The function 
is an exponential with base greater than 1. So, its range is 
, with 0 being the horizontal asymptote as 
.
If you multiply the function by 
, the range remains the same.
If you reflect it over the x-axis, you're changing the sign of the function. So, the new range is
Answer:
A
Step-by-step explanation:
isnt it just A right?
8/15 = 56/105
This may be solved using proportion.
a/b = c/d
ad = bc where cross products are equal.
a = 8
b = f
c = 56
d = 105
ad = bc
8*105 = f*56
840 = 56f
840/56 = 56f/56
f = 15
56 ÷ 7 = 8
105 ÷ 7 = 15
Answer:
we know that, 1miles/hour = 0.45m/s
or, 1meters/second = 1/0.45
1m/s = 2.22222222222
Step-by-step explanation:
Then,
72.0 meters/second = 72.0*2.22222222222
=160 miles per hour.
Answer:
144
Step-by-step explanation:
f(4)=3*4^2
f(4)=12^2
12*12=144
