Danny charges $40 for 4 hours of swimming lessons, Martin charges $85 for 5 hours of swimming lessons. Who offers a better deal?

Answer:

Danny does

Step-by-step explanation: 40 / 4 = 10

                                              85 / 5 = 17

10 is less than 17 meaning that Danny is offering a better deal.

What is the answer for this question??? i need it
JulijaS [17]

Answer:

f(4)=14

Step-by-step explanation:

a) u do it by substituting 4 in places where there r 'x'

since this one say f(4) it only can go to the function which says f(x)
f(x)=4x-2
f(4)=4(4)-2, so according to BODMAS rule multiplication comes first rather than subtraction

so, f(4)=16-2=14
f(4)=14
do the others based on this, hope i explained well, if i did, please gimme brainliest :)

Help asap, will mark brainliest

Thanks for clarifying the function

f(x) = 4\cdot 2^x

Part A.

The average rate of change is the change in y over the interval divided by the change in x over the interval. The change in x is just the length of the interval.

So section A, the average from 1 to 2 is

a =\dfrac{ f(2) - f(1) }{2 -1 } = \dfrac{ f(2)-f(1)}{1} = 4 (2^2) - 4(2^1) = 16 - 8 = 8

Section B, the average from 3 to 4 is

b =\dfrac{f(4) - f(3)}{4-3} = \dfrac{f(4)-f(3)}{1} = 4 (2^4) - 4(2^3) = 4(16)-4(8) =64-32=32

Part B.

Section B is changing (32/8=) four times faster than section A.

f is an exponential function that not only increases its value but increases the rate at which it increases its value. Each step of one unit in x doubles the rate of increase. Here we stepped two units, from [1,2] to [3,4], so quadrupled the rate.
