Determine whether the given sequence could be geometric, arithmetic, or neither. if possible, identify either the common ratio o

REY [17]

ARITHMETIC CHECK: A sequence is said to be arithmetic if any two consecutive terms differ by the same constant.

So, the test to check if a series is arithmetic is to compute consecutive differences, and see if they all return the same number.

If we subtract the first two terms, we have $2-4 = -2$ . If we subtract the third and second terms, we have $1-2 = -1$ .

These two differences returned two different values, so the series is not arithmetic.

GEOMETRIC CHECK: A sequence is said to be geometric if any two consecutive terms are in the same ratio.

So, the test to check if a series is geometric is to compute consecutive ratios, and see if they all return the same number.

If we divide the first two terms, we have

$\dfrac{2}{4} = \dfrac{1}{2}$

If we divide the third and second terms, we have

$\dfrac{1}{2} = \dfrac{1}{2}$

Finally, if we divide the last two terms we have

$\dfrac{\frac{1}{2}}{1} = \dfrac{1}{2}$

So, all ratios return the same number. This means that the series is geometric, and the common ratio is 1/2

Answer:

25.5

Step-by-step explanation:

first find the area od the rectangle than the triangle.

to find the area count the number of squares and use A=b*h

than do the same for the triangle using A=.5*b*h

15=3*5

10.5=.5*3*7

10.5+15=25.5

X^2 - 9x -10 =0 has a discriminant of: a. 121 b. 72 c. -359 d. 41 e. 136

Feliz [49]

In the standard form of quadratic
$ax^{2} +bx+c$
the discriminant is
$b^{2} -4ac$
In your quadratic, a = 1, b = -9 and c = -10
Now you need to plug these values into the expression for the discriminant.

If john run 2.5 miles everyday, how many miles will he run in a month of 30?

Lapatulllka [165]

Answer:

2,250 miles per day.

Step-by-step explanation:

John runs 2.5 miles per day. In a period of 30 months, you can averagely take 30 days in each month.

So, 30 x 30 = 900 days in 30 months.

To find the number of miles ran in 900 days,

900 x 2.5 = 2,250 miles per day.

Hope this helps.
