If the recommended adult dosage for a drug is D (in mg), then to determine the appropriate dosage e for a child of age a, pharmacists use the equation c = 0.0417D(a + 1).
Suppose the dosage for an adult is 150 mg.
(a) Find the slope of the graph of e. (Round your answer to two decimal places.)
What does it represent?
The slope represents the Select of the dosage for a child for each change of 1 year in age.
(b) What is the dosage for a newborn? (Round your answer to two decimal places.)
ma
Answers
a) The slope shows that the appropriate dose c for an older child increase by 6.225 mg if the child is one year older.
b) The dose for newborn baby is: 6.225 mg
The equation of a line in slope intercept form is:
y = mx + c
where: m is slope and c is y-intercept
(a) Let a be an age of an child in years. Then:
c = 0.0417Da + 0.0417D
Where D is a constant
Since D = 150 mg, then we have:
The slope of the graph = 0.0417(150)
= 6.225 mg/year
The slope shows that the appropriate dose c for an older child increase by 6.225 mg if the child is one year older.
(b) Newborn baby: a=0
Thus:
c(0) = 0 + 6.225
= 6.225 mg

A bag has 6 blue cubes, 3 red cubes, and 3 green cubes. If you draw a cube and replace it in the bag 120 times, which of the following amounts would you expect to pull?
Answers
The expected values are 60 blues, 30 reds and 30 greens
Which amount would you expect to pull?From the question, we have the following parameters that can be used in our computation:
6 blue cubes, 3 red cubes, and 3 green cubes
This means that we have the following proportions
Blue = 6/(6 + 3 + 3) = 1/2
Red = 3/(6 + 3 + 3) = 1/4
Green = 3/(6 + 3 + 3) = 1/4
If you draw a cube and replace it in the bag 120 times, we have
Blue = 1/2 * 120 = 60
Red = 1/4 * 120 = 30
Green = 1/4 * 120 = 30
Hence, the expected values are 60 blues, 30 reds and 30 greens

m(10) - 3(10)^2
m(10) = 3(2)^10
Answers
The correct equation that models how many mice there will be in the lab after 10 months is m(10) = 3 × 2^10.
We have,
From the given data, we can see that the number of mice is being multiplied by 2 every month.
That means the growth is exponential.
We can use the formula for exponential growth:
[tex]m(t) = a \timesr^t[/tex]
where m(t) is the total number of mice after t months, a is the initial number of mice (when t = 0), and r is the common ratio
From the given data, we can see that when t = 0, there are 3 mice.
So, a = 3.
Also, we can see that the common ratio is 2 (i.e., the number of mice is being multiplied by 2 every month).
Now,
The equation that models how many mice there will be in the lab after 10 months is:
m(10) = 3 × 2^10

Which expression is equivalent to

Answers
The trigonometric expression 1/sin(2x) - cos(2x)/sin(2x) = tanx
What is a trigonometric expression?A trigonometric expression is an equation that contains trigonometric ratios.
Given the expression 1/sin(2x) - cos(2x)/sin(2x), we need to find the expression that is equivalent to it.
So, we proceed as follows.
1/sin(2x) - cos(2x)/sin(2x) = [1 - cos(2x)]/sin(2x),
Using the trigonometric identity cos2x = cos²x - sin²x and sin2x = 2sinxcosx, we have that
[1 - cos(2x)]/sin(2x) = [1 - (cos²x - sin²x)]/2sinxcosx
= [1 - cos²x + sin²x)]/2sinxcosx
Now, 1 - cos²x = sin²x.
So, substituting this into the equation, we have that
[1 - cos²x + sin²x)]/2sinxcosx = [sin²x + sin²x)]/2sinxcosx
= [sin²x + sin²x)]/2sinxcosx
= 2sin²x/2sinxcosx
= sinx/cosx
= tanx
So, 1/sin(2x) - cos(2x)/sin(2x),= tanx

The solution to the inequality f(x²-2) < f(7x-8) over D₁ = (-∞, 2) is:
-∞ < x < 1 or 1 < x < 6 or 6 < x < 2
Solving Inequality in a given domainGiven the inequality,
f(x²-2) < f(7x-8) over D₁ = (-∞, 2)
We need to find the values of x that satisfy this inequality.
Since we know that f is increasing over its domain, we can compare the values inside the function to determine the values of x that satisfy the inequality.
First, we can find the values of x that make the expressions inside the function equal:
x² - 2 = 7x - 8
Simplifying, we get:
x² - 7x + 6 = 0
Factoring, we get:
(x - 6)(x - 1) = 0
So the values of x that make the expressions inside the function equal are x = 6 and x = 1.
We can use these values to divide the domain (-∞, 2) into three intervals:
-∞ < x < 1, 1 < x < 6, and 6 < x < 2.
We can choose a test point in each interval and evaluate
f(x² - 2) and f(7x - 8) at that point. If f(x² - 2) < f(7x - 8) for that test point, then the inequality holds for that interval. Otherwise, it does not.
Let's choose -1, 3, and 7 as our test points.
When x = -1, we have:
f((-1)² - 2) = f(-1) < f(7(-1) - 8) = f(-15)
Since f is increasing, we know that f(-1) < f(-15), so the inequality holds for -∞ < x < 1.
When x = 3, we have:
f((3)² - 2) = f(7) < f(7(3) - 8) = f(13)
Since f is increasing, we know that f(7) < f(13), so the inequality holds for 1 < x < 6.
When x = 7, we have:
f((7)² - 2) = f(47) < f(7(7) - 8) = f(41)
Since f is increasing, we know that f(47) < f(41), so the inequality holds for 6 < x < 2.
Therefore, the solution to the inequality f(x²-2) < f(7x-8) over D₁ = (-∞, 2) is:
-∞ < x < 1 or 1 < x < 6 or 6 < x < 2

