CVS is having a sale on vitamins You Purchase 2 bottles of multivitamins at $3.75/bottle 1 bottle of vitamin D
Supplement that costs $4.85 and 2 vitamin C Supplement bottles at $2.95/bottle.How much money wauld be left before tax if you had $20 to spend on this purchase?
Answers
You would have $1.75 left before tax after purchasing all the vitamins.
Here is how to solve the word problemLet's calculate the total cost of the vitamins first.
From the question, we can deduce the following:1 bottle of multivitamins = $3.751 bottle of vitamin D = $4.851 bottle of vitamin C = $2.95
Now, let's calculate the cost of what you got:2 bottles of multivitamins = 2 x $3.75 = $7.501 bottle of vitamin D = 1 x $4.85 = $4.852 bottles of vitamin C = 2 x $2.95 = $5.90
Total cost of the vitamins is = $7.50 + $4.85 + $5.90 = $18.25
If you have $20 (total amount) to spend on this purchase, after spending, you would have: balance = total amount - total cost balance = $20 - $18.25 balance = $1.75
So you would have $1.75 left before tax after purchasing all the vitamins.

Answers
The standard deviation of a sample of data can be computed using the equation
\(\sigma=\sqrt[]{\frac{1}{N}\sum^N_{n\mathop=1}(x_n-\mu)^2}\)where μ stands for the mean of the data and N as the number of samples.
The first step in solving the standard deviation of the given sample is to find the mean. The mean of the data given is
\(\mu=\frac{109+105+112+110+115+106+108+109}{8}=109.25\)The second step is to subtract each number to the mean of the data then get the square of the difference. We have the following
\(\begin{gathered} (x_1-\mu)^2=(109-109.25)^2=0.0625 \\ (x_2-\mu)^2=(105-109.25)^2=18.0625 \\ (x_3-\mu)^2=(112-109.25)^2=7.5625 \\ (x_4-\mu)^2=(110-109.25)^2=0.5625 \\ (x_5-\mu)^2=(115-109.25)^2=33.0625 \\ (x_6-\mu)^2=(106-109.25)^2=10.5625 \\ (x_7-\mu)^2=(1098109.25)^2=1.5625 \\ (x_8-\mu)^2=(109-109.25)^2=0.0625 \end{gathered}\)The third step is to find the sum of these squared differences and get the mean. We get
\(\frac{1}{N}\sum ^N_{n\mathop{=}1}(x_n-\mu)^2=\frac{0.0625+18.0625+7.5625+0.5625+33.0625+10.5625+1.5625+0.0625}{8}=8.933\)Finally, for the last step, get the square root of the result in step 3, we have
\(\sqrt[]{\frac{1}{N}\sum^N_{n\mathop{=}1}(x_n-\mu)^2}=\sqrt[]{8.933}=\pm2.99\)Therefore, the standard deviation of the given data is equal to ± 2.99.

Step-by-step explanation:
use the properties of integration to simplify, then take the integral.
Answer:
First, express the fraction in partial fractions
Write it out as an identity.
As the denominator has a repeated linear factor, the power of the repeated factor tells us the number of times the factor should appear in the partial fraction. A factor that is squared in the original denominator will appear in the denominator of two of the partial fractions - once squared and once just as it is:
\(\dfrac{2x^2+x+1}{(x+3)(x-1)^2} \equiv \dfrac{A}{(x+3)}+\dfrac{B}{(x-1)}+\dfrac{C}{(x-1)^2}\)
Add the partial fractions:
\(\dfrac{2x^2+x+1}{(x+3)(x-1)^2} \equiv \dfrac{A(x-1)^2+B(x+3)(x-1)+C(x+3)}{(x+3)(x-1)^2}\)
Cancel the denominators from both sides of the original identity, so the numerators are equal:
\(2x^2+x+1 \equiv A(x-1)^2+B(x+3)(x-1)+C(x+3)\)
Now solve for A and C by substitution.
Substitute values of x which make one of the expressions equal zero (to eliminate all but one of A, B and C):
\(\begin{aligned}x=1 \implies 2(1)^2+(1)+1 & = A(1-1)^2+B(1+3)(1-1)+C(1+3)\\4 & = 4C\\\implies C & =1\end{aligned}\)
\(\begin{aligned}x=-3 \implies 2(-3)^2+(-3)+1 & = A(-3-1)^2+B(-3+3)(-3-1)+C(-3+3)\\16 & = 16A\\\implies A & =1\end{aligned}\)
Find B by comparing coefficients:
\(\begin{aligned}2x^2+x+1 & = A(x^2-2x+1)+B(x^2+2x-3)+C(x+3)\\ & = (A+B)x^2+(2B-2A+C)x+(A-3B+3C)\end{aligned}\)
\(\begin{aligned}\implies 2x^2 & = (A+B)x^2\\2 & = A + B\\\textsf{substituting found value of A}: \quad2 & = 1+B\\\implies B & = 1 \end{aligned}\)
Replace the found values of A, B and C in the original identity:
\(\implies \dfrac{2x^2+x+1}{(x+3)(x-1)^2} \equiv \dfrac{1}{(x+3)}+\dfrac{1}{(x-1)}+\dfrac{1}{(x-1)^2}\)
Now integrate:
\(\begin{aligned}\displaystyle \int \dfrac{2x^2+x+1}{(x+3)(x-1)^2}\:dx &=\int \dfrac{1}{(x+3)}+\dfrac{1}{(x-1)}+\dfrac{1}{(x-1)^2}\:\:dx\\\\& =\int \dfrac{1}{(x+3)}\:dx\:\:+ \int\dfrac{1}{(x-1)}\:dx\:\:+\int \dfrac{1}{(x-1)^2}\:dx\\\\& = \ln |x+3|+ \ln |x-1|-\dfrac{1}{x-1}+C\end{aligned}\)

