Write an
equation for the circle with centre (0,0), if (12,5) lies on its circumference

Answers

Answer 1

Answer:

x² + y² = 169

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

Given (12, 5 ) lies on the circumference , then the point will satisfy the equation.

Substitute (12, 5 ) into the equation

12² + 5² = r²

144 + 25 = r²

169 = r²

Then equation of circle is

x² + y² = 169

Answer:

213.7°

Step-by-step explanation:

The bearing of B from D is angle ADB,  Thus, ∠ADB = arctan(30/45) ≈ 33.7°

The bearing of D from B is that angle plus 180°, Thus, 180° +33.7° = 213.7°

the base of a triangle is five less than twice it’s height, if the area of the triangle is 6 cm^2, find the length of the base

Answers

Answer:

Base = 3 cm

Step-by-step explanation:

Area of a triangle =  [tex]\frac{1}{2} bh[/tex]

Let h = height

base =  2 times the height - 5; b = 2h-5

Area = 6 cm²

 A = [tex]\frac{1}{2}bh[/tex]

[tex]6 =\frac{1}{2}(2h - 5)(h)[/tex]             Multiply 2h(h) -5(h)

[tex]6 (2) = 2(\frac{1}{2})(2h^{2} - 5h[/tex]      Multiply both sides by 2 to remove the fraction

 12 = 2h²- 5h

2h ² -  5h  - 12 = 0                Set the equation = 0 and factor  

(2h + 3)(h - 4) = 0

2h + 3 = 0    or h - 4 = 0

2h = -3               h = 4

h = -3/2        or   h = 4        Answer can not be negative so h = 4cm

The base is 2(4) - 5; The base = 8 - 5; base = 3 cm

Answers

y = -x + 3

Step-by-step explanation:

y = x - 3   This equation has a slope of 1

A line that would be perpendicular to the above line would then need a slope of -1

If the line has a slope of -1 and passes through (2, 1) then we can plug into

y = mx + b to get the 'b' value

1 = (-1)(2) + b

1 = -2 + b

14. The population of Booneville was 8745 in 2009, but dropped to 7913 in 2011. Find the
percent of decrease in population.

Answers

Answer:

The U.S. population 65 and older is now the largest in terms of size and percent of the population, compared with any previous census, according to a new 2010 Census brief [PDF] released today from the U.S. Census Bureau on the nation's older population. The group grew at a faster rate than the total population between 2000 and 2010.

According to the 2010 Census, there were 40.3 million people 65 and older on April 1, 2010, increasing by 5.3 million since the 2000 Census when this population numbered 35.0 million. The percentage of the population 65 and older also increased during the previous decade. In 2010, the older population represented 13.0 percent of the total population, an increase from 12.4 percent in 2000.

65 and Older Population Grew Faster than Total Population

Between 2000 and 2010, the population 65 and older grew 15.1 percent, while the total U.S. population grew 9.7 percent. The opposite happened between 1990 and 2000 when the growth of the older population was slower than the growth of the total population, with growth rates of 12.0 percent and 13.2 percent, respectively.

Population Size and Growth Varied Among the Older Age Groups

Examining the growth of 10-year age groups within the older population shows that 85- to 94-year-olds experienced the fastest growth between 2000 and 2010. This group grew by 29.9 percent, increasing from 3.9 million to 5.1 million.

Among five-year age groups in the older population, 65- to 69-year-olds grew the fastest. This age group grew by 30.4 percent, rising from 9.5 million to 12.4 million. The 65- to 69-year-old group is expected to grow more rapidly over the next decade as the first baby boomers start turning 65 in 2011.

The only older population age group to decline between 2000 and 2010 was the 75- to 79-year-old age group. This group decreased by 1.3 percent from 7.4 million to 7.3 million. The changes in this group mainly reflect the relatively low number of births during the early 1930s as fewer numbers of people entered these ages between 2000 and 2010.

What is Volume of cube?

The number of cubic units that a cube totally occupies is determined by its volume. The cubic unit of measurement for the volume of a cube includes centimetres³, metres³, inches,³ feet³, etc.

A solid three-dimensional shape with six square faces or sides is known as a cube. The total amount of space a cube takes up is its volume. The cube's square form means that all of its sides are square, and as a result, all of its edges will be of equal length. As a result, the cube's length, breadth, and height are all equal.

The formula to compute the volume of cube is a³; where 'a' is the edge of the cube.

Given:

Larger box volume = s³

smaller box volume = 12 ft³

Now, the edge of larger box = 4

So, volume of larger box

= 4 x 4 x 4

= 64 ft³

Hence, the total volume is = 64 +12 = 76 ft³

Find the slope given two points: (-9, -2) and (-5,0)

Answers

Answer:

1/7

Step-by-step explanation:

Consider the line passing through these two points.  The increase in x (run) from the first to the second is 14; the increase in y (rise) is 2.

Thus the slope of this line is m = rise/run = 2/14, or m = 1/7

Answer:

[tex]m = \frac{1}{2}[/tex]

Step-by-step explanation:

To find the slope using two given sets of coordinates, the following function can be used:

[tex]m = \frac{y2-y1}{x2 - x1}[/tex]

Where x1,y1 are one set of coordinates and x2,y2 are the other set:

[tex]m = \frac{0 - (-2)}{-5 - (-9)}\\[/tex]

[tex]m = \frac{0 + 2}{-5 + 9}[/tex]

[tex]m = \frac{2}{4}[/tex]

This can be simplified down to:

[tex]m = \frac{1}{2}[/tex]
