Answer» ong>ANSWER: TIME = 5 years Step-by-step explanation: P = 6400 A = 9280 I = Amount - P = 9280 - 6400 = 2880 R = 9% ∵ I = ( P × T × R)/100 ⇒ T = ( I × 100 ) / ( P × R ) = ( 2880 × 100 )/( 6400 × 9) = 5

8.

A sum of 6,400, accumulated to 9,280, in a certain period. If the rate of simple interest is 9%, find the period.

Answer»

ong>ANSWER:

TIME = 5 years

Step-by-step explanation:

P = 6400

A = 9280

I = Amount - P = 9280 - 6400 = 2880

R = 9%

∵ I = ( P × T × R)/100

⇒ T = ( I × 100 ) / ( P × R ) = ( 2880 × 100 )/( 6400 × 9) = 5

An alternative way of solving problems. Use discriminant to find the minimum value of . Thank you for solving my problems! Hint: touches each other for certain value of k, and 'touching' means have at least one solution.

Answer»

ong>Answer:

y=f(x) is a parabola

y=ky=k is a HORIZONTAL line

If two intersects, that will be the solution of the system EQUATION of

\begin{gathered}\begin{cases} & y=k \\ & y=f(x) \end{cases}\end{gathered}

{

y=k

y=f(x)

So LET's SOLVE the system equation.

f(x)=kf(x)=k

\longleftrightarrow 2x^2-7x+2=k⟷2x

2

−7x+2=k

\longleftrightarrow 2x^2-7x-k+2=0⟷2x

2

−7x−k+2=0

\boxed{D=33+8k\geq 0}

D=33+8k≥0

Thus, y=ky=k intersects if and only if k\geq -\dfrac{33}{8}k≥−

. So, the lowest location of the horizontal line is y=-\dfrac{33}{8}y=−

15.

Find the H.C.F of the following polynomials:2a²x-a² and 4ax²-a

Answer»

ong>Step-by-step explanation:

First expression = X2 - 3x - 18

= x2 - 6x + 3x - 18, by SPLITTING the MIDDLE term - 3x = - 6x + 3x

= X(x - 6) + 3(x - 6)

= (x - 6) (x + 3)

Second expression = x2 + 5x + 6

= x2 + 3x + 2x + 6, by splitting the middle term 5x = 3x + 2x

= x(x + 3) + 2(x + 3)

= (x + 3) (x + 2)

16.	A takes 8 days more than'b' to complete a certain work.If both of them together can complete 90% of the work in 16 days.then find the time taken by 'B' to complete the whole work alone??
Answer» ong>Answer: Let the time taken by B working alone = X days, So, time taken by A working alone = (x + 8) days ∵ A complete 75% of the work, So, the day he will work = 75% of (x+8) = 75(x+8)/100=3(x+8)/4 B has to complete 25% of work, That is, days he will work = 25% of x = x/4 Since, B leaves the work 9 days before the work is finished, Days for which A worked - Days for which B worked = 9 days. 3 (x+8)/4 - x/4 = 9 (2X + 24) / 4 = 9 2x = 24 X = 6 Now, x + 8 = 6 + 8 = 14 Hence, time taken by A to finish the work alone would be 14 days.

16.

A takes 8 days more than'b' to complete a certain work.If both of them together can complete 90% of the work in 16 days.then find the time taken by 'B' to complete the whole work alone??

Answer»

ong>Answer:

Let the time taken by B working alone = X days,

So, time taken by A working alone = (x + 8) days

∵ A complete 75% of the work,

So, the day he will work = 75% of (x+8) = 75(x+8)/100=3(x+8)/4

B has to complete 25% of work,

That is, days he will work = 25% of x = x/4

Since, B leaves the work 9 days before the work is finished,

Days for which A worked - Days for which B worked = 9 days.

3 (x+8)/4 - x/4 = 9

(2X + 24) / 4 = 9

2x = 24

X = 6

Now, x + 8 = 6 + 8 = 14

Hence, time taken by A to finish the work alone would be 14 days.

3) Solve the follow following Suhquestionscy If 2x + 3y = 10 and 3x+24: 15, findthe value of (x+y)

Answer»

ong>Step-by-step explanation:

2x+3y =10 ( leave it there for now)

3x + 24 = 15

3x =15-24

3x =- 9

x = -9/3

x= -3

2x+ 3 y = 10

2*-3+3y =10

-6+3y=10

3y=10+6

3y=16

y=5.33

∆ (x+y)
