The sum of a geometric series with a first term of 3 and a common ratio of 10/9 is;

∑ [tex]3 (\frac{10}{9} )^k^-^1[/tex]  where, K = 1 to n.

What is Geometric series?

A geometric series is a list of numbers having a common ratio. Each term after the first is gotten by multiplying the previous one by the common ratio.

Given that;

The first term is 3 and the common ratio is 10/9.

Now, A geometric sequence has the form:

a, ar , ar², ar³, . . .

Hence, The nth term of a geometric sequence is;

⇒ ∑ [tex](ar^k^-^1)[/tex]     where, k = 1 to n.

Therefore, the sum of geometric series with a first term of 3 and a common ratio of 10/9 is:

⇒ ∑ [tex]3 (\frac{10}{9} )^k^-^1[/tex]  where, k = 1 to n.

So, The sum of a geometric series with a first term of 3 and a common ratio of 10/9 is;

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

Triangle ABC is dilated with a scale factor of 3. Then the scale factor will be 3.

If the side BC is 5.4 units long, then the length of the side B'C' will be

B'C' = 3 x BC

B'C' = 3 x 5.4

B'C' = 16.2 units

If the side A'B' is 8.2 units long, then the length of the side AB will be

AB = A'B' / 3

AB = 8.2 / 3

AB = 2.7 units

If the measure of the angles ∠A, ∠B, and ∠C are 77.5°, 54.2°, and 48.3°, respectively.

There is no effect of dilation on the angle. Then the angles will remain the same.

Answer:

x = 3 ± √23

Step-by-step explanation:

Simplify the quadratic equation.

[tex]3x^2-18x+5 = 473x^2-18x+5-47 = 0\\3x^2-18x-42 = 0\\\\a = 3\\b = -18\\c = -42\\\\x = (-(-18)\pm\sqrt{ (-18)^2-4(3)(-42) )} \div 2(3)\\x = (18\pm\sqrt{ 324+504)} \div 6\\x = (18\pm\sqrt{ 828}) \div 6[/tex]

Simplify further.

[tex]x = (18\pm\sqrt{ 23\times 36}) \div 6\\x = (18\pm6\sqrt{ 23}) \div 6\\x = 6(3\pm\sqrt{23}) \div 6[/tex]

Thus, the solution is

x = 3 ± √23

Hope this helps.

x = 3 + √23 and x = 3 - √23 are the two solutions of the given quadratic equation.

ax²+bx+c=0, with a not equals to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.

To solve for x in the equation 3x^2 - 18x + 5 = 47, we can begin by simplifying the equation:

[tex]3x^2 - 18x - 42 = 0[/tex]

Next, we can divide both sides of the equation by 3 to get:

[tex]x^2 - 6x - 14 = 0[/tex]

To solve for x, we can use the quadratic formula:

[tex]x =\frac{ (-b \pm \sqrt{(b^2 - 4ac))} }{ 2a}[/tex]

In this case, a = 1, b = -6, and c = -14, so we have:

[tex]x = \frac{(-(-6) \pm \sqrt{((-6)^2 - 4(1)(-14)))}}{2(1)} \\x = \frac{(6 \pm \sqrt{(36 + 56))}}{ 2} \\x = (6 \pm \sqrt{92}) / 2[/tex]

Simplifying the radical, we get:

x = (6 ± 2√23) / 2

Dividing both the numerator and denominator by 2, we get:

x = 3 ± √23

Therefore, the two solutions to the equation [tex]3x^2 - 18x + 5 = 47[/tex] are x = 3 + √23 and x = 3 - √23.

Applying the triangle sum theorem, the value of x is: 4.

When we add the three interior angles of a triangle together, the sum must be equal to 180 degrees according to the triangle sum theorem.

Given the triangle with the following interior angles, 35°, (22x - 3)°, and 60°. Therefore:

35 + (22x - 3) + 60 = 180 [triangle sum theorem]

Solve for x

35 + 22x - 3 + 60 = 180

Combine like terms

92 + 22x = 180

Subtract 92 from each side of the equation

92 + 22x - 92 = 180 - 92

22x = 88

Divide both sides by 22

22x/22 = 88/22

x = 4

Thus, applying the triangle sum theorem, the value of x is: 4.

The sequence is an arithmetic sequence due to the presence of a common difference.

An arithmetic sequence is a sequence that has a common difference while a geometric sequence is a sequence with a common ratio. For instance, given the sequence below:

a, b, c, d...

The sequence is an arithmetic sequence if;

common difference = b - a = c - b = d - c

The sequence is a geometric progression if;

common ratio = b/a = c/b = d/c

Given the sequence 17, 13, 9, ...

d = 13 - 17 = 9 - 13

d = -4

The number of 2 bedroom apartments that are there is 10.

Let the number of one bedroom = b

Since there are 5 more 2-bedroom apartments than 1- bedroom apartments. This will be b+5.

There are 15 apartments. Therefore, the expression will be:.

b + b + 5 = 15

2b + 5 = 15.

2b = 15 - 5.

2b = 10

b = 10 / 2

b = 5

The radiactive decay equation in terms of t that models the situation is 32 = 1024e^{(-0.0239/s)t}

Radioactive decay is the spontaneous disintegration of atoms with the emission of radiation.

The half life of a radioactive isotope is the time it takes for half the number of atoms in a given sample to disintegrate.

To model the situation, we use the equation for radioactive decay which is given below

[tex]N = N_{0}e^{-{\lambda}t}[/tex] where

Given that the half life of the isotope dubnium-263 is 29 seconds and  sample of dubnium-263 was first measured to have 1024 atoms. Then, after t seconds, there were only 32 atoms of the isotope remaining. we have that

So, λ = 0.693/29 s = 0.0239 /s

So, susbtituting the values of the variables into the equation, we have

The measure of the central angle m∠VWU is 69 degrees

Central angle is the angle formed by two arms and having the vertex at the centre of a circle.

The diameter of a circle runs from the centre of a circle.

The diameter SU and RT intersect each other at point Q.

Therefore,

m∠VWS = m∠TWU (Vertically opposite angles)

m∠VWU = m∠SWT (Vertically opposite angles)

Hence,

m∠TWU = 111 degrees.

Therefore,

m∠VWU = 360 - 111 - 111  /2

m∠VWU = 360 - 222 / 2

m∠VWU = 138 / 2

m∠VWU = 69 degrees

It is given that t = π/6 and we need to find the point (x y) on the unit circle that corresponds to the real number t.

Now,

Let us suppose that the real number 't' is to be of an arc length from the positive X-axis.

=> t = π/6

Further, if we look at the graph given below;

We observe that the reference angle π/6 is one of the standard angles with the ratio of opposite to adjacent sides as indicated above.
