Answer:

19.48 m

Step-by-step explanation:

The formula that is used to find arc length is:

arc length = 2πr $(\frac{angle}{360})$

In this question, r = 9m and the angle (θ) = 124°. Substitute the values into the formula.

arc length = 2 × π × 9 × $(\frac{124}{360})$

= 2 × π × 9 × 0.3444

= 19.48 m

SOLVE. integration of (1-v) /(1+v^2)

Nutka1998 [239]

$\displaystyle\int\frac{1-v}{1+v^2}\,\mathrm dv=\int\frac{\mathrm dv}{1+v^2}-\int\frac v{1+v^2}\,\mathrm dv$

The first integral is already standard and has an antiderivative in terms of $\arctan v$ . For the second integral, take $w=1+v^2$ so that $\dfrac{\mathrm dw}2=v\,\mathrm dv$ . Then

$\displaystyle\int\frac{\mathrm dv}{1+v^2}-\int\frac v{1+v^2}\,\mathrm dv=\arctan v-\frac12\int\frac{\mathrm dw}w$
$=\arctan v-\dfrac12\ln|w|+C$
$=\arctan v-\dfrac12\ln(1+v^2)+C$

Write the point-slope form of each graph. Use the red point to write your equation. State the point and slope.

Vinil7 [7]

Answer:

First Graph:

Slope = - 4/5

Point-Slope Form: y - 3 = - 4/5 (x + 2)

Point: (-2, 3)

Second graph:

Slope = 4

Point-Slope Form: y + 6 = 4 (x + 1)

Point: (-1, -6)

Step-by-step explanation:

First graph has two points: (-2, 3) & (8, -5)

Use the two points to find the slope using the Slope-Formula

Slope-Formula: y2 - y1/x2 - x1

m = slope

m = - 5 - 3/8 - - 2

m = - 8/10

m = - 4/5

The slope of the line will be - 4/5

Now for Point-Slope Form, we’ll need to use the two points with the slope to identify the Point-Slope Form of the graph

Two points: (-2, 3) & (8, -5)

Slope: - 4/5

Point-Slope Formula: y - y1 = m (x - x1)

Point-Slope Form: y - 3 = - 4/5 (x + 2)

The point will be: (-2, 3)
