can i see the numbers
Step-by-step explanation:
there is no picture
Answer:
x=7
Step-by-step explanation:
X = # adults
y = # children
system
24x+16y=$10272
x + y =532
If the prize table takes a break every 20 minutes it should eventually get a break in an hour
The refreshment table get a break every 30 minutes so it will take a second break in an hour
At 60 minutes they will be able to have a break together
Well, by definition, the tangent vector is the vector that is the result of differentiating every component of the function. Hence, the tangent vector is T=(3,-5sint,5cost). This has a magnitude of
which yields |r|=
(by using the known trigonometric formula
that holds for all t). Thus, the unit tangent vector t is given by: t=
. Now, to find a normal unit vector, we just need to find a normal vector N and scale it appropriately. To find a normal unit vector, we can just find vector that satisfies V*T=0 (dot product of vectors). By inspection, we see that the vector N=(0, cost, sint) satisfies this requirement and that it is also a unit vector (due to the aforementioned trigonometric identity). Hence, a normal unit vector to our vector function is N.
