The volume of the log will be 30,70,760 m³.

Mathematically, we can write Archimedes principle as -

F{buoyant} = - fluid density {ρ} x acceleration due to gravity {g} x volume {v}

Given is that a 3080 kg log of wood with a diameter of 1 m and 10 m long, it floats in the water.

Since the log floats on water, the density of both the log and water is same.

So, we can write volume as -

Volume = 3080 x 997 Volume = 30,70,760 m³

Therefore, the volume of the log will be 30,70,760 m³.

What is isosceles triangle?

An isosceles triangle is one that has two sides of equal length.

The angles opposite to equal sides are equal.

AB=x+17 units

BC=2x-6 units

We were given that the triangle is an isosceles triangle.

This means that these two sides are equal.

We therefore form the equation below and solve for the value of x.

x+17 = 2x-6

x-2x= -6-17

x=23

We substitute this value into the expression for side BC to get ,

BC=2(23)-6

The inequality relation  -q > -7  can be represented in the form of q as q < 7

The numbers in set A = { -8 , -7.1 , -7 , -6.9 , -6 , -2 , 0 , 2 , 6 , 6.9 }

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be A

The value of A is - q > - 7

Now , multiplying by (-1) on both sides of the equation , we get

( -1 ) ( -q ) > ( -1 ) ( - 7 )

The inequality relation will change the sign from > to < and ,

q < 7

So , the value of the inequality relation A is q < 7

Now , all the values in the number line which satisfy the inequality equation q < 7 are given in set A

The numbers in set A = { -8 , -7.1 , -7 , -6.9 , -6 , -2 , 0 , 2 , 6 , 6.9 }

Hence , The inequality relation  -q > -7  can be represented in the form of q as q < 7 and numbers in set A = { -8 , -7.1 , -7 , -6.9 , -6 , -2 , 0 , 2 , 6 , 6.9 }

Answer:

x=4

y=3

im 100% sure

Answer:

x = 4

y = 3

Step-by-step explanation:

First, reorder the first equation to make it into the same format as the second equation:

y = 2x - 5

-2x + y = -5

Then, put the equations together:

-2x + y = -5

x + y = 7

Solve by elimination by multiplying the bottom equation by 2, then add the equations together and solve for y:

-2x + y = -5

2x + 2y = 14

3y = 9

y = 3

Then, plug in 3 as y into one of the equations to solve for x:

y = 2x - 5

3 = 2x - 5

8 = 2x

4 = x

So, the answer is x = 4 and y = 3

The value of the cash flows four years from today is $22,609.26.

The value of a set of cash flows can be calculated using the present value of an annuity formula. This formula takes into account the time value of money, which states that money has a different value at different points in time due to the opportunity cost of the money. In other words, the money you have today is more valuable than the money you will have in the future.

The present value of an annuity formula is PV = CF / (1 + r)^n, where PV is the present value, CF is the cash flow, r is the interest rate, and n is the number of periods. In this example, the cash flows are $3,000, $4,040, $5,885, and $7,975, the interest rate is 5.4%, and the number of periods is 4. Plugging these numbers into the formula, the present value is $22,609.26. This is the value of the cash flows four years from today.

The value of the cash flows four years from today is $22,609.26.

Answer:

The answer is "Sample size is important when the population is not normally distributed ".

Step-by-step explanation:

The theorem for the central limit indicates that perhaps the sample distribution of means by the sample is close to the confidence interval independent of the underlying population demographics when large samples are derived from every population, with \(mean = \mu\) and confidence interval \((S.D) = \sigma\). The bigger the sample, the stronger the approach (typically \(n \geq 30\)). The sample is therefore significant unless the population is not typically spread.

x = 155

Step-by-step explanation:

0.0395 m, -0.486 ms⁻¹ and -4725.791 ms⁻² are the position, velocity and acceleration of the particle are  respectively

Given that:

A particle moves so that position in meters is given as a function of time in seconds by the equation x(t)=Acos(wt+l), where A=0.0395 m, w=346 s⁻¹, and l=1.00

The position of the particle at 3.00 ms

Substitute t = 3.00 ms = 0.003 s into the function:

x(t) = Acos(wt+l)

x(0.003) = 0.0395cos(346×0.003 + 1.00)

x(0.003) = 0.0395cos(2.039)

x(0.003) = 0.0395 m

The velocity of the particle at 3.00 ms

To get the velocity function, take the derivative of x(t) = Acos(wt+l):

x'(t) = -Awsin(wt+l)

Then substitute t = 3.00 ms = 0.003 s into the velocity function:

x'(t) = -Awsin(wt+l)

x'(0.003) = -0.0395 ×346sin(346×0.003 + 1.00)

x'(0.003) = -13.667sin(2.038)

x'(0.003) = -0.486 ms⁻¹

The acceleration of the particle at 3.00 ms

To get the acceleration function, take the derivative of x'(t) = -Awsin(wt+l):

x''(t) = -Aw²cos(wt+l)

Then substitute t = 3.00 ms = 0.003 s into the  function:

x''(t) = -Aw²cos(wt+l)

x''(0.003) = -0.0395 ×346² cos(346×0.003 + 1.00)

x''(0.003) = -4728.782 cos(2.038)

x''(0.003) = -4725.791 ms⁻²

Therefore, the position, velocity and acceleration of the particle are 0.0395 m, -0.486 ms⁻¹ and -4725.791 ms⁻² respectively

Step-by-step explanation:

First, I'm not sur if you learned it, but do PEMDAS (Parentheses, then exponents, then multiplication, then division, then adding, the. subtracting.) So, 2x4 is first, that's 8. Then, 2x2, that's 4.

An expression is a mathematical sentence that may or may not have an equal sign, whereas an equation is a declaration that two expressions are equal. The equal sign in an equation indicates whether the result is true or false, depending on the values of the variables. On the other hand, while expressions can be assessed or sped up, they cannot be true or untrue. Expressions are used to represent quantities or operations, whereas equations are used to find the values of variables that the equation requires.

For the given expressions simplifying we get:

1. 2/3 (3/4 x - 3/2)

= 1/2 x - 1

This expression is equivalent to x - 1/2.

2. (2x + 1) - (x + 3/2)

The required image T of triangle ABC under the transformation (x,y) → (x-4, y+1) is formed by connecting the vertices A'(a-4, b+1), B'(c-4, d+1), and C'(e-4, f+1)

To find the image T of triangle ABC under the transformation (x,y) → (x-4, y+1), apply this transformation to each of the vertices of triangle ABC and then connect the new vertices to form the image T.

Let's assume that the coordinates of the vertices of triangle ABC are A(a,b), B(c,d), and C(e,f).

To find the image of vertex A under the transformation, we substitute x = a and y = b into the transformation equation:

(x,y) → (x-4, y+1)

(a,b) → (a-4, b+1)

Therefore, the image of vertex A is A'(a-4, b+1).

Similarly, we can find the images of vertices B and C:

B'(c-4, d+1)

C'(e-4, f+1)

Therefore, the image T of triangle ABC under the transformation (x,y) → (x-4, y+1) is formed by connecting the vertices A'(a-4, b+1), B'(c-4, d+1), and C'(e-4, f+1)
