Given matrix D below, which matrix represents -5D?

1 answer:

5 0

Answer: option D

-5D means multiply all the elements of D by -5
i.e. -5 * -10 = 50
-5 * 10 = -50
-5 * -5 = 25
-5 * 15 = -75

The circumference of the ferris wheel at the county fair is 78.5 feet. what is the diameter in feet? Round to the nearest hundre

-Dominant- [34]

$\bf \textit{circumference of a circle}\\\\
C=2\pi r\qquad 
\begin{cases}
diameter=d\\
r=radius=\frac{d}{2}\\
----------\\
C=78.5\\
\end{cases}
\\\\\\
 78.5=2\pi r\implies 78.5=2\pi \cdot \cfrac{d}{2}$

solve for "d"

S= 2pier^2 + 2pierh , solve for h

maw [93]

$2pier^2+2pierh=S\ \ \ |subtract\ 2pier^2\ from\ both\ sides\\\\2pierh=S-2pier^2\ \ \ \ |divide\ both\ sides\ by\ 2pier\\\\\boxed{h=\dfrac{S-2pier^2}{2pier}\ other\ form\ h=\dfrac{S}{2pier}-r}$
