Answer:

42

we can use trigonometric ratios (cos, sin, tan) to solve this

cos(54)=AD/20\\20cos(54)=AD\\AD=12\\

Using the pythagorean theorum we see that BD is 16

now we can use tan to solve for DC

tan(28)=16/DC\\DC=16/tan(28)\\DC=30\\30+12=42; AC=42

Suppose f(x)=x^2. what is the graph of g(x)=f(3x)?<br>​
Katarina [22]

Answer:

D

Step-by-step explanation:

because since there is no negative sign in front of the 3x we automatially know there is no reflection so that rules out answers A and B. Then, since 3 is greater than 1 we can determine that it is a stretch which would rule out answer C so the answer is D

muminat
2/5 and 1/3 have a common denominator of 15. 6/15, 5/15, and 4/15 add up to 15/15. So the chances of rock are 4/15. 120 divided by 15 is 8. Six times eight equals fourty eight, five times eight equals forty, and four times eight equals thirty two. So there are 48 classical songs, 40 jazz songs, and 32 rock songs.

Which expression is equivalent to 12(2+3x−6) ?
matrenka [14]
Simplify: 12(2 + 3x - 6)
= (12)(2 + 3x + - 6) = (12)(2) + (12)(3x) + (12)( - 6)
= 24 + 36x - 72
Answer = 36x - 48



2: Factor: 

36x - 48 
= 12(3x -4)

Answer 
= 12(3x -4)



3: <span>12(2+3x−6)

= 12(3x + 2 - 6)

= 12(3x - 4)


Your Answer  would be (A).

3x - 4</span>
