The correct answer for the question that is being presented above is this one: "The axis of symmetry is to the left of zero." The a value of a function in the form f(x) = ax2 + bx + c is negative. The statement must be true is this The axis of symmetry is to the left of zero.<span>

1 inch = 2.54 cm
27 feet 10 inches = 27 * 12 + 10 = 334 inches.
334 inches = 334 inches * 2.54 cm / inch = 848.36 cm
1 meter = 100 cm
x = 848.36 cm
Cross multiply
848.36 cm * 1 meter = 100 cm * x Divide both sides by 100
848.36 cm* meter/ 100 cm = x
8.48 meter = x
Answer 8.48 meters.
I think the answer would be 24 but im not 100% sure
Option a:
is the equivalent expression.
Explanation:
The expression is
where 
Let us simplify the expression, to determine which expression is equivalent from the four options.
Multiplying the powers, we get,

Cancelling the like terms, we have,

This equation can also be written as,

Multiplying the terms in denominator, we have,

Thus, the expression which is equivalent to
is 
Hence, Option a is the correct answer.
Answer:



Step-by-step explanation:
Step 1: Pythagoras Theorem
Pythagoras theorem relates the three sides of the triangle in such a way that the sum of the square of base and perpendicular is equal to hypotenuse, such as:

Step 2: Trigonometric Functions
Only for a right angle triangle following three trigonometric relations are valid



Step 3: Verifying all the possible answers
A: Since, LN = x and using 
we can calculate


therefore, NM = x (true)
B: As NM = x therefore it can not be equal to
.
C: Using Pythagoras Theorem



It can also be proved using trigonometric relation


As, 
Therefore

D and E:
Using same approach similar to part A
Since, LN = x and NM = x
we can calculate


Therefore,
and not equal to
