An investment of $450 increases at a rate of 6.5% per year. What is the growth factor, b?
Alina [70]
\bf \qquad \textit{Amount for Exponential Growth}
\\\\
A=P(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &450\\
r=rate\to 6.5\%\to \frac{6.5}{100}\to &0.065\\
t=\textit{elapsed time}\\
\end{cases}
\\\\\\
A=450(1+0.065)^t\implies A=450(\stackrel{growth~factor}{1.065})^t

If a right triangle, the acute angles measure x+15 and 2x degrees. What is the measure of the smallest angle of the triangle?
saveliy_v [14]

Answer:

The measure of the smallest angle of the triangle is  40.

Step-by-step explanation:

A right triangle adds up to 180

x+15+2x+90=180

Combine like terms

3x+105=180

Subtract both sides by 105

3x+105=180

   -105=-105

___________

3x=75 Divide by 3

x=25

Plug in 25 for x for equation expression

90=90

25+15=40

2(25)=50

Therefore for the smallest angle is 40

Hope this helps

Simplify this problem
Murrr4er [49]
\dfrac{49 -  \frac{1}{r^2} }{7 -  \frac{1}{r} }

Rewrite the fraction as division:
=  (49 -   \dfrac{1}{r^2})  \div  (7 -  \dfrac{1}{r} )

Make them into single fraction:
=  \dfrac{49r^2 - 1}{r^2}  \div  \dfrac{7r - 1}{r}

Change the divide fraction into multiplication fraction:
=  \dfrac{49r^2 - 1}{r^2}  \times  \dfrac{r}{7r - 1}

Factorise the difference of square a² - b² = (a + b) (a - b) :
=  \dfrac{(7r+ 1)(7r - 1)}{r^2}  \times  \dfrac{r}{7r - 1}

Cancel the common factors:
=  \dfrac{(7r+ 1)}{r}
