Which of the following is the general term for the sequence

Mathematics

7 0

This is an example of a geometric sequence.  To find for the nth term, we use the formula:

an = a1 r^(n – 1)               ---> 1

Where:

a1= 1st term of the sequence = -a

r = common ratio

To find for the common ratio r, we divide the 2nd term with the 1st term (we can also divide the 3rd term with the 2nd term; we can use any 2 terms as long as they are in succession.)

r = a^2 / -a

r = -a

Substituting a1 and r in equation 1:

an = -a (-a)^(n-1)

Therefore the answer:<span> <span>B) -a(-a)n-1</span></span>

Which expression is equivalent to (18)2⋅(19)2
sladkih [1.3K]

The expression that is equivalent to the given expression where the expression is given as (18)2⋅(19)2 is (18 * 19)^2

<h3>How to determine which expression is equivalent to the given expression? </h3>

The expression is given as

(18)2⋅(19)2

Rewrite the above expression properly

So, we have

(18)^2 * (19)^2

The factors in the above expression have the same exponent.

So, the expression can be rewritten as

(18 * 19)^2

Hence, the expression that is equivalent to the given expression where the expression is given as (18)2⋅(19)2 is (18 * 19)^2

Order the following integers from least to greatest.-41, -53, -73, -78 A. -78, -53, -73, -41 B. -78, -73, -41, -53 C. -73, -78,
irakobra [83]

The value of negative integers decreases the further we get from the 0 point on the number line.

Therefore, if we arrange the numbers in ascending order ignoring the negative sign, the numbers will be in descending order when the negative sign is included.

By the definition above, we can say that the smallest number of the lot is -78 and the largest one is -41.

The numbers can be ordered from least to greatest as shown below:

-78,-73,-53,-41

OPTION D is the correct answer.

Rectangle ABCD has vertex coordinates A(–1, –1), B(–1, –3), C(–4, –3), and D(–4, –1). It is translated 4 units to the right and
Vera_Pavlovna [14]

the translation takes the point A ( -1, -1)  to (-1+4, 1) =  (3, 1)

The refection in y = x  'flips' the points so  (3, 1) becomes  (1, 3) = A"

Do the same procedure for the other points to get the answer

(you should get B" =  (-3, 3) )
