Suppose bug B lands on the end of the wiper blade closest to the pivot. Assume the wiper turns through an angle of 120°. In one
adelina 88 [10]

Answer:

s = 8*π in

Step-by-step explanation:

Given:

- The complete data is given in the figure (attached):

Solution:

- The bugs lands on the end of the wiper blade closest to the pivot. The arc length (s) swept by a wiper in one cycle i.e θ = 120° would be given by:

                                     s = 2*r*θ

- Where, r: The distance between the bug and the pivot = 6 in

              θ : Angle swept in radians

- The distance travelled by the bug is s:

                                    s = 2*(6)*( 120 / 180 ) * π

                                    s = 8*π in

Through the points (-1,-9) and (2,6) find the equation
vivado [14]
M= 6- -9 / 2- -1 = 6+9 / 2+1 = 15/3 = 5 
y-6=5(x-2) 
y-6=5x-10 
y=5x-4 

-9=5(-1)-4
-9=-5-4
-9=-9 

6=5(2) -4
6=10-4
6=6 

Step 1: find the slope using the formula m=y2-y1/x2-x1
Step 2: plug the slope and one point into the point-slope formula and solve to find the equation of the line in y=mx +b form.
Step 3: test both points to see if the equation works.

You are painting the outside of a 28-foot fence that goes around a square garden. There are 4 equal sections. You have painted 1
Arisa [49]
Well, to figure this out, you would have to divide 28 by 4, since there are four sections. That is 7. 7 divided by 2 is 3.5, so you would have completed 3.5 feet of the fence.

Solve for y and x<br> 2+3x-1=4y <br> And <br> 2x-3=y
Natasha_Volkova [10]

Answer:

x = 2.6, y = 2.2

Step-by-step explanation:

if 4y = 2 + 3x - 1 and

y = 2x - 3,

4y = 2 + 3x -1 and 4y = 8x - 12 so

8x - 12 = 2 + 3x - 1

so 5x - 12 = 1,

5x = 13,

x = 2.6

If x = 2.6,

y = 5.6 - 3

so y = 2.2
