Which representation does NOT represent y as a function of x?

<h3>Answer: Choice C</h3>

Why isn't choice C a function? It's because we have the input x = 4 lead to more than one output at the same time (y = 5 and y = -5). A function must have all allowed inputs lead to exactly one output.

The diagram for choice C shows we have the points (4,5) and (4,-5). If we plotted those two points, then a vertical line forms, which will show this relation fails the vertical line test.

Choices A, B, and D do not have this happen where a certain input leads to multiple outputs at once; therefore, these are all functions. For the tables A and D, note there aren't any repeated x values. If you were to convert choice C into table form, then you would have the x value 4 repeat itself.

Answer:

The length of the line segment is of 5.9 units.

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, $(x_1,y_1)$ and $(x_2,y_2)$ . The distance between these two points is given by:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

How long is the line segment?

The distance between points P and Q. So

P(1,3), and Q(4,8).

$D = \sqrt{(4-1)^2+(8-3)^2} = \sqrt{3^2 + 5^2} = \sqrt{34} = 5.9$

The length of the line segment is of 5.9 units.

Differentiate with respect to x : 2xe^x

Gnom [1K]

$\\ \sf\longmapsto \dfrac{d}{dx}2xe^x$

Apply product rule

$\\ \sf\longmapsto \dfrac{d}{dx}2x(e^x)$

$\\ \sf\longmapsto 2x\dfrac{d}{dx}e^x+e^x\dfrac{d}{dx}2x$

$\\ \sf\longmapsto 2xe^x+2e^x$

$\\ \sf\longmapsto 2e^x(x+1)$

Can someone please help me with this square root problem?

nadya68 [22]

Answer:

x=14.87

Step-by-step explanation:

What we want to use is pythagoras theorem:

a^2+b^2=c^2, where c is the hypotenuse

10^2+11^2=x^2

221=x^2

x= $\sqrt{221}$

x=14.866...

x=14.87

The pool holds 15069 of water and is leaking at a rate of 4 gallons per day how many gallons will remain in the pool after 141 d

Veronika [31]

Answer:

Water remaining in the pool after 141 days = 14,505 gallons

Step-by-step explanation:

Total number of gallons of water in the pool = 15,069

Rate of leakage of water = 4 gallons per day

Using unitary method

1 day leakage of water from the pool = 4 gallons

∴ In 141 days leakage of water from the pool will be = $141\times4=564$ gallons

After leaking 564 gallons of water, total gallons of water that will remain in the pool will be = $15,069-564=14,505$ gallons
