Let's break this up:

Radius: 19

Diameter: 38

Circumference: 119.4

So...

The area of a circle with radius 19 is 1134

A = πr2 = π(d

)2 A = C2

4π

π = 3.1415

A = area

C = circumference or perimeter

r = radius, d = diameter

SOLUTION STEPS:

Area of a circle in terms of radius:

Area = π·r2 = 3.14·192 = 1134 square cm(*)

Area of a circle in terms of diameter:

Area = π·(d

)2 = 3.14·(38

)2 = 3.14·(19)2 = 1134 square cm(*)

Area of a circle in terms of circumference:

Area = C2

4π

= 119.42

4π

= 14256.36

(4·3.14)

= 14256.36

12.56

= 1134 square cm(*)

(*) 1134.1149479459 cm, exactly or limited to the precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

Result in other units of area:

A circle of radius = 19 or diameter = 38 or circumference = 119.4 cm has an area of:

1.134 × 10-7 square kilometers (km²)

0.1134 square meters (m²)

1134 square centimeters (cm²)

1.134 × 105 square millimeters (mm²)

4.3784 × 10-8 square miles (mi²)

0.135625 square yards (yd²)

1.22063 square feet (ft²)

175.77 square inches (in²)

Bryce is looking at a map of a theme park. The map is laid out in a coordinate system. Bryce is at (2, 3). The roller coaster is

Sunny_sXe [5.5K]

Answer:

Bryce is closer to the <u>roller coaster</u> as compared to the water ride.

Step-by-step explanation:

Given :

Bryce is at point (2,3)

Roller coaster is at point (7,8)

Water ride is at point (9,1)

To find whether Bryce is closer to roller coaster or the water ride.

Solution.

In order to determine the closeness of Bryce from either of the two rides, we will need to find the distance of Bryce from each of them. We can apply distance formula in order to do so.

By distance formula to find distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ .

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between Bryce (2,3) and roller coaster (7,8) can be given as:

$d_1=\sqrt{(7-2)^2+(8-3)^2}$

$d_1=\sqrt{(5)^2+(5)^2}$

$d_1=\sqrt{25+25}$

$d_1=\sqrt{50}$

$d_1=7.07$ units

Distance between Bryce (2,3) and water ride (9,1) can be given as:

$d_2=\sqrt{(9-2)^2+(1-3)^2}$

$d_2=\sqrt{(7)^2+(-2)^2}$

$d_2=\sqrt{49+4}$

$d_2=\sqrt{53}$

$d_2=7.28$ units

Thus, we can see that Bryce is closer to the roller coaster as compared to the water ride.

I need help finding the domain and range for the graph

Taya2010 [7]

Answer:

Step-by-step explanation:

take two points to find the equation:

(0,4),(-2,0)

y= 2x+4

domain is where the equation is defined ( x inputs)

Range is the set of values that correspond with the domain(y outputs)

the domain and the range are all real number

domain(-∞,∞) , range (-∞,∞)

The table shows the annual sales revenues of different types of vehicles made by four automobile manufacturers.

Goryan [66]

Using the relative frequency concept, it is found that:

The number in the highlighted cell is: b. the revenue from sales of convertibles by Pluto Cars

The relative frequency of this vehicle category compared with the total sales revenue of Pluto Cars is: b. 0.225.

<h3>What is a relative frequency?</h3>

A relative frequency is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

The number in the cell has bounds conversible and Pluto Cars, and the table represents the amount earned, that is, revenue, hence option b is correct.

The total revenue of Pluto Cars is of $80 million, with convertibles corresponding to $18 million, hence the relative frequency is given by:

r = 18/80 = 0.225.

Write the factored form of the polynomial function with real coefficients, a lead coefficient of 1, and zeros

Kitty [74]

The factored form of the polynomial function is y(x) = (x + 3)²(x - 4)(x - 2)

<h3>How to determine the factored form?</h3>

The given parameters are:

Leading coefficient, a = 1
Zeros = -3, -3, 4, and 2.

Rewrite the zeros as:

x = -3, x = -3, x = 4 and x = 2

Set the zeros to 0

x + 3 = 0, x + 3 = 0, x - 4 = 0 and x - 2 = 0

Multiply the zeros

(x + 3) * (x + 3) * (x - 4) *(x - 2) = 0

Express as a function

y(x) = a(x + 3) * (x + 3) * (x - 4) *(x - 2)

Substitute 1 for a

y(x) = (x + 3)²(x - 4)(x - 2)

Hence, the factored form of the polynomial function is y(x) = (x + 3)²(x - 4)(x - 2)
