The top number is 4 and t =1, so you need to replace t with 1, find the answer, then replace t with 2 through 4, then find the sum of all of them:


6^1-1 = 6^0  = 1

6^2-1 = 6^1 = 6

6^3-1 - 6^2 = 36

6^4-1 = 6^3 = 216


Sum = 1 + 6 + 36 + 216 = 259


The answer is B.

Answer:

B 259

Step-by-step explanation:

The sum is 4 terms, so we need to add the 4 terms

Term 1: 6 ^ (1-1) = 6^0 = 1

Term 2: 6^ (2-1) = 6^1 = 6

Term 3: 6^ (3-1) = 6^2 = 36

Term 4: 6^ (4-1) = 6^3 =216

The sum is  1+6+36+216 = 259

You bought an investment for $1000 and 5 years later sold that investment for $1700. Taking into account compounding, what was y
igor_vitrenko [27]

Answer:

11.196%

Step-by-step explanation:

Given:

Buying cost of the investment or the principle amount = $1000

Time, n = 5 years

Selling cost of investment or amount received = $1700

Now,

the formula for compound interest is given as:

\textup{Amount}=\textup{Principle}(1+r)^n

here, r is the rate of interest

on substituting the respective values, we get

\textup{1700}=\textup{1000}(1+r)^5

or

(1 + r)⁵ = 1.7

or

1 + r = 1.11196

or

r = 0.11196

or

r = 0.11196 × 100% = 11.196%

Which of the following statements regarding Pascal's triangle are correct?
tia_tia [17]

Answer:

Option A, C and D are correct.

Step-by-step explanation:

Option A is correct because if we take example of (x+y)^3 we get:

     1,2,1

   1,3,3,1

  1,4,6,4,1

So we can see that either we read left to right or right to left we are getting same row

Option B is not correct because When we take power zero it will occupy first row hence, (x+y)^n  is not given by nth row.

Option C is correct because adding adjacent terms on a will give us the term directly below look at the example in option A.

Option D is correct because nth row will give coefficients in the expansion of (x + y) n-1 since, zero will occupy first row hence, nth row will be n-1.

HELP!!BRAINLIEST!!<br> 9. Identify the congruent triangles in the figure.
LenKa [72]
<h3>Answer: Choice A) triangle FDE = triangle IGH</h3>

There are 3 ways to label any triangle. We simply list 3 points in any order. Once we pick an order, the other triangle must follow that same pattern for the sides and angles to match up.

With choice A, we start at the bottom for both triangles (points F and I). For the triangle on the right, we go in counterclockwise direction to get F, D, then E. So we have FDE. The triangle on the left will go opposite this and we go clockwise: I to G to H. So we have IGH.

angle F = angle I

angle D = angle G

angle E = angle H

segment FD = segment IG

segment DE = segment GH

segment EF = segment GI

Solve the simultaneous equation: x-y=2
kakasveta [241]

Answer:

Y= –7.08, 5.08

Step-by-step explanation:

hope ya ready bro.

X=36/Y

replace 36/y instead of X

36/Y–Y=2===> 36–Y²=2Y===> Y²+2Y–36=0

Y1= –1+√37≈ –7.08

Y2= –1–√37≈ 5.08
