Answer:
√55 ≈ 7.4
Step-by-step explanation:
The easiest way to find the square root of 55 is to use a calculator.
√55 ≈ 7.4161984871
Rounded to the nearest tenth, this is ...
√55 ≈ 7.4
__
You can make a first approximation of the root by linearly interpolating between the roots of the perfect squares* on either side of 55.
√49 = 7
√64 = 8
√55 ≈ 7 +(55 -49)/(64 -49) = 7 6/15 = 7 2/5
√55 ≈ 7.4
_____
* For numbers greater than 3.3, this sort of approximation will give the value of the root accurate to the nearest tenth. The approximation is better for larger numbers.

Refer to the diagram shown below.
The right vertex is at (14, -1), and the center is at (-1, -1).
Therefore the semi-major axis is
a = 14 - (-1) = 15
The right focus is at (8, -1).
Therefore
c = 8 - (-1) = 9.
The distance of the directrix from the center is
d = c²/a = 9²/15 = 81/15 = 27/5.
Therefore the equation for the left directrix is
x = -1 - 27/5 = -32/5
Answer: x = -27/5
Answer:
In the procedure
Step-by-step explanation:
we know that
A polynomial which has only one term is called monomial
The degree of a monomial is defined as the sum of all the exponents of the variables
<em>Examples</em>
If the monomial has only one variable
3x² -----> is a monomial of the 2 degree with a leading coefficient of 3
If the monomial has more than one variable
3xy ----> is a monomial of the 2 degree with a leading coefficient of 3
$396.66/24 students = $16.5275 which could be rounded to $16.53
