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

Step-by-step explanation:

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.

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

1. The number of days is, 21/5

2. The cost of 100 kg rice is,  4520

3. The teachers required are, 120

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

1. Given that,

3 men can complete a work in 7 days

So, we can say magnitude of work is

M = 3 × 7 =21 unit

now, 5 men are working

So,  magnitude of work is same

M = 5 × n

21 = 5 × n

n = 21/5 days

2. the cost of 25kg rice is 1130

price for 1 kg = 1130/25 =45.2

price for 100 kg = 45.2 × 100

                           =  4520

3. 90 teachers required for 1500 students,

1 teacher is expected to handle 1500/90 students,

So, for 2000 students

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.

The student is not correct. Y = 16x^2 is a function of X.

A function is a mathematical relationship between two variables, where each value of the independent variable (in this case, X) corresponds to exactly one value of the dependent variable (in this case, Y). The equation Y = 16x^2 satisfies this definition.

The fact that X is squared in the equation does not mean that it is not a function of X. In this case, Y is a function of X because for each value of X, there is a unique value of Y determined by the equation Y = 16x^2.

This equation represent the distance an object falls (Y) in a certain amount of time (X) assuming that the only force acting on the object is gravity, and the acceleration due to gravity is constant (approximately 9.8 m/s^2 or 32 ft/s^2). The equation Y = 16x^2 is known as the equation of motion under gravity.

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).

7 goes 0 times into 6, so we write a 0.

                       0.

                   ----------------

               7  |   6.0

Add .0 to 6 to get 6.0

7 goes 8 times into 60.

                           40

                      -    35

                      ---------

40 - 35 = 5

Add another 0 to 6.00 to get 6.000; bring down that zero.

(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]

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

t is the duration and

n is the period of compoundment

r is the rate

n= ¼, r = 3.5/100 = 0.035

therefore A = 2750(1+0.035/0.25)^0.25×7

A = 2750( 1+0.14)^1.75

A= 2750(1.14)^1.75

A = 2750×1.258
