Step-by-step explanation:

To check whether the given credit card number is valid or not, we need to apply the Luhn algorithm or the mod-10 algorithm. The Luhn algorithm works by adding up all the digits in the credit card number and checking if the sum is divisible by 10 or not. If it is, then the credit card number is considered valid, otherwise, it is invalid.

Let's apply the Luhn algorithm to the given credit card number:

Step 1: Starting from the rightmost digit, double every second digit

| 5 | 4 | 2 | 4 | 9 | 8 | 1 | 3 | 2 | 7 | 2 | 0 | 0 | 0 | 8 | 5 |

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

| | 8 | | 8 | | 16| | 6 | | 14| | 0 | | 0 | | 10|

Step 2: If the doubled value is greater than 9, add the digits of the result

| 5 | 4 | 2 | 4 | 9 | 8 | 1 | 3 | 2 | 7 | 2 | 0 | 0 | 0 | 8 | 5 |

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|

| | 8 | | 8 | | 7 | | 6 | | 5 | | 0 | | 0 | | 1 |

Step 3: Add up all the digits in the credit card number, including the check digit

5 + 4 + 2 + 4 + 9 + 8 + 1 + 3 + 2 + 7 + 2 + 0 + 0 + 0 + 8 + 5 + 1 = 61

Step 4: If the sum is divisible by 10, then the credit card number is valid, otherwise, it is invalid.

61 is not divisible by 10, therefore the given credit card number is invalid.

Hence, it can be concluded that 5424 9813 2720 0085 is an invalid MASTERCARD credit card number.

Answer:

Step-by-step explanation:

You want the slope of a line tangent to the curve y = 2x² +4x, and a graph of the tangent lines at x=-2 and x=0.5.

The slope of the curve is given by the derivative of the polynomial:

  y' = 4x +4 . . . . . . general expression for slope at P(x, y)

The slope at x = -2 is ...

  y' = 4(-2) +4 = -4

The value of y at x=-2 is ...

  y = (2(-2) +4)(-2) = 0

In point-slope form, the equation of the tangent line with slope -4 at point (-2, 0) is ...

  y -k = m(x -h) . . . . . . . line with slope m through point (h, k)

  y -0 = -4(x +2) . . . . . line with slope -4 through point (-2, 0)

  y = -4x -8 . . . . . tangent line at x = -2

The slope at x = 0.5 is ...

  y' = 4(0.5) +4 = 6

The function value is ...

  y = (2(0.5) +4)(0.5) = 2.5

The point-slope equation of the tangent is ...

  y -2.5 = 6(x -0.5) . . . . . tangent line at x = 0.5

__

Additional comment

The derivative of a function y can be signified by a prime: y'. The derivative is the slope. The slope of the curve is the same as the slope of a tangent to the curve, so we have ...

  mtan = y' = 4x+4

Answer: Let the length of the hypotenuse be x

Applying the Pythagorean theorem we have :

x²=20²+48²

⇒x²=2704

⇒x=52( ∀ x >= 0 )

Step-by-step explanation:

Let assume the hypotenuse(longest side of right triangle) be x

By Pythagoras theorem

\( \bf \large \longrightarrow \: {c}^{2} \: = \: {a}^{2} \: + \: {b}^{2} \)

Applying Pythagoras theorem

\( \bf \large \implies \: {x}^{2} \: = \: {20}^{2} \: + \: {48}^{2} \)

\(\bf \large \implies \: {x}^{2} \: = \:400 \: + \: 2304\)

\(\bf \large \implies \: {x}^{2} \: = \:2704\)

\(\bf \large \implies \: \sqrt{x} \: = \: \sqrt{2704} \)

\(\bf \large \implies \: \: x \: = \: 52\)

Hence , the length of hypotenuse is 52.

its 60 answer C.............

