1. write the following value in scientific notation: 23,000,000

2.3 by 10^7

Step-by-step explanation:

We want this rewritten in the form 2.3*10^n.

To get the decimal point in 23,000,000 between the 2 and 3, we must move it 7 places to the left, and then compensate for this by multiplying 2.3 by 10^7.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
