The formula for finding any term of the given sequnce is [tex]a_{n}[/tex]  = n^3.

According to the given question.

We have a sequence

1, 8, 27, 64, 125

As we know that, a sequence or number pattern is an ordered set of numbers or diagrams that follow a rule.

The above of given sequence 1, 8, 27, 64, 125 is following a rule i.e each term is the cube of its number of term.

Here,

The first term is 1, so the cube of 1 is 1.

The second term is 8, so the cube of 2 is 8.

So, the nth term of the given sequnce is n^3.

Therefore, the formula for finding any term of the given sequnce is given by

[tex]a_{n}[/tex]  = n^3

Where, n = 1, 2, 3, 4...

So, for n = 1

The first term will be 1.

for n = 2

The second term will be 8

for n= 3

The fourth term will be 64.

Hence, the formula for finding any term of the given sequnce is [tex]a_{n}[/tex]  = n^3.

45 inch is shorter in length.

Feet is a unit of measuring length as per the US standard system of measurement and centimeters is the unit of length measurement as per the metric system. Feet is abbreviated as 'ft'.

Inches is another measurement of length . It is a unit used for measuring length, approximately equal to 2.54 centimetres, sometimes shown by the symbol ″

1 feet = 12 inches which means feet is a bigger unit than inch.

So 4 feet 1/2 inch = 54 inches

54 inches is greater than 45 inches,

45 inches is shorter.

Answer: SAS stands for side angle side and it means triangles are congruent by having the same side, angle, and side

Explanation: Let's say, two triangles both have the same angle, say 90 degrees. They also share two side lengths. Both triangles have a side length of 9 and another side length of 8.

The two triangles, sharing all these properties, must be congruent. This congruency is proven by SAS.

However, you must not get confused with other ways to prove congruency like ASA (Angle-Side-Angle)

The percent grade of the road will be 4.7692%.

It should be noted that the difference will be:

= 62/1300

= 31/650

= 0.047692

Answer: 3.162

Step-by-step explanation:

Answer:

√10 should be ~3.16

The solution of the equation 5x/4 - 3/x= 1/4 for x is (1+√241)/10 or (1 -√241)/10.

According to the given question.

We have an equation 5x/4 - 3/x= 1/4.

As we know that, an equation is a condition on a variable such that two expressions in the variable should have equal value.

Therefore, the solution of the equation 5x/4 - 3/x= 1/4 for x is given by

5x/4 - 3/x= 1/4

⇒ ( 5x^2 -12) /4x  = 1/4

⇒ 5x^2 - 12   = (1/4)4x                 (multiplying both the sides by 4x)

⇒ 5x^2 - 12 = x

⇒ 5x^2 - x -12 = 0

⇒ x = [tex]\frac{1\pm\sqrt{1+240} }{10}[/tex]

⇒ x = (1+√241)/10 or (1 -√241)/10

Hence, the solution of the equation 5x/4 - 3/x= 1/4 for x is (1+√241)/10 or (1 -√241)/10.

​According to the given data  4 a+6 b=6 and -2 a+b=-7 the value of a = 3.

The algebraic method for solving simultaneous linear equations is the substitution method. The value of one variable between one equation is exchanged in the second equation, as the name implies.

First, we will remove bb from the second equation and then substitute it in the first equation:

b= −7 + 2a

After replacing in the first equation:

(substitute)

4a+6(−7+2a) = 6

The equation of to represent the two unknowns y and x is undefined hence it can be said not to be existing.

Equation of a straight line is the equation of the form

y = mx + c

y and x are the unknown variables

m is the slope

c is the intercept in the y axis

The equation given in the problem is a special type which is a vertical line

A vertical line has no intercept on the y axis hence c =0/ This reduces the equation of a straight line to

y = mx + c

at c = 0 we have:

y = mx + 0

y = mx

The slope of the vertical line is undefined. From first principles we have that slope is

m = change in y / change in x

for a line to be vertical the change in x is at the lowest absolute value and the smallest absolute number is zero. note negative number is not inclusive.

Therefore the slope at change in x = 0 represents a vertical line which is

m = change in y / change in x

m = change in y / 0

m = undefined

so y = undefined

check using calculator any number divided by zero gives error which is defined mathematically to be undefined,

We can conclude that the relationship between y and x from the graph is undefined.

10th term of the geometric sequence = 2560

The explicit formula for the geometric sequence is

[tex]a_{n}[/tex] = a[tex]r^{n-1}[/tex]

Where  

r = common ratio

a = first number of the series

n = number of terms in the series

Common ratio (r) = 10/5 = 20/10 = 2

Here we have to find the 10th term of the series

[tex]a_{10}[/tex] = 5× [tex]2^{10-1}[/tex]

The probability of getting a number greater than 1 is 5/6

What is the formula of Probability?

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.

Probability of event happen P(E) = Number of favourable outcomes / Total number of outcomes.

The possible outcomes when a die thrown is {1, 2, 3, 4, 5, 6}. Therefore, the number of possible outcomes of a die is 6.

Now, the numbers greater than 1 between 1 to 6 are P{2, 3, 4, 5, 6} then the number of favourable outcome is 5.

Therefore, probability P of getting a number greater than 1 is:

P = 5/6

The final amount when $10,000 is invested for 3 years at 3% the interest is compounded continuously is  $10,942

What is compound interest ?

A compound interest rate is a rate of interest calculated on both the amount saved and the interest earned on it.

In the given question the expression to calculate amount is given as :

A = Pe^(rt)

where,

P = principle amount that is $10,000

r = rate of interest that is 3%

t = time period that is 3 years

Now, calculating Amount by substituting the above value in the formulae :

A = Pe^(rt)

A = 10000 e^(0.03 x 3)

A = 10000 e^(0.09)

A = 10000 x 1.0942

A = $10,942
