Answer:

  (a)  1/2

Step-by-step explanation:

The coordinates of the point of intersection of the terminal side of angle α with the unit circle are ...

  (x, y) = (cos(α), sin(α))

When α = 60°, the x-coordinate of the terminal point is cos(60°) = 1/2.

The function h is defined by h(x)=60÷x−r, where r is a constant. Find r, if the graph of h passes through the point (−6,−20).
fomenos

Answer:

r = 10

Step-by-step explanation:

You want to find r such that ...

  -20 = 60/-6 -r

  r = 60/-6 +20 . . . . . add 20+r

  r = -10 +20 = 10

_____

If you mean h(x) = 60/(x -r), then the answer is different.

  -20 = 60/(-6-r)

  -6-r = 60/-20 . . . . . multiply by (-6-r)/(-20)

  -r = -3 +6 = 3 . . . . . add 6, simplify

  r = -3 . . . . . . . . . . . . multiply by -1

Match the formula to the correct figure.
forsale [732]

Given:

The figures cylinder, cube, cone, and pyramid.

To find:

The formula of volume for the given figures.

Solution:

Volume of a cylinder is:

V_1=\pi r^2h

Where r is the radius and h is the height.

Volume of a cube is:

V_2=a^3

Where a is side length of cube.

It is also written as:

V_2=l\times w\times h

Where l is length, w is width, h is height and l=w=h.

Volume of a cone is:

V_3=\dfrac{1}{3}\pi r^2h

Where r is the radius and h is the height.

Volume of a pyramid is:

V_4=\dfrac{1}{3}Bh

Where B is the base area and h is the height.

Therefore the table of formulae is shown below:

Figure                       Volume formula

Cylinder                   \pi r^2h

Cube                        l\times w\times h

Cone                        \dfrac{1}{3}\pi r^2h

Pyramid                    \dfrac{1}{3}Bh

The perimeter cf a rectangle i: 56 inches" the ratio of the length of the width is 6 : 1. Find the length and the width.
sergejj [24]

Answer: Length = 24; width =4

Step-by-step explanation

Since the ratio of the length to width is 6:1

Let the length  be represented as  6x

And the width be  = x

Such that that the Perimeter of the rectangle which is  

Perimeter = 2(length + width)  becomes

56 = 2(6x + x)

56/2 = 6x+x

28 = 7x

x = 4

Width = 4

Length = 6x= 6 x 4 = 24
