Answer:

The exact value of cos(-60\°)=(1/2)

Step-by-step explanation:

we know that

The angle -60\° belong to the fourth quadrant

The function cosine is positive in the first and in the fourth quadrant

so

cos(-60\°)=cos(60\°)

Remember that

cos(60\°)=(1/2)

so

cos(-60\°)=(1/2)

<h2><em><u>HEYA</u></em></h2>

<h3>THE MID TERM SPLITTING OF THE EQUATION IS :</h3>

{x}^{2}  + 3x - 4

{x}^{2}  + 4x - x - 4

x(x + 4) - 1(x + 4)

x =  -4 \: and \: 1

x = 1

now shifted to 5 units left

therefore,

x=-4

Use the quadratic formula to find the complex solutions to the equation 10x2 – x + 9 = 0.
melomori [17]

Quadratic formula: (-b +/- sqrt(b^2 - 4ac)) / 2a

a = 10

b = -1

c = 9

1 +/- sqrt((-1)^2 - 4(10)(9)) / 2(10)

1 +/- sqrt(1 - 360) / 20

x = 1 +/- sqrt(359i) / 20

Hope this helps!

What is the m∠ACB in the circle shown below?
GuDViN [60]

Question:

What is the m∠ACB in the circle shown below?

Answer:

45

Step-by-step explanation:

So we know it is <u><em>less than a right angle</em></u> and it is not a obtuse angle it is less than 90 degrees. 45 is less, 90 is equal(<em>not what we are looking for</em>) , 120, is greater, and 180 is greater which leaves us to our answer 45.

Alex17521 [72]

[ Answer ]

\boxed{X \ = \ 114}

[ Explanation ]

\frac{x}{19} = 6

Multiply Both Sides By 19

\frac{x}{19} = 6 · 19

Simplify:

X = 114

Check Your Work:

\frac{114}{19}

Simplify:

= 6
