B. The zeroes of f (x) and 4 and -6 since f(x) =(x+4)(x-6)
C.the zeroes of f (x) are -4 and 6 since f (x)=(x-4)(x+6)
D.the zeroes of f(x) are 4 and -6 since f(x)=(x+4)(x-6)

Answers

Answer 1

Answer:

None of the given options is correct.

Step-by-step explanation:

Given:

[tex]f(x)=x^2-2x-24[/tex]

To find:

the true statement

Solution:

[tex]f(x)=x^2-2x-24[/tex]

Here,

[tex]-2=-6+4[/tex]

[tex]f(x)=x^2-6x+4x-24\\=x(x-6)+4(x-6)\\=(x+4)(x-6)[/tex]

To find the zeroes of [tex]f(x)[/tex], put [tex]f(x)=(x+4)(x-6)=0[/tex]

[tex](x+4)(x-6)=0\\x+4=0\,,\,x-6=0\\x=-4,6[/tex]

So, zeroes are [tex]-4[/tex] and [tex]6[/tex]

None of the given options is correct.

Okay so you would use the formula to find all sides which is: a2+b2=c2(pretend it’s squared, my keyboard isn’t fancy) then you would plug in the sides into the formulado it would be
5.5+x=12(everything is still squared)
After simplifying the exponent you would have:
30.25+x2=144
Now you would simplify each side
X2=4.33
And then cancel out the 2
Then you would get your answer

Find the five remaining trigonometric function values

Answers

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]

Consider functions f and g. f(x) = 8/x+2 g(x) = 4x^2 + 2 Evaluate the function composition. (f ° g)(-1)= _____

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.

What is composite function?

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.
