The values of a and b of the given sequence are; a = 6 and b = -15

We are given the formula for nth term of a sequence as;

an² + bn

We are given that;

Third term = 9

Sixth term = 126

Thus;

a₃ = 9 = a(3)² + b(3)

9a + 3b = 9    ------(1)

Similarly for the 6th term;

a(6)² + b(6) = 126

36a + 6b = 126    ------(2)

Multiply eq 1 by 2 to get;

18a + 6b = 18    ------(3)

Subtract eq 3 from eq 2 to get;

18a = 108

a = 6

18(6) + 6b = 18

6b = 18 - 108

6b = -90

b = -90/6

b = -15

The sesame street tube bought by the blue bird costs $177.92 which contained one gallon of toothpaste.

Given,

cost of regular toothpaste = $1.39 for 2.7 ounce tube

But the bird took a tube of toothpaste that contained one gallon of toothpaste.

One gallon = 128 ounces

∴the total price at which the toothpaste is brought = price of normal toothpaste × one gallon(128 ounces)

= 1.39 × 128

=$177.92

Here we can observe that a gallon contains 128 ounces. so we need to multiply to the initial cost of the toothpaste to get the final amount of the toothpaste bought by the bird.

Hence the price at which the bird bought the toothpaste is $177.92

$ (20b + 80) is the cost to buy a frame for the panting given that measures b meters by 4 meters and charges $10 per meter for a wooden frame. This can be obtained by finding the perimeter of the painting and multiplying with the cost of wood per meter.

Given that,

length of the painting (l) = b meters

width of the painting (b) = 4 meters

Perimeter of the painting = 2(l+b)

                                          = 2(b+4)

                                          = 2b + 8

Cost of the frame = (2b + 8)× $10 per meter

                             = $ (20b + 80)

Hence $ (20b + 80) is the cost to buy a frame for the panting given that measures b meters by 4 meters and charges $10 per meter for a wooden frame.

Answer:

1/40 or 0.025

Step-by-step explanation:

the weight of baby el is 200

the weight of mama el is 8000

take 200/8000 and simplify.

if you divide the top by 200 then divide the bottom by 200

200 divided by 200 is 1

8000 divided by 200 is 40

so the simplest fraction is 1/40

if you type this in to a calculator, you will find that it equals 0.025

Jose should charge $0.65 for each bag if he intends to sell the bag for $0.15 more than he paid.

Step-by-step explanation:

Let the consecutive positive integer be x , x+1

now, we know that there product is less then 10000

so, x(x+1) = 10000

x² + x - 10000 = 0

On solving the quadractic equation,

we get the roots = (-100.50124999219 ), (99.501249992188)

since we are asked for less then 10000 we can approximate the answer to x = 99.5

Answer:

99.5

Step-by-step explanation:

Let the consecutive positive integer be n , n+1

Answer:

14pi

Step-by-step explanation:

Answer:

Below in bold.

Step-by-step explanation:

The formula for the circumference

= 2πr   where r is the radius

= 2 * π * 7

= 14π

= 43.98 units to the nearest hundredth.

The area of the square LMNP is 50 square units

The circumference of the circle is given as:

C = 10π

Circumference is calculated as:

C = 2πr

So, we have:

2πr = 10π

Divide by 2π

r = 5

This represents the length OM

The length PM is calculated as:

PM = 2 * OM

This gives

PM = 2 * 5

PM = 10

The length (PN) of the square is then calculated as:

PM = PN√2

This gives

10 = PN√2

Square both sides

100 = PN^2 * 2

Divide by 2

50 = PN^2

Rewrite as:

PN^2 = 50

Hence, the area of the square LMNP is 50 square units

For the 0% acid, the initial and final mass are the same:

initial mass = final mass = 10.3g

Then the percent dissolved is:

[tex]percent\ disolved = \frac{10.3g - 10.3g}{10.3g}*100 \% = 0 \%[/tex]

For the 33% acid we have:

Then:

16 = 4 * 4

4x = 4 * x

( 4 * 7 ) / ( 5 * 7 ) = ( 4 * 4 ) / ( 4 * x )

Answer:

The runner in first place is 16 meters ahead of the runner in last place

Step-by-step explanation:

There are 4 boys racing - Pete, Nick, Manny, and Oliver.

Pete is 11 meters ahead of Nick, Oliver is 10 meters ahead of Manny, and Oliver is ahead of Pete by 5 meters.

This means Oliver is ahead of the other three racers, putting him in first place, and Manny is between Nick and Pete.

So in order to find out the distance between the racer in first place (Oliver) and the racer in last place (Nick), add the distance between Oliver and Pete and the distance between Pete and Nick.

Add the distances: 5 + 11

Therefore, the runner in first place (Oliver) is 16 meters ahead of the runner in last place (Nick).
