Determine the period of the following trigonometric function.<br> y=4cos(8πx)

Diano4ka-milaya [45]

The period of y = 4 cos(8πx) is 2π/(8π) = 1/4, since

cos(x - 2π) = cos(x)

and if we replace x with 8πx, we get

cos(8πx - 2π) = cos(8πx)

and

8πx - 2π = 8π (x - 1/4)

It takes Audrey 3/5 hour to paint 2/5 square yards of wood to be used for making shelves. How many square yards can she paint in

ivanzaharov [21]

This is how I would do it;

Convert to minutes 3/5 *60 = 36
Convert this to decimal 2/5 = 0.4

Then;

if it takes 36 mnts to paint 0.4yd^
in 60 mnts x yd^
___________________

60 x 0.4 / 36 = 0.66666667

convert back to fraction = 2/3 yd^ in 1hr

The product of some negative number and 4 less than twice that number is 286 find the number

Naya [18.7K]

Let's say that number is hmmm "a"

now.. twice "a" is 2*a or 2a
4 less than that is " 2a - 4"

now, the product of those two fellows is 286, well ok

a( 2a - 4) = 286

thus

$\bf a(2a-4)=286\implies 2a^2-4a^2=286\implies a^2-2a^2=143
\\\\\\
a^2-2a^2-143=0\implies (a-13)(a+11)=0
\\\\\\
\begin{cases}
a-13=0\implies &a=13\\
a+11=0\implies &\boxed{a=-11}
\end{cases}$
