Answer:

A. -1/8x + 3/16

Step-by-step explanation:

-1/2(1/4x - 3/8)

Distribute the -1/2 into both the terms in the equation.

-1/2 * 1/4x = -1/8x

-1/2 * -3/8 = 3/16

Now combine both the expressions.

This makes your answer A,

If the diameter of a circle is 6 inches, how long is the arc subtended by an angle measuring 70°?

yaroslaw [1]

Since the diameter of the circle is 6 inches, then the radius will be half that, or 3 inches,

$\bf \textit{arc's length}\\\\
s=\cfrac{r\pi \theta }{180} \quad 
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad degrees\\
------\\
r=3\\
\theta =70
\end{cases}\implies s=\cfrac{3\cdot \pi \cdot 70}{180}\implies s=\cfrac{7\pi }{6}$
