I think you mean y=ab^x.
First, plug in the values of x=2 and y=24 for the first equation, and x=3 and y=48 for the second one:
24 = ab^2
48 = ab^3
divide equation 2 by equation 1:
2 = b^1
or, more simply:
2 = b
now plug b into one of the equations to get "a":
24 = a*2^2
24 = a*4
6 = a
So, the answer is y = 6(2)^x
(I think you need to specify the power of x in your answers)
D. 35 is the answer. Since we know that 14=2k based on the knowledge given in the first part of the equation, we can solve for K. We learn that K=7. Then, we can substitute K into the second equation: y=(7)(5) which is 35.
Volume of the orange juice in the carton = 10*6*8 = 480 cm^3
when its turned on its side we have the equation 6*20*h = 480 where h = required height
h = 480 / (6*20) = 480 / 120 = 4 cms
answer = 4 cm
Answer:
cubic units
Step-by-step explanation:
Given is a function exponential as
The region bounded by the above curve, y =0 , x =13 is rotated about x axis.
the intersection point is at x=4
The limits for x are 4 and 13
The volume when rotated through x axis is found by
Here a = 4 and b =13
volume = 
=
.cubic units
Takes the s 1 h 15 m for 1 3/5 miles
so
75 min divided by 1.6= about 46 min
i am not completely sure if its correct
