Q:
13. If \( \log _{c} 3 \approx 2.311 \), approximate \( \log _{c} 81 \)
Q:
Two laptops are available for purchase. The cost of the silver laptop can be modeled with the function \( f(t)=3,000(0.85)^{t} \), and the cost of the black laptop can be modeled with the function \( g(t)=3,500(0.7)^{t} \), where \( t \) is the tim in years. Your parents will help you buy the less expensive laptop, but you must choose within the next 2 years. Which statement below best represents the outcome? - You buy the silver laptop. - You buy the black laptop. - Both laptops cost the same amount.
Q:
Example 1: You are considering two used phones for purchase. The cost of the first phone can be modeled with the function \( f(t)=1,500(0.8)^{t} \), and the cost of the second phone can be modeled with the function \( g(t)=2,000(0.6)^{t} \), where \( t \) is the time in years. Your budget is limited, and you plan to buy the less expensive phone in the next 3 years. Which statement below best represents the outcome? - You buy the first phone. - You buy the second phone. - Both phones cost the same amount.
Q:
19. Under ideal conditions, a population of rabbits has an exponential growth rate of \( 11.7 \% \) per day. Consider an initial population of 100 rabbits. How long before we have 500?
Q:
7. The number of pages in the IRS Tax Code has followed the function \( T(n)=400(1.055)^{n} \), where \( n \) is the number of years since 1913. Based on this, predict the number of pages in the tax code in 2015 .
Q:
63-68 - Encuentre el dominio de la función. .63. \( f(x)=\log _{10}(x+3) \) 65. \( g(x)=\log _{3}\left(x^{2}-1\right) \) 67. \( h(x)=\ln x+\ln (2-x) \)
Q:
53-62 - Grafique la función, no al localizar puntos sino empezando de las gráficas de las Figuras 4 y 9. Exprese el dominio, rango y asintota. 59. \( y=1-\log _{10} x \)
Q:
\( \left(x+\frac{\pi}{4}\right)-\cos x=0 \) em \( [-\pi, \pi[ \)
Q:
53-62 : Grafique la función, no al localizar puntos sino empezando de las gráficas de las Figuras 4 y 9 . Exprese el dominio, rango \( y \) asíntota. .53. \( f(x)=\log _{2}(x-4) \) .55. \( g(x)=\log _{5}(-x) \) .57. \( y=2+\log _{3} x \) 59. \( y=1-\log _{10} x \) 61. \( y=|\ln x| \)
Q:
The domain is all real numbers, and the range is \( y \leq 0 \). The domain is \( x>0 \), and the range is all real numbers. The domain and range are all real numbers. The domain is \( x<0 \), and the range is \( y>0 \).
