Answer:

The product of (x+3)(x-3) is x²-9

Step-by-step explanation:

Given: (x+3)(x-3)

We need to find the product of the two factor.

Using distributive property

(a+b)(c+d) = ac+ad+bc+bd

(x+3)(x-3)=x(x-3)+3(x-3)

\Rightarrow x^2-3x+3x-9

Cancel like terms

\Rightarrow x^2-9

Hence, The product of (x+3)(x-3) is x²-9

Let's run through the steps

1. x(x+3)+(x+3)-3    ----------------------------    Distribute
2. x^{2} +3x-3x-9   ---------------     Simplify
3. x^{2} -9   -------------------------     Simplify

How do I verify #15 using fundamental trig identities?
expeople1 [14]

We start with the more complicated side which is the left side, and show that, on using some trigonometric identities, we will get the term on the right side .

\frac{sin \theta + tan \theta}{1+cos \theta}

Using Quotient identity for tangent function, we will get

\frac{sin \theta+ \frac{sin \theta}{cos \theta}}{1+cos \theta}

\frac{sin \theta cos \theta + sin \theta}{cos \theta(1+cos \theta)}

Taking out sine function from the numerator

=\frac{sin \theta(1+cos \theta)}{cos \theta(1+cos \theta)}

Cancelling the common term of numerator and denominator

=\frac{sin \theta}{cos \theta} = tan \theta

Martin is interested in the effects of different kinds of instruction on videogame performance. Martin asks 30 college freshmen
777dan777 [17]

Answer:

Between - groups variance

Step-by-step explanation:

From the question we see that the college freshmen are assigned to one of the three given groups. This means that they are exposed to different experimental conditions and thus it means that the variation differs as a result of different experimental conditions between the groups.

Thus, these differences reflect between - group variance.
