4.	Answer me fast please...no wrong answers please..
Answer» Solution..... F (x) = x ^2 f(1) = 1^2 = 1. and f (1.1) = (1.1)^2 = 1.21 [ f (1.1) - f (1) ] ÷ [1.1 -1] = [ 1.21 - 1 ] ÷ 0.1 = 0.21 ÷ 0.1 = 2.1 is the ANSWER of your questions.

4.

Answer me fast please...no wrong answers please..

Answer»

Solution.....

F (x) = x ^2

f(1) = 1^2 = 1.

and

f (1.1) = (1.1)^2 = 1.21

[ f (1.1) - f (1) ] ÷ [1.1 -1]

= [ 1.21 - 1 ] ÷ 0.1

= 0.21 ÷ 0.1

= 2.1 is the ANSWER of your questions.

10.	The sum of three consecutive multiple of 8 is 888 .find multiple
Answer» Answer: Step-by-step EXPLANATION: → Let the first MULTIPLE of 8 be 8x. → Therefore the second consecutive multiple of 8 will be 8(x+1) → ALSO the third consecutive multiple of 8 will be 8(x+2). → It is given that the sum of these three consecutive MULTIPLES of 8 is 888 = 8x + 8(x+1) + 8(x+2) = 888 = 8x + 8x + 8 + 8x + 16 = 888 = 24x + 24 = 888 → Take 24 on the RHS = 24x = 888 - 24 = x = 864/24 = x = 36. → Therefore First multiple of 8 be 8x = 8 x 36 = 288 → Second Multiple of 8 be 8(x + 1) = 8(36 + 1) = 8 x 37 = 296 → Third Multiple of 8 be 8(x + 2) = 8(36 + 2) = 8 x 38 = 304 → If we sum up these three multiples i.e (288 + 296 + 304) we get 888.

10.

The sum of three consecutive multiple of 8 is 888 .find multiple

Answer»

Answer:

Step-by-step EXPLANATION:

→ Let the first MULTIPLE of 8 be 8x.

→ Therefore the second consecutive multiple of 8 will be 8(x+1)

→ ALSO the third consecutive multiple of 8 will be 8(x+2).

→ It is given that the sum of these three consecutive MULTIPLES of 8 is 888

= 8x + 8(x+1) + 8(x+2) = 888

= 8x + 8x + 8 + 8x + 16 = 888

= 24x + 24 = 888

→ Take 24 on the RHS

= 24x = 888 - 24

= x = 864/24

= x = 36.

→ Therefore First multiple of 8 be 8x = 8 x 36 = 288

→ Second Multiple of 8 be 8(x + 1) = 8(36 + 1) = 8 x 37 = 296

→ Third Multiple of 8 be 8(x + 2) = 8(36 + 2) = 8 x 38 = 304

→ If we sum up these three multiples i.e (288 + 296 + 304) we get 888.

15.

Find the valus of k2x2 + kx + 3 = 0

Answer»

QUESTION:

Find the values of k so that the POLYNOMIAL has two EQUAL roots.

$2x^{2} + kx + <klux>3</klux> = 0$

Solution:

In the given polynomial,

a = 2

b = k

c = 3

Roots are equal here,

$\boxed{ D = b^{2} - 4ac = 0}$

$b^{2} - 4ac = 0 \\ k^{2} - 4(2)(3) = 0 \\ k^{2} = 24 \\ k = \pm\sqrt{24}$

Therefore, the values of k are $-\sqrt{24}$ and $+\sqrt{24}$
