Answer:
k = 7
Step-by-step explanation:
given y varies jointly with x and w then the equation relating them is
y = kxw ← k is the constant of variation
to find k use the condition when y = - 42, x = 2 and w = - 3 , then
- 42 = k × 2 × - 3
- 42 = - 6k ( divide both sides by - 6 )
7 = k
constant of variation is k = 7
Letter A. Influence. Influence is a the primary example of he capability of language that is Self-fulling prophecy. It labels are attached to people and the words describe objects influence perception to them.
Use y2-y1/x2-x1
So 0-5/3-2
-5/1= m= -5
Then plug it into y=MX+B
0= -5(3)+b
0= -15+b
b=15
y=-5x+15
So I hope this helps but I'm not sure how to plug it into that's equation. The rest of my work is rigt
Answer:
Capital: 2 400
Tasa: 5% = 5/100 = 1/20
Tiempo: 4 años
A) Interés = capital*tasa*tiempo
Interés = 2400*(1/20)*4
Interés = 480 soles
B) Interés = Capital*((1 + tasa)^tiempo+1)
Interés = 2400*((1 + 1/20)^4 + 1)
Interés = 2400*((21/20)^4 + 1)
Interés = 2400*(194 481/160 000 + 1)
Interés = 2400*(354 481/160 000)
Interés = 5 317,215Step-by-step explanation:
