The linear function y = 3 · w - 1 represents the number of sea shells found in each week.

The speed of the driven gear is 180 rounds per minute.

In the first problem we have an example of linear progression, in which the number of sea shells is increased linearly every week. After a quick analysis, we conclude that the linear function y = 3 · w - 1, a kind of direct relationship.

In the second problem, we must an inverse relationship to determine the speed of the driven gear. Please notice that the speed of the gear is inversely proportional to the number of teeths. Then, we proceed to calculate the speed:

\(\frac{v_{1}}{v_{2}} = \frac{N_{2}}{N_{1}}\)

If we know that \(v_{2} = 60\,rpm\), \(N_{2} = 60\) and \(N_{1} = 20\), then the speed of the driven gear is:

\(v_{1} = v_{2}\times \frac{N_{2}}{N_{1}}\)

\(v_{1} = 60\,rpm \times \frac{60}{20}\)

\(v_{1} = 180\,rpm\)

The speed of the driven gear is 180 rounds per minute.

We know that the circumference (C) of a circle can be calculated using the formula:

C = 2πr, where r is the radius of the circle.

We are given that the circumference of the circle is 2.20 cm, so we can use this to solve for the radius (r):

C = 2πr

2.20 = 2πr

r = 2.20 / (2π)

r ≈ 0.350 cm

Therefore, the radius of the circle is approximately 0.350 cm.

To find the area (A) of the circle, we can use the formula:

A = πr^2

Substituting the value we found for r:

A = π(0.350)^2

A ≈ 0.385 cm^2

Therefore, the area of the circle is approximately 0.385 cm^2.

The coordinates of vertex D in the parallelogram are (-7, -10).

We have,

To find the coordinates of vertex D of the parallelogram, we need to use the properties of a parallelogram.

One of these properties states that opposite sides of a parallelogram are parallel and have equal lengths.

Given that A = (8, 2), B = (6, -4), and C = (-5, -4), we can find the coordinates of D as follows:

Find the vector representing one of the sides of the parallelogram.

We can use the vector AB.

Vector AB = (x-coordinate of B - x-coordinate of A, y-coordinate of B - y-coordinate of A)

= (6 - 8, -4 - 2)

= (-2, -6)

Add this vector to point C to find the coordinates of D.

Coordinates of D = (x-coordinate of C + x-coordinate of AB, y-coordinate of C + y-coordinate of AB)

= (-5 - 2, -4 - 6)

= (-7, -10)

Therefore,

The coordinates of vertex D are (-7, -10).

The first step in evaluating the expression 3x{9-(4+2)/2 is to simplify the innermost parentheses. By performing operations within parentheses first, we can simplify the expression and make it easier to evaluate.

To begin, we evaluate the expression within the parentheses (4+2), which equals 6. Thus, the original expression becomes 3x{9-6/2}.

The next step is to simplify the division operation. We divide 6 by 2, resulting in 3. Now the expression becomes 3x{9-3}.

The subsequent step is to simplify the subtraction operation. We subtract 3 from 9, giving us 6. The expression now becomes 3x6.

Finally, we multiply 3 by 6, yielding a final result of 18. Therefore, the evaluation of the expression 3x{9-(4+2)/2 is equal to 18.

By simplifying the parentheses, performing the division, and evaluating the subtraction, we systematically reduce the expression to its simplest form. Following the order of operations (also known as PEMDAS or BODMAS), which prioritizes parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right), ensures an accurate evaluation of the expression.

The two equations that have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p include the following:

B. 2.3p – 10.1 = 6.49p – 4

C. 230p – 1010 = 650p – 400 – p

From the information provided, we have the following equation:

2.3p – 10.1 = 6.5p – 4 – 0.01p

Next, we would simplify the given equation by collecting like terms as follows;

2.3p - 10.1 = 6.5p - 0.01p - 4 = 6.49p - 4

2.3p - 10.1 = 6.49p - 4

In Mathematics, the multiplication property of equality states that both sides of an equation will remain the same and equal, when both sides of the equations are multiplied by the same number.

By multiplying both sides of the given equation by 100, we have;

100 × (2.3p - 10.1) = 100 × (6.5p - 4 - 0.01p)

230p - 1010 = 650p - 400 - p

Answer:

\(\displaystyle{x = \dfrac{\ln 5+6 \ln 10}{2\ln 10} }\)

Step-by-step explanation:

We are given the exponential equation of:

\(\displaystyle{10^{2x-6} = 5}\)

Take natural logarithm both sides:

\(\displaystyle{\ln \left(10^{2x-6}\right) = \ln 5}\)

Apply logarithm property where:

\(\displaystyle{\ln M^N = N\ln M}\)

Therefore:

\(\displaystyle{(2x-6)\ln 10 = \ln 5}\)

Divide both sides by \(\displaystyle{\ln 10}\):

\(\displaystyle{\dfrac{(2x-6)\ln 10}{\ln 10} = \dfrac{\ln 5}{\ln 10}}\\\\\displaystyle{2x-6 = \dfrac{\ln 5}{\ln 10}}\)

Add 6 both sides:

\(\displaystyle{2x-6+6 = \dfrac{\ln 5}{\ln 10}+6}\\\\\displaystyle{2x = \dfrac{\ln 5}{\ln 10}+6}\)

Then divide both sides by 2:

\(\displaystyle{\dfrac{2x}{2} = \dfrac{\dfrac{\ln 5}{\ln 10}+6}{2}}\\\\\displaystyle{x = \dfrac{\ln 5}{2\ln 10} + 3}\)

Multiply 3 by 2ln10 for both denominator (1) and numerator (3):

\(\displaystyle{x = \dfrac{\ln 5}{2\ln 10} + \dfrac{3 \cdot 2\ln 10}{1 \cdot 2\ln 10}}\\\\\displaystyle{x = \dfrac{\ln 5}{2\ln 10} + \dfrac{6\ln 10}{ 2\ln 10}}\)

Add in one denominator:

\(\displaystyle{x = \dfrac{\ln 5+6 \ln 10}{2\ln 10} }\)

Hence, the answer is first choice.

Step-by-step explanation:

10^(2x - 6) = 5

i would use immediately a log10 of both sides and get

2x - 6 = log10(5)

since the answers want to use ln, let's convert the log10 term to ln (rules of logarithm - change of base rule) :

log10(5) = ln(5)/ln(10)

so, we have

2x - 6 = ln(5)/ln(10)

then

2x = ln(5)/ln(10) + 6

x = ln(5)/(2ln(10)) + 6/2

and now to bring the whole right side into one fraction, we need to transform 6/2 into something like .../(2ln(10)).

so, we get

x = ln(5)/(2ln(10)) + (6ln(10))/(2ln(10)) =

= (ln(5) + 6ln(10))/(2ln(10))

that is the first answer option.

The answer for this question is Celsius for Fahrenheit.

To convert temperatures from degrees Fahrenheit to degrees Celsius, multiply the result by.5556 (or 5/9) after subtracting 32.

(50°F - 32) x.5556 = 10°C, for instance.

When converting from degrees Celsius to Fahrenheit, multiply the result by 1.8 (or 9/5) and then by 32.

For instance, (30°C x 1.8) + 32 = 86°F'

Here are two useful charts that translate between F and C as well as between C and F.

The temperature of f degrees Fahrenheit converted to degree Celsius.
