find the derivative by first principle rule f(x)=3÷x+2
Answer:
The derivative of f(x) = 3 ÷ x + 2 is f'(x) = -3 ÷ (x+2)².
Step-by-step explanation:
This is found by using the first principle method of differentiation, which states that the derivative of a function is the rate of change of the function with respect to the indepedent variable. In other words, the derivative of a function measures how much the output of the function changes with respect to a small change in the input.
To find the derivative of f(x) = 3 ÷ x + 2, we start by taking the limit as h approaches 0 of the difference quotient (f(x + h) - f(x)) ÷ h.
The difference quotient is (3 ÷ (x + h + 2) - 3 ÷ (x + 2)) ÷ h. Simplified, this becomes 3h ÷ (x + h + 2)(x + 2).
When h approaches 0, the difference quotient becomes 3 ÷ (x + 2)², which is the derivative of f(x).

M varies jointly as r² and as l. If M = 20 when I = 8 and r = 2, find: (a) the law connecting these variables, (b) r when M = 400 and l=10.
Answer:
(a) Law connecting the variables:
[tex]M = \frac{5}{8}Ir^{2}[/tex]
(b) r = 8 and r = -8
Step-by-step explanation:
(a) Equation for a joint variation is:
[tex]M = KIr^{2}[/tex] where K is the constant
Substituting the provided values of M, I and r:
= [tex]20 = K(8)(2^{2} )[/tex]
= [tex]20 = K(8)(4)[/tex]
= 20 = 32K
= [tex]K = \frac{20}{32}[/tex]
[Divide the numerator and the denominator by the highest common factor (i.e. 4)]
= [tex]K = \frac{5}{8}[/tex]
Therefore:
[tex]M = \frac{5}{8}Ir^{2}[/tex]
(b) [tex]M = \frac{5}{8} I r^{2}[/tex]
Substituting the values of M and I:
[tex]400 = \frac{5}{8} (10)r^{2}[/tex]
[tex]400 = \frac{5}{8} (10)r^{2}[/tex]
[tex]400 = \frac{50}{8} r^{2}[/tex]
[tex]\frac{(400)(8)}{500} =r^{2}[/tex]
[tex]\frac{3200}{50} = r^{2}[/tex]
[tex]64 =r^{2}[/tex]
Taking the square root on both sides of the equation:
[tex]r = \sqrt{64}[/tex]
[tex]r = 8[/tex] and [tex]r = -8[/tex]
Using a ID reader while checking IDs can can make it easier to
Answer:
Using an ID reader while checking IDs can make it easier to quickly and accurately verify the authenticity of the ID and the information it contains
Step-by-step explanation:
When checking IDs, it might be simpler to quickly and precisely confirm the validity of the ID and the information it includes by using an ID reader. RFID (radio frequency identification) or barcode or magnetic stripe scanning technology is used by ID readers to swiftly read and decipher the data on the ID. Since there is no longer a need to manually read and compare the information on an ID to a reference document, doing so can speed up and improve the efficiency of ID verification. By automatically cross-referencing the information with a database to confirm that the ID is legitimate and the person presenting it is the legal owner, ID scanners may also aid in the prevention of mistakes and fraud.
Answer: Identify security features

Using an ID reader while checking IDs can make it easier to identify security features that don't appear under regular light. O enlarge the small text of microprinting, display data associated with the ID such as age and other information. spot pinholes, cut marks, and other evidence of tampering.
Marc just bought an SUV for 52,000. This is 7,600 less than twice what his wife paid for her car last year. How much did his wife pay (in dollars) for her car
Answer:
Let's call the amount his wife paid for her car "x". We know that:
Marc's car = $52,000
Marc's car = 2x - $7,600
We can substitute the first equation into the second equation
52,000= 2x-7600
52,000+7600=2x
59,600=2x
x=29,800
His wife paid $29,800 for her car.
Answer:
$29,800.00
Step-by-step explanation:
52000 = 2x - 7600 Add 7600 to both sides
52000 + 7600 = 2x
59600 = 2x Divide both sides by 2
29800 = x

