Answer:
The answer is:
{(2,2),(4,4),(6,6),(8,8)} is a function
{(0,3),(3,5),(5,6),(8,4)} is a function
{(1,2),(3,3),(4,8),(6,3)} is a function
{(3,4),(5,2),(5,6),(7,3)} is not a function
Step-by-step explanation:
Sorry I don't have an explanation, but I know these are correct because I took the test and got this correct. ;)
1 function {(2,2),(4,4),(6,6),(8,8)} written is a function the other following coordinates are not functions due to it not being a straight line as a 'proper' function should be.
$11.34 Discounted Price Including Tax
CD is $12.00
10 percent off of 12 dollars is:
12 x .10 = $1.2
12 - 1.2 = $10.8 WITHOUT TAX!!
5/100 = 0.05
0.05 x 10.8 = .54 (Tax itself)
10.8 (Discounted price) + .54 (Tax) = $11.34 Discounted Price Including Tax
Step-by-step explanation:instead, try making the subscripts and superscripts stand out:
n-1
a = a * r
n n-1
Believe me, it's worth the extra work to do this!!
Given the sequence -3, -6, -12, -24, you can easily see that the first term,
a is -3. The common factor is 2. Note how (-3)*2=-6, and so on.
1
So, a = -3 and r=2.
So the formula for this geometric sequence is
a = -3*2
n
