On a circle of radius 10 feet, what angle would subtend an arc of length 1 feet?

1 answer:

6 0

$\bf s=\cfrac{r\theta \pi }{180}\quad 
\begin{cases}
r=radius\\
\theta=\textit{angle in degrees}\\
s=\textit{arc's length}\\
--------------\\
r=10\\
s=1
\end{cases}
\\\\\\
1=\cfrac{10\cdot \theta\cdot \pi }{180}\impliedby \textit{solve for }\theta$

Answer:

The 6% simple interest account earns more interest in 2 years.

Step-by-step explanation:

You can compare the multipliers in the interest formulas.

For simple interest, the amount in the account (A) starting with principal P and earning at rate r for t years will be ...

A = P(1 +rt)

For the values given, r=.06 and t=2, the multiplier is ...

1 +rt = 1 +.06·2 = 1.12

For interest compounded annually, the amount will be ...

A = P(1 +r)^t

For the given values, the multiplier is ...

(1+r)^t = (1.04)^2 = 1.0816

Since 1.12 > 1.0816, the account earning simple interest will earn more interest.

Step-by-step explanation:

sina = -√3/2

$\cos(a) = \sqrt{1 - { \sin(a) }^{2} }$

$= \sqrt{1 - { (\frac{ - \sqrt{ 3} }{2}) }^{2} }$

$= \sqrt{ \frac{4 - 3}{4} }$

$= \sqrt{ \frac{1}{4} }$

=±1/2

Since, π<a<3π/2

cos a = -1/2

$\tan(a )= \frac{ \sin(a) }{ \cos(a) }$

$\tan(a ) = \sqrt{3}$
