Answer:
The sequence <u>is</u> geometric and the common ratio is 2
Step-by-step explanation:
A sequence is geometric if each term (after the first one) is equal to the term before it times some constant number, called the 'common ratio'.
Examples: 1, 2, 4, 8, 16, ... has a common ratio of 2 because 2*2 = 4, and 4*2 = 8, and so on.
Also, --> 4, 2, 1, 1/2, 1/4/ 1/8, ... has a common ratio of 1/2 because
4 * 1/2 = the next term 2, and 2 * 1/2 = the next trem 1/4, and son on.
In this case, 3 * 2 = 6
6 * 2 = 12
12 * 2 = 24
The sequence <u>is</u> geometric and the common ratio is 2
Answer: (4) 14
Step-by-step explanation:
8x - 2y if x is 3 and y is 5
8x = 24
2y = 10
24 - 10 = 14
So 8x - 2y is 14.
Answer:
823.7 m^2
Step-by-step explanation:
The ratio of the side lengths is 6/5.
The ratio of the areas is the square of the ratio of the side lengths, 36/25.
572 m^2 * 36/25 = 823.7 m^2
What changes may occur if the given dollar will be rounded off to its nearest value.
<span>There will only be 2 chances, the dollar will become smaller or bigger. Why? </span>
Because in mathematical rules of rounding off numbers:
number below 5 will be round down and 5 and up will be rounded up.
For example:
You have a bill of $6.79 since the number next to the decimal point in the right is 7, it will be rounded up to $7.
<span>But if your bill is $6.25, it will be rounded down to $6.00

I got this from a different brainy member
If you plug in the x and y, you get
7(1)(3)
7 x 1 x 3 = 21, so the answer is 21
