Step-by-step explanation:
i think this is right
Using trigonometry (SOHCAHTOA), <WZX is our main angle that we will be using. Our H or hypotenuse is the ZX or 7 because it is longest side in the triangle XZW, the A or adjacent is ZW or X. Then you set up your equation using the CAH of SOHCAHTOA and solve. To find WX, you use the same H or hypotenuse is the ZX or 7 because it is longest side in the triangle XZW and the O or opposite is WX which is your X. For setting up your equation you use the SOH of SOHCAHTOA and solve. You then double each of your measurements you got for ZW and WX and add them together to get your perimeter. Good luck! Let me know if you still need help!
Answer:
Step-by-step explanation:
I'm sure you want your functions to appear as perfectly formed as possible so that others can help you. f(x) = 4(2)x should be written with the " ^ " sign to denote exponentation: f(x) = 4(2)^x
f(b) - f(a)
The formula for "average rate of change" is a.r.c. = --------------
b - a
change in function value
This is equivalent to ---------------------------------------
change in x value
For Section A: x changes from 1 to 2 and the function changes from 4(2)^1 to 4(2)^2: 8 to 16. Thus, "change in function value" is 8 for a 1-unit change in x from 1 to 2. Thus, in this Section, the a.r.c. is:
8
------ = 8 units (Section A)
1
Section B: x changes from 3 to 4, a net change of 1 unit: f(x) changes from
4(2)^3 to 4(2)^4, or 32 to 256, a net change of 224 units. Thus, the a.r.c. is
224 units
----------------- = 224 units (Section B)
1 unit
The a.r.c for Section B is 28 times greater than the a.r.c. for Section A.
This change in outcome is so great because the function f(x) is an exponential function; as x increases in unit steps, the function increases much faster (we say "exponentially").
