Find consecutive integers that are under and over estimates of the solutions to the following exponential equations.
Art [367]

Answer:

5 and 6

Step-by-step explanation:

We have to first solve the given equation 10^{x} =432901

Now, taking log in the both sides we get,

log10^{x} = log 432901

⇒ x log 10=log 432901 {Since we have the logarithm property, log aᵇ =b log a}

⇒ x =log 432901 {Since log 10=1}

⇒ x=5.636.

Therefore, the consecutive integers that are under and over the value of x are 5 and 6. (Answer)

This table gives a few (x, y) pairs of a line in the coordinate plane.
katrin2010 [14]

Answer:

The x-intercept is : (22, 0)

Step-by-step explanation:

From the table values, we determine that it is a straight line as there is a constant change in x and y values.

i.e.

Any previous value of y can be obtained by subtracting 15 from the successor y value.

i.e.

60 - 15 = 45

45 - 15 = 30

so if continue, we can also determine some of the other values of y such as

30 - 15 = 15

15 - 15 = 0

Also, there is a constant change in x values. so, any previous value of x is obtained by subtracting 13 from the successor x value.

i.e.

74-13 = 61

61-13 = 48

48-13=35

35-13=22

So, from the above analysis, we determine that when the value of y = 0, the value of x = 22.

We also know that the x-intercept is the point where the line crosses the x-axis. At this point y = 0.

so, at y = 0, the value of x = 22.

Therefore, the x-intercept is : (22, 0)
