You'll first need to calculate the measure of angle R.  From the diagram we see that 
              opp       33
tan R = ------- = ----- = 0.589, so, using the inv. tang. function, R = 0.589 rad.    
              adj        56
                        opp                                  33
Then sin R = --------- = sin 0.589 rad = ------------------------- = 0.508 rad
                         hyp                                sqrt(33^2 + 56^2)  

                                                                                        or  29.089 degrees

Okay, don’t freak out. It’s more simple than it seems.
To find the area of this rectangle you use length x length
Let’s look for the length first
Use the bottom left and right points
(-2.25,-1) and (2.25,-1)
The length is a horizontal line so we use the x-coordinates. The distance from -2.25 to 2.25 is 4.5
Now let’s find the height. Let’s use the top left and bottom left coordinates.
(-2.25,4) and (-2.25,-1)
The height is a vertical line. The y-coordinates. Their difference is 5.
So 4.5 x 5 = 22.5

If a varies directly as b and a=3 when b=12, what is the value of a when b=18?
Zepler [3.9K]

Answer:

a is proportional to b

a=kb

k is proportionality constant

k =a/b =3/12 =1/4

k=1/4 = a/b=a/18

1/4=a/18

a=18/4 =9/2 =4.5 answer

Technician A says when there is a delay or slip as the transmission shifts into any forward gear, a slipping rear clutch is indi
blagie [28]

Answer:

Technician B

Step-by-step explanation:

It is very important that any car is taking for a test drive and a road test is carried out to check for any sort of problem with the transmission of the car or any leakages that may be found in the hydraulic circuits.

Technician B is very correct because when the hydraulic circuits is leaking, the front or forward clutch tends to slip thereby causing the shift for all forward gears to be delayed

Also,the sticking of the spool into the body of the valve can also cause the problem to occur as well.

The equation y = 0.035x shows the relationship between the grams and ounces.
scoundrel [369]
The equation y = 0.035x where x is in grams, and y is ounces, then 22 grams would be 0.035 x 22 = 0.77 ounces
