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)

How are the steps for graphing a line
using slope-intercept similar to using
point-slope? How are they different?
Answer:
they both use y^2-y^1 and x^2 - x^1, one is to find the slope the other is to find the y intercept
Step-by-step explanation:
Slope-intercept is when you have a graph and a equation such as y=mx+b
y = y coordinate
m = slope
x = x coordinate
b = y intercept
point-Slope is when you have this equation and you use (x1, y1) as the coordinates to graph.
y - y1 = m * (x - x1)

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]

What integer values satisfy both inequalities?
-3<x<2
-2 ≤ x ≤ 2
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

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.
