Describe the pattern 0.13, 0.65, 3.25, 16.25
Oksi-84 [34.3K]

Let n be the current term and n+1 be the next term

Then the pattern is: n+1 = n * 5

Step-by-step explanation:

Given series is:

0.13, 0.65, 3.25, 16.25

We can find the ratio between consecutive numbers to find the pattern

So,

Ratio = \frac{0.65}{0.13}\\=5

We can see that multiplying the previous term with 5 gives us the next term

0.13 * 5 = 0.65

0.65 * 5 = 3.25

3.25 * 5 = 16.25

Let n be the current term and n+1 be the next term

Then the pattern is: n+1 = n * 5

Please help me so confused Solve. x^2 + 3x − 7 = 0 Enter your answers, as exact values, in the boxes. x = or x =
Rzqust [24]

Answer:

x = -1/2 ( 3±sqrt(37))

Step-by-step explanation:

x^2 + 3x − 7 = 0

Add 7 to each side

x^2 + 3x =7

Using complete the square

Taking the coefficient of x

3

Divide by 2

3/2

Square it

(3/2)^2 = 9/4

Add this to each side

x^2 + 3x+ 9/4 = 7+9/4

( x+ 3/2) ^2 = 28/4 + 9/4

( x+ 3/2) ^2 = 37/4

Take the square root of each side

x+3/2 = ±sqrt(37/4)

x+3/2 = ±sqrt(37) / sqrt(4)

x+ 3/2 = ±sqrt(37) / 2

Subtract 3/2 from each side

x = -3/2 ±sqrt(37) / 2

x = -1/2 ( 3±sqrt(37))

Find the midpoint of the line segment joining points A and B A(2,-5); B(6,1)
Rzqust [24]

Answer:

<h3>The answer is ( 4 , - 2)</h3>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} ) \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(2,-5); B(6,1)

So we have

M = ( \frac{2 + 6}{2}   \: , \:  \frac{ - 5 + 1}{2} ) \\  = ( \frac{8}{2}  \: , \:  -  \frac{4}{2} )

We have the final answer as

<h3>( 4 , - 2)</h3>

Hope this helps you
