Answer:

length of arc ≈ 17.8 (to the nearest tenth)

Step-by-step explanation:

To find the length of the arc we use the formula for finding length of an arc.

length of arc = ∅/360 × 2πr

where

∅ = central angle

r  = radius

∅ = 340°

r = 3

length of arc = ∅/360 × 2πr

length of arc = 340/360 × 2 × π × 3

length of arc = 340/360 × 6π

length of arc = 2040π/360

length of arc = 204π/36

length of arc = (204 × 3.14)/36

length of arc = 640.56/36

length of arc = 17.7933333

length of arc ≈ 17.8 (to the nearest tenth)

Answer:

y = 6x - 5

Step-by-step explanation:

In order to determine the slope-intercept form, y = mx + b, of the given line:

You need to find the slope (m) and determine the y-intercept (b).  

Given the points (1, 1) and (0, -5):

Let (x1, y1) = (1, 1)

(x2, y2) = (0, -5)

Use the following formula for slope:

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

m = (-5 - 1)/(0 - 1)

m = -6/-1

m = 6

The slope of the line is 6.

Next, the y-coordinate (b) of the point, (0, b ) is the y-intercept of the line where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.

Looking at the graph, you'll see that the line crosses at point (0, -5). We used this point earlier to solve for the slope. Hence, the y-coordinate, b =  -5, is the y-intercept.

Given the slope, m = 6, and the y-intercept, b = -5:

The linear equation in slope-intercept form is: y = 6x - 5.

Step-by-step explanation:

Solution:

a. when e = 11 and f = 7

[tex] \\ \: \: \frac{e + 5}{4f - 4} [/tex]

[tex] \\ = \frac{11 + 5}{4 \times 7 - 4} [/tex]

[tex] \\ = \frac{11 + 5}{28 - 4} [/tex]

[tex] \\ = \frac{16}{24} [/tex]

[tex] \\ = { \cancel \frac{16}{{24}}}[/tex]

[tex] \\ = \frac{2}{3} [/tex]

b. when e = -1 and f = -4

[tex] \\ \: \frac{e + 5}{4f - 4} [/tex]

[tex] \\ = \frac{{ - 1 + 5} }{4( - 4) - 4} [/tex]

[tex] \\ = \frac{ - 1 + 5}{ - 16 - 4} [/tex]

[tex] \\ = \frac{4}{ - 20} [/tex]

[tex] \\ = { \cancel\frac{4}{ - 20}} [/tex]

[tex] \\ = \frac{ - 1}{5} [/tex]

Answer:

Each circle contains shapes that all share at least one characteristic. Some shapes are contained in more than one circle because they share more than one characteristic.

The distance between any point of the circle and the centre is called the radius. All these circles have one.

Answer:

∠ E = 57°

Step-by-step explanation:

Since DF = EF then the triangle is isosceles with 2 base angles congruent , so

∠ E = ∠ D = 4x + 1

The sum of the 3 angles in the triangle = 180°

Sum the 3 angles and equate to 180

4x + 1 + 4x + 1 + 5x - 4 = 180 , collect like terms

13x - 2 = 180 ( add 2 to both sides )

13x = 182 ( divide both sides by 13 )

x = 14

Then

∠ E = 4x + 1 = 4(14) + 1 = 56 + 1 = 57°
