If the length of an arc intercepted by a central angle of 1.25 radians is 32 inches, which proportion could be used to find the

radius of the circle?
1.25/2π = 32/πr^2
1.25/360 = 2πr/32
1.25/2π = 2πr/32
1.25/2π = 32/2πr

Answer:

Option 4: 1.25/2π = 32/2πr

Step-by-step explanation:

Arc length = (theta/2pi) × 2pi × r

32 = (1.25/2pi) × 2pi × r

1.25/2pi = 32/(2pi × r)

Given:

The table of values.

Hours (h)        Dollars (d)

     1                       42

     2                      84

     3                     126

     4                     168

     5                       ?

To find:

The correct statements about the table.

Solution:

From the given table it is clear that,

1\times 42=42

2\times 42=84

3\times 42=126

4\times 42=168

This pattern can be defined as

h\times 42=d

Multiply h by 42 to get d. So, option A is correct.

Using this pattern, we get

5\times 42=210

The missing value in the last row is 210. So, option D is correct.

From the given table it is clear that the rate of change is $42 per hour because dollar is increasing by 42 in every hour.

A real-world situation that is represented in the table is “Richard is a video game designer and earns $42 per hour.”

Therefore, the option E is correct.

What is an equation of the line that passes through the points (0, 0)and (5, 2)?
beks73 [17]

Answer:

5y - 2x = 0

Step-by-step explanation:

Equation of line is given by,

y - y1 = ( x - x1 ) ( y2 - y1)/ (x2 - x1 )

y - 0 = ( x - 0 ) ( 2 - 0 )/ ( 5 - 0 )

y = 2x /5

5y = 2x

5y - 2x = 0

This is the required equation.

Write the equation of the line that passes through (6, 1), m = -3
JulijaS [17]

Answer:

y = - 3x + 19

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute (6, 1) into the partial equation

1 = - 18 + c ⇒ c = 1 + 18 = 19

y = - 3x + 19 ← equation of line

What is the approximate surface area of the sphere 15yd?
tekilochka [14]
<span>The surface area of a sphere is equal to [4 x Pi x R^2]. In other words, four multiplied by 3.14 multiplied by the radius squared. If the radius of a sphere is 15 yards, the approximate surface area is [4 x 3.14 x (15x15)] = [12.5 x 225] = [2,812 yd^2]. The surface area of a sphere with radius 15 yd is approximately 2,800 yards.</span>
