Fountain
A = pi * 10^2
A = 100pi
Garden
A = pi * 200^2
A = 40,000pi
40,000pi - 100pi = 39,900 m^2
Answer:
the answer is c :)
Step-by-step explanation:
Answer:
(a) This is just `8` people being arranged in a row: `8! = 40,320` (b) Regard the `2` boys as one "unit" and so there are `7` "units" to arrange. This can be done `7! = 5040` ways. The boys can be arranged in `2! = 2` ways, so the required answer is `7! × 2! = 10,080` (c) There are only `2` possibilities: the boys are together or they are not.
Step-by-step explanation:
Answer:
y =
x + 7
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m =
, hence
y =
x + c ← is the partial equation
to find c substitute (4, 9) into the partial equation
9 = 2 + c ⇒ c = 9 - 2 = 7
y =
x + 7 ← equation in slope-intercept form
