Answer:
B. -6
Step-by-step explanation:
The common difference here is the difference between each term. Since it is an arithmetic sequence the difference between each term will be the same value.
So, from 45 (the 1st term) to 39 (the 2nd term), the difference is -6
From 39(the 2nd term) to 33, the difference is also -6.
Therefore, we know that the common difference fro this arithmetic sequence is -6.
Hope this helps and ask me any question if it does not :)
Answer: f⁻¹(x)=4x-56
Step-by-step explanation:
f⁻¹(x) is the inverse of f(x). To find the inverse, we replace the y with x, and x with y. Once we do that, we solve for y.
[subtract 14 on both sides]
[multiply both sides by 4]
[distribute 4]

ratio short leg : long leg : hypotenuse = a : a√3 : 2a (where a = short leg)
Answer is D.
4 , 4√3 , 8
short leg = 4
long leg = short leg times √3 = 4√3
hypotenuse = 2 times short leg = 2 * 4 = 8
