The 875 times smaller is 4 x 10−7 than 3.5 x 10−4.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given the two quantities 4 x 10−7 and 3.5 x 10−4

Now, if we divide this then

⇒ (3.5 x 10−4)/(4 x 10−7)

⇒ (35/40) × 10³

⇒ 875

Hence "The 875 times smaller is 4 x 10−7 than 3.5 x 10−4".

Answer:

8 x 7

Step-by-step explanation:

The new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees are approximately (4.993, 2.048).

To find the new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees, we can use the rotation formula:

x' = x * cos(theta) - y * sin(theta)

y' = x * sin(theta) + y * cos(theta)

Where (x, y) are the original coordinates, (x', y') are the new coordinates after rotation, and theta is the angle of rotation in radians.

Converting the angle of rotation from degrees to radians:

theta = 5 degrees * (pi/180) ≈ 0.08727 radians

Plugging in the values into the rotation formula:

x' = 5 * cos(0.08727) - 2 * sin(0.08727)

y' = 5 * sin(0.08727) + 2 * cos(0.08727)

Evaluating the trigonometric functions and simplifying:

x' ≈ 4.993

y' ≈ 2.048

Step-by-step explanation:

Alternate exterior angles are congruent, thus

∠ RST = ∠ RQP , substitute values

7x + 11 = 4x + 32 ( subtract 4x from both sides )

3x + 11 = 32 ( subtract 11 from both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Thus

∠ RST = 7(7) + 11 = 49 + 11 = 60°

∠ RQP = 4(7) + 32 = 28 + 32 = 60°

Answer:

34, and if 55 was replaced with 33, the new median would be 33.

Step-by-step explanation:

The median is the number that is in the middle of a data set, once the numbers are organized from least to greatest. If we put the numbers in order (18, 22, 24, 32, 34, 39, 55, 57, 59), the number in the middle is 34. If we do the same, but replace 55 with 33, (18, 22, 24, 32, 33, 34, 39, 57, 59), we get 33 as the median.

1. The number of computations (hashes) required for finding a collision at 80% and 10% probabilities is 1.8447 x 10^19.

2. It will take approximately 47,891 seconds (or 13.3 hours) to find a collision at 10% probability.

The number of computations (hashes) required for finding a collision at 80% and 10% probabilities depends on the size of the hash function output. Let's assume a hash function output size of 128 bits for this example.

For finding a collision at 80% probability, we need to use the birthday attack algorithm. The number of hashes required can be calculated using the following formula:

N = sqrt((2^(n+1))*ln(1/(1-p)))

where n is the size of the hash output in bits (n=128 in this case), p is the desired probability of finding a collision (p=0.8 in this case), ln is the natural logarithm, and sqrt is the square root function.

Substituting the values, we get:

N = sqrt((2^(128+1))*ln(1/(1-0.8))) = 2^64.3155 = 1.8447 x 10^19

Therefore, we need 1.8447 x 10^19 hashes to find a collision at 80% probability.

For finding a collision at 10% probability, we can use the following formula:

N = sqrt((2^(n+1))*ln(1/(1-p)))

Substituting the values, we get:

N = sqrt((2^(128+1))*ln(1/(1-0.1))) = 2^55.9724 = 4.7891 x 10^16

Therefore, we need 4.7891 x 10^16 hashes to find a collision at 10% probability.

If we have a computer that can process a trillion hashes per second, we can calculate the time required to find a collision at 10% probability as follows:

time = N / rate

where N is the number of hashes required to find a collision (N=4.7891 x 10^16), and rate is the rate of hashes that the computer can process per second (rate=1 trillion = 1 x 10^12).

Substituting the values, we get:

time = (4.7891 x 10^16) / (1 x 10^12) = 4.7891 x 10^4 seconds

Therefore, it will take approximately 47,891 seconds (or 13.3 hours) to find a collision at 10% probability with a computer that can process a trillion hashes per second.

