u lu get after 5years.4Priyanka deposited 650She withdrew 1250 thamount will she get after two years?0 in a bank for one year. The bank pays interest at the rate of 9% per annum.mount for 2 years.Whatillafter the end of the year and deposited the remaining amount for 2 years. What

Answer»

Answer:

Step-by-step explanation:

P=6500,r=9%per annum

Amount of 1 year = rs (6500×9×1)/100

=rs(65-9)=585

Amount after 1 year = rs (6500+585)=rs 7085

Priyanka withdrew rs 1250 after 1 year

Balance amount = rs (7085-1250)

=rs 5835

Now,

Interest for next two years balance amount

= rs (585×9×2)/100=rs 1050.30

Hence,The amount after 3 years

Rs (5835+1050.30)= rs 6885.30.

3. Javed deposited 12000 rupees at 9 p.c.p.a. in a bank for some years, and withdrew hisinterest every year. At the end of the period, he had received altogether 17,400 rupees.For how many years had he deposited his money ?

Answer»

At the end of the period Javed got 17400. This means he got 12000 which he had deposited and 5400 extra as interest.

Now t he had deposited the money at simple Interest.

So his Interest came to be 5400.

According to your question, every year he gets 9 % of the principle as Interest. 9 % means he is getting 1080 Rs every year.

So if he is getting 1080 Rs every year, Then in how many years will he get 5400 Rs ?

Let's just divide 5400 by 1080 .

5400÷1080 = 5 years

Find the zwrcesof theRyno mia.x2+t-2, and vehitre 어elanon beteen-the cofficents and十heスeroes of.thelolynoma

Answer»

Here the given equation is x²+(1/6x)-2=0multiplying the above equation by 6 we get6x²+x-12=0or,6x²+9x-8x-12=0or,3x(2x+3)-4(2x+3)=0or,(3x-4)(2x+3)=0Hence the zeros of the polynomial arex=4/3 andx=-3/2

Now for a quadratic polynomialax²+bx+c=0the relation between coefficient a b and c and their roots m and n arem+n=-b/amn=c/a

For the given equationm=4/3 n=-3/2and a=1,b=1/6 and c=-2now m+n=-1/6and -b/a=-1/6therefore,m+n=-b/aalso m x n=-2and c/a=-2Hence m x n=c/a Hence the relation between the coefficients of polynomial and its roots (or zeros) are verified.

a rational number in it's decimal expansion is 327.7081. what can you say about the prime factors of q, when this number is expressed in the form of p/q? give reasons.

Answer»

If the factors of denominator of the given rational number is of form 2ⁿ 5^m ,where n and m are non negative integers, then the decimal expansion of the rational number is terminating otherwise non terminating recurring.We know that a rational number has either terminating or non terminating repeating decimal expansion.

SOLUTION:Here, 327.7081 has terminating decimal expansion so it represents a rational number.327.7081= 3277081/10000= p/qThus q=10⁴ , whose factors are 2⁴ × 5⁴.

Find the remainder when x-2x2+1 is divided by x-1

Answer»

Use remainder theorem,

So, when p(x) = x⁴ + x³ - 2x² + 1 is divided by x - 1 the remainder will be p(1).

So, p(1) = 1 + 1 - 2 + 1 = 1

So, remainder is 1

Check whether g(x)(x-3) is a factor of p(x)(x^3 + 7x^2 +3x-6)

Answer»

if we put x=3 in p(x) and if answer will 0 then we can say that x-3 is a factor. p(x) = x*x*x + 7x*x - 3x - 6 p(3) = 3*3*3 + 7*3*3 - 3*3 - 6 = 27 + 42 - 9 - 6 = 54 not equal to 0 so x-3 is not a factor of p(x) so g(x) is not a factor of p(x)
