What is the value of X?
Leviafan [203]

Answer:

x=20

Step-by-step explanation:

First, find LJ

Angle L = 60 (180 - 30 - 90)

The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

cos(L)=adj/hyp

cos(60)=LJ/40√2

LJ = cos(60)*40√2

LJ = 20√2

Now you can use LJ to find x. You also know the value of each angle, 45

x=20√2⋅cos(45)

x=20

x = 2

<em>right</em><em> </em><em>option</em><em> </em><em>is</em><em> </em>(E).

Step-by-step explanation:

f(x) = x³ - 3x² + 12 in interval [-2, 4]

{taking f'(x) by doing derivative of f(x)}

f'(x) = 3x² - 6x

.•. f'(x) = 0

0 = 3x² - 6x

0 = 3x(x - 2)

0 = x - 2

x = 2

Solve the simultaneous equations:<br><br> 3a-2b=14 <br> 12a+9b=39
kirill [66]
Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1
