Answer:
$53750
Step-by-step explanation:
Sam deposit $12500 every year which grows at a simple interest of 3% and we have to calculate the total sum after 4 years.
If Sam deposit $x with r% simple interest then the principal will grow after 4 years to
Again, for the second year $x investment with r% simple interest will grow to .
Now, the third year $x investment with r% simple interest will grow to
And finally the fourth year $x investment with r% simple interest will grow to
Therefore, the total sum becomes
=
=
So, in case of Sam the sum will be = = $53750
(-13 * -2) + (15*-2) - (4*-2)
26-30+8
=4
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.
Answer:
y = 3x
Step-by-step explanation:
A proportional function has the equation
y = kx, where k is the constant of proportionality and also the slope of the line.
Answer: y = 3x
Answer:
45 dollars for going over 2GB
Step-by-step explanation:
If he pays 25 dollars every month and he goes over 2 GB then he’ll have to pay 20 dollars extra since every GB over cost 10 dollars. The equation is 25+10+10 which equals 45.