toddler triplets whose names are red, green and blue each have a coat whose colour is given by their name, but they aren't clear on which coat belongs to which of them. when they go out, red chooses a coat at random among the three coats, green chooses a coat at random among the remaining two coats and blue is left to take the remaining coat. how many ways are there for exactly one of the toddler triplets to end up with their coat?
Toddler triplets whose names are red, green and blue each have a coat whose colour is given by their name, There are 6ways it can be selected
What are Toddler triplets' ways to select?Generally, There are 3! = 6 ways for the toddler triplets to choose their coats, but since the question asks for exactly one of them to end up with their coat, we need to consider the 3 cases where exactly one of them chooses their coat.
In the case where Red chooses their own coat, there are 2! = 2 ways for Green and Blue to choose their coats. In the case where Green chooses their own coat, there are 2! = 2 ways for Red and Blue to choose their coats. In the case where Blue chooses their own coat, there are 2! = 2 ways for Red and Green to choose their coats.
So in total, there are 2 + 2 + 2 = 6 ways for exactly one of the toddler triplets to end up with their coat.

The amount that will be realized after 7years is $3459.5
What is compound interest?Compound interest is when you earn interest on both the money you've saved and the interest you earn.
Amount in Compound interest is given as:
A = P(1+r/n)^nt
Where A is the amount
P is the principal

The average speed for the whole journey will be 62.33 km per hour.
How to calculate the speed?Speed is the rate at which an object's location changes in a particular direction. The distance traveled on relation changes to a particular direction. The distance in relation to the time it took to travel the distance is the speed. It's a scalar quantity.
Since Dwight drives 85 km at an average speed of 120 km/h and then 6 km at 90 km/h without stopping.

3/4 divided by 1/2 - using unit rate proportionality
To divide 3/4 by 1/2 using unit rate proportionality, we can set up a proportion with 3/4 as the numerator and 1/2 as the denominator, and then cross-multiply and solve for the unknown value.
3/4 / 1/2 = X
To solve for X, we can cross-multiply to get:
(3/4) * (2/1) = X * (1/2)
Which simplifies to:
3/2 = X
So 3/4 divided by 1/2 is equal to 3/2.
It's important to note that when dividing fractions, we can also simply invert the divisor and multiply the two fractions, 3/4 * 2/1 = 6/4 =3/2.

Answer:
The commutative property of addition states that the order of the numbers being added does not affect the result of the addition. For example, "a + b = b + a" is the commutative property of addition.The associative property of addition states that when three or more numbers are being added, the grouping of the numbers being added does not affect the result. For example, "(a + b) + c = a + (b + c)" is the associative property of addition.In simple terms, the commutative property of addition allows for numbers to be added in any order and still get the same result, while the associative property of addition allows for numbers to be grouped in any way and still get the same result.Hope this helps!

John spent 15 minutes developing an estimate for a job. The job itself took 2 hours, 30 minutes to complete. What is the ratio of the time
spent on the job estimate to the total time spent on this job? Submit answer as #:# or fraction.
Answer: The ratio of the time spent on the job estimate to the total time spent on this job is 1/10. Alternatively, it can also be represented as 1:10
Step-by-step explanation:
To find the ratio of the time spent on the job estimate to the total time spent on the job, we need to divide the time spent on the estimate by the total time spent on the job, and then express the result as a fraction.
First, we need to convert both times to minutes.
15 minutes for the job estimate
2 hours = 2*60 = 120 minutes
30 minutes
Total time spent on the job = 120 + 30 = 150 minutes
Now we can divide the time spent on the estimate by the total time spent on the job:
15 minutes / 150 minutes = 1/10
So the ratio of the time spent on the job estimate to the total time spent on this job is 1/10. Alternatively, it can also be represented as 1:10
How much would you need to invest in a money market account if you would like to have $5,000 in the account at the end of 3 years? The account provides an APR of 5% compounded monthly.
Answer:
To calculate the amount you would need to invest in a money market account to have $5,000 at the end of 3 years, we can use the formula for future value of an investment:
FV = PV(1+r)^n
where FV is the future value of the investment, PV is the present value of the investment, r is the interest rate (expressed as a decimal), and n is the number of compounding periods.
In this case,
FV = $5,000 (future value)
r = 5% (APR) = 0.05 (as a decimal)
n = 3 years * 12 (months) = 36
So we can use the formula:
PV = FV / (1 + r)^n
PV = $5,000 / (1 + 0.05)^36
PV ≈ $3,716.76
So you would need to invest $3,716.76 in the money market account to have $5,000 in the account at the end of 3 years.
