When the burner is off there is no energy being produced.
Once you turn the burner in it begins creating energy which is used to cook.
The answer is: newly created energy that was not present earlier.
Answer:
€2.24
Step-by-step explanation:
Let, the potatoes be x and apples be y
A/c to question,
4x = 3.80
x = 0.95
And,
3x + 2y = 7.33
3*0.95 + 2y = 7.33
2y = 7.33 - 2.85
y = 4.48/2
y = €2.24
Hence, the cost of 1 kg apple (y) = €2.24
Answer: B (3 cups)
Step-by-step explanation:
Add 2 cups + 1 cup together, and you get 3 cups. C is incorrect (in this scenario) because it doesn’t describe what measurement it’s in.
See explanation below.
Explanation:
The 'difference between roots and factors of an equation' is not a straightforward question. Let's define both to establish the link between the two..
Assume we have some function of a single variable
x
;
we'll call this
f
(
x
)
Then we can form an equation:
f
(
x
)
=
0
Then the "roots" of this equation are all the values of
x
that satisfy that equation. Remember that these values may be real and/or imaginary.
Now, up to this point we have not assumed anything about
f
x
)
. To consider factors, we now need to assume that
f
(
x
)
=
g
(
x
)
⋅
h
(
x
)
.
That is that
f
(
x
)
factorises into some functions
g
(
x
)
×
h
(
x
)
If we recall our equation:
f
(
x
)
=
0
Then we can now say that either
g
(
x
)
=
0
or
h
(
x
)
=
0
.. and thus show the link between the roots and factors of an equation.
[NB: A simple example of these general principles would be where
f
(
x
)
is a quadratic function that factorises into two linear factors.
