The geometric series given as 1000, 500, 250, 125,... is seen to be; Convergent.

A series is said to be divergent if it doesn't converge at any finite point. However, a series is said to be convergent if it converges at a finite point.

In this question, we see the series progressively reducing by one quarter of the previous number. Thus, it means that the sequence will converge close to zero and as such we can say taht the sequence is convergent.

Formula for sum of geometric series is;

Sₙ = a(1 - rⁿ)/(1 - r)

Thus;

S₁₀ = 1000(1 - 0.5¹⁰)/(1 - 0.5)

S₁₀ = 1998.05

Sum of first 30 terms is;

S₃₀ = 1000(1 - 0.5³⁰)/(1 - 0.5)

S₃₀ = 2000

Step-by-step explanation:

First divide S by 4pi. Then take the square root to solve for r.

The measurement unit used for the water in the swimming pool is 2.3×10⁴ gallons.

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimeter is equal to 10 mm,

Though the real measurement is still the same the units and numerical values have been changed.

As it is given, the pool's volume or the amount of water in the pool is equal to 2.3×10⁴ units.

We know that an average swimming pool has a volume of water that is in gallons, therefore, the unit of water that will be filled in the swimming pool will be equal to 2.3×10⁴ gallons.

Hence, the measurement unit used for the water in the swimming pool is 2.3×10⁴ gallons.

The solution of the given quadratic equation are,

[tex]x=\frac{-5-\sqrt{57} }{2}[/tex],[tex]x=\frac{-5+\sqrt{57} }{2}[/tex]

The equation to solve is given as

[tex]x^2=-5x+8[/tex]

Rearrange the given equation in standard form, [tex]ax^2+bx+c=0[/tex]

where,  a,b and c are constants.

Therefore, we add 5x-8 on both sides to get,

[tex]x^2+5x-8=0[/tex]

Here, a=1,b=5 and c=-8

The solution to the above equation is

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

Use the value of a,b,c in the quadratic formula and solve for x

[tex]x=\frac{-5\±\sqrt{5^2-4(1)(-5)} }{2(1)}[/tex]

[tex]x=\frac{-5\±\sqrt{25+35} }{2(1)}[/tex]

[tex]x=\frac{-5\±\sqrt{57} }{2(1)}[/tex]

Therefore, the solutions are

[tex]x=\frac{-5-\sqrt{57} }{2},x=\frac{-5+\sqrt{57} }{2}[/tex]

Answer:

21 and 32 are the numbers

Step-by-step explanation:

Let assume that the the two numbers are X and Y and that X is the large number.

According to the question,

X + Y = 53 .................. Equation 1

then,  X = 11 + Y........... Equation 2

Substitute equation 2 into equation 1.

[11 + Y] + Y = 53

11 + 2Y = 53

2Y = 53 - 11 = 42

2Y = 42

Y = 42 / 2 = 21,

Therefore, Y = 21 [Small number].

According to equation 1,

X +Y = 53

X + 21 = 53

X = 53 - 21 = 32.

Therefore, X = 32 [Big number]

If we take value of x as 6 in the given function, then we will get the value of y as 4, as shown in the graph.

The volume of a cuboid is the product of its length, width, and height. The total volume with Selina is 360 in³.

The volume of a cuboid is the product of its length, width, and height. It is represented as,

[tex]\rm \text{Volume of Cuboid} = (Length \times Width \times Height)\ unit^3[/tex]

The volume of each of the boxes with a width of 6 in, a height of 3 in, and a length of 4 in, can be written as,

[tex]\rm \text{Volume of a single Box} = 6\ in \times 3\ in \times 4\ in = 72\ in^3[/tex]

Now, the total number of boxes Selina has is 5, therefore, the total volume with Selina can be written as,

[tex]\rm \text{Total\ Volume} = \text{Volume of a single box} \times 5 = 72\ in^3 \times 5 = 360\ in^3[/tex]

Hence, the total volume with Selina is 360 in³.
