Answer:
A. True
Step-by-step explanation:
All function of the form y = a^x, where a is a positive constant, goes through the point (0,1) and y = 0 is the asymptote.
Also note, a function y = a^x + k is a vertically translated function from the parent (y=a^x) k units up.
So, the function F(x) = 7 + 3^x is basically 3^x translated 7 units. What happens is that the point (0,1) gets translated 7 units above, so this point becomes (0,1+7)=(0,8). and the asymptote is y = 7.
Hence the function starts from above y = 7 (y = 7 is asymptote), goes through (0,8) and increases. Hence the Range would be all numbers GREATER than 7 (till infinity).
So, the question is TRUE.
Answer:
9:40 am
Step-by-step explanation:
Let time taken from when Smith left compound to when Garcia overtakes Smith's car be represented by y
After y hours, Smith has covered 48*y=48y miles
Similarly, due to a difference of 20 minutes which is 20/60=1/3 hours, Garcia moves a distance of
60(y-1/3)
Equating both distances to be the same
60y-20=48y
12y=20
y=20/12=5/3 hours
Converted to minutes
5/3*60=100 minutes= 1 hr 40 mins
Therefore, adding 100 minutes to to starting time of Smith
8:00+1:40=9:40 am
The time that Garcia overtakes Smith is 9:40am
