what are the missing numbers?
crimeas [40]

Given:

The table of values of an exponential function.

To find:

The missing values in the exponential function.

Solution:

The general exponential function is defined as:

y=a(b)^x              ...(i)

Where, a is the initial value and b is the growth factor.

First point from the given table is (1,10). It means, the equation (i) must be true for (1,10).

10=a(b)^1             ...(ii)

Second point from the given table is (2,20). It means, the equation (i) must be true for (2,20).

20=a(b)^2             ...(iii)

Dividing (iii) by (ii), we get

\dfrac{20}{10}=\dfrac{a(b)^2}{ab}

2=b

Putting b=2 in (ii), we get

10=a(2)^1

\dfrac{10}{2}=a

5=a

Putting a=5,b=2 in (i), we get

y=5(2)^x

The required exponential function for the given table of values is y=5(2)^x. So, the missing values are 2 and x, where 2 is in the base and x is in the power.

Round 8,937.2546 to the nearest<br> hundred.
xeze [42]

Answer:

8,900

Step-by-step explanation:

Given Number: 8,937.2546

Determine the two consecutive multiples of 100 that bracket 8,937.2546

8,937.2546 is between 8,900 and 9,000

8,950 is the midpoint between 8,900 and 9,000

As illustrated on the number line, 8,937.2546 is less than the midpoint (8,950)

Therefore, 8,937.2546 rounded to the nearest hundred = 8,900
