
What is meant by average?
The term "average" is used to describe a number that represents the central or typical value in a set of data. There are several different types of averages, including the mean, median, and mode.
To find the average rate of change of a function, we need to compute the difference between the function values at the two given points, and then divide by the difference in the input values.
For the function [tex]f(x) = x^2 + 4x - 15[/tex], the value of the function at [tex]x = -3[/tex] is:
[tex]f(-3) = (-3)^2 + 4(-3) -15 = 9 - 12 - 15 = -18[/tex]
The value of the function at [tex]x = 6[/tex] is:
[tex]f(6) = 6^2 + 4(6) - 15 = 36 + 24 - 15 = 45[/tex]
The difference in the function values is:
[tex]f(6) - f(-3) = 45 - (-18) = 63[/tex]
The difference in the input values is:
6 - (-3) = 9
Therefore, the average rate of change of f(x) from x = -3 to x = 6 is:
average rate of change = [tex](f(6) - f(-3)) / (6 - (-3)) = 63 / 9 = 7[/tex]
So, the average rate of change of f(x) from x = -3 to x = 6 is 7.

What is the percentage change of the number of customers that visited the store in the first week to the number of customers that visited the store in the second week?
The percentage change in the visit of total number of customers in the second week as compare to first week is equal to 16.67%.
Total number of customers visited the store in the first week = 360
Total number of customers visited the store in the second week = 300
Percentage Change = (|First week - second week / First week) x 100%
Substitute the value of the number of customers in different weeks in the formula we get,
Percentage Change
= (|300 - 360| / 360) x 100
= (60 / 360) x 100
=( 100 / 6 )
= 16.66666%
= 16.67%
Therefore, the percentage change in the number of customers that visited the store from the first week to the second week is a decrease of 16.67%.
