The trajectory of a flying saucer is given by the vector function r(t) = (5 sin(t))i + (5 cos(t))j + 12tk for t ≥ 0 where coordi
Kipish [7]

Answer:

t0 = 2

Step-by-step explanation:

r' = <5cost,-5sint,12>

ds = \sqrt{25cos^{2}t+25sin^{2}t+12^2} = \sqrt{25+144} = 13 dt

So, we want

\int\limits^x_0 {13} \, dt = 26

For the problem below, θ is a central angle in a circle of a radius r. Find the length of arc s cut off by θ.
mixas84 [53]

Answer:

Here, we will use the formula from trigonometry which defines a radian

we know that an angle is a radian when the length of the radius of the circle is equal to the length of the arc formed

hence, if the radius is r and the arc is r, the angle (in radians) will be 1

if the radius is r and the arc is 2r, the angle in radians will be equal to:

length of arc / radius = 2r/r = 2 radians

I believe this will explain what is actually happening in these type of questions

So, the equation:

Θ(in radians) = s / r (where the length of arc is s and the radius is r)

π/4 = s / 12

s = 3π or 9.42 inches

What is a circumference of a smaller circle the raduis of a smaller circle 3inch and the the raduis of a larger is circle is 7so
Art [367]

Answer:

18.85 inches.

Step-by-step explanation:

We have been given that the radius of a smaller circle 3 inch. We are asked to find the circumference of smaller circle.

We know that circumference of a circle is equal to 2\pi r, where r represents radius of circle.

\text{Circumference of smaller circle}=2\pi (3\text{ inches})

\text{Circumference of smaller circle}=6\pi\text{ inches}

\text{Circumference of smaller circle}=18.84955592\text{ inches}

\text{Circumference of smaller circle}\approx 18.85\text{ inches}

Therefore, the circumference of smaller circle is approximately 18.85 inches.