Answer:

102cm²

Step-by-step explanation:

Step 1 find the area of the whole rectangle

Area of a rectangle = width times length

The width of the rectangle is 20 cm and the length is 6cm

So the area = 20 * 6

20 * 6 = 120

Hence the area of the rectangle is 120 square centimeters.

Step 2 Find the area of the square and the triangle

Area of square = s²

where s = side length

The square has a side length of 3 so the area of the square = 3²

3² = 9

Hence, the area of the square is 9cm²

Now to find the area of the triangle

area of a triangle =  where b = base length and h = height

We are given the height (3 cm, this is given because the square is sharing it's side length with the height of the triangle.)

Now to find the base length

We can find it by subtracting the overall rectangle's width (20cm) by the bottom width (11 cm) and the bottom length of the square ( 3 cm )

so triangle's base length = 20 - 11 - 3

20 - 11 - 3 = 6

so the base length of the triangle is 6 cm

now we plug in the values of the height and the base length into the formula

Hence the area of the triangle is 9 cm²

Finally, to find the area of the shaded area, we subtract the area of the triangle and the area of the square from the area of the rectangle

so your answer = 120 - 9 - 9

120 - 9 - 9 = 102

Hence, the area of the shaded region is 102 square centimeters.

As a general rule, we know that the area of a dilated figure is the area of the original figure multiplied by the square of the scale factor. We can see this in the following formula:

where A is the area of the original figure, A' is the area of the dilated figure and k is the scale factor.

In this case, we have that the area of the dilated figure (trapezoid A'B'C') is 12 square units, and the scale factor is k = 2/3. Then, using the equation we get the following:

therefore, the area of trapezoid ABCD is 5 1/3 square units

Haleema would have approximately £3947.46 in her account after 2 years and 11 months, considering the monthly compounding interest of 5%.

To calculate the amount of money in Haleema's account after 2 years and 11 months, we need to consider the monthly compounding interest on the account.

The interest rate is given as 5% per year, which means the monthly interest rate is (5%/12) = 0.4167%.

Let's calculate the final amount using the compound interest formula: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.

In this case, P = £3700, r = 0.004167, n = 12 (monthly compounding), and t = 2.917 (2 years and 11 months).

Plugging these values into the formula, we get:

A = £3700(1 + 0.004167/12)^(12*2.917)

A ≈ £3947.46

The amount of money in Haleema's account after 2 years and 11 months would be approximately £3947.46.

To convert euros to pounds, we have to multiply the amount in euros by the exchange rate. So, the sunglasses cost 90 * 0.875 = 78.75 pounds.

To use a suitable approximation, we can round the exchange rate to the nearest hundredth, which is 0.88. This makes the calculation easier and gives a close estimate of the actual value.

Using the rounded exchange rate, the sunglasses cost 90 * 0.88 = 79.2 pounds.

We can see that both the exact and the approximate values are greater than 70 pounds, so Elyas is wrong. The sunglasses cost more than 70 pounds

Expensive cars draw more attention than cheaper cars is most likely to bias the results.

The capacity of expensive automobiles to provide a smooth ride or to filter out road irregularities so that the occupants may drive in the utmost comfort is typically associated with their plush ride quality.

The underlying engineering, including the suspension design, weight distribution, and wheel size, affects ride quality. The suspension in most low-cost vehicles is built to function well in most conditions.

Handling is the ease with which a vehicle must undergo quick or successive changes in directions without upsetting the driver. Handling depends on the chassis design and suspension design. Usually, handling is inversely proportional to ride quality, as great handling vehicles require a stiffer suspension.

Answer:

Angle 1= 45°

Angle 2= 90°

Step-by-step explanation:

Angle is found when you divide 90 by 2

We do this because all edges of a square add up to 90 and this angle is split in half, which is why we divided by 2

The to find angle 2 you get 45 for the left side of the triangle, 45 on the right side add them, which will give you 90, then subtract from 180 because angles in triangle equals 180 when you do this you get 90.
