Find the equation of the exponential function represented by the table below:

Leona [35]

Answer:

The exponential equation is;

y = 0.1•0.5^x

Step-by-step explanation:

Here, we want to get the exponential function represented by the table

Mathematically, the general form of an exponential function is;

y = a•b^x

By getting a and b, we have the exponential function

We can use any of the points;

Let us start with (0,0.1)

0.1 = a•b^0

anything raised to zero is 1

0.1 = a * 1

a = 0.1

Now, we have a

Let us work with the second point to get b

The point is (1,0.05)

0.05 = 0.1•b^1

0.05 = 0.1b

b = 0.05/0.1

b = 0.5

Thus, we have the equation as;

y = 0.1•0.5^x

A rectangle has a height of c^3+6c^2+2c and a width of c^2+1

Basile [38]

Answer:

$A = c^5+6c^4+3c^3+6c^2+2c$

Step-by-step explanation:

The dimensions of a rectangle are length and breadth/width

Here we are given height . Assuming it to be one of the side of the rectangle , we will do the further calculation

Hence one side is

side 1 = $c^2+1$

And the other side is

Side 2 = $c^3+6c^2+2c$

The area of rectangle = side 1 x side 2

$A= (c^2+1) \times (c^3+6c^2+2c)$

Distributing parenthesis

$=c^2c^3+c^2\cdot \:6c^2+c^2\cdot \:2c+1\cdot \:c^3+1\cdot \:6c^2+1\cdot \:2c$

$=c^3c^2+6c^2c^2+2c^2c+1\cdot \:c^3+1\cdot \:6c^2+1\cdot \:2c$

$=c^5+6c^4+2c^3+c^3+6c^2+2c$

adding similar terms

$c^5+6c^4+3c^3+6c^2+2c$

Hence Area is given by the above polynomial
