Step-by-step explanation:
Answer:
It will take 4 hours to dig in the garden
Step-by-step explanation:
First we have to calculate the diameter, for this we will use the formula to calculate the circumference of a circle and we will clear the diameter
d = diameter
π = 3.14
c = circumference
c = π * d
d = c / π
d = 88yd / 3.14
d = 28.025yd
round to the nearest whole number
28.025 = 28
d = 28yd
To know how many hours it takes, we divide the diameter by the speed
t = time
v = velocity
t = d / v
t = (28yd) / (7yd/h)
t = 4h
It will take 4 hours to dig in the garden
Answer:
Step-by-step explanation:
Look at both terms separately, and isolate each "part."
i.e. 12x^4y^2 becomes 12, x^4, y^2
So the problem becomes:
12, x^4, y^2 and
30, x^3, y^1
Then, find the GCF of each term,
30 and 12 - 6
x^4 and x^3 - x^3
y^2 and y^1 - y^1
Hope it helps :) and let me know if you want me to elaborate.
The correct answer is f^-1(x)=1/2x+2.
1. Substitute y for f(x). ( y=2x+4 )
2. Interchange the variables x and y. ( x=2y-4 )
3. Swap the sides. ( 2y-4=x )
4. Move the constant to the right. ( 2y=x+4 )
5. Divide both sides by 2. ( y=1/2x+2 )
6. Use substitution to substitute f^-1(x) for y.
Thus the inverse is f^-1(x)=1/2x+2
