The cost of a pound of strawberries at a local market increases at a rate of 2.1% per year due to greater agricultural costs. The following exponential expression gives the cost of a pound of strawberries after t years.
3.50(1.021)
Which of the following expressions reveals the monthly rate of increase for the cost of a pound of strawberries?
O (1.002)^t/12
0 (0.998)^t/12
0 (0.998)^12t
(1.002)226
(1.002)^12t

the infinity sign

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
