Does the graph represent a function?

Harrizon [31]

Answer:

The graph does represent a function because it passes the vertical line test!

Step-by-step explanation:

A vertical line test means if you put a vertical line over any area on the graph it shouldn't hit the line more than once :)

Solve for e. <br><br> g/e^2 - r = m - y

vesna_86 [32]

$\bf \cfrac{g}{e^2}-r=m-y\implies \cfrac{g}{e^2}=m-y+r\implies g=e^2(m-y+r) \\\\\\ \cfrac{g}{m-y+r}=e^2\implies \pm\sqrt{\cfrac{g}{m-y+r}}=e$

The length and width of a rectangular room are measured to be 3.955±0.005m. Calculate the area of the room and its uncertainty i

Margarita [4]

Answer:

The area of the room and its uncertainty in square meters is:

15.642±0.040 $m^2$

Step-by-step explanation:

We know the area of a rectangular room is the multiplication of the length and width:

$Area= 3.955m*3.955m\\Area= 15.642 m^2$

Now we need to know the uncertainty, the uncertainty of a multiplication is:

$\frac{δ_a}{|Area|} =\frac{δ_L}{|L|}+\frac{δ_W}{|W|}$ (1)

$δ_A$ : Area uncertainty

$δ_L$ : Length uncertainty

$δ_W$ : Width uncertainty

A: Area of the room

L: Length

W: Width

Clearing the uncertainty of the area:

$δ_A=(\frac{δ_x}{|x|}+\frac{δ_y}{|y|})*Area$ (2)

$δ_A=(\frac{0.005}{|3.955|}+\frac{0.005}{|3.955|})*15.642 m^2$

$δ_A= 0.040 m^2$

The area of the room and its uncertainty in square meters is:

15.642±0.040 $m^2$

Explain how to use estimation to help find the product of two decimals. Give an example with both estimated and actual answers.

shusha [124]

If you multiply decimals , the estimate value is necessary !

it could be understood easily, if at any place the number exceeds 4 , then the value in front is raised by one !

as;
2.234 = 2.23 , it will remain same but,
2.235 = 2.24 the 3 raised to 5 !!

if you have any problem yet , comment !!
