Provide the first six terms of the following sequence: t1=81 tn=13tn-1n ≥ 2

Answer:

a

Step-by-step explanation:

the mean = [tex]\frac{total score}{count}[/tex]

let the fifth score be x and count = 5, hence

[tex]\frac{86+82+72+69+x}{5}[/tex] = 79 ( multiply both sides by 5 )

309 + x = 395 ( subtract 309 from both sides )

x = 86

the student requires a score of 86% → a

Answer:

a1 = 8

a2 =10

a3 = 13

a4 = 17

Step-by-step explanation:

The first term is a1 = 8

The second term is a2 = a1 + n

                                       = 8+2

                                       = 10

The third term is a3 = a2 + n

                                       = 10+3

                                       = 13

The fourth term is a4 = a3 + n

                                       = 13+4

                                       = 17

Answer:

I believe it is 2 / h = the amount she blew in 1 minute. Hope this helps

Answer:

h / 120

Step-by-step explanation:

2 hours equals 120 minutes.

So h bubbles in 120 minutes is h/120 per minute.

Verification: suppose she blew 240 bubbles in two hours; this would be 240/120 = 2 per minute. That makes 120 per hour and, as expected, 240 in two hours.

Answer:

You should recruit a total of 525 subjects for the whole study.

Step-by-step explanation:

The question states that you want 175 subjects per group for 3 groups.  This indicates that we need to either multiply 175 times 3, or we can add 175 three times to get the total number of subjects we would need to recruit.  Group 1 should have 175, Group 2 should have 175 and Group 3 should have 175.  Whether we multiply 175 x 3 or add 175+175+175, we get a final anser of 525.

Answer:

y = 33/5 or 6.6

Step-by-step explanation:

7y + 44 = 12y + 11

      -11              -11

7y + 33 = 12y

-7y           -7y

33 = 5y

Divide both sides by 5

= 33/5 or 6.6

Answer:

[tex]y=6\frac{3}{5}[/tex]

Step-by-step explanation:

We are given the following equation for which we have to solve for y:

[tex]7y+44=12y+11[/tex]

So first of all, we will rearrange the terms by putting the like terms together (variables on one side of the equation and constants on the other side) to get:

[tex]12y-7y=44-11[/tex]

Then solving for y:

[tex]5y=33\\\\y=\frac{33}{5}[/tex]

Therefore, the value of y is equal to [tex]y=6\frac{3}{5}[/tex] (rewriting y in a mixed fraction form).

Answer:

[tex]a=1,\ 2,\ 3,\ 6.[/tex]

Step-by-step explanation:

A whole number is any number of a set [tex]\{0,\ 1,\ 2,\ 3,...\}[/tex]

The equation [tex]ax=6[/tex] has a solution [tex]x=\dfrac{6}{a},\ a\neq 0.[/tex]

If [tex]a=1,[/tex] then [tex]x=\dfrac{6}{1}=6[/tex] is a whole number.

If [tex]a=2,[/tex] then [tex]x=\dfrac{6}{2}=3[/tex] is a whole number.

If [tex]a=3,[/tex] then [tex]x=\dfrac{6}{3}=2[/tex] is a whole number.

If [tex]a=6,[/tex] then [tex]x=\dfrac{6}{6}=1[/tex] is a whole number.

For all other values of [tex]a[/tex] equation  [tex]ax=6[/tex]  will have solution that is not a whole number.

Answer:

The answer is ASA.

Step-by-step explanation:

There is one other angle in the middle which is congruent to its self.

ASA (Angle-Side- Angle) method can we use to prove that the triangles are congruent

Two triangles are called to be congruent if their sides have the equal length and angles have equal measure.

Thus, two triangles can be superimposed side to side and angle to angle.

If any two angles and the side of the angles of triangle are equivalent to the corresponding, then the two triangles are said to be congruent by ASA rule.

Final answer:

The total interest cost of the loan is $28,999.

Explanation:

To find the total interest cost of the loan, we need to calculate the amount of interest paid over the 25-year period. First, we need to find the amount of the mortgage by subtracting the down payment from the purchase price. 20% of $230,000 is $46,000, so the mortgage is $230,000 - $46,000 = $184,000.

To calculate the interest cost, we can use the formula: Interest Cost = Total Repayment - Principal Amount.

