Forks :
20 x 12 = 240
Spoons:
10 x 12 = 120
Knives :
5 x 10 = 50
Paper plates :
175
Total :
175 + 50 + 120 + 240 = 585

Step-by-step explanation:
A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
This means that if the object x
x
is in the set of inputs (called the domain) then a function f
f
will map the object x
x
to exactly one object f(x)
f
(
x
)
in the set of possible outputs (called the codomain).
The notion of a function is easily understood using the metaphor of a function machine that takes in an object for its input and, based on that input, spits out another object as its output.
Example: x2 (squaring) is a function
x3+1 is also a function
Sine, Cosine and Tangent are functions used in trigonometry
and there are lots more!
But we are not going to look at specific functions ...
... instead we will look at the general idea of a function.
x = length of one side.
1,232in^2 = x^2
Take the sqrt of both sides.
35.1 in = x
The length of one side = 35.1 in
Answer:
Here's what I get
Step-by-step explanation:
Stretch
(i) The equation
E = 250 000 + 100 000n
(ii) Variables
n = the number of games played
E = Stretch's total earnings in dollars
(iii) Constants
$250 000 = Stretch's signing bonus
$100 000 = the money earned for each game.
The graph shows how Stretch's total earnings vary with the number of games played.
(iv) Total earnings after 44 games
Rory
E = 95 000n + 450 000
Rory's deal is better than Stretch's if they play fewer than 40 games.
He starts off with a bigger signing bonus, but Stretch earns more money per game.
Stretch closes the gap with each game played.
By 40 games they have the same total earnings.
After 40 games Stretch has more total earnings.
