If A(x', y') & B(x",y") the the distance AB is given by the following formula:

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

**The length of the longest metal rod that can be sent is 12 inches.**

As given, the only boxes available for shipping are 7-inch cubes. As Jorge needs to ship a thin metal rod to a metalworking shop, he will put the rods diagonally or space diagonally in the box.

The space diagonal of a cube can be found by the formula :

=

Here, x is 7 inches.

So, Diagonal is =

= inches.

Rounding this to nearest whole number we get 12.

**So, the length of the longest metal rod that can be sent is 12 inches.**

Since we are given 2 sides and 2 angles, we can use the Side Angle Side (SAS) method. The area of a triangle is given by the formula:

Area = absinC/2; where a and b are adjacent sides and C is the angle between a and b.

Area = 5*8*sin31°/2 = 10.3 square units.

Area = absinC/2; where a and b are adjacent sides and C is the angle between a and b.

Amplitude: the height of the graph from the peak to the axis. On the unit circle it would be the radius (max and min values) at 0, pi/2, 2pi

Period: the length of one full cycle of the cos graph. On the unit circle it is the circumference. The distance around a circle with radius = 1.

Domain: the x value or the values on the horizontal axis. On the unit circle these would be the radian measures around the unit circle such as pi/6, pi/4,

pi/3, pi/2.

Range: the y value or the values on the vertical axis. On the unit circle it would be the cosine value for each radian measure. Such as cos pi/4 = (sqrt2)/2, cos pi/3= 1/2.

X-intercepts: the points where the graph crosses the horizontal axis. On the unit circle these are the cosine values when theta is at the vertical points of the unit circle, pi/2 and 3pi/2.

QUESTION POSTED AT 28/03/2020 - 12:19 PM

**Answer:**

One point could be (1,1)

**Step-by-step explanation:**

1. The equation of the circle is

h and k are the (x,y) coordinates of the center of the circle respectively. In this sense, h=6 and k=1, and r is the radius of the circle which is 5. Replacing we get

2. The x-coordiante of the center of the circle is at x=6. The radius is 5, therefore, the left end of the circle is at x=1 and the right end is at x=11. This means that the circle can take x-coordiantes from 1 to 11, and for each we will have a Y-coordinate.

3. To get the Y-coordinate we isolate Y from the circle equation.

4. From the last equation, we can repalce x by any number between 1 and 11, and we will get the respective Y-coordinate, for example:

If we take x=1, replacing we get:

So, one point could be (1,1)

5. If you want to get another point, you could replace X by 2,3,4,5,6,7,8,9,10 and 11 in the previous equation, and for each one you will get a new Y-coordinate.
