(1 & 2/3) ft = (1 ft) + (2/3 ft)
(1 & 2/3) ft = 12 inches + 12*(2/3) inches
(1 & 2/3) ft = 12 inches + 8 inches
(1 & 2/3) ft = 20 inches
If the tree grows 5 inches per year, then it will take 4 years to get to 20 inches since 5*4 = 20. You can also divide to get 20/5 = 4.
So it takes 4 years for the tree to grow 1&2/3 feet tall.
using 3.14 for pi
area = pi x r^2
since he can see 12 miles in any direction 12 would be the radius
so 3.14 x 12^2 = 452.16 square miles
round the answer as needed.
The formula is
A=p (1+r/k)^kt
A future value?
P present value 874
R interest rate 0.032
K compounded quarterly 4
T time 7 years
A=874×(1+0.032÷4)^(4×7)=1,092.46
Answer:
Given in the question an expression,
y = 3x/(8+x)
Step1
interchange the variables
x = 3y/(8+y)
Step 2
x(8+y) = 3y
Step 3
8x + xy = 3y
Step 4
8x = 3y - xy
Step 5
8x = y(3 - x)
Step 6
8x = y(3 - x)
Step 7
y = 8x/(3-x)
Step 8
y = f(x^-1) = 8x/(3-x)
So the inverse of f(x)= 3x/(8+x) is f(x^-1) = 8x/(3-x)
