Point B is located at (-6, 5)
Multiply each coordinate by the scale factor 3 to get
-6*3 = -18
5*3 = 15
The point B' is located at (-18, 15)
Answer:
22. 6
23. 8^x
24. log2(16^5) = log2((2^4)^5) = log2(2^20) = 20
25. 2x + 1
27. log4(16^(x - 1)) = log4((4^2)^(x - 1)) = log4(4^(2x - 2)) = 2x - 2
28. 17
Answer:
3x = 12 + 24
Step-by-step explanation:
#2) Use quotient rule
Remember for solving log equations:
#3) Derivative of tan = sec^2 = 1/cos^2
Domain of tan is [-pi/2, pi/2], only consider x values in that domain.
#4 Use Quotient rule
#9 Use double angle identity for tan
This way you can rewrite tan(pi/2) in terms of tan(pi/4).
Next use L'hopitals rule, which says the limit of indeterminate form(0/0) equals limit of quotient of derivatives of top/bottom of fraction.
Take derivative of both top part and bottom part separately, then reevaluate the limit. <span />
