If f (x) = x square + 2 and g(x)= 5x-8 then f+g(1)=

Answer»

SOLUTION:-

Algebra of FUNCTION

f(x) = x² + 2

g(x) = 5x - 8

Then

(f + g)(x) = f(x) + g(x)

•°• (f + g) (x) = x² + 2 + 5x - 8

•°• (f + g) (1) = (1)² + 2 + 5(1) - 8

= 1 + 2 + 5 - 8

= 8 - 8

= 0

Answer.

=> (f + g) (1) = 0

The length of a rectangle is greater than twice it's breadth by 1cm if it's breadth is doubled and length is decreased by 4 cm it's area remains the same find the dimensions

Answer»

ANSWER:

l=8

b=3.5

Step-by-step explanation:

let length of rectangle be l

and breadth be b

according to question:

l=2b+1

and if...

breadth is doubled i.e. breadth = 2b

and length = l-4

then area remains same

(l×b)= (l×b)

(2b+1)×b = (2b+1-4)(2b)

2b^2+b = 4b^2-6b

2b^2=7b

b^2=3.5b

b^2/b=3.5

b = 3.5

l= 2b+1

l= 2×3.5 + 1

l= 8

2^(1+1/2+1/4+1/8+........)

Answer»

Answer:

2^(1+1/2+1/4+1/8+1/10+1/..........)

GIVEN that

given base is 2

and the exponent is

(1+1/2+1/4+1/8+1/10+1/....)

then you addexponent

in above given

then

2^(1+1/2+1/4+1/8+1/10+1/...)

or

you can write in exponent that

(1+1/2+1/4+1/6+1/8+1/10+1/.......)

you can write in exponent that (/6+1/)

as your wish

then

Step-by-step explanation:

2^(1+1/2+1/4+1/8+1/10+1/...)

2^(2/3/5/9/11..)

2^(0)

=2

because you written in divison

like (1+1/2+1/...) you written in by

then

divison is 0(zero)

then answer is 2

exponent will 0( zero )

REMAINING is base

then base is 2

then answer is

2

hence proved
