Answer:

<u>Answer</u><u>:</u><u> </u><u>2</u>

Step-by-step explanation:

\frac{2}{3} (4 \frac{1}{6}  -  \frac{7}{6} ) \\

express the mixed fraction into proper fraction:

{ \boxed{4 \frac{1}{6} =  \frac{(6 \times 4) + 1}{6}   =  \frac{25}{6} }}

then solve simplify:

=  \frac{2}{3} ( \frac{25}{6}  -  \frac{7}{6} ) \\

solve the bracket:

=  \frac{2}{3} ( \frac{25 - 7}{6} ) \\  \\  =  \frac{2}{3} ( 3)

then simplify:

=  \frac{2 \times 3}{3}  \\  \\  = 2

Answer:

2.3%

Step-by-step explanation:

For continous compound interest

A=Pe^{it}

Where A is final value, P is initial investment, i is interest rate in decimal and t is period.

The time will be 30-18=12 years

Substituting $14000 for A, $7000 for P and 12 years for t

14000=7000e^{12i}\\e^{12i}=2

Introducing natural logarithms on both sides then 12i=ln 2

Making i the subject of formula then

i=ln 2 ÷12=0.05776226504666

The percentage rounded off will be 5.7% p.a

Select the correct answer from each drop-down menu. the equation from the graphed line in slope-point form using the point 2,-1
Arada [10]
The formula for point-slope form is y-a=m(x-c), where y and x are variables, a is simply one point in y, m is the slope, and c is simply one point in x. The first thing we can find is m, or the slope. This is found by dividing the change in y over the change in x. The equation for this is (I’ll plug the points in the equation)
\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{y_{1}-y_{2}}{x_{1}-x_{2}} =  \frac{-1-(-2)}{2-(-2)}=  \frac{-1+2}{2+2} =1/4

Therefore, our answer is the bottom one as our slope is 1/4.
