Which expression represents the growth of an investment of $1,500 at 12% per year for a period of t years?A. 1500(12)tB. 1500(0.12)tC. 1500t1.12D. 1500(1.12)t

Answer»

Given:

An investment of $1,500 at 12% per year for a period of t years

To find:

The expression representing the GROWTH of an investment

Solution:

We know the formula for calculating the future value of an investment is as follows:

\boxed{\bold{FV = PV[1 + i]^<klux>N</klux>}}

where

FV = future value of an investment

PV = Present value

i = rate of interest

n = no. of years

Here we have

PV = $ 1500

i = 12%

n = t years

Therefore, on substituting the values in the formula, we get

FV = 1500 [1 + \frac{12}{100} ]^t

\implies FV = 1500 [1 + 0.12 ]^t

\implies \bold{FV = 1500 [1.12 ]^t}option (D)

Thus, the expression that represents the growth of an investment of $1,500 at 12% per year for a period of t years is → \boxed{\bold{1500 [1.12 ]^t}}.

24. Father's age is three times the sum of ages of his two children. After 5 years his age will betwice the sum of ages of two children. Find the age of father.PLZ ANSWER THE QUESTIONS, IF I GET HELP FROM THIS I DEFINITELY MARK AS BRAINLIEST...​

Answer»

Step-by-step explanation:

LET,

the age of father is x and two sons age is y .

After 5 years

father age = (x + 5)

sum of the age of his children = ( y+ 10)

from the GIVEN information, we have

x = 3y ..... (1)

and then x+5 = 2(y+10)

x - 2y = 15........(2)

from the (1) and (2)

3y - 2y =15 = y= 15

x = 3y

therefore, x = 45

father age is 45.

Umy question is 7m^4n-7mn^4​

Answer»

Given: The term 7m^4n - 7mn^4

To FIND: FACTORISE the given term.

Solution:

  • Now the given term is 7(m^4)n - 7m(n^4)
  • Taking COMMON terms out, we get:

                 7mn(m³ - n³)

  • Now we know the formula:

                 a³ - b³ = (a - B)(a² + AB + b²)

  • Applying this, we get:

                 7mn(m - n)(m² + mn + n²)

Answer:

            So the factors are 7mn(m - n)(m² + mn + n²)

Answer»

Step-by-step explanation:

⚫ Given :- a = 2 + √3

⚫ To FIND :- a³ + 1/a³ = ?

⚫ Solution :- a = 2 + √3

\frac{1}{a} = \frac{1}{2 + \sqrt{3} } \\ \\ \frac{1}{a} = \frac{1}{2 + \sqrt{3} } \times \frac{2 - \sqrt{3} }{2 - \sqrt{3} } \\ \\ \frac{1}{a} = \frac{2 - \sqrt{3} }{4 - 3} \\ \\ \frac{1}{a} = 2 - \sqrt{3} \\ \\ a + \frac{1}{a} = 2 + \sqrt{3} + 2 - \sqrt{3} \\ \\ a + \frac{1}{a} = 4 \\ \\ take \: \: CUBE \: \: both \: \: side \: \: \\ \\ {(a + \frac{1}{a} )}^{3} = {4}^{3} \\ \\ {a}^{3} + \frac{1}{ {a}^{3} } + 3a \times \frac{1}{a} (a + \frac{1}{a} ) = 64 \\ \\ {a}^{3} + \frac{1}{ {a}^{3} } + 3(4) = 64 \\ \\ {a}^{3} + \frac{1}{ {a}^{3} } = 64 - 12 \\ \\ {a}^{3} + \frac{1}{ {a}^{3} } = 52

a number consists of two digit when it is divided by the sum of the digits, the quotient is 6 and remainder is 3.If the digits are interchanged the quotient is 4 and remainder is 9​

Answer»

Answer:

75

Step-by-step explanation:

LET the two digit NUMBER be 10x+y and no. obtained by interchanging the digital = 10y+x

As per the first condition

10x+y= 6 (x+y)+3

4x-5y=3.. (i)

As per the second condition

10y+x=4 (x+y)+9

-3x+6y=9.... (ii)

Multiplying equation (i) by 3 and (ii) by 4 and ADDING them, we get

12x-15y=9

-12x+24y=36

___________

9y=45

y=455

Substitute y=5 in equation (i)

4x- 5X5=36

4x=28

x=7

So the numbers are 10x+y=10×7+5=75

HOPE THIS HELPS YOU!!

HAVE A NICE DAY!!
