Answer:

∴ ∑₁⁸i = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8

Step-by-step explanation:

Given:

To Find:

∑₁⁸i =?

Solution:

Σ This symbol called Sigma means "summation up"

∴ ∑ n mean sum for all n

But if ∑₁³n means Sum for n=1 , 2 ,and 3 ADD

∴ ∑₁³n = 1 + 2 + 3

∴ ∑₁⁸i = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8

I belive it would be B. because of the fact that they are parallel which means their slope should stay the same...but their y-intersept would change

Find the sumofthe geometrical progression of five terms, of which the first term is 7 and the multiplier is 7.Verify that the su

Answer:

The sum of first five term of GP is 19607.

Step-by-step explanation:

We are given the following in the question:

A geometric progression with 7 as the first term and 7 as the common ration.

$a, ar, ar^2,...\\a = 7\\r = 7$

$7, 7^2, 7^3, 7^4...$

Sum of n terms in a geometric progression:

$S_n = \displaystyle\frac{a(r^n - 1)}{(r-1)}$

For sum of five terms, we put n= 5, a = 7, r = 7

$S_5 = \displaystyle\frac{7(7^5 - 1)}{(7-1)}\\\\S_5 = 19607$

The sum of first five term of GP is 19607.

Verification:

$2801\times 7 = 19607$

Thus, the sum is equal to product of 2801 and 7.

Convert to factored form y = x² + 6x

steposvetlana [31]

Convert to factored form is:

$y = x(x + 6)$

Solution:

Given that,

$y = x^2 + 6x$

We have to convert to factored form

Factored form means writing terms in multiplication. i.e as a product

From given,

$y = x^2 + 6x$

Factor out x from above given expression

$y = x(x + 6)$

Here, the given equation is written as product of "x" and (x + 6)

Thus the factored form is found
