A scientist measured the width of a square flake of gold to be7.3 x 10 -4mm what is the area of the flake
irakobra [83]

The area of square flake of gold is 53.29 \times 10^{-8} \mathrm{mm}

<h3><u>Solution:</u></h3>

Given that width of square flake of gold is 7.3 \times 10^{-4} millimeter

To find : Area of square flake

Since gold flake is in shape of square, we can use area of square formula

<em><u>The formula for area of square is given as:</u></em>

area = s^2

where "s" is the length of one side

\begin{array}{l}{\text { Area of a square flake }=\left(7.3 \times 10^{-4}\right) \times\left(7.3 \times 10^{-4}\right)} \\\\ {\text { Area of a square flake }=53.29 \times 10^{8}}\end{array}

Hence , the calculated area of flake is 53.29 \times 10^{-8} \mathrm{mm}

Which is a stretch of an exponential decay function?
Marta_Voda [28]

Answer:

The correct option is C. The function f(x)=\frac{5}{4}(\frac{4}{5})^x is a stretch of an exponential decay function.

Step-by-step explanation:

The general form of an exponential function is

f(x)=ab^x

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

If b<1, then it represents a decay function and if b>1, then it represents a growth function.

Let k be a stretch and compression factor.

g(x)=kf(x)

If k<1, then it represents vertical compression and if k>1, then it represents vertical stretch.

In third function

f(x)=\frac{5}{4}(\frac{4}{5})^x

k > 1

b < 1

Therefore the function f(x)=\frac{5}{4}(\frac{4}{5})^x is a stretch of an exponential decay function.
