Answer:

4.69 feet

Step-by-step explanation:

If the table is a square, all the sides are equal and the area is the length of one side squared. A=l^2

The length must then be the square root of the area. The square root of 22 square feet is 4.6904 feet. Rounded to the nearest tenth, that is 4.69 feet.

Identify the initial value in each formula below, and state whether the formula models exponential growth or

kaheart [24]

Answer:

Intial Value: f(t) = 2 , Exponential Growth

Step-by-step explanation:

To find the initial value, all we have to do is find the value of f(t) at t = 0

In this case the given equation becomes

$f(t) = 2(\frac{5}{3})^0$

from the law of indices we know that any number with the power 0 is equal to 1 (except 0 with the power 0)

$a^0 = 1$

hence the above equation becomes

$f(t) = 2(1)\\ f(t) = 2$

so the initial value is 2.

To find out whether this is exponential growth or exponential decay we need to see whether the base value of the power t is less than 1 or greater than 1, i.e. from

$(\frac{5}{3} )^t$

$\frac{5}{3}$ > 1 or $\frac{5}{3}$ < 1

if the value is greater, then with each increment in power, the total value will increase while if it is less than 1 then with each increment in power the total value will decrease.

Hence since $\frac{5}{3}$ > 1 then this is an exponential growth
