Answer:
The constant of variation is k = -2 ⇒ (B)
Step-by-step explanation:
The equation of the direct variation is y = k x, where
- k is the constant of variation
- The constant of variation k =
The given table has 4 points (-1, 2), (0, 0), (2, -4), (5, -10)
We can use one of the points <em>[except point (0, 0)]</em> to find the value of k
∵ (-1, 2) is a given point
∴ x = -1 and y = 2
∵ k =
→ Substitute the values of x and y in the relation above
∴ k = 
∴ k = -2
The constant of variation is k = -2
No. Because no can be -1, either the solution is positive or the person wasn't born.
Answer:
1187 degrees is the difference
Step-by-step explanation:
Answer:
KL ≈ 1.94
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos48° = 
= 
= 
( multiply both sides by KL )
KL × cos48° = 1.3 ( divide both sides by cos48° )
KL = 
≈ 1.94 ( to the nearest hundredth )
Answer:
60%
Step-by-step explanation:
I changed 3/5 to 30/50, then multiplied them both by 2 to get 60/100, and since a percentage is out of a hundred, its 60%
I hope this helps! ^^
