Answer:

9/2

Step-by-step explanation:

4 {x}^{2}  = 81 \\  {x}^{2}  =  \frac{81}{4}  \\ x =  \frac{ \sqrt{81} }{ \sqrt{4} }  \\ x =  \frac{9}{2}

The radius of a square is 16 cm what is the area
sdas [7]
Radius is normally used for a circle
in a circle, radius is the distance form the center of the circle to the outer edge of the circle
area=legnth times width or in square area=legnth times legneth
since this is a square and this is a math problem, we will assume that radius=1/2legnth  so
if radius=16 then legnth =2 times 16=32
area=32 times 32=1042

area=1042 square cm or 1042 cm^2

The function V(t)=1,000(1.06)^t models the value of an investment after t years. What does the ".06" represent in the function?
slamgirl [31]

Answer:

A

Step-by-step explanation:

Looking at the function, we have;

V(t) = 1,000(1.06)^t

Mathematically, the amount earned on an investment that offers a particular constant percentage return to a particular number of years can be written as;

V = I(1 + r)^t

where V is the value of the investment after some certain number of years

I is the initial amount invested

r is the constant percentage increase

and t is the number of years.

Let’s now re-write what we can deduce in the question.

This is;

V(t) = 1000(1 + 0.06)^t

Thus what this 0.06 represents is r which is the constant interest rate
