\bigstar CORRECT QUESTION :

\star \bold{a^x=b^y=c^z,b^2=ac} . Then SHOW that  \bf{\frac{1}{x}+\frac{1}{z}=\frac{2}{y}}

\bigstar Solution :

\star Let ,

\bf{Let,\;a^x=b^y=c^z=k}\\\\ \implies\bf{a=k^{1/x},b=k^{1/y},c=k^{1/z}}

\star Now SUB. these in b²=ac , we get ,

\implies \bf{(k^{1/y})^2=k^{1/x}.k^{1/z}}\\\\\implies \bf{k^{2/y}=k^{1/x + 1/y}}

\star BASES are equal.So exponents must be equal.

\implies\bf{\frac{2}{y}=\frac{1}{x}+\frac{1}{z}}

Hence Proved

Find A and B if :A B+3 7_____6 A​

Answer»

Answer:

As a:b=4:7, a=4x and b=7x. Now b:c=5:6, so b/c=5/6 which implies that c=6b/5. So c=(6X7x)/5 = 42x/5. a:b:c = 4x:7x:42x/5. On multiplying by 5 to simplify the ratio, we GET. a:b:c = 20:35:42.

Show that for any natural number n, the digit in units place of 3^n cannot be even​

Answer»

Step-by-step explanation:

USE induction on the exponent: The last digit is EITHER 1, 3, 7 or 9. If 1 or 3, multiplying a power of 3 will not change the EVENNESS of the second last digit. If 7 or 9, multiplying will RESULT in a carry over of 2, which again does not change the evenness of the second last digit.

A quadratic polynomial which have no zeroes

Answer»

A quadratic polynomial which have no ZEROES

Answer :

Eg : x² + 4x + 6

EXPLANATION :

Given,

f ( x )  = x² + 4x + 6

If the discriminant of the equation < 0, then the given polynomial has no zeros.

Discriminant = b²- 4AC

                     = 42 - 4(1)(6)

                     =16 - 24

                     = - 8 < 0

So the given quadratic polynomial have no zeroes.

Sketch the graph of |x|+|y|=4

Answer»

Answer:

sorry , i cant sketch it bcz my SKETCHING is not too good

Step-by-step EXPLANATION:

Explanation:

Let's put this into slope-intercept form to make graphing easier. The general equation for that form is:

y

=

m

x

+

b

where m is the slope and b is the y-intercept. So we'll get:

x

+

y

=

4

y

=

−

x

+

4

The y-intercept is 4, so that's a point  

(

0

,

4

)

.

The slope is  

−

1

, so the graph will move one point down for every point it moves right. The NEXT point we can graph is  

(

1

,

3

)

. Use a straightedge to connect those two DOTS and make the graph. It'll look like this:

graph{-x+4 [-10, 10, -5, 5]}

The sum of the three consecutive numbers is 15 and product is 80 find the numbers

Answer»

ANSWER:

The NUMBERS are 2, 5, 8

Step-by-step explanation:

Let the first term be a and common difference be d.

The THREE terms are,

a−d,a,a+d

As, the sum of three terms is 15, then,

a−d+a+a+d=15

3a=15

a=5

As, the product of three terms is 80, then,

(5−d)5(5+d)=80

5(25−d2)=80

25−d2=16

d2=9

d=±3

The numbers are 2,5,8 or 8,5,2.
