Both missing angles are 65 degrees because a triangle equals 180 degrees and a straight line equals 180 degrees :) I hope this helped!

Answer:

B = 65°

2 = 65°

Step-by-step explanation:

50° + 65° + B = 180°

115° + B = 180°

B = 65°

50° + 65° + 2 = 180°

115° + 2 = 180°

2 = 180° - 115°

2 = 65°

Is the equation y=2x a function

soldier1979 [14.2K]

Yes. It's a linear function.

x | y

0| 2(0) = 0

1| 2(1) = 2

2| 2(2) = 4

Anthony wants to buy CD for $400 that earns 2.5% APR and is compound quarterly. The CD matures in 3 years. Hi interest earned wi

lukranit [14]

Answer:

The correct option is: B. $30.00

Step-by-step explanation:

The formula for compound interest is.......

$A=P(1+\frac{r}{n})^n^t$ , where A= Final amount, P= Initial amount, r= rate of interest in decimal form, n= number of compounding in a year and t= time duration in years.

Anthony wants to buy CD for $400 that earns 2.5% APR and is compound quarterly and the CD matures in 3 years.

So here, $P= 400, r=2.5\%=0.025, t= 3$

As the CD is compounded quarterly, so here $n= 4$

Plugging these values into the above formula......

$A= 400(1+\frac{0.025}{4})^(^4^*^3^)\\ \\ A= 400(1+0.00625)^1^2\\ \\ A=400(1.00625)^1^2\\ \\ A= 431.053...$

So, the amount of total interest earned $= (\$431.053...-\$400)=\$31.053... \approx \$30.00(Approximately)$

[PLEASE ANSWER] Precalculus Question (has 2 parts)

artcher [175]

Part I

$\bf \begin{array}{l|lllllll}
x&2&\boxed{4}&6&8&\boxed{10}&12&14\\\\
y&1&\boxed{6}&11&16&\boxed{21}&26&31
\end{array}\implies 
\begin{array}{llll}
(4,6)\\\\
(10,21)
\end{array}\\\\
-------------------------------\\\\$

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 4}}\quad ,&{{ 6}})\quad 
% (c,d)
&({{ 10}}\quad ,&{{ 21}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{21-6}{10-4}$

part II

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\qquad 
\begin{array}{llll}
\textit{plug in the values for }
\begin{cases}
y_1=6\\
x_1=4\\
m=\boxed{?}
\end{cases}\\
\end{array}\\
\left. \qquad \right. \uparrow\\
\textit{point-slope form}$

now, the form above is the point-slope form, and that'd be the equation, you can leave it like so, or you can solve for "y", and put it in slope-intercept, same equation though.
