The ascending or descending order of a polynomial is
determined by the increasing or decreasing power of variable “x” respectively.
<span>The question is to find about the polynomial in
descending order, so in this case, the 3rd option is correct, i.e.
4x^2 – 3x + 9 or 4x^2 – 3x^1 +9x^0. The power of “x”
decreasing from 2 to 1 and then finally to 0.</span>
The domain of the function f(x) is where the area under the square root (aka the radicand) is positive or zero. We have to write that the radicand is greater than or equal to zero, so

Answer:
Yes
Step-by-step explanation:
90% of 50 is 40 so if more than 40 left before it hit 60 seconds then the 90% has been achieved.
I assume the question is multiply to -50 and add to +5... If so, the answer is +10 and -5. 10 (-5) = -50 .... and 10 + (-5) = +5
The cost of the metals from the calculations performed is $ 402421.
<h3>What is density?</h3>
Density can be explained as a quantity having mass per unit volume and this can be calculated as:
Mass of the metal = ?
Density of the metal = 7.3 g/cm^3
height of the metal = 610 cm
radius of the metal = 8.7 cm
Volume of a cylinder can be calculated by using the formular below:
And this can be used by inserting the given values which is

Then we can calculate the mass as :
Mass = (density * volume)

=Since the cost is $0.38 per kilogram, then 3657 Kg costs
;( 1059003kg * $0.38)
= $ 402421
