What is the approximate length of arc s on the circle below? use 3.14 for . round your answer to the nearest tenth. 14.1 in. 22.

Maksim231197 [3]

I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
PLEASE SEE ATTACHED IMAGE.

The length of an arc, by definition is given by:
s = R * theta
Where,
R: radio
theta: angle of the bow.
We then have to replace:
s = (6) * (135 * (pi / 180))
s = 14.1 in
Answer:
The length of the arc s is:
s = 14.1 in

given y>0 and dy/dx=(3x^2+4x)/yif the point (1,√10) is on the graph relating x and y, then what is y when x=0

jonny [76]

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{3x^2+4x}y\iff y\,\mathrm dy=(3x^2+4x)\,\mathrm dx$
$\implies\displaystyle\int y\,\mathrm dy=\int(3x^2+4x)\,\mathrm dx$
$\implies \dfrac12y^2=x^3+2x^2+C$

When $x=1$ you have $y=\sqrt{10}$ , so

$\dfrac12(\sqrt{10})^2=1^3+2(1)^2+C\implies 5=1+2+C\implies C=2$

and so the particular solution to the ODE is

$\dfrac12y^2=x^3+2x^2+2$

Then when $x=0$ , you get

$\dfrac12y^2=0^3+2(0)^2+2=2$
$\implies y^2=4$
$\implies y=2$

where we omitted the negative root because it's given that $y>0$ .

Find the missing angles for each problem, given that lines a and b are parallel (step by step)

marshall27 [118]

Answer:

1) 40°

2) 140°

3) 140°

5)40°

6)140°

7)140°

8)40°

Step-by-step explanation:

1 = 40 ° [Vertically Opposite angles are equal]

8 = 40 ° [Corresponding Angles are equal]

5 = 8 = 40° [Corresponding Angles are equal]

7 = 180° - 40° = 140° [Supplementary angles sum 180°]

6 = 140° [Vertically Opposite angles are equal]

2 = 140° [Corresponding Angles are equal]

3 = 140 ° [Vertically Opposite angles are equal]

My sis needs help asap

Alika [10]

Answer:

3/4 - 5/12

Step-by-step explanation:

first you make the demoninators the same so 3*4=12

and if you *3 you do it to the numerator

so its 9/12-5/12

the unsimplified fraction is 4/12

if wanted simplified version its 1/3
