How long will a sum of rs 5000 take to amount to rs 8750 at rate of 15./. per year​

sum of money(principal)=rs5000

amount=rs8750

rate=15%

to find interest use forrmula,

amount=principal+interest

rs8750=rs5000+interest

rs8750-rs5000=interest

rs3750=interest

to find time use formula,

interest=p*t*r/100

rs3750=rs5000*t*15/100

rs3750*100=rs75000*t

rs375000/rs75000=t

5=t

Step-by-step explanation:

therefore the sum of money rs5000 amount to rs8750 at the rate of 15% after 5 years

46.2+112.3

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:
