Cosine and secant functions are reciprocal, which means

$\mathsf{sec\,\theta=\dfrac{1}{cos\,\theta}}$

So, if $\mathsf{cos\,\theta=\dfrac{3}{8},}$ then

$\mathsf{sec\,\theta=\dfrac{1}{~\frac{3}{8}~}}\\\\\\
\mathsf{sec\,\theta=\dfrac{8}{3}\qquad\quad\checkmark}$

I hope this helps. =)

Describe in words the region of R3 reperesented by the equations or inequalities x2+y2+z2≤3

Vaselesa [24]

Answer:

The region represented by the equation is a full sphere of radius √3 centered in the origin of coordinates.

Step-by-step explanation:

In a plane xy, the equation that represents a circle with center in the origin, of radius r is

$x^2+y^2=r^2$

in R³, or a space xyz, we can represent a sphere with its center in the origin, and of radius r, with the equation

$x^2+y^2+z^2=r^2$

So, in this problem we have that

$3=r^2$

which means that the sphere has a radius of √3.

Finally, our equation is an inequality, and the sphere is equal to, and less than, the calculated radius.

Therefore, the sphere is "full" from the surface to its center.

The theme park company is building a scale model of the killer whale stadium main show tank for an investor's presentation. Each

Angelina_Jolie [31]

Since

the mock up is 6 times smaller than the actual killer whale stadium, then the

radius of the mock up would be:

radius

mock up = 70 / 6 = 11.67

Therefore

the volume of the mock up would be one fourth of the volume of a sphere since the

shape is like one fourth of a sphere.

V mock

up = ¼ * Volume of sphere

V mock

up = ¼ * 4/3 * pi * r^3

V mock

up = 0.25 * 4/3 * pi * 11.67^3

V mock

up = 1664.34

Therefore

the ratio is

Actual

volume / V mock up = 359007 / 1664.34 = 215.7

Therefore the mock up is about 216 times smaller than the

actual stadium.
