Which is a factor of 54xy + 45x + 18y + 15?

Korvikt [17]

Upon slight rearrangement...

54xy+18y+45x+15 now factor 1st and 2nd pair of terms

18y(3x+1)+15(3x+1) which is equal to

(18y+15)(3x+1) and you can further factor the first binomial factor

3(6y+5)(3x+1)

The function f(t) = 7 cos(pi over 4t) + 12 represents the tide in Light Sea. It has a maximum of 19 feet when time (t) is 0 and

lord [1]

The function f(t) = 7 cos(pi over 4t) + 12 represents the tide in Light Sea. It has a maximum of 19 feet when time (t) is 0 and a minimum of 5 feet. The sea repeats this cycle every 8 hours

To find the height of the tide after 2 hours, we plug in 2 for t and find out f(2)

$f(t) = 7 cos(\frac{\pi}{4})t+ 12$

$f(2) = 7 cos(\frac{\pi}{4})*2+ 12$

$f(2) = 7 cos(\frac{\pi}{2})+ 12$

We know that cos (pi/2) is 0

$f(2) = 7 (0)+ 12$

So f(2)= 12

After two hours, the height of the tide is 12 feet
