If f(x) = [x] – 5, what is f(8.6)?<br> 3<br> 4<br> 8<br> 9
shutvik [7]

Answer:

Step-by-step explanation:

The strange thing about the greatest integer function is that the number you are evaluating the function at is not actually the number unless its an integer.  The rule is to round down, ALWAYS, if you are dealing with a value of x that is not an integer.  In other words, you are NOT evaluating the function at 8.6, you have to round down to 8 and evaluate it there.  8 - 5 = 3

write the product of the expression 5^4 * 5^-7 using a positive exponent, then write the product using a negative exponent
pav-90 [236]

Answer with positive exponent = \left(\frac{1}{5}\right)^3 or  \frac{1}{5^3}

Answer with negative exponent = 5^{-3}

===========================================================

Explanation:

The rule we use is

a^b*a^c = a^{b+c}

If we multiply two exponential expressions with the same base, then we add the exponents.

The base for each is 5. The exponents 4 and -7 add to -3.

This means

5^4*5^{-7} = 5^{4+(-7)} = 5^{-3}

To convert to a positive exponent, we apply the reciprocal to the base. We go from 5, aka 5/1, to 1/5.

So, 5^{-3} = \left(\frac{1}{5}\right)^3 = \frac{1^3}{5^3} = \frac{1}{5^3}

Cole says that all quadrilaterals are polygons but not all polygons are quadrilaterals is he correct explain������
zepelin [54]
YES, this is correct. All quadrilaterals whether is a trapezoid, parallelogram, rhombus and others, they are all polygons and all they have 4 sides and 4 angles. We know that a polygon is a figure with at least three sides and three angles.

Not all polygons are quadrilateral, this is also correct since some polygons have five or more sides and angles.
