Solve the equations involving exponents


1. Solve 5^4x5^8=?

2. 11^18/11^-4=?

Answers

Answer 1
When you multiple same numbers with different exponents, the exponents add. Example x^2 * x^3 = x^4
When you divide same number with different exponents, the number subtracts

1. 5^4 * 5^8 = 5^12
2. 11^18/ 11^-4 = 11^22

how long will a section of a railroad track be if it rises 6.8m for a run of 125.6 m

Answers

Answer:

The length of the section will have 125.8 m

Step-by-step explanation:

Right Triangle

The section of the railroad track rises a height of h=6.8 m for a horizontal run of x=125.6 m.

The height and the horizontal run are the legs of a right triangle which hypotenuse L is the required length of the section of the railroad track.

Applying Pythagora's Theorem:

[tex]L^2=h^2+x^2[/tex]

[tex]L^2=6.8^2+125.6^2[/tex]

[tex]L^2=46.24+15775.36=15821.6[/tex]

[tex]L=\sqrt{15821.6}=125.8[/tex]

The length of the section will have 125.8 m

Hope this helps
(-2,8) and (3,-7) are the points that i chose to find the slope with.
you subtract y2 and y1 and put that over x2 minus x1. this is how you find the rise over run. and then you divide the rise by the run. so rise over run for this equation is -15/5. divide that and you get your slope, -3

answer: -3

Does this graph show a function? Explain how you know.​

The graph shown above does not represent a function.

How to Identify a Graphed Function?

If the curve of the graph is to the right or left, it does not represent a function because an x-value will have only two different y-values that corresponds to it, which is not a characteristic of a function.

The graph shown has the curve with the tip to the right, this means, for example, x-value of 5 has two different y-values of -4 and 4.

Therefore, the graph is not a function.
