Hope this helps!

Answer:

a) h'(t)= (6cos3t,-9sin3t,3 $\sqrt[]{5}$ cos3t)

b) t=0.93994736+πn/3

c) Magnitude of h(t) is 3 which is a constant, so h(t) lies on a sphere

In x^a=y, y^b=z, z^c=x, then prove that abc=1

Marysya12 [62]

Step-by-step explanation:

Let, x^a =y......(1) and

y^b =z.....(2) and

z ^c =x......(3).

Now, using (1) in (2) we get,

x ^ab =z......(4).

Now, using (4) in (3) we get,

x ^abc =x

or, x ^abc =x ^1

or, abc=1.

Hope it will help :)

One number is 5 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 779,

AlladinOne [14]

Answer:

Step-by-step explanation:

x - the first number

One number is 5 times a first number:

5x - "one" number (the second number)

A third number is 100 more than the first number:

x + 100 - the third number

x + 5x + x+100 - the sum of the three numbers

x + 5x + x+100 = 779

-100 -100

7x = 679

÷7 ÷7

x = 97

5x = 5•97 = 485

x+100 = 97 + 100 = 197

Check:

97 + 485 + 197 = 779
