The length of the chord located 0.7 cm from the centre of a circular ring with a 2.5 cm radius is approximately 3.5 cm.

To calculate the length of the chord, we can use the following formula:

Chord Length = 2 x √(r^2 - d^2)

Where r is the radius of the circular ring and d is the distance between the chord and the centre of the circle.

In this case, r = 2.5 cm and d = 0.7 cm. Plugging these values into the formula, we get:

Chord Length = 2 x √(2.5^2 - 0.7^2) ≈ 3.5 cm (rounded to the nearest tenth)

Therefore, the length of the chord is approximately 3.5 cm. This hidden watermark technique is a simple but effective security measure that can help prevent counterfeiting or tampering with important documents. By incorporating a unique and difficult-to-replicate watermark, the jewellery company can protect its brand identity and ensure the authenticity of its official documents.

The solutions to the equation -30x² + 9x + 60 = 0 are x = 5/2 and x = -4/5.

To solve the equation, we can start by bringing all the terms to one side to have a quadratic equation equal to zero. Let's go step by step:

-5/3 x² + 3x + 11 = -9 + 25/3 x²

First, let's simplify the equation by multiplying each term by 3 to eliminate the fractions:

-5x² + 9x + 33 = -27 + 25x²

Next, let's combine like terms:

-5x² - 25x² + 9x + 33 = -27

-30x² + 9x + 33 = -27

Now, let's bring all the terms to one side to have a quadratic equation equal to zero:

-30x² + 9x + 33 + 27 = 0

-30x² + 9x + 60 = 0

Finally, we have the quadratic equation in standard form:

-30x² + 9x + 60 = 0

Dividing each term by 3, we get:

-10x² + 3x + 20 = 0

(-2x + 5)(5x + 4) = -10x² + 3x + 20

So, the factored form of the equation -30x² + 9x + 60 = 0 is:

(-2x + 5)(5x + 4) = 0

Now we can set each factor equal to zero and solve for x:

-2x + 5 = 0 --> x = 5/2

5x + 4 = 0 --> x = -4/5

Answer:

x=12

Step-by-step explanation:

LM = RS

9x+27 = 135

Subtract 27 from each side

9x+27-27 =135-27

9x=108

Divide each side by 9

9x/9 = 108/9

x = 12

the boxes are equivalent so the one with a single dash is equal to the other with a single dash.

the one with 2 dashes is equal to the other with 2 dashes so on and so forth

SR=LM

LM=9x+27

RS=135

9x+27=135

Given that a circle with radius 20 has a corresponding angle of 305°.

To find the coordinates of a point on the circle, we use the formula:`(r cos (θ), r sin (θ))`Here, `r = 20` and `θ = 305°`.

Substituting the values of `r` and `θ` in the formula, we get:`(20 cos (305°), 20 sin (305°))`

Using the values of trigonometric ratios, we can write:cos(305°) = cos(360° - 305°) = cos(55°) ≈ -0.5736sin(305°) = sin(360° - 305°) = sin(55°) ≈ 0.8192

Hence, the coordinates of a point on a circle with radius 20 corresponding to an angle of 305° are approximately `(-11.47, 16.38)`.

In Mathematics and Financial accounting, continuous compounding interest can be determined or calculated by using this mathematical equation (formula):

\(A(t) = P_{0}e^{rt}\)

Where:

Part a.

Based on an exponential growth rate of 3.8% in the first area, the cost of this home in t years can be written as follows;

\(A(t) = P_{0}e^{rt}\\\\C_1 = 250000e^{0.038t}\)

The limit is 0.

We will first understand what limit is and ten calculate it :

A limit is a boundary beyond which something may not extend. Limit has many meanings such as "the point at which something stops", or "a boundary". It can also mean "to restrict" or "restrict".

We can use the word "limit" to describe what we don't want, but if it is to get used with time-sensitive items we have to make sure it's accurate.

To evaluate the limit, we can use L'Hopital's rule since we have an indeterminate form of "infinity/infinity". Differentiating the numerator and denominator with respect to x, we get:

lim x→[infinity] 7 - x / 7(2ex) = lim x→[infinity] (-1) / (14ex)

Since the denominator goes to infinity as x goes to infinity, and the numerator remains constant, we can see that the limit is equal to zero:

lim x→[infinity] 7 - x / 7(2ex) = lim x→[infinity] (-1) / (14ex) = 0

Answer:

The derivative of infinity is undefined. Infinity is not a number, but rather a concept that represents a quantity that is unbounded or limitless. The derivative of a function at a point is a measure of the rate of change of the function at that point. Since infinity itself does not have a numerical value or a well-defined location, it is not possible to take the derivative of infinity. This means that the concept of the derivative does not apply to infinity and the derivative of infinity is undefined.

The required, in 2007 the price per gallon was 7b more than the price of a gallon of fuel in the year 2000. Where b is the inflation factor.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let 'a' be the cost per gallon of fuel in the year 2000, and 'b' be the inflation rate per year. If the rate of inflation is constant then
After 7 year inflation = 7b
Cost of fuel in 2007 = a + 7b

Ted can clear a football field in 3 hours, while Jacob can clear it in 2 hours. When they work together, the time it takes to clear the field can be determined by solving the equation 1/3 + 1/2 = 1/t.

Let's consider the equation 1/3 + 1/2 = 1/t, where t represents the number of hours it would take Ted and Jacob to clear the field together. To solve for t, we need to find a common denominator for the fractions on the left-hand side. The least common multiple (LCM) of 3 and 2 is 6.

By multiplying the first fraction by 2/2 and the second fraction by 3/3, we can rewrite the equation as (2/6) + (3/6) = 1/t. This simplifies to 5/6 = 1/t.

