Formula for scale factor

Answer:

Option C.

Step-by-step explanation:

Two trapezoids W'X'Y'Z' and WXYZ have been given in the figure attached.

Trapezoid WXYZ has been dilated to form another trapezoid W'X'Y'Z'.

We have to find the scale factor by which WXYZ was dilated.

Dilation factor = \frac{\text{Trapezoid W'X'Y'Z'}}{\text{Trapezoid WXYZ}} = \frac{W'X'}{WX}

= \frac{6}{8}

= \frac{3}{4}

Therefore, \frac{3}{4} is the dilation factor by which trapezoid WXYZ was dilated.

Option C is the answer.

Situation:A researcher in North America discoversa fossile that contains 65% of its originalamount of C-14..-ktN=NoeNo inital am
zheka24 [161]

SOLUTION

We have been given the equation of the decay as

\begin{gathered} N=N_0e^{-kt} \\ where\text{ } \\ N_0=initial\text{ amount of C-14 at time t} \\ N=amount\text{ of C-14 at time t = 65\% of N}_0=0.65N_0 \\ k=0.0001 \\ t=time\text{ in years = ?} \end{gathered}

So we are looking for the time

Plugging the values into the equation, we have

\begin{gathered} N=N_0e^{-kt} \\ 0.65N_0=N_0e^{-0.0001t} \\ e^{-0.0001t}=\frac{0.65N_0}{N_0} \\ e^{-0.0001t}=0.65 \end{gathered}

Taking Ln of both sides, we have

\begin{gathered} ln(e^{-0.000t})=ln(0.65) \\ -0.0001t=ln(0.65) \\ t=\frac{ln(0.65)}{-0.0001} \\ t=4307.82916 \end{gathered}

Hence the answer is 4308 to the nearest year

The answer is C that’s why it has a 1 pt in front <br><br> Plz just help me explain how to get that
Ierofanga [76]

First lets get the formula for a triangular prism

v =( \frac{1}{2} bh)h

First lets plug in our numbers

v =( \frac{1}{2} \times 7 \times 4)8.5

It really doesnt matter how you multiply everything, but you end up with 119cubic feet.
