Significant figures and decimal places are different things. If this were to be rounded to 2 DP you would be right, however Significant figures are to do with units. In this case, it would be 12cm^2

hodyreva [135]

Answer:

  • $3623.26

Step-by-step explanation:

<u>Given</u>

  • Each deposit = $1500
  • Interest rate= 5%
  • Time = 4 years
  • Compound number = annual

<u>Simple interest account</u>

  • B = 1500*(1 + 4*0.05) = 1500*1.2 = $1800

<u>Compound interest account</u>

  • B = 1500*(1 + 0.05)^4 = $1823.26

<u>Total balance</u>

  • $1800 + $1823.26 = $3623.26

Which function has the same domain as y= 2√x?<br> Oy= √2x<br> O y=2³√x<br> 0₁y = √x-2<br> O y=³√x-2
dybincka [34]

The option first is correct because  y= 2√x and y= √2x have same domain which is x ≥ 0.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

y= 2√x

From the above function the domain should be:

x ≥ 0 (because square root of negative values does not exist)

The function:

y = √(2x)

2x ≥ 0

x ≥ 0

Thus, the option first is correct because  y= 2√x and y= √2x have same domain which is x ≥ 0.
