The function g is defined by g(x)=9k−4, where k is a constant. Find k, if the graph of g passes through the point (7,−2).

Tomtit [17]

given g(x)=9k−4 and g passes through the point (7,−2)

substiting g(7) = 9*k - 4 = -2

so 9*k = -2 + 4 = 2

k = 2/9 or 0.22

A person standing d=145 centimeters from a mirror notices that the angle of depression from his eyes to the bottom of the mirror

Serggg [28]

The length of the mirror is 64.52 cm

Explanation:

Given:

Distance of the person from the mirror = 145cm

Angle of depression = 14°

Angle of elevation = 11°

Vertical dimension of the mirror = ?

For angle of elevation:

$tan(11) = \frac{AB}{BO}\\ \\0.195 = \frac{AB}{145} \\\\AB = 28.275 cm$

For the angle of depression:

$tan(14) = \frac{BC}{BO} \\\\0.25 = \frac{BC}{145} \\\\BC = 36.25 cm$

Total length of the mirror, AC = AB + BC

= 28.275 + 36.25cm

= 64.52 cm

Therefore, the length of the mirror is 64.52 cm

If you earn $3500 per month and you expect your earnings to increase by 2.3% per year, how much do you think you will be making

Y_Kistochka [10]

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &3500\\
r=rate\to 2.3\%\to \frac{2.3}{100}\to &0.023\\
t=\textit{elapsed time}\to &10\\
\end{cases}
\\\\\\
A=3500(1+0.023)^{10}$
