Graph the six terms of a finite series where a1 = −3 and r = 1.5.
s344n2d4d5 [400]
We are given the first term and the common ratio, this means they belong to a geometric series.

For the given series:

a_{1}=-3 \\ 
r=1.5

Each term of the geometric series is obtained by multiplying the previous term by common ratio.

So the next terms will be:

-4.5, -6.75, -10.125, -15.1875, -22.78125

The general formula for the G.P would be:

a_{n}=-3(1.5)^{n-1}

On plotting the series, the result will be like this:

Fill in the blank with a number to make the expression a perfect square.<br><br> U^2 + 2u + ?
babymother [125]

Answer:

u² + 2u + <u>1</u>

Step-by-step explanation:

In the question it's asking to find the the number in the blank to make the expression a perfect square.

Let the number in the blank be 'x'.

To guess 'x' , use the algebraic identity :- (a + b)^2 = a^2 + (2 \times a \times b) + b^2

While matching the expression with identity , the expression will look like this :- <em>u² + 2ux + </em><u><em>x²</em></u>

In the expression given in the question , it's "2u" but after matching the expression with identity , it is found to be "2ux".

⇒ x = 1 (∵ If x will be 1 , then 2ux = 2×u×1 = 2u)

⇒ <u>x²</u> = <u>1</u>

∴ The number in the blank is 1.
