Answer:
14 is the answer.
Step-by-step explanation:
Answer:
5/4
Step-by-step explanation:
(10/12) / (4/6)
Reduce the fractions:
(5/6) / (2/3)
Multiply by the reciprocal:
(5/6) × (3/2)
15/12
Reduce:
5/4
It is quadratic equation.
First we have find delta given by formula: delta=

where our
a=16
b=-24
c=7
so, delta=

Because delta is positive, there is real results.
Now we can use next formula x=

, to find roots (results, 2 results because its quadratic equation and delta is greater than 0)
x1=

x2=
We know the following relationship:

The
domain of a function are the
inputs of the function, that is, a function

is a relation that assigns to each element

in the
set A exactly one element in the
set B. The set A is the domain (or set of inputs) of the function and the set B contains the range (or set of outputs).Then applying this concept to our function

we can write its domain as follows:
1. D<span>

When:

?
when:
where k is an integer either positive or negative. That is:

To match this with the choices above, the answer is:

2. which identity is not used in the proof of the identity 
:
This identity can proved as follows:

The identity that is not used is as established in the statement above:

The answer is D) The car travels 53 mph(Miles Per Hours).
212/4 = 53
318/6 = 53
424/8 = 53
530/10 = 53