How to find the domain and range of the graph?
The domain of a graph is defined as the set of all possible input values that makes the function possible while the range is defined as the set of all possible output values that can result from the possible input values.
Now, we are told that the insect population increases by 20% each month from May 1 to September 1.
The function that represents the insect population after x months is;
f(x) = 100(1.2)ˣ
Thus, the domain is from x = 0 to 4 months inclusive. 0 ≤ x ≤ 4
f(0) = 100(1.2)⁰
f(0) = 100

Use the two given functions to write y as a function of x.
y = -3a + 3, a = -5x + 1
Answers
Answer:
Step-by-step explanation:
To write y as a function of x using the given functions, we can substitute the value of "a" in the first equation with the expression "-5x + 1" from the second equation.
Given:
y = -3a + 3
a = -5x + 1
Substituting the value of "a" in the first equation:
y = -3(-5x + 1) + 3
Now, let's simplify this expression:
y = 15x - 3 + 3
y = 15x
Therefore, y can be expressed as a function of x as:
y = 15x

How do I solve a whole number and a fraction?
Answers
Answer:
To solve a problem involving a whole number and a fraction, you can first convert the whole number to a fraction by writing it as a fraction with a denominator of 1. For example, if the whole number is 4, you can write it as the fraction 4/1.
Then, you can add or subtract the fractions as you would normally, making sure to find a common denominator if necessary. For example, suppose you want to add the whole number 4 and the fraction 3/5. You can first write 4 as the fraction 4/1, giving you:
4/1 + 3/5
To add these fractions, you need to find a common denominator. A common denominator for 1 and 5 is 5, so you can rewrite the fractions with denominators of 5:
4/1 = 20/5
3/5 = 3/5
Now you can add the fractions:
20/5 + 3/5 = 23/5
So the solution to the problem is 23/5.
If you need to multiply or divide the whole number and fraction, you can treat the whole number as a fraction with a denominator of 1 and then perform the multiplication or division as you would normally with fractions.
Step-by-step explanation:
In multiplication, we simply solve by multiplying the whole number by the numerator of the given fraction. We can take the expression 6 • 2/3 for example:
The numerator is 2, so solving would result in (6 • 2)/3 as a fraction. This equals out to 12/3, which can be reduced to 4; this means 6 • 2/3 = 4.
Division, however, is a bit different. When dividing a whole number by a fraction, we use the Skip, Flip, Multiply method. Again, we can use 6 / 2/3 as an example.
1. Skip
Since our first divisor is 6, it remains the same.
2. Flip
Our second divisor is 2/3. Since it is a fraction, we can flip it so it becomes 3/2.
3. Multiply
With our new expression, we can now multiply what we have to find our answer!
6 • 3/2 = 18/2, which reduces to 9.
Now we know that 6 / 2/3 = 9. One thing to consider when dividing a whole number by a fraction is that the whole number is the fraction of the product. In this case, we would say 6 is 2/3 of 9, and this helps us to remember that the quotient always will be larger than what we began with, whereas in multiplication, the product is smaller than what we began with.

Answer:
Graph W
Step-by-step explanation:
The given information describes a radioactive decay process, where the weight of the isotope decreases by half at regular intervals. This type of decay is characteristic of exponential decay.
Based on the description, the graph that represents the weight of the radioactive isotope over time would be a decreasing exponential curve, where the y-axis represents the weight of the isotope (in grams), and the x-axis represents time (in hours).
The initial weight of the isotope is 96 grams, and after each subsequent hour, the weight becomes half of what it was in the previous hour. Therefore, the correct graph would start at 96 grams (the initial weight when x = 0) and then decrease by half every hour. It would be a curve that gets closer and closer to zero but never quite reaches it.
Initial weight: 96 grams
After 1 hour: 96 / 2 = 48 grams
After 2 hours: 48 / 2 = 24 grams
After 3 hours: 24 / 2 = 12 grams
After 4 hours: 12 / 2 = 6 grams
After 5 hours: 6 / 2 = 3 grams
So, the points on the graph would be:
(0, 96), (1, 48), (2, 24), (3, 12), (4, 6), (5, 3)Therefore, the graph that represents the weight of the radioactive isotope over time is Graph W.
