Take the log (base 4) of both sides of the equation.



The appropriate choice is ...
m = -11/4
F(X)=13 Just Plug 10 into the X in the equation
The area of the metal strips:
A = L * W , where L stays for length and W stays for wirth.
A = 11 ft * 2 ft ;
A = 22 ft^2.
If it costs $6 per foot:
Total cost = 22 * 6 = $132.
Answer: The total cost of a metal strip is $132.
Volume of a spehere=(4/3)πr³
Data:
diameter=3.5 in
π=3.14
1)we calculate the radius:
r=diameter/2=3.5 in / 2=1.75 in
2) we calculate the volume of this sphere:
volume=(4/3)*3.14*(1.75 in)³=22.4379...in³≈22.44 in³.
Answer: 22.44 in³
