Answer»

Step-by-step EXPLANATION:

x+2x-2x+x-1=2x-1

the REMAINDER must be 0 when divisible by x+x-2=2x-2

4.	What is the value oftan45/2 =?
Answer» Step-by-step explanation: 22½° lies in the first quadrant. Hence it is positive.. tan (2 x 22.5)= [2TAN (22.5)]/[1 - tan²22.5] tan 45 [1 - tan²22.5] = 2tan 22.5 1 - tan²22.5 = 2tan 22.5 Let x = tan 22.5 1 - x² = 2X x² + 2x - 1 = 0 x = [- 2 ± √(8)]/2 x = - 1 ± √(2) but it is in the first quadrant so.. its value MUST be positive tan 22.5 = - 1 + √(2).. Hope it HELPS.. Please MARK it brainliest...

4.

What is the value oftan45/2 =?

Answer»

Step-by-step explanation:

22½° lies in the first quadrant.

Hence it is positive..

tan (2 x 22.5)=

[2TAN (22.5)]/[1 - tan²22.5]

tan 45 [1 - tan²22.5] =

2tan 22.5

1 - tan²22.5 = 2tan 22.5

Let x = tan 22.5

1 - x² = 2X

x² + 2x - 1 = 0

x = [- 2 ± √(8)]/2

x = - 1 ± √(2)

but it is in the first quadrant so.. its value MUST be positive

tan 22.5 = - 1 + √(2)..

Hope it HELPS..

To FIND : The value of P(F) ? Solution : We know that maximum probability for occurrence of any event is 1. So, P(E) + P(F) = 1 We have given, P(E) = 0.72 Substitute the value, $0.72 + P(F) = 1$ $P(F) = 1 - 0.72$ $P(F) = 0.28$ Therefore, The probability of F is $P(F) = 0.28$ . #Learn more If e and f are events such that p(E) = 0.25 , p(F) = 0.50 and P( E and F ) = 0.125, find P ( not E and not F) . brainly.in/question/15191566

Answer»

The probability of F is $<klux>P</klux>(F) = 0.28$ .

Step-by-step EXPLANATION:

Given : In an experiment, E and F are the only two POSSIBLE OUTCOMES. If P(E) = 0.72.

To FIND : The value of P(F) ?

Solution :

We know that maximum probability for occurrence of any event is 1.

So, P(E) + P(F) = 1

We have given, P(E) = 0.72

Substitute the value,

$0.72 + P(F) = 1$

$P(F) = 1 - 0.72$

$P(F) = 0.28$

Therefore, The probability of F is $P(F) = 0.28$ .

If e and f are events such that p(E) = 0.25 , p(F) = 0.50 and P( E and F ) = 0.125, find P ( not E and not F) .

Answer»

Answer:

Step-by-step explanation:

LET the fraction be x/y

1 is ADDED means

x+1/y+1=4/5

5x+5=4y+4

5x-4y=-1

5 is SUBTRACTED means

x-5/y-5=1/2

2x-y=5

2 EQN multilply by 5 and 1 eqn by 2

2(5x-4y=-1)=10x-8y=-2

5(2x-y=5)=10x-5y=25

10x-5y=25

10x-8y=-2

x=7,y=9

16.

In triangle ABC right angled at B . AB=5cm and angle ACB =30` determinethe lengths of the sides BC and AC.

Answer»

ANSWER:

BC = 5√3cm

AC = 10cm

Given:

∠ABC = 90°

∠ACB = 30°

AB = 5cm

To FIND:

BC and AC

Solution:

FINDING AC

$\sf sin30 ^\circ = \dfrac{AB}{AC}$

$\sf \dfrac{1}{2} = \dfrac{5}{AC}$

AC = 10cm

Finding BC

$\sf cos30^ \circ = \dfrac{BC}{AC}$

$\sf\dfrac{\sqrt{3}}{2} = \dfrac{BC}{10}$

2BC = 10√3

$\sf BC = \dfrac{10\sqrt{3}}{2}$

BC = 5√3

21.

If x + y = 2xy & x – y = 6xy Find ‘x + 2y’.

Answer»

Step-by-step EXPLANATION:

X+y=2xy.............(1)

x-y=6xy........(2)

Divide eq(1) & (2) by XY on both sides

x/xy + y/xy = 2xy/xy

1/y +1/x = 2...............(3)

x/xy - y/xy = 6xy/xy

1/y - 1/x = 6....................(4)

Adding eq (3) & (4)

1/y +1/y = 6+2

2/y = 8

8y = 2

y= 2/8 = 1/4

y= 1/4

Put this value of y in eq (3)

1/y +1/x = 2

4+ 1/x = 2

1/x = 2-4

1/x =-2

x= -1/2

X + 2y

= -1/2 + 2×1/4

= -1/2 + 1/2

= 0 (Ans)