Principal Amount = Mortgage Amount = $184,000.
Number of Payments = Number of years x Number of payments per year = 25 x 12 = 300.
Monthly Interest Rate = Annual Interest Rate / Number of payments per year = 8% / 12 = 0.00667.
Total Repayment = Monthly Payment x Number of Payments = [(Monthly Interest Rate x Principal Amount) / (1 - (1 + Monthly Interest Rate)^(-Number of Payments)) ] x Number of Payments = [(0.00667 x $184,000) / (1 - (1 + 0.00667)^(-300))] x 300 = $526.67 x 300 = $157,001.
Interest Cost = Total Repayment - Principal Amount = $157,001 - $184,000 = $28,999.

Put the value of slope to the equation of the function:

[tex]y=-\dfrac{1}{6}x+b[/tex]

Put the coordinates of the point B(12, 3) to the equation:

[tex]3=-\dfrac{1}{6}(12)+b[/tex]

[tex]3=-2+b[/tex]            add 2 to both sides

[tex]5=b[/tex]

Answer:

The value of b is 5.

Step-by-step explanation:

Consider the provided information.

It is given that the slope intercept form is, y = mx + b

Where m is the slope and b is the y intercept.

Also, it is given that the slope of the line is -1/6.

Line AB passes through points A(–6, 6) and B(12, 3).

That means Point A and B must satisfy the equation of line.

Substitute [tex]m=\frac{-1}{6}, x=-6\ \text{and}\ y = 6[/tex] in slope intercept form:

[tex]6=\frac{-1}{6}\times(-6)+b[/tex]

[tex]6=1+b[/tex]

[tex]5=b[/tex]

Thus, the value of b is 5.

t...time

if he was 15 min late he arrived at 12:15

v=s/t => t=s/v

t = 60/40 = 1.5 h = 1h and 30 min

if he arrived at 12:15 and he was driving for an hour and a half just substract

12:15 - 1:30 = 11:15 - 0:30 = 10:45

Answer: 164.4 or 165

Step-by-step explanation: So, you do 226 x 3 and you get $678. So now that you know that you have $678 worth of student tickets, you want to find how much more you need for the adult tickets, so you do $1500-$678, and you get $822. Divide it by 5 and you get 164.4, so you wanna sell about 165 tickets. Check your work by multiplying 5 by 165 and you get $825, which meets your $1500 minimum

After calculating the revenue already obtained from the student tickets sold, the remaining revenue needed to reach $1500 is found. This amount is divided by $5 (the cost of an adult ticket) to find the minimum number of adult tickets needed. Since you can't sell fractions of tickets, we round up to the next whole number, which is 165 adult tickets.

The first step to solve this problem is to calculate how much revenue has already been raised from the student tickets sold, which is $3 x 226 = $678. Then subtract this amount from the total revenue target of $1500, which gives $1500 - $678 = $822.

The choir director now needs to raise $822 from selling adult tickets. As each adult ticket costs $5, we can calculate the minimum number of adult tickets that need to be sold by dividing the amount of revenue needed by the price of an adult ticket. This is $822 / $5 = 164.4.

Since you can't sell .4 of a ticket, we'll need to round up to the next whole number, giving a minimum of 165 adult tickets that need to sell in order to reach the revenue target.

Answer:

Area of the figure is 304 sq. units

Step-by-step explanation:

The area is divided into two identical trapezoids of height 8 units and bases 14 and 24 units.

Area of a trapezoid = (1/2) * (Sum of base lengths) * height

So, area of 1 one trapezoid = (1/2)*(14+24)*8=152

The area of the figure is twice the area of the trapezoid.

So, area of figure = 2 * 152 = 304 sq. units

∴ Area of the figure is 304 sq. units

Answer:

5.91%

Step-by-step explanation:

We are given an investment deposited fro 1 year compounded daily at an annual interest rate of 5.75%.

Compounding period per year, n: 365

The effective annual yield can be calculated by the following formula:

Effective Annual Yield = [tex] (1+\frac{r}{n})^{n}-1[/tex]

where n = 365

Interest rate, r= 5.75% = 0.0575

[tex]=(1+\frac{0.0575 }{365})^{365}-1[/tex]

= 0.059

The annual effective yield is 5.91%
