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.

state which basic Property of addition or multiplication justifies truth of the mathematical expressions 0+7y+2=7y+2
dlinn [17]
The given equation is:

0 + 7y + 2 = 7y + 2

This equation is showing that addition of 0 leaves the expression unchanged. 0 is known as the Additive Identity this means if we add or subtract 0 from any expression, number or equation the result won't be changed.

Therefore, the equation satisfied the property of Additive Identity of Real Numbers.

Find the distance between each pair of points
algol [13]

Answer

\sqrt{34}

Step-by-step explanation

You would use the pythagorean theorem for this problem. The point on the y-axis is 5 away from (0,0). The point on the x-axis is 3 away. You would square these, leading from

5+3 to

25+9=\sqrt{34}

Answer is \sqrt{34}.
