Answer:
lim(x---->0) = -5
Step-by-step explanation:
first: sin(x-π/2)= -cosx
so the equation will be :
lim(x---->0) = [-6cos(ax)-1}/cosx
solve :
lim(x---->0) = [-(6cos(a(0))-1}/cos(0)
cos0=1
lim(x---->0)=(-(6(1)-1)/1
lim(x---->0)=-6+1/1
lim(x---->0)=-5
The answer I think 174 degrees.
90 degrees. Looking at a clock, 12 o'clock going all the way around and back is a 360 degree spin. So 12, 3, 6, and 9 are all 1/4 of a 360 degree spin. If you divide 360 by, you would get a 90 degree turn for each of those numbers mentioned above.
We have the equation f(x)=6x-5 to start with
Now in order to answer the question we have to know that f(5) is the same thing as setting x=5 and solving for f(5)
(A) f(5) = 6(5) - 5 = 30 - 5 = 25
(B) f(-3) = 6(-3) - 5 = (-18) - 5 = -23
So f(5) = 25 and f(-3) = -23
He should have $5.25 left to spend on a card.
