60 = 5(1.07)^x initial value:

a. 7%

b. 1.07%

c. 9.3%

d. 5

e. 60

growth or decay?

growth/decay rate?

a. 7%

b. 1.07%

c. 9.3%

d. 5

e. 60

Given:

The given equation is

To find:

The initial value and growth/decay factor.

Solution:

The general exponential growth/decay model is

    ...(i)

where, a is initial value, if r>0, then |r| is growth factor, if r<0, then |r| is decay factor and x is time.

We have,

It can be written as

       ...(ii)

On comparing (i) and (ii), we get

Here, initial value is 5 and growth factor is 0.07, i.e., 7%.

Therefore, the correct option for first question is d and correct option for second question is a.

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