To solve this problem, the first step is distributing the four and the 2.
[tex]4(x-1)=2(6-2x)\\\\4x-4=12-4x[/tex]
So this is our simplified problem.
Step 2: Solve for x
Step 2a: Add 4x to both sides:
(This is because we do not have two variables in the equation, making it easier to solve.
[tex]4x+4x-4=12-4x+4x\\\\8x-4=12+0\\\\8x-4=12[/tex]
Step 2b: Add 4 to both sides:
(We do this to leave the variable on one side and the constant on the other. )
[tex]8x-4+4=12+4\\\\8x+0=16\\\\8x=16[/tex]
Step 2c: Divide both sides by 8:
(The reason why we do this is to isolate the variable without any coefficient in front.)

First, we need to put the data in order from smallest to largest:
$71, 81, 89, 92, 93, 94, 94, 99$
There are 8 numbers in the data set, which is an even number. To find the median, we need to average the two middle numbers.

Julia saved 1 cent ($0.01) on the first day of the month, 2 cents ($0.02) on the second day, 4 cents ($0.04) on the third day, and double the previous day's amount on each successive day. Julia's savings for the first five days are shown in the table below.
On what day will Julia first save an amount greater than $1.00?
Select one:
day 7
day 50
day 8
day 20
Answers
Answer:
Step-by-step explanation:
Because we're told the amount doubles on each successive day, we know we're dealing with an exponential function.
The general form for an exponential function is
[tex]f(x)=ab^x[/tex], where a is the initial value, b is the base, and x is the exponent.
We know that Julia saved $0.01 on the first day so our a value is 0.01.
Because the amount doubles each time, our base is 2.
Furthermore, since we're want to find when Julia's savings exceed $1.00, we can turn the general exponential formula into an inequality where the formula is greater than 1 and solve for x (time in days):
[tex]1.00 < 0.01(2)^x\\100 < 2^x\\log(100) < log(2)^x\\log(100) < x*log(2)\\log(100)/log(2) < x\\6.64 < x\\7 < x[/tex]
We had to round the 6 to the nearest whole number (7) to get the answer.
We can check our work by plugging in both 6.64 for x and 7 for x to see how at 7 days, Julia's savings exceed 1.00
Plugging in 6.64 for x:
[tex]f(6.64)=0.01(2)^6^.^6^4\\f(6.64)=0.01*99.7\\f(6.64)=0.997\\f(6.64)=1.00[/tex]
Using 6.64 for x makes Julia's savings equal 1, but they don't exceed 1
Plugging in 7 for x:
[tex]f(7)=0.01(2)^7\\f(7)=0.01*128\\f(7)=1.28[/tex]

Jolene invests her savings in two bank accounts, one paying 6 percent and the other paying 10 percent simple interest per year. She puts twice as much in the lower-yielding account because it is less risky. Her annual interest is 8602 dollars. How much did she invest at each rate?
Answers
The amount she invested at each rate of interest for the simple interest are $39,100 and $78,200.
Given that,
Jolene invests her savings in two bank accounts.
Rate of interest for one account = 6% per year
Rate of interest for the other account = 10% per year
Let x be the principal amount invested in the account yielding 10% interest.
Interest amount = 0.1x
Principal amount in the account of 6% interest = 2x
Interest amount = 0.06 × 2x = 0.12x
Annual interest = $8602
0.1x + 0.12x = 8602
0.22x = 8602
x = $39,100
Amount invested for 10% interest account = $39,100
Amount invested for 6% interest account = 2 × $39,100 = $78,200
Hence the amount invested are $39,100 and $78,200.

[tex] \sf \longrightarrow \: \frac{m - 12}{2} = \frac{m + 8}{4}\\ [/tex]
[tex] \sf \longrightarrow \: 4(m - 12) =2(m + 8)\\ [/tex]
[tex] \sf \longrightarrow \: 4m \: - 48 =2m + 16\\ [/tex]
[tex] \sf \longrightarrow \: 4m \: - 2m = 16 + 48\\ [/tex]
[tex] \sf \longrightarrow \:2m = 64\\ [/tex]
[tex] \sf \longrightarrow \:m = \frac{64}{2} \: \\ [/tex]
[tex] \sf \longrightarrow \:m = 32 \: \\ [/tex]
[tex] \qquad{ \underline{\overline{ \boxed{ \sf{ \: \: C) \: \: \: 32 \: \: \: \: \: \checkmark }}}}} \: \: \bigstar[/tex]
