There is a Constant Ratio between consecutive terms in a geometric sequence.

The consecutive terms in a Geometric Progression or Sequence are separated by a Constant Ratio which remains constant for the whole sequence and all of the terms in that sequence are separated by that Ratio. Generally, the Constant Ratio is denoted by 'r'. The next term of the sequence can be determined by using this Ratio.

To determine the next term or [tex]n^{th}[/tex] term, we need to multiply the previous term with the Ratio. There is a specific formula to determine the [tex]n^{th}[/tex] term in a geometric sequence.

Answer: 3 3/4

Step-by-step explanation:

The plant is 4 3/4 below ground, but then it grows 8 1/2.

Use subtraction to find the difference.

8 1/2 - 4 3/4 = 3 3/4

Answer:the answer would be 3 3/4

Step-by-step explanation:

After determining whether y is a function of x we have come to conclusion that y is not a function of x.

x² = 3y + y

x² = 4y

y = x²/ 4

Here x has two values of -x and x as -x² = x². Therefore, y is not a function of x.

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

The fluid is redirected by the rudders, which then produce an opposing force that helps the boat move in the desired direction.

According to Isaac Newton's law, whenever an object X applies a force on another object Y, object Y must respond by applying a force that is equal in magnitude but directed in the opposite direction.

In the case of the rudder, it causes the fluid to flow in a different direction while still exerting an equivalent force of the same size. Consequently, this causes the boat to move, making it the best option.

Answer:

  D. The theory is based on the idea that an explosion did not occur; therefore, evidence of radiation would not be predicted in the theory.

Step-by-step explanation:

You want to identify the statement that best describes why the steady state theory cannot explain the radiation detected in space.

The Big Bang theory explains the cosmic background radiation as remanent thermal energy from the explosion creating the known universe. The Steady State theory presumes there was no explosion. It offers no alternative explanation for the observed cosmic background radiation.

The cosmic background radiation was first observed in 1965 by two radio astronomers who set out to map radio signals from the Milky Way. They found microwave signals that could not be attributed to a specific source, and were of the same intensity in every direction at every time of day or season of the year. The spectrum of this radiation is consistent with a source temperature of about 2.725 K, explained as the cooled remains of the hot plasma that once filled the universe.

Using proportions, it is found that she would save $900 in a year.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

She spends $150 a month on clothing and accessories, hence, if she saves half of that, the amount saved in a month is:

0.5 x 150 = $75.

According to the given statement;

The probability of student Who scored less than 350 is 0.0643.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. The concept of probability was developed to forecast the likelihood of certain events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a certain event will occur.

According to the given value;

Population Mean,μ = 528

Population Standard Deviation,σ = 117

X follows normal distribution

I.e X ~ N ( μ = 528 ,σ = 117 )

Answer: 4 10/11

Step-by-step explanation:

The length of BC is B. 2.20 cm

As per the known fact, the linear angle is 180°. As per this writing the equation -

∠ BC + 168 = 180

∠ BC = 180 - 168

∠ BC = 12°

Now, using formula  for calculation of length of arc -

Length = angle/360×2πr, where r refers to radius

Calculating radius as -

Radius = diameter ÷ 2

Radius = 21 ÷ 2

Radius = 10.5 centimeters

Now keep the values in formula to find the length of arc, which is the value of BC

Length = 12/360×2×3.14×10.5

Length = 252×3.14/360

Length = 2.2 centimeters

In topology, the Pointcare conjecture is the one that states a 3-dimensional mainfold is the same as the 3-dimensional sphere.

Topology is a branch derived from geometry, this branch focuses on studying and analyzing geometrical properties and spatial relationships. One of the focuses of this area is the equivalences of some shapes or spaces.

This conjecture created by Pointcare in the 19th century proposes a three dimensional mainfold is the same or it is equivalent to a three dimensional sphere.

This conjecture was first proven as valid by Pointcare and other mathematicians/experts in the topic. However, some years later the same Pointcare and other experts showes this conjuction is not always true and therefore it is not valid.

Despide this, to this day this conjecture remains very popular and people around the world are still trying to prove it or dispprove it.

Answer:  Choice C

(2, 4) and (0, -4)

========================================================

Explanation:

Let's solve the first equation for y

4x - y = 4

-y = -4x+4

y = 4x-4

Now plug this into the other equation and solve for x.

2x^2 - y = 4

2x^2 - ( y ) = 4

2x^2 - ( 4x-4 ) = 4

2x^2 - 4x+4  = 4

2x^2 - 4x+4-4 = 0

2x^2 - 4x = 0

2x(x - 2) = 0

2x = 0 or x-2 = 0

x = 0 or x = 2

-----------------

If x = 0, then,

y = 4x-4

y = 4(0)-4

y = -4

This gives one solution as (0, -4)

-----------------

If x = 2, then,

y = 4x-4

y = 4(2)-4

y = 4

The other solution is (2, 4)

-----------------

To check the answers, plug the x and y coordinates into each equation. You should get the same thing on both sides.

The total surface area of the box is 138in².

What is surface area of cuboid?

Formula for calculating the surface area of the box S = 2(LW+LH+WH) where

L is the length of the box

W is the width of the box

H is the height of the box

If the box is square based with dimension 4 * 4in, then L = W = 4in. substituting this values given into the formula we will have;

S = 2(4(4)+4H + 4H)

S = 2(16+8H)

S = 32+16H

Hence, The function that represents the surface area of this box as a

function of its height is S = 32+16H where H is the height of the box

Given H = 6.5in, to evaluate the function, we will substitute h = 6.5in into the modeled equation;

S = 32+16H

S = 32+16(6.5)

S = 32+106

S = 138in²

Hence the total surface area of the box is 138in².

The given arithmetic series can be expressed in summation notation as [tex]\sum\limits^8_{n=1} {(2n+5)}[/tex] or in simplified notation [tex]40+2 \sum\limits^8_{n=1} {n}[/tex]

The summation notation is used to express long summation in one expression.

The given arithmetic series is:

       7+9+11+ . . . . . . +21

Find the explicit formula for the nth term in the given series.

Recall:

a(n) = a(1) + (n-1) . d

where:

a(1) = the first term

d = common difference = a(2) - a(1) = a(n) - a(n-1)

From the series, we get:

a(1) = 7

d = 9 - 7 = 2

Hence,

a(n) =  a(1) + (n-1) . d

a(n) = 7 + (n-1) . 2

a(n) = 2n + 5

Find number of terms in the given series.

From the given series, we know that the last term is 21.

Let the last term be a(n), then,

a(n) = 2n + 5

21 = 2n + 5

2n = 16

n = 8

Write the summation notation with lower limit n = 1 and upper limit n = 8.

[tex]\sum\limits^8_{n=1} {a(n)}= \sum\limits^8_{n=1} {(2n+5)}[/tex]

If necessary, simplify the summation.

[tex]\sum\limits^8_{n=1} {(2n+5)}= \sum\limits^8_{n=1} {2n}+ \sum\limits^8_{n=1} {5}[/tex]

[tex]= \sum\limits^8_{n=1} {2n}+ 8\times5[/tex]
