Answer:

32,322,237 million or 3.23million

Step-by-step explanation:

Nevada has the fastest-growing population according to the U.S. Census bureau. In 2004, the population of Nevada was 2.62 million and increasing at an annual rate of 3.5%. What is the expected population in 2010? Apply the population growth formula N=Noe^rt

Applying the formula given above

N=Noe^rt

No = 2.62 million

r = 3.5% = 0.035

t = 2010 - 2004 = 6 years

N = 2.62 × e^6 × 0.035

N = 3.2322365171 million

= 32,322,237 millon

Approximately = 3.23 millon

Answer:

Slope = 3

Y-intercept = -2

Step-by-step explanation:

Points on the line: (0, -2) and (1,1)

Slope:

m=(y2-y1)/(x2-x1)

m=(1+2)/(1-0)

m= 3/1

m = 3

Slope-intercept:

y - y1 = m(x - x1)

y + 2 = 3(x - 0)

y + 2 = 3x

y = 3x - 2

y = mx + b, where

m = slope

b = y-intercept

Answer:

area of shaded portion = 226.09 m²

Step-by-step explanation:

area of circle = πr² = (3.14)(18.6²) = 1086.314 m²

area of 123° segment = (123/360)(1086.314) = 371.157 m²

cos 61.5° = height/18.6 = 8.875

height of triangle = 8.875 m

sin 61.5° = 1/2base/18.6 = 16.346,   base = 32.692 m

base of triangle = 32.692 m

area of triangle = 1/2bh = 1/2(8.875)(32.692) = 145.071 m²

area of shaded portion = 371.157 - 145.071 = 226.09 m²

Step-by-step explanation:

So our m = (4+1)/(3+2) = 1

4 = -2 + b

b = 6

y = x + 6

Answer:

841.6 ft

Step-by-step explanation:

Solve this using the quadratic formula.

y=-16x^2+212x+139 becomes -16x^2 + 212x + 139.  The x-value of the axis of symmetry is

       -212

x = ----------- = 6.625  (This time measurement is in seconds.)

       2(-16)

The maximum height reached by the rocket is the y value when x = 6.625 and is y(6.625) = 841.6 ft

Answer:

[tex](x - 2)^{2} + (y - 3)^{2} = 36[/tex] is the equation of the circle

Step-by-step explanation:

[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex]   where (h, k) is the center and r is the radius

In this case h = 2 and k = 3 and r = 6 (see below)

r adius =

[tex]\sqrt{(2 + 3)^{2} + (3 - 6)^{2} } \\= \sqrt{5^{2} + (-3)^{2} } \\= \sqrt{25 + 9\\}\\ = \sqrt{36} = 6[/tex]

Therefore,  [tex](x - 2)^{2} + (y - 3)^{2} = 36[/tex] is the equation of the circle

The point (- 3, 6) is on a circle with a center at (2, 3) So, the equation of the circle will be (x-2)^{2} +(y-3)^{2}= 6^{2}.

The general equation of a circle of radius represents all the points that lie on the circumference of the given circle.

The general equation of a circle is:

[tex]\rm (x-h)^{2} +(y-k)^{2}= r^{2}[/tex]

where (h, k) is the center and r is the radius

The point (- 3, 6) is on a circle with a center at (2, 3).

here, h = 2 and k = 3

[tex]\sqrt{(2+3)^{2} +(3-6)^{2}} \\\\\sqrt{5^2+3^2} \\\\\sqrt{36} \\\\6[/tex]

therefore, the radius is 6 units.

Now, the equation of a circle is:

[tex]\rm (x-h)^{2} +(y-k)^{2}= r^{2}[/tex]

[tex]\rm (x-2)^{2} +(y-3)^{2}= 6^{2}[/tex]

Answer:

Brittany is 15 years old

Step-by-step explanation:

The way we get the answer is by getting the age of Alyssa 45-15=30 as, Jazmin is 15 years older than Alyssa and then we can see that Alyssa is twice as old as Brittany so we divide Alyssa's age by two. 30÷2=15 and we get Brittany's age which is 15 years old.

Answer:

360°

explanation:

the sum of interior angles of all quadrilaterals (polygons with four sides) is 360°. If you put a pen at any of the four corners and try to draw a line to any other corner, you'll find you can only make two triangles. And since the angle sum of triangles is 180°, 180 times 2 = 360

5 x 12 x 7 x 11 x 5 x 4 x 8

Answer:

y - 2 = (-1/4)(x - 8)

Step-by-step explanation:

The slope of the given line is 4.  The slope of any line perpendicular to the given line is the negative reciprocal of 4, which is -1/4.

Use the point-slope formula:

y - k = m(x - h), where (h, k) is the given point.

Then:  y - 2 = (-1/4)(x - 8)

Answer:

y = -14x + 61

Step-by-step explanation:

y = mx + b

First, we can find the slope by reading the question and plugging in the slope of -14 into a slope-intercept formula.

y = (-14)x + b

Now, we need to find the "b" value. We can plug anything we want in for x and y here, but we want the equation for the line that passes through the the point (4,5). Plug in 4 into the x value and 5 into the y value, and solve for b.

5 = (-14)(4) + b

(Flip the equation, so we can solve for b.)

b = 5 - (-14) (4)

(Multiply.)

b = 5 - -56

(Substitute the double minus for a plus sign and add.)

b = 5 + 56

b = 61

Now, plug in your "b" value into our original equation.

y = -14x + 61

Answer:

[tex]-1[/tex]

Step-by-step explanation:

This is a really nice line that goes through a lot of grid points (where the lines intersect).

One easy way to find the slope is the phrase "rise over run."  "Rise" is the name for vertical motion from point-to-point.  "Run" is the name for horizontal motion from point-to-point.

Pick two easy points on the line, say (0, 0) and (1, -1).

If you go from (0, 0) to (1, -1), the rise is -1 -- because you went DOWN 1 unit.

The run is 1 -- because you went RIGHT 1 unit.

[tex]\frac{\text{rise}}{\text{run}} =\frac{-1}{1} =-1[/tex]

The slope is -1.

Cool fact:  You'll get the same value if you use any two points on the line.

Answer:

40.35

Step-by-step explanation:

to find the amount without tax:

97 x .6 (60%) = 58.2 (the amount that will be taken off)

so 97 - 58.2 = 38.8 (the amount the pole will be WITHOUT tax)

to find the tax:

38.8 (sale price) x .04 (4 percent) = 1.552, rounded 1.55

to find full price:

38.8 (sale price) + 1.552 or 1.55 (tax) = 45.352 or 40.35

Answer:

Explanation:

For first place, we have 11 choices

Answer:

V = 497.8 cm^3

Step-by-step explanation:

Thats Righttt

The volume of the cone is 1592.6 cm³

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.

The right circular cone's vertex is immediately above the base's centre. The line connecting the vertex with the centre point of the base is perpendicular to the cone's radius. A cone, on the other hand, can have its vertex anywhere.

Given that, a right circular cone with the height of 19.4 cm and a base with a diameter of 9.9 cm. we need to find the volume,

Volume of cone = 1/3 × π × radius² × height

= 1/3 × 3.14 × (9.9/2)² × 19.4

= 1592.6 cm³

Hence, the volume of the cone is 1592.6 cm³
