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:

9 units

Step-by-step explanation:

The dotted line, which is the height, is labeled as 9, so it is 9 units.

Hope that helps!

Answer: 9 units

Step-by-step explanation: If you look at the question on the photo you see a dotted line with a 9 on it. On a triangle when you something like that you know it the actual height of the triangle

Step-by-step explanation: you plug in -1 as x for g(x) and you use the answer from that (which is 6) and plug that into f(x)

The value of composite function (fog)(-1) = 10/3.

A function whose values are obtained from two given functions by first applying one to an independent variable and then using the result to apply the second, and whose domain is made up of those independent variable values for which the first function's result falls within the second function's domain.

The two functions are given below:

f(x) = 8/x+2

g(x) = 4x² + 2

To evaluate the composite value  (fog)(-1), first solve for g(-1).

Put x = -1 in 'g' function

g(x) = 4x² + 2

g(x) = 4(-1)² + 2

      = 4 + 2

g(x)  = 6

Now, substitute the value of g(6) in 'f' function

f(x) = 8/x+2

f(6) = 8/6 + 2

     = 10/6

Therefore, the composite value (fog)(-1) = 10/3.

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:

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:

- 2, - 1, 0, 1

Step-by-step explanation:

Consider the integers that satisfy each inequality

- 3 < x < 2

solutions are x = - 2, - 1, 0, 1

- 2 ≤ x ≤ 2

solutions are x = - 2, - 1, 0, 1, 2

Thus the integer values that satisfy both are common to both, that is

x = - 2, - 1, 0, 1

Answer:

5x + 5

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

f(x) + g(x)

= 2x + 3 + 3x + 2 ← collect like terms

= 5x + 5

Answer:

Step-by-step explanation:

(f+g)(x)=f(x)+g(x)

(f+g)(x)=2x+3+3x+2
