So you make them the same common denominator
As you see, 2/10 = 8/40
2/4 = x/40, multiply by 10
2/4 = 20/40
Then add because same denominator
Now you would get:
8/40 + 20/40 = 28/40
A(n,s)=(ns^2)/(4tan(180/n)), n=number of sides, s=side length
A(8,4.6)=(8*4.6^2)/(4tan22.5)
A(8,4.6)=42.32/tan22.5 m (exact)
A(8, 4.6)≈102.17 m^2 (to nearest hundredth of a square meter)
12 I got it form Socratic
Use this equation:
A = P(1+r)^t
Where A is the final amount
P is the initial amount
r is the annual rate
t is the time in years
P = 1500
r = 0.07
t = 3
A = 1500 (1.07^3)
≈ $1837.56
Have an awesome day! :)
Answer:
y = -x/3 + 5/3
Step-by-step explanation:
In order to find the inverse of a function, you have to switch the x and y values, and then solve for y again.
f(x)=-3x+5
y = -3x + 5
x = -3y + 5
x + 3y = 5
3y = 5 - x
3y = -x + 5
y = -x/3 + 5/3
