Quantos termos tem a sequência(4,7,10...262)

Answer»

Answer:

an = a1 + (N - 1)r

157 = 4 + (n - 1) . (7 - 4)

157 = 4 + (n - 1) . 3

157 = 4 + 3n - 3

Splitting the middle term of : 2x^2+5/3x-2

Answer»

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first TERM by the constant 6 • -6 = -36

Step-2 : Find two factors of -36 WHOSE sum equals the coefficient of the middle term, which is 5 .

-36 + 1 = -35

-18 + 2 = -16

-12 + 3 = -9

-9 + 4 = -5

-6 + 6 = 0

-4 + 9 = 5 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 9

6x2 - 4x + 9x - 6

Step-4 : Add up the first 2 terms, pulling out like factors :

2x • (3x-2)

Add up the last 2 terms, pulling out common factors :

3 • (3x-2)

Step-5 : Add up the four terms of step 4 :

(2x+3) • (3x-2)

In what time will rs. 2400 amount to rs. 2646 at 10% per annum compounded semi- annualy?can you solve with clear statements please?​

Answer»

10 % annual so 5% semi annual
5% = 1/20 we can say 20 as PRINCIPAL and 1 interest so amount 20+1 = 21

Now 2646 / 2400 = (21/20)^n
We NEED to calculate VALUE of n
So divide both by 6
441/ 400 = (21/20)^n
We can say 400 is the square of 20 so n= 2
It means we take 2 times interest so ans is 1 year

the simple interest on a certain sum computes rupees 600 in 3 years and the compound interest on the same sum at the same rate and fir 2 years computes to rupees 410 find the rate of interest​

Answer»

Answer:

Step 1:

Simple Interest, S.I. = Rs. 600

Time = 3 years

Let the rate of interest be “R” %.

We have,

S.I. =  P*R*T/100

Or, P = (600 * 100) / (R * 3)  ……. (i)

Step 2:

Compound interest, C.I. = Rs. 410

Time = 2 years

We know,  

C.I. = P [{1 + R/100}ⁿ - 1]

Since the P and R is the same for compound interest, therefore, SUBSTITUTING the VALUE of P from (i),

we get  

Or, 410 = [(600 * 100) / (R * 3)]  [{1 + (R/100)² - 1]

Or, 0.0205 R = [1² + 2R/100 + (R/100)²] - 1

Or, 0.0205 R = 0.02R + (R/100)²

Or, 0.0005 R = (R/100)²

Or, R = 0.0005 * 10000 = 5 %

Thus, the rate of interest is 5%.
