By Euclid's division algorithm find 305,793

Answer»

Answer:

Since 793>305, we apply the DIVISION lemma to 793 and 305 to obtain:

793=305×2+183

Since REMAINDER 183

=0, we apply the division lemma to 305 and 183 to obtain:

305=183×1+122

We consider the NEW divisor 183 and new remainder 122, and apply the division lemma to obtain

183=122×1+61

Now, the new divisor is 122 and new remainder is 61, and apply the division lemma to obtain

122=61×2+0

Since the remainder is zero, the process stops.

Also, the divisor at this stage is 61,

HENCE, the HCF of 793 and 305 is 61.

Simplify 3^-5 * 10^-5 * 125/6^-5 * 5^-7 answer asap pleaase

Answer»

Answer:

The answer is (5)^-27

Step-by-step EXPLANATION:

To simplify

Step 1 = First make the powers of all the numbers positive

That is,

= (1/3)^5 X (1/10)^5 X (6/125)^5 X (1/5)^7

We KNOW that if powers are same of the numbers in the multiplication

then we multiply the base with each other by KEEPING the power common

That is,

= (1/3 X 1/10 X 6/125)^5 X (1/5)^7

After multiplying

= (1/5 X 1/125)^5 X (1/5)^7

= (1/625)^5 X (1/5)^7

Step 2 = Make the base same, so that we can add the powers[according to the rule]

First of all make powers negative again, so that we can easily simplify

That is,

= (625)^-5 X (5)^-7

Then,

we know that 625 = (5)^4

So,

= [(5)^4]^-5 X (5)^-7

= (5)^4 X -5(POWERS GOT MULTIPLIED)] X (5)^-7

= (5)^-20 X (5)^-7

We know that when the bases are same of the numbers in multiplication we add the powers

That is,

= (5)^-20 +[-7]

= (5)^-27

3. Solve the IVP using the Laplace transform y' - 2y =4, given that y(0) = 1 *​

Answer»

Given: y' - 2y = 4,

           y(0) = 1 (this is initial value)

To find: y(t)

solution:

IVP means initial value Problem

step 1: take Laplace transform for given EQUATION:

           (sY(s) - y(0)) -2Y(s) = 4................................equation -1

     as,  y(0) = 1 (given)

so, put y(0) = 1 in equation -1, we GET

           (sY(s) - 1) -2Y(s) = 4

           sY(s) -1- 2Y(s) = 4

            Y(s) (s - 2) - 1 = 4

            Y(s) (s - 2) = 4+1

            Y(s) (s - 2) = 5

            Y(s) = \frac{5}{(s-2)}....................................................................equation -2

step 2: take Laplace inverse of equation -2, we get;

             y(t) = 5 e^{2t}

so the final ANSWER is y(t) = 5 e^{2t}

Which transversals can be drawn for two parallel line ...?​

Answer»

In geometry, a transversal is a LINE that passes through TWO lines in the same plane at two distinct points. Transversals play a role in establishing whether two other lines in the Euclidean plane are parallel. The intersections of a transversal with two lines create VARIOUS types of pairs of angles: consecutive INTERIOR angles, corresponding angles, and alternate angles. As a consequence of Euclid's parallel POSTULATE, if the two lines are parallel, consecutive interior angles are supplementary, corresponding angles are equal, and alternate angles are equal....✌✨

Find the roots of the quadratic equation x²-2x+1=0​

Answer»

Answer:

Equal roots = 1

Step-by-step explanation:

GIVEN a QUADRATIC equation such that,

{x}^{2}  - 2x + 1 = 0

To find the roots.

We need to first factorise it.

We will USE the middle term splitting method.

Therefore, we will GET,

=  >  {x}^{2}  - x - x + 1 = 0

Taking out common TERMS, we have,

=  > x(x - 1) - 1 (x - 1) = 0 \\  \\  =  > (x - 1)(x - 1) = 0 \\  \\  =  >  {(x - 1)}^{2}  = 0  \\ \\  =  > x - 1 = 0 \\  \\  =  > x = 1

Clearly, it has equal and same roots.

Hence, the required root will be 1.

Show that any positive odd integer is of form of (6m+1) or (6m+3) or (6m+5) where m is some integer.​

Answer»

Step-by-step explanation:

If the no is of form n=6m+r then r can be 0 1 2 3 4 or 5

but since it's an ODD no

when n = 6m = 2(3M)= EVEN (contradiction)

when n = 6m + 2 = 2(6m+1) = even (contradiction)

when n - 6m + 4= 2(3m + 2) = even (contradiction yet again)

so the only forms it can be are 6m+1, 6m+3, 6m+5

Hope this helps!!
