The approximate diameter of this circle is equal to 11.0 in.

Given the following data:

To determine the approximate diameter of this circle:

Mathematically, the circumference of a circle is given by the formula:

[tex]Circumference = \pi D[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]35\frac{13}{21}=\frac{22}{7} D\\\\\frac{748}{21} =\frac{22D}{7} \\\\748\times 7=22D \times 21\\\\5236=462D\\\\D=\frac{5236}{462}[/tex]

D = 11.3 ≈ 11.0 in.

Answer:

x = 17

Step-by-step explanation:

5x - 18 and 4x + 45 are adjacent angles on as straight line and sum to 180° , so

5x - 18 + 4x + 45 = 180 , that is

9x + 27 = 180 ( subtract 27 from both sides )

9x = 153 ( divide both sides by 9 )

x = 17

Answer: Velocity is a vector, so it has a magnitude and direction.

Speed is its magnitude, which is obtained from

|〈-3, 4〉 m/s| = √((-3 m/s)² + (4 m/s)²) = √(25 m²/s²) = 5 m/s

Its direction is an angle θ made with the positive horizontal axis, satisfying

tan(θ) = (4 m/s) / (-3 m/s) = -4/3   →   θ = arctan(-4/3) + 180°n

where n is any integer. Now you have to consider that the x coordinate is negative and the y coordinate is positive, so 〈-3, 4〉 points into the second quadrant, and we get an angle there for n = 1 of about

θ ≈ 126.87°

Alternatively, you can use the vector 〈1, 0〉 in place of the axis, then compute the angle by relating it to the dot product, so θ is such that

〈-3, 4〉 • 〈1, 0〉 = |〈-3, 4〉| |〈1, 0〉| cos(θ)

(-3)•1 + 4•0 = √((-3)² + 4²) • √(1² + 0²) cos(θ)

-3/5 = cos(θ)   →   θ = arccos(-3/5) + 360°n

where again, n is any integer, and we get the same solution θ ≈ 126.87° in the second quadrant when n = 0.

Solution:

Note that:

Simplify the LHS, then use cross multiplication to solve for n.

Answer:

n = 15

Step-by-step explanation:

Step-by-step explanation:

Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. The correct option is D, 38 millon.

Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.

It is given by the formula,

A = P(1+r)ⁿ

where, A is the value after n period of time, P is the initial amount, and,

r is the rate of increment or decrement.

Given that On the first day of a song's release, it had 20 million streams. Also, the number of streams increases by 10% per day. Therefore, it can be said that the number of streams is compounding. Thus, the number of streams on the seventh day will be,

Number of streams = 20 (1+0.10)⁷ million

                                 = 20 × 1.9487 million

                                 = 38.974 million

                                 = 38 million

Hence, the number of streams there will be on the seventh day is 38 million.

Answer:

c = 2

Step-by-step explanation:

2c – 4 = 3(4 – 2c)

Expand brackets:

⇒ 2c – 4 = 12 - 6c

Add 6c to both sides:

⇒ 8c – 4 = 12

Add 4 to both sides:

⇒ 8c = 16

Divide both sides by 8:

⇒ c = 2

Answer:

c = 2

Step-by-step explanation:

First expand 3(4-2c):

3×4=12

3×-2c=-6c

Now our equation is :

2c-4 = 12-6c

Add 4 to both sides:

2c-4+4=12-6c+4

Simplify:

2c = -6c+16

Add 6c to both sides:

2c+6c = -6c+16+16

Simplify:

8c=16

Divide both sides by 8:

8c÷8 = 16÷8

c = 2

Answer:

I think the answer is D

Step-by-step explanation:

A correct conclusion that can be reached is that: D) The Vikings averaged more points at home games, but were more consistent when playing on the road.

An arithmetic average is also referred to as mean and it can be defined as a ratio of the sum of the total number in a data set (population) to the frequency of the data set.

This ultimately implies that, an average score is a mean score and it can be calculated by dividing the total number of scores obtained by the total number of Vikings players.

In conclusion, we can reasonably infer and logically deduce that Walker Vikings were more consistent when playing on the road, but averaged more points at home games.

The circulation of V around the given path (call it C) is simply the line integral of V along C. Since C is a closed curve, we can use Green's theorem.

[tex]\displaystyle \int_C \vec V(x,y) \cdot d\vec r = \iint_{\mathrm{int}(C)} \frac{\partial}{\partial x}\left[\frac{x+1}{(x+1)^2+4y^2}\right] - \frac{\partial}{\partial y}\left[-\frac{y}{(x+1)^2+4y^2}\right] \, dx\,dy[/tex]

where int(C) is the interior or region bounded by C.

We have

[tex]\dfrac{\partial}{\partial x}\left[\dfrac{x+1}{(x+1)^2+4y^2}\right] = \dfrac{4y^2 - (x+1)^2}{((x+1)^2+4y^2)^2}[/tex]

[tex]\dfrac{\partial}{\partial y}\left[-\dfrac{y}{(x+1)^2+4y^2}\right] = \dfrac{4y^2-(x+1)^2}{((x+1)^2+4y^2)^2}[/tex]

so the double integral and hence the circulation is zero.

divide by 9 by 9         x-11 = 1

add 11 to 1      x= 12

Pretty much you take a value on the left and do the opposite of what its doing and then do it to the number on the right. since 9 was going to multiply on the left, then you would divide it on the right
