Answer:

Hi!

The second graph corresponds to ƒ(x) = 2√x.

Step-by-step explanation:

First, √x for x < 0 does not have solutions on reals numbers.

For example:

x = -4, √-4 does not have solution because (-2)*(-2) = 4 and 2*2 = 4.

The table for ƒ(x) = 2√x

f(0) = 2√0 = 2*0 = 0

f(1) = 2√1 = 2*1 = 2

f(2) = 2√2 = 2*1.41 = 2.82

f(3) =2√3 = 2*1.73 = 3.46

f(4) =2√4 = 2*2 = 4

f(5) =2√5 = 2*2.23 = 4.46

A blazer cost $38 and you pay $39.90. how much is the sales tax rate

geniusboy [140]

To find the percentage, you divide the new price ($39.90) by the original price ($38), and the multiply it by 100 to change the answer from a decimal to a percentage:

39.90 / 38 x 100 = 105

So 39.90 is 105% of 38

To get our final answer, subtract this by 100%

105 - 100 = 5%

ANSWER: So the percentage increase of the price is 5% ($1.90)
