Determine if 9 - 4x2 is the difference of two squares and if it is, factor it.
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)

Which table represents a linear function?
At a glance, Kendra believes that the function represented on the graph is linear.
How can Kendra determine if the function is actually linear?
She can check to see if the rate of vertical increase equals the rate of horizontal increase between each pair of points.
She can check to see if the sum of each y-value and x-value in every ordered pair is the same.
She can check to see if the quotient of each y-value and x-value in every ordered pair is the same.
She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.

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

Find the five remaining trigonometric function values
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]

29. The circumference of a circle is C centimeters. The diameter of the circle is 13
centimeters.
Which expression best represents the value of ar?
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
