6.1/3.9 = 2.8x/x+8.1
solve for x

Answer:

Step-by-step explanation:

Here's a step-by-step explanation to find the three consecutive numbers whose sum is 42:

Let's call the smallest of the three numbers "x".

Since they are consecutive numbers, we can represent the next two numbers as x+1 and x+2.

The sum of these three numbers can be represented as x + (x + 1) + (x + 2) = 42.

Simplifying this equation, we get 3x + 3 = 42.

Subtracting 3 from both sides, we get 3x = 39.

Dividing both sides by 3, we get x = 13.

So, the three consecutive numbers are 13, 14, and 15.

All the pair of angles are congruent except ∠5 and ∠3 are not congruent.

Answer:

4 2/3 ÷ 2 1/6 is equal to 2 2/13.

Step-by-step explanation:

When dividing 2 1/6 from 4 2/3, you will get 2 2/13 or 2.15.

The net force and magnitude is 54°. The solution has been obtained by using trigonometry.

What is trigonometry?

The primary objective of the branch of mathematics known as "trigonometry" is the study of the sides, angles, and connections of the right-angle triangle.

We are given that three forces are acting on the ring.

So,

A = -128 N + 64 N

A = -64 N

[tex]A_{x}[/tex] = A cos θ[tex]_{A}[/tex]

[tex]A_{x}[/tex] = (-64 N) (cos 180°)

[tex]A_{x}[/tex] = -64 N

[tex]A_{y}[/tex] = A sin θ[tex]_{A}[/tex]

[tex]A_{y}[/tex] = (-64 N) (sin 180°)

[tex]A_{y}[/tex] = 0 N

B[tex]_{x}[/tex] = B cos θ[tex]_{B}[/tex]

B[tex]_{x}[/tex] = (128 N) (cos 30°)

B[tex]_{x}[/tex] = 111 N

B[tex]_{y}[/tex] = B sin θ[tex]_{B}[/tex]

B[tex]_{y}[/tex] = (128 N) (sin 30°)

B[tex]_{y}[/tex] = 64 N

R[tex]_{x}[/tex] = A[tex]_{x}[/tex] + B[tex]_{x}[/tex]

R[tex]_{x}[/tex] = -64 N + 111 N

R[tex]_{x}[/tex] = 47 N

R[tex]_{y}[/tex] = A[tex]_{y}[/tex] + B[tex]_{y}[/tex]

R[tex]_{y}[/tex] = 0 N + 64 N

R[tex]_{y}[/tex] = 64 N

[tex]R = \sqrt{R_{x}^{2} +R_{y}^{2} }[/tex]

[tex]R = \sqrt{(47 N)^{2} +(64 N)^{2} }[/tex]

R = 79 N

θ = [tex]tan^{-1}(\frac{R_{y} }{R_{x}} )[/tex]

θ = [tex]tan^{-1}(\frac{64 }{47} )[/tex]

θ = 54°

Hence, the net force and magnitude is 54°.

Fundamental Theorem of Calculus made a precise connection between the indefinite and definite integrals by stating that the derivative of the definite integral of a function is equal to the original function.

The Fundamental Theorem of Calculus is a key result in mathematics that connects two branches of calculus - the definite integral and the indefinite integral.

The definite integral is used to calculate the total area under a curve. It is defined as the limit of the sum of rectangles with increasing precision, as the width of each rectangle approaches zero.

The definite integral can be calculated using definite limits, for example, from x = 0 to x = 1, and the result is a definite number.

The indefinite integral, on the other hand, is a function that, when differentiated, will give us the original function.

The Fundamental Theorem of Calculus if we have a definite integral of a function f(x) from a to b, then the derivative of this definite integral will be equal to

=> f(x) at x = b - f(x) at x = a.

This provides us with a precise way of calculating areas under curves, and it has many practical applications in fields such as physics, engineering, and economics.

The exponential function for the graph is obtained as y = 3^x.

What is an exponential function?

The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

Assume that the plot of a function is in the form -

y =ab^x

where the horizontal asymptote is the x-axis.

To find a, look for the coordinate where the curve crosses the y-axis.

In the plot, it is seen that this happens at (0,1).

So, the value of a = 1.

To find b, look for the coordinate where the curve crosses the vertical line at x = 1.

In the plot, it is seen that this happens at (1,3).

Then, b is the number divided by a -

b = 3/1 = 3.

This plot is the curve -

y = 3^x

Therefore, the exponential function is y = 3^x.

Answer:

m = 50kg

Step-by-step explanation:

First, you  have to know that mass is an indicator of the amount of matter that makes up a body. Its unit in the International System is the kilogram (kg).

The mass of an object will always be the same, no matter where it is located.

On the other side, bodies are subjected to the action of forces, such as the force of gravity or electromagnetic forces.

So, weight is the action exerted by the force of gravity on the body. That is, weight is a measure of how much force gravity exerts on the mass of an object.

The weight of an object is measured in Newton (N) and will vary according to the force of gravity that acts on it.

The expression for the calculation of the weight is:

P= m×g

where:

In this case, you know that:

P= 980 N

m= ?

g= 19.6 [tex]\frac{m}{s^{2} }[/tex]

Replacing in the expression for the calculation of the weight:

980 N= m× 19.6 [tex]\frac{m}{s^{2} }[/tex]

Solving:

[tex]\frac{980N}{19.6\frac{m}{s^{2} } }[/tex]

m=50 kg

The difference between amount of  two proportions is measured by D'.

D' is a metric for comparing differences between two proportions. It serves as a gauge for comparing how far apart the two proportions are from one another. It is determined by multiplying the difference between the two proportions by the sum of the standard deviations of the two proportions. The outcome is a measurement of how many standard deviations there are between the two proportions.

In statistical tests like the Chi-Square test or the Z-test, D' is most frequently employed to calculate the difference between two proportions. It is a helpful way to compare two proportions because it indicates whether or not the difference is statistically significant. Given that it takes into consideration the variability of each sample, it is especially helpful when comparing two proportions when the sample sizes are different. In data-mining applications, where it can be used to find correlations between two proportions, D' is also a helpful measure of the separation between two proportions.

True, The span of {u, v} contains both the line through u and the origin, as well as the line through v and the origin.

The span of a set of vectors is defined as the set of all linear combinations of those vectors. When u and v are nonzero vectors, the span of {u, v} is a two-dimensional subspace of the vector space that contains both u and v, and any linear combination of u and v.

Since u and v are nonzero vectors, the lines through the origin and u, and through the origin and v, are non-degenerate lines in the vector space. Therefore, these lines are contained within the span of {u, v}.

In other words, if we take any scalar multiples of u and v, such as au and bv, where a and b are scalars, the sum au + bv will be a linear combination of u and v and therefore will also be contained within the span of {u, v}.

Therefore, the span of {u, v} contains both the line through u and the origin, as well as the line through v and the origin.
