2. A new type of cell phone is being released to the public. The function below is used to predict F(t), the total sales in thousands of units per day based on t, the
time in weeks since the date of release.
S(O)= 40 (1.18)
O
118,000 units on the first day then 40% per week
40,000 units on the first day then 18% per week
According to this function, what are the predicted sales on the first day, and
what is the predicted rate of percentage increase per week in the sales
40,000 units on the first day then 1.18% per week
amount?
18,000 units on the first day then 40% per week

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

step-by-step explanation:

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