The coordinate of a point that divides a line AB in a ratio a:b from A(\(x_1,y_1\)) to B(\(x_2,y_2\)) is given by the formula:

\((x,y)=(\frac{bx_1+ax_2}{a+b} ,\frac{by_1+ay_2}{a+b} )=(\frac{a}{a+b}(x_2-x_1)+x_1 ,\frac{a}{a+b}(y_2-y_1)+y_1 )\)

Given that a line JK, with  Point J is at ( -6, - 2) and point K is at point (8, - 9) into a ratio of 2:5. The x coordinate is given as:

\(x=\frac{2}{2+5} (8-(-6))+(-6)=\frac{2}{7}(14) -6=4-6=-2\)

Line segments can be divided into equal or unequal ratios

The x coordinate of the segment is -2

The coordinates of points J and K are given as:

\(J = (-6,-2)\)

\(K = (8,-9)\)

The ratio is given as:

\(m : n =2 : 5\)

The x-coordinate is then calculated using:

\(x = (\frac{m}{m + n }) (x_2 - x_1) + x_1\)

So, we have:

\(x = (\frac{2}{2 + 5 }) (8 - -6) -6\)

\(x = (\frac{2}{7}) (14) -6\)

Expand

\(x = (2) (2) -6\)

Open bracket

\(x = 4 -6\)

Subtract 6 from 4

\(x = -2\)

The estimated value of f(b) using linear approximation is -24.44, and the error in the approximation is approximately 24.54.

Given, f(x) = 1/x^(1/2)We have to use linear approximation to estimate δf for a change in x from x = a to x = b, and then use the estimate to approximate f(b), and find the error using the calculator

.To find the δf using the linear approximation, we have to first find the first derivative of the function and then use it in the formula.

Differentiating f(x) w.r.t x, we get:f'(x) = -1/2x^(3/2)

Now, using the formula for linear approximation, we have:δf ≈ f'(a) * δxδx = b - a

Now, substituting the values, we get:δf ≈ f'(a) * δxδx = b - a = 107 - 100 = 7Thus,δf ≈ f'(100) * 7f'(100) = -1/2 * 100^(3/2)δf ≈ -35 * 7δf ≈ -245

To approximate f(b), we have:f(b) ≈ f(a) + δff(a) = f(100) = 1/100^(1/2)f(b) ≈ f(a) + δf = 1/100^(1/2) - 245 ≈ -24.44

To find the error, we can use the actual value of f(b) and the estimated value of f(b) that we found above:

Actual value of f(b) is:f(107) = 1/107^(1/2) ≈ 0.0948Thus, the error is given by: Error = |f(b) - Approximation|Error = |0.0948 - (-24.44)| ≈ 24.54

Answer:

Step-by-step explanation:

The future value of the $10,000 investment after 7 years, at an interest rate of 6% per year, compounded annually, is approximately $14,185.10.

To calculate the future value (FV) of an investment of $10,000 at an interest rate of 6% per year, compounded annually, after 7 years, we can use the formula:

FV = P(1 + r)^n

Where:

P is the principal amount (initial investment) = $10,000

r is the interest rate per period = 6% = 0.06

n is the number of periods = 7

Plugging in the values, we have:

FV = $10,000(1 + 0.06)^7

Calculating the expression inside the parentheses first:

(1 + 0.06)^7 ≈ 1.41851

Now, multiply the principal amount by the calculated expression:

FV ≈ $10,000 * 1.41851 ≈ $14,185.10

Therefore, the future value of the $10,000 investment after 7 years, at an interest rate of 6% per year, compounded annually, is approximately $14,185.10.

F is continuous at every point x₀ ∈ I. Thus, f is continuous on an interval I.

Regarding the converse, the statement "if f is continuous on an interval I, then it is uniformly continuous on I" is not always true. There exist functions that are continuous on a closed interval but not uniformly continuous on that interval. A classic example is the function f(x) = x² on the interval [0, ∞). This function is continuous on the interval but not uniformly continuous.

To prove that if a function f is uniformly continuous on interval I, then it is continuous on I, we need to show that for any ε > 0, there exists a δ > 0 such that for any x, y ∈ I, if |x - y| < δ, then |f(x) - f(y)| < ε.

Since f is uniformly continuous on I, for the given ε, there exists a δ > 0 such that for any x, y ∈ I, if |x - y| < δ, then |f(x) - f(y)| < ε.

Now, let's consider an arbitrary point x₀ ∈ I and let ε > 0 be given. Since f is uniformly continuous, there exists a δ > 0 such that for any x, y ∈ I, if |x - y| < δ, then |f(x) - f(y)| < ε.

Now, choose δ' = δ/2. For any y ∈ I such that |x₀ - y| < δ', we have |f(x₀) - f(y)| < ε.

Therefore, for any x₀ ∈ I and ε > 0, we can find a δ' > 0 such that for any y ∈ I, if |x₀ - y| < δ', then |f(x₀) - f(y)| < ε.

This shows that f is continuous at every point x₀ ∈ I. Thus, f is continuous on interval I.
