Answer:
see explanation
Step-by-step explanation:
given that r varies jointly with x and y then the equation relating them is
r = kxy ← k is the constant of variation
To find k use the condition r = 15 when x = 3 and y = 4
k = 
= 
= 1.25
r = 1.25xy ← equation of variation
When x = 16 and y = 1.25, then
r = 1.25 × 16 × 1.25 = 25
Answer:
uh can you put the pic bigger
Step-by-step explanation:
The distance between the two coordinates is 9.434
U have to do 4.50 x .30 and thats 1.35 so subtract that by original amount and its 3.15
I know you probably dont need this anymore but the answer is
1 = gerund
2= infinitive
3 = participle
hope i helped and good luck ;D
