Does this graph represent a function? Why or why not?

Mathematics

Answer:

Yes, this graph represents a function.

Functions can have a maximum of one y-value for every x-value. On a graph, this means it passes the vertical line test.

Step-by-step explanation:

The vertical line test is when a vertical line is passed though the graph. If at any point the vertical line touch more than one point on the graph, the graph is not a function. Vertical line test is also known as VLT.

Nota: am folosit Google Translate așa că sper sensul nu se pierde în traducere<span>

Sunt presupunând că t, g, și c sunt constante

</span>simplifica

f(x)=cg²t²x²

amintiți-vă că derivitive de af (x), în cazul în care a este o constantă este un lucru ori mai mare decât derivitve lui f (x)

f(x)=cg²t²(x²)

<span>Amintiti-va: derivitive lui x^n este nx^{n-1}</span>

Simplify.<br> -3(w+ 3) + 4w
densk [106]

Hello! :)

To solve you equation, we will first Distribute

(-3) (w) + (-3) (3) + 4w

= -3w + -9 +4w

Now, we will combine like terms

-3w + -9 + 4w

= (-3w + 4w) + (-9)

= w + 9

Hope this helped you!

Please show me how to solve this equation step by step!<br> 1/25(20-t)=4/25t-3/5
rjkz [21]

Remark

Multiply both sides of the equation by 25. Then you have an equation that you have already done probably.

Step One

Multiply both sides of the equation by 25

1 * (20 - t) = 4t - (3/5) * 25    Every part of the equation must be multiplied by 25

(20 - t) = 4t - 75/5                 3*25/5 = 75/5

20 - t = 4t - 15                       Add t to both sides

20 - t + t =4t + t  - 15             Combine like terms

20 = 5t - 15                            Add 15 to both sides

20 + 15 = 5t - 15 + 15             Combine like terms  

35 = 5t                                    Divide by 5

35/5 = 5t/5                             Switch sides

7. A boy on ice skates has a momentum of 200 kg m/s to the left at a velocity of 20
tankabanditka [31]

Answer: 10 m/s

Step-by-step explanation:

Given

Momentum of boy P=200\ kg.m/s

Mass of boy is m=20\ kg

Momentum is the product of mass and velocity

P=mv

Substitute value

\Rightarrow 200=20\times v\\\Rightarrow v=10\ m/s

Thus, the boy is moving with a velocity of 10 m/s
