Answer:

Solving $6(2 - x)$ we get $\mathbf{x>5}$

Step-by-step explanation:

We need to find solution of $6(2 - x)$

Solving the inequality:

$6(2 - x)$

Multiply 6 with terms inside the bracket

$12-6x$

Subtracting 12 on both sides

$12-6x-12$

Adding 4x on both sides

$-6x+4x$

Divide both sides by -2 and the inequality will be reversed i.e < will be changes to >

$\frac{-2x}{-2}>\frac{-10}{-2}\\\mathbf{x>5}$

So, after solving $6(2 - x)$ we get $\mathbf{x>5}$

Answer:

x=pi*n/2+1/2arctan(7/5)

Step-by-step explanation:

5sin(2x)=7cos(2x)

5tan(2x)=7/5

2x=pi*n+arctan(7/5)

x=pi*n/2+1/2arctan(7/5) for n e Z

WILL GIVE BRAINLIST. PLEASE HELP.

Answer:

$0$

Step-by-step explanation:

Please refer to the image attached with this answer. Assuming our triangle to be ΔABC and Line AD meeting BC at D.

As we are given that side b = side c

The angle subtended by them ∠B and ∠C must be equal . Let us assume them to be x each . hence

x + x + 52° +31° = 180°

2x + 73° = 180°

2x = 180°- 73°

2x = 107 °

x = 53.5°

Hence in ΔACD

x+ 31°+∠2= 180°

53.5°+31°+ ∠2 = 180°

∠2=180°-84.5°

∠2=95.5°

Also

∠1 + ∠2 = 180°

∠1 + 95.5° = 180°

∠1 = 180°-95.5°

∠1 =84.5°

Now applying Sine rule in ΔABD

$\frac{\sin 52}{12}=\frac{\sin 84.5}{c}$

$\frac{0.7886}{12}=\frac{0.9953}{c}$

$c=\frac{0.9953 \times 12}{0.7886}$

$c=15.14$

Hence we have c as 15.14

as we are given that side c = side b , b=15.14

The properties of any triangle says that the sum of two sides of any triangle is always greater than the third side. Hence

a<b+c

12+2x-6<15.14+15.14

6+2x<30.28

2x<30.28-6

2x<24.28

x<12.14

also side a must be greater than 0

12+2x-6>0

6+2x>0

2x>-6

x>-3

Hence the range of x will be

-3 <x < 12.14

Let a=(?2,1,2, b=(?1,2,4, and p=(k,k,k. the vector from a to b is perpendicular to the vector from a to p when k =

prohojiy [21]

Vector a = (2, 1, 2)
Vector b = (1, 2, 4)
Vector p = (k, k, k)

Vector a to vector b = vector b - vector a = (1, 2, 4) - (2, 1, 2) = (1 - 2, 2 - 1, 4 - 2) = (-1, 1, 2)
Vector a to vector p = vector p - vector a = (k, k, k) - (2, 1, 2) = (k - 2, k - 1, k - 2)

Vector a to b is perpendicular to vector a to p if the dot product of vector a to vector b and vector a to vector p is equal to zero.
i.e. (-1, 1, 2) . (k - 2, k - 1, k - 2) = 0
-1(k - 2) + (k - 1) + 2(k - 2) = 0
-k + 2 + k - 1 + 2k - 4 = 0
2k -3 = 0
2k = 3
k = 3/2