To isolate t, we can take the reciprocal of both sides, giving us t/1 = 6/5. Cross-multiplying, we find t = 6/5 = 1.2.

Therefore, it will take Ted and Jacob 1.2 hours (or 1 hour and 12 minutes) to clear the football field together.

∫[0,b] f(y) dy = ∫[0,b] b/y^2 dy = [-b/y]0^b = 1

To show that f(y) is a density function, we need to show that it satisfies two conditions:

f(y) is non-negative for all y.

The integral of f(y) over its entire domain is equal to 1.

For the first condition, we can see that f(y) is non-negative for all y, since the numerator and denominator of the expression b/y^2 are both non-negative for y > 0. For y ≤ 0, f(y) is defined to be zero, which is also non-negative.

For the second condition, we need to integrate f(y) over its entire domain. Since f(y) is only defined for y ≤ b, we can integrate from 0 to b to cover the entire domain:

∫[0,b] f(y) dy = ∫[0,b] b/y^2 dy = [-b/y]0^b = 1

Therefore, f(y) is a valid probability density function.

F(y) = ∫[0,y] f(t) dt = ∫[0,y] b/t^2 dt = [-b/t]0^y = 1 - b/y.

To find F(y), we need to integrate f(y) from 0 to y:

F(y) = ∫[0,y] f(t) dt = ∫[0,y] b/t^2 dt = [-b/t]0^y = 1 - b/y

P(Y > b+c) = ∫[b+c,∞) f(y) dy = ∫[b+c,∞) b/y^2 dy = [b/y]b+c^∞ = b/(b+c).

P(Y > b+c) is the probability that a mouse takes longer than b+c seconds to get through the maze. We can calculate this probability by integrating f(y) from b+c to infinity:

P(Y > b+c) = ∫[b+c,∞) f(y) dy = ∫[b+c,∞) b/y^2 dy = [b/y]b+c^∞ = b/(b+c)

P(Y > b+d and Y > b+c) = P(Y > b+d).

P(Y > b+d | Y > b+c) is the probability that a mouse takes longer than b+d seconds to get through the maze, given that it already took longer than b+c seconds. This is a conditional probability, which we can calculate using the formula:

P(Y > b+d | Y > b+c) = P(Y > b+d and Y > b+c) / P(Y > b+c)

The numerator of this expression is the probability that a mouse takes longer than both b+d seconds and b+c seconds to get through the maze. Since b+d > b+c, this probability is simply the probability that the mouse takes longer than b+d seconds:

P(Y > b+d and Y > b+c) = P(Y > b+d)

We can calculate this probability by integrating f(y) from b+d to infinity:

P(Y > b+d) = ∫[b+d,∞) f(y) dy = ∫[b+d,∞) b/y^2 dy = [b/y]b+d^∞ = b/(b+d)

Substituting this into the conditional probability formula, we get:

P(Y > b+d | Y > b+c) = P(Y > b+d) / P(Y > b+c) = (b/(b+d)) / (b/(b+c)) = (b+c)/(b+d).

We can expect that 7935 parts would fail to meet a minimum specification limit of 35 lb tensile strength and 2740 parts would have a tensile strength over 48 lb.

We can use the standard normal distribution to solve this problem.

The standard normal distribution has a mean of 0 and a standard deviation of 1. We can convert the normal distribution of the tensile strength to the standard normal distribution using the formula below.z = (x - μ) / σwhere x is the tensile strength, μ is the mean, and σ is the standard deviation.

a) To determine the number of parts that are expected to fail to meet a minimum specification limit of 35 lb tensile strength, we need to find the probability that a part has a tensile strength less than 35 lb. z = (35 - 40) / 5 = -1P(z < -1) = 0.1587

The probability of a part having a tensile strength of less than 35 lb is 0.1587. Therefore, the number of parts expected to fail to meet a minimum specification limit of 35 lb tensile strength is given by: Number of parts = Probability × Total number of parts= 0.1587 × 50,000= 7935b)

(b) To determine the number of parts that have a tensile strength over 48 lb, we need to find the probability that a part has a tensile strength greater than 48 lb. z = (48 - 40) / 5 = 1.6P(z > 1.6) = 0.0548

The probability of a part having a tensile strength greater than 48 lb is 0.0548. Therefore, the number of parts that have a tensile strength over 48 lb is given by: Number of parts = Probability × Total number of parts= 0.0548 × 50,000= 2740

Therefore, we can expect that 7935 parts would fail to meet a minimum specification limit of 35 lb tensile strength and 2740 parts would have a tensile strength over 48 lb.

The standard deviation of the number in full-time employment is approximately 4.04. The approximate probability that fewer than half of the sample are in full-time employment is 0.0175, or 1.75%.

To find the expected number of people in full-time employment in a sample of 80, we first multiply the sample size by the population proportion: 80 x 0.55 = 44. So, we can expect approximately 44 people in the sample to be in full-time employment.

To find the standard deviation of the number in full-time employment, we use the formula for the standard deviation of a binomial distribution:

σ = √(n x p x q),

where n is the sample size, p is the population proportion, and q is the complement of p (i.e., 1 - p).

Plugging in the values, we get:

σ = √(80 x 0.55 x 0.45) = 4.04

Therefore, the standard deviation of the number in full-time employment is approximately 4.04.

To find the probability that fewer than half of the sample are in full-time employment, we use the binomial distribution again. The probability of getting fewer than half of the sample in full-time employment is the same as the probability of getting 39 or fewer people in full-time employment (since half of 80 is 40).

Using a binomial calculator, we find that the probability of getting 39 or fewer people in full-time employment is 0.0175, or 1.75%.

Therefore, the approximate probability that fewer than half of the sample are in full-time employment is 0.0175, or 1.75%
