Answer:

(a)

[tex]T_n = 3(-4)^{n-1}[/tex]

(b)

[tex]\sum\limits^n_1 { 3(-4)^{n-1}[/tex]

Step-by-step explanation:

Given

The above sequence

Solving (a): The explicit formula

The given sequence is a geometric sequence because the common ratio (r) is:

[tex]r = \frac{-12}{3} = \frac{48}{-12} = \frac{-192}{48} = \frac{768}{-192}[/tex]

[tex]r = -4[/tex]

The explicit formula is calculated using the n term of an GP.

[tex]T_n = ar^{n-1}[/tex]

[tex]T_n = 3 * (-4)^{n-1}[/tex]

[tex]T_n = 3(-4)^{n-1}[/tex]

Solving (b): Summation notation.

This implies that the sum of the sequence.

To do this, we write Tn inside the summation sign

i.e.

[tex]\sum\limits^n_1 {T_n}[/tex]

Substitute values for Tn

[tex]\sum\limits^n_1 { 3(-4)^{n-1}[/tex]

Answer:

136

Step-by-step explanation:

12x + 4 = 11x + 15 {Subtract 11x from both sides.}

(12x - 11x) + 4 = 15

x + 4 = 15 {Subtract 4 from both sides.}

x = 15 - 4

x = 11

Now, SUBSTITUTE 11 for x in 11x + 15.

11(11) + 15

121 + 15

Answer: The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Answer:

The answer is "no".

Step-by-step explanation:

No, because the probability besides simultaneous flights to arrive on time are not self-sufficient for every flight (when the first flight was late, therefore the probabilities during the next flight were significantly greater), because then the standard multiplication principle would be used for explanatory variables.

Yes, we can multiply (0.85)(0.85)(0.85)(0.85)

Let the four flight be represented by A, B, C, and D respectively

Probability that each of the flights arrive on time is 0.85

That is:

Probability that flight A arrives on time, P(A) = 0.85

Probability that flight B arrives on time, P(B) = 0.85

Probability that flight C arrives on time, P(C) = 0.85

Probability that flight D arrives on time, P(D) = 0.85

Probability that the next four flights arrive on time will be:

P(A) x P(B) x P(C) x P(D) = 0.85 x 0.85 x 0.85 x 0.85

Yes, we can multiply (0.85)(0.85)(0.85)(0.85)

First we can write the equation to find the surface area of a rectangular prism[tex]A = 2(w*l+h*l+h*w)[/tex]

Now rewrite filling in variables

[tex]A = 2(3*5+8*5+8*3)[/tex]

Solve. Keep in mind the order of operations

After solving, you should get 158.

Since these measurements were done in inches, we need to add inches/in to the end.

Also, since it is area, we need to add ²

Amount paid by Joanne before promotion = 74 + 59 + 69 = $ 202

a) Amount saved if she switches to "3 for 129 plan" = 202 - 129 = $ 73

Percentage of saving = [tex]\frac{73}{202}*100[/tex] = 36.13 = 36%

Answer:

answer is 90 hr for question 1

Step-by-step explanation

48 hr     8 liter

 ?           15 liter

so what ur going to do is u criss-cross when u do u multipy 48 with 15 and 8 with "?" when u multiply 48 with 15 u get 720 and when you multiply 8 with "?" u get 8?

so it will look like this

720= 8?

let make "?" an "x" for a better understanding. so the reason we are making it an "x" is because we dont know the amount of hr it takes for 15 liters of water to leak.

let go back to the calculation.

so it will look something like this

720 = 8x

exactly the same thing but we made "?" an"x"

so now we divide both sides with 8. why? because we need "x" alone and want 8 to disappear

so when u divide both sides with 8 it will look something like this

780/8 =x

so when u divide 780 with 8 u get 90. so what does that mean? it means it takes 90 hr for 15 liters of water to leak.

do you understand?
