Mathematics
1 answer:
Anni [7]2 years ago
3 0

Answer:

  1)  a = 0

Step-by-step explanation:

Taking logarithms base 2, we have ...

  -3a·log2(1/8) = 3a·log2(512)

  -3a(-3) = 3a(9)

  27a -9a = 0 . . . . . . . subtract 9a

  a = 0/18 = 0 . . . . . . divide by 18

The solution is a = 0.

NO LINKS!! Explain your answers (show the support by showing the changes in x and y on your table). If the relationship is linea
sdas [7]

Answer:

<u>Linear relationship</u>: increasing or decreasing one variable will cause a corresponding increase or decrease in the other variable.

<u>Inverse relationship</u>:  the value of one variable decreases as the value of the other variable increases.

<u>Exponential relationship</u>: a constant change in the independent variable (x) gives the same proportional change in the dependent variable (y)

<u>Question 5</u>

As the x-value increases (by one unit), the y-value decreases.

Therefore, this is an inverse relationship.

The y-values are calculated by dividing 35 by the x-value.

\sf y=\dfrac{35}{x}

**I believe there is a typing error in the table and that the y-value of x = 3 should be 11.67**

<u>Question 6</u>

As the x-value increases, the y-value increases.  The y-value increases by a factor of 5 for each x-value increase of 1 unit.

Therefore, this is an exponential relationship.

\sf y=5^x
