The answer is A.80.3
equation to use is C=cos^-1 [a^2+B^2+-2^2 /2ab
A=21
B=33
C=36
21^2+33^2-36^2
21^2=441
33^2=1089
36^2=1296
441+1089=1530
1530-1296=234
234/2=117
cos^-1*117=80.28
rounded gives you 80.3, hope this helps :D
doing the math i got 82.3 but please check  in with someone else

If g(x) is the inverse of f(x)=4x+12 and f(x)=, what is g(x)

Answers

Answer:

f^(-1)(x)=g(x)=(x-12)/(4)

Step-by-step explanation:

The problem tell us that g(x) is the inverse of f(x), where:

f(x)=4x+12

So, we need to find the inverse function of f(x) in order to find g(x)

Let's find the inverse function using the following steps:

1. Replace  f(x) with y:

f(x)=y=4x+12

2. Solve the equation for x:

(y-12)/(4) =x

3. Replace every x with a y and replace every y with a x:

y=(x-12)/(4)

4. Finally, replace y with f^(-1)(x)

f^(-1)(x)=(x-12)/(4)

Therefore:

g(x)=f^(-1)(x)=(x-12)/(4)

Hello,
f(x)=y=4x+12

x=4y+12
==>4y=x-12
==>y=x/12- 3

g(x)=x/12 -3

What is the difference of the polynomials?(5x3 + 4x2) – (6x2 – 2x – 9)

A. –x3 + 6x2 + 9
B. –x3 + 2x2 – 9
C. 5x3 – 2x2 – 2x – 9
D. 5x3 – 2x2 + 2x + 9

Answers

(5x³ + 4x²) - (6x² - 2x - 9)

-1(6x²) -1(-2x) -1(-9) = -6x² + 2x + 9

5x³ + 4x² - 6x² + 2x + 9

5x³ - 2x² + 2x + 9  Choice D.


The difference between the polynomials (5x³-4x²)-(6x²-2x-9) is 5x³-2x²+2x+9 and the right option is D. 5x³-2x²+2x+9.

What is polynomial?

A polynomial is an expression of more than two algebraic terms

To calculate the difference between both polynomials we apply the techniques below.

Given:

  • (5x³-4x²)-(6x²-2x-9)

Substrat each like term accordingly.

  • (5x³-0)+(4x²-6x²)+(0-2x)+(0-9)
  • 5x³-2x²+2x+9

Hence, the difference between the polynomials (5x³-4x²)-(6x²-2x-9) is 5x³-2x²+2x+9 and the right option is D. 5x³-2x²+2x+9.
