Answer:

D

Step-by-step explanation:

i = √-1 , as number inside a √ cannot be a negative number, i is an imaginary number

2 + √-36

= 2 + √(36×-1)

= 2 + 6i, d

Answer:

Step-by-step explanation:

the simpliest form is [tex]1\frac{2}{5}[/tex]

It already is a fraction. If you need it simplified, it would be 1 2/5.

15 is the answer

Step-by-step explanation: 9.0 divided by 0.6 = 15. Hope this help!!!

Answer:

Step-by-step explanation:

9 = 3 * 3 = 3²

4x² = 2²x² = (2x)²

9 - 4x² = 3² - (2x)²     {a² - b² = (a + b)(a - b) ; a = 3 ; b = 2x}

          = (3 +2x)(3 - 2x)

Answer:

Sin O = [tex]\frac{2\sqrt{5} }{5}[/tex]

Cos O = [tex]-\frac{\sqrt{5} }{5}[/tex]

Cot O =  [tex]-\frac{1}{2}[/tex]

Csc O =  [tex]\frac{\sqrt{5} }{2}[/tex]

Sec O = [tex]-\sqrt{5}[/tex]

Step-by-step explanation:

Do you know the definitions of all the trig functions?  If not, you need to memorize them.  Also, you need to memorize which functions are positive in each quadrant.  All functions are positive in quad I, sine and reciprocal are positive in quad II, tan and reciprocal are positive in quad III, and cos and reciprocal are positive in quad IV.  OK?

Tan of  an angle is opposite side/adjacent side of a right triangle

If the tan O = - 2. let the opp. side = 2 and adjacent side = 1.  Then the hypotenuse = [tex]\sqrt{2^{2} + 1^{2} } = \sqrt{4 + 1} = \sqrt{5}[/tex]

Sine is positve and equals opp/hyp = [tex]\frac{2}{\sqrt{5} } = \frac{2\sqrt{5} }{5}[/tex]

Cos is negative and equals adj/hyp  =  [tex]-\frac{1}{\sqrt{5} } = -\frac{\sqrt{5} }{5}[/tex]

Cot is negative and is the reciprocal of the tan or adj/opp = [tex]\frac{-1}{2}[/tex]

Csc is positive and is the reciprocal of the sine or hyp/opp = [tex]\frac{\sqrt{5} }{2}[/tex]

Sec is negative and is the reciprocal of the cos or hyp/adj = [tex]-\sqrt{5}[/tex]

Answer:

x²+6x+9=0

x²+3x+3x+9=0

x(x+3)+3(x+3)=0

(x+3)(x+3)=0

either

x+3=0

x=-3

or

x+3=0

x=-3

Step-by-step explanation:

next method

x²+6x+9=0

x²+2×x×3+3²=0

it is in formula of (x+y)²

(x+3)²=0

x+3=√0

x+3=0

x=-3

Answer:If the diameter is 13 you should try each answer until you find pi.

To find pi you have to divide the circumference by the radius.

You don't need to find the circumference in this question but you can.

The circumference is 40.82

Then you have to divide

40.82÷13

that equals 3.14

and because that is pi, C is your answer

Answer:

x < 6

Step-by-step explanation:

18 > 12 + x

Switch sides:

12 + x < 18

Subtract 12 from both sides:

12 + x - 12 < 18 - 12

x < 6

The solution of the inequality is,

⇒ x < 6

And, Graph is shown in image.

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequality is,

⇒ 18 > 12 + x

Now, We can solve the inequality as;

⇒ 18 > 12 + x

Switch sides:

⇒ 12 + x < 18

Subtract 12 from both sides:

⇒ 12 + x - 12 < 18 - 12

⇒ x < 6

Thus, The solution of the inequality is,

⇒ x < 6
