Answer:

4m

Step-by-step explanation:

We are looking for the circumference

We need to find the radius

r = d/2 = 1.2/2 = .6

C = 2*pi*r

C = 2*pi*(.6)

C = 1.2*pi

We can approximate pi by 3.14

C =1.2*3.14

C =3.768 m

To the nearest meter

C = 4m

Answer:

The value of f(2) would be -40.

Step-by-step explanation:

Given function is,

f(x) = 2x^3 - 3x^2 - 18x - 8

Substituting x = 2 in the above function,

We get,

f(2) = 2(2)^3 - 3(2)^2 - 18(2) - 8

=2(8) - 3(4) - 36 - 8

=16 - 12 - 44

\implies f(2)= -40

Hence, the value of f(2) would be -40.

Mia opens a coffee shop in the first week of January. The function W(x) = 0.002x3 - 0.01x2 models the total number of customers
Mashcka [7]
Writing the two equations in full and subtracting R(x) from W(x) to arrive at D (x) gives the answer. This is shown below;

W(x) = 0.002x^3 - 0.01x^2 + 0x + 0
R (x) =        0x^3 +       x^2 - 4x +13 -
-----------------------------------------------
D(x) = 0.002x^3 -1.01x^2 + 4x - 13
