Yvaries jointly as x and z, and inversely as w: y=3 when x=-2, z=6, and w=12 find the constant of variation and write the equation that represents this relationship and lastly find y, when x=5, z=-4, and w=0.5 do i use this equation to find y? y=kxz/w or y=

answer: t=3

step-by-step explanation:

[2, 2.5)

(2.5, 3]

step-by-step explanation:

i think its these two not sure [2, 2.5)

(2.5, 3]

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
