Answer 1

Answer:

a)  See below.

b)  Arithmetic sequence

[tex]\textsf{c)} \quad a_n=10n-7[/tex]

Step-by-step explanation:

Part (a)

From inspection of the given table, t(n) increases by 10 each time n increases by 1.

Therefore:

[tex]\implies a_7=53+10=63[/tex]

[tex]\implies a_8=63+10=73[/tex]

Completed table:

[tex]\begin{array}{|c|c|}\cline{1-2} \vphantom{\dfrac12} n&t(n) \\\cline{1-2} \vphantom{\dfrac12} 4& 33\\\cline{1-2} \vphantom{\dfrac12} 5& 43\\\cline{1-2} \vphantom{\dfrac12} 6&53 \\\cline{1-2} \vphantom{\dfrac12} 7&63\\\cline{1-2} \vphantom{\dfrac12} 8& 73\\\cline{1-2} \end{array}[/tex]

Part (b)

As the given sequence has a constant difference of 10, it is an arithmetic sequence.

Part (c)

[tex]\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]

The common difference is 10. Therefore:

d = 10

To find the first term, a, substitute the value of d and one of the terms into the formula:

[tex]\begin{aligned}\implies a_4=a+(4-1)(10)&=33\\a+3(10)&=33\\a+30&=33\\&a=3\end{aligned}[/tex]

Therefore, to write an equation for the given arithmetic sequence, substitute the found values of a and d into the formula:

[tex]\implies a_n=3+(n-1)(10)[/tex]

[tex]\implies a_n=3+10n-10[/tex]

[tex]\implies a_n=10n-7[/tex]

The given values are:

Height = 30cm

Large diameter = 16cm: Radius = 16/2 = 8cm

Small diameter = 4cm; Radius = 4/2 = 2cm

The volume will be:

= (3.14 × 8² × 30) - (3.14 × 2² × 30)

R = 4. 7 + 1 = 4. 7 kΩ = 4700Ω in series

[tex]I = \frac{12}{4700}[/tex]

[tex]I = 2. 6[/tex] × [tex]10^-3[/tex] A

Off the production line, there is a 2.2% chance that a candle is defective. If the company selected 40 candles off the line, what is the standard deviation of the number of defective candles in the group?

Answers

The standard deviation of the number of defective candles in the group is 0.9277.

When a random variable X follows a binomial distribution, with the sample size n, and the proportion of success is p, then the standard deviation is calculated as:

σ = √{np(1-p)}.

In the question, we are given that off the production line, there is a 2.2% chance that a candle is defective.

We are asked if the company selected 40 candles off the line, then what is the standard deviation of the number of defective candles in the group.

Assuming the occurrence of a defective bulb as success, we get the proportion of success, p = 2.2% or 0.022, and the sample size, n = 40.

Thus, we can calculate the standard deviation of the number of defective candles in the group as:

σ = √{np(1-p),

or, σ = √{40*0.022*(1 - 0.022)} = √0.86064 = 0.9277.

Thus, the standard deviation of the number of defective candles in the group is 0.9277.

write the expression 5x(x+9) -7(x+9) in complete factored form.

Answers

5x^2 + 45 - 7x - 63 which simplifies to 5x^2 -7x -18?
Answer:

(5x-7)(x-9)

Step-by-step explanation:

Factoring is the inverse of the distributive property. This means that we want to find the factors, not the product.

Partial Factoring

The expression we are given has already been factored to an extent. Both terms are split into 2 different factors. This was done by factoring out the greatest common factor (GCF) from both terms. In the first term, the GCF was 5x, and in the second, the GCF was -7.

Complete Factoring

Even though it was partially factored, we can factor it more. When given the situation:

a(x + y) - b(x + y)

The expression can be factored into:

(a - b)(x + y)

You can add (subtract in this case because 7 is negative) the values from outside the parentheses together. This term can then be multiplied by the value within the parentheses.

Thus, 5x(x+9) -7(x+9) can be factored into:

(5x-7)(x-9)

Remember this trick only works when both terms share a factor like (x-9).

Answers

The expression of the given logarithmic function 2log(2/√5) is; D: -0.097

How to solve Logarithmic Functions?

From logarithmic Identities, we know that;

log (x/y) = log x - log y

log (x * y) = log x + log y

Thus;

2log(2/√5) = 2[log 2 - log √5)

Now, log √5 can also be expressed as;

log √5 = ¹/₂log 5

Thus;

2log(2/√5) = 2[log 2 - ¹/₂log 5]

⇒ 2 log 2 - log 5

We are given the values;

log2≈0.301, log3≈0.447, log4≈0.602, log5≈0.699

If (one month) I make a total of 10 hours of calls at Standard hours , how much more or less will I pay for basic contact than for premium

Answers

The amount of money that you would pay less for basic contact is $15 while the amount you will pay more for premium =$465.

Calculation of the call rate per hour

From the given table in the diagram, the cost of calls made for 10 hours at Standard time=

$6 × 10 = $60

The amount of calls done for basic contact is 3 hours per month for $15 . Total cost per month = 3×15= $45

The amount of calls done for premium contact is 15 hours per month for $35 . Total cost per month = 15× 35=$525

Ordinarily, you per $60 for standard call hours. This means that,

$60 - 45 = $15 less for basic contact and

$525 - $60 = $465 more for premium.

Answers

Based on the given horizontal and vertical sides of a rectangle and its perimeter, the value of x in the expression is 6

Perimeter of rectangle

Perimeter of rectangle = 2(length + width)

Perimeter of the rectangle = 34 ft

Length of the rectangle = 3(x - 2) ft

= 3x - 6

Width of the rectangle = 4x - 7 + (-2x)

= 4x - 7 - 2x

= 2x - 7

Perimeter of rectangle = 2(length + width)

34 = 2{(3x - 6) + (2x - 7)}

34 = 2(3x - 6 + 2x - 7)

34 = 2(5x - 13)

How to determine the number of unique passwords?

The characteristics of the password are given as:

Number of characters = 5First, third, and fifth characters in the password = One of the letters A to ESecond and fourth characters = one of the numerals 0 through 9

Since the characters in the password must unique, we have the following possibilities

First character = Any of 5 charactersSecond characters = Any of 10 digitsThird character = Any of remaining 4 charactersFourth characters = Any of remaining 9 digitsFifth character = Any of remaining 3 characters

So, the number of unique passwords is

Condition 1: Both lines must have the same slope (i.e the same x in the form y = mx + b)

Condition 2: Both lines must have different y-intercepts (i.e different b in the form y = mx + b)

Thus, if you are looking for the slope of the line parallel to y = 4/5x - 3, we can look at condition 1, and see that the slope should also be 4/5 for the other line.
