F(x)=x^2. What is g(x)?
Contact [7]

Answer:

Do you have options? The answer would be

g(x)=(x/3)^2

x = 1 btw

Because x = 1, if you have options then it'll most likely be g(x)=(1/3]^2

Step-by-step explanation:

Hope this helps

Can Someone explain how to do this?
zheka24 [161]
1 equals 2. So 2 would be 50 as well.
50+50=100
And there's 360 degrees in total so you'd then subtract 360-100= 260
Then divide by 2 since the other 2 angles are the same
260/2=130
1=50
2=130
3=130
Hope this makes sense! :)

Find the value of each variable:
Leona [35]

Answer:

5√3 = b

5 = d

10√3 = a

15 = c

Step-by-step explanation:

Sin60° = opp/hyp

sin60° = b/10

10sin60° = b

5√3 = b

Cos60° = adj/hyp

Cos60° = d/10

10Cos60° = d

5 = d

Sin30° = opp/hyp

Sin30° = 5√3/a

a = 5√3/Sin30°

a = 10√3

Tan30° = opp/adj

Tan30° = 5√3/c

c = 5√3/tan30°

c = 15
