Alissa is analyzing an exponential growth function that has been reflected across the y-axis. She states that the domain of the reflected function will change because the input values will be the opposite sign from the reflected function. Simon disagrees with Alissa. He states that if an exponential function is reflected across the y-axis, the domain will still be all real numbers.

What's the product of these binomials (x-9) (x+2)

Answers

Answer:

$(x-9)*(x+2)=x^2 - 7x -18$

Step-by-step explanation:

Let's find the solution, but first we need to understand the following:

multiplication of binomials establish that:

$(a-b)*(c+d)=(a*c) + (a*d) + ((-b)*(c)) + ((-b)*(d))$

now, because your binomials are (x-9) and (x+2), using the above we obtain:

$(x-9)*(x+2)=(x*x) + (x*2) + ((-9)*x) + ((-9)*2)$

which can be simplified as:

$(x-9)*(x+2)=x^2 + 2x - 9x -18$

giving the solution:

$(x-9)*(x+2)=x^2 - 7x -18$

Answer:

$x^(2)$ -7x-18

Review the incomplete derivation of the cosine sum identity.A 2-column table with 5 rows. Column 1 has entries step 1, step 2, step 3, step 4, step 5. Column 2 has entries cosine (x + y), sine (StartFraction pi Over 2 EndFraction minus (x + y) ), blank, sine (StartFraction pi Over 2 EndFraction minus x) cosine (negative y) + cosine (StartFraction pi Over 2 EndFraction minus x) sine (negative y), blank.

Which expressions for Step 3 and Step 5 complete the derivation?

Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) + y )
Step 5: cos(x)cos(y) + sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) + y )
Step 5: cos(x)cos(y) – sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) minus y )
Step 5: cos(x)cos(y) + sin(x)sin(y)
Step 3: Sine ( (StartFraction pi over 2 EndFraction minus x) minus y )
Step 5: cos(x)cos(y) – sin(x)sin(y)
