Answer:
( -3 , -4 )
Step-by-step explanation:
Answer:
36. m = (3/2)n
37. s = 5tv
38. c = 3/d
Step-by-step explanation:
Each of the variations in these problems has its own associated equation. You only need to make use of the given values to find the constant of variation (k) and fill in the equation.
- direct variation: y = kx; k = y/x
- joint variation: z = kxy; k = z/(xy)
- inverse variation: y = k/x; k = xy
_____
36. The constant for direct variation is the ratio of the given values:
k = m/n = 18/12 = 3/2
Then the equation for the direct variation is ...
m = (3/2)n
___
37. The constant for the joint variation is the expression ...
k = s/(tv) = 8/((4/5)·2) = 8/(8/5) = 8·5/8 = 5
Then the equation for the joint variation is ...
s = 5tv
___
38. The constant for the inverse variation is the product of the given values:
k = cd = (1/4)(12) = 3
Then the equation for the inverse variation is ...
c = 3/d
Supplementary means they equal 180 when added. Therefore:
X+56+3x=180
Combine common units
4x+56=180
Subtract 56 from both sides
4x=124
Divide by 4
X=31
Now we know the smaller angle is 31 degrees. Now we plug that into the larger angle:
3(31)+56
93+56
149
The larger angle is 149 degrees.
I hope this Helps!
