The 4 treads require 4*10.25 = 41 inches, but you also require landings at each level, adding perhaps 72 inches. (Building codes vary.)
Somewhere between 41 and 113 inches of horizontal space will be required, perhaps more.
Answer:
9600 cm³
Step-by-step explanation:
volume of water=60×80×25
volume of water +volume of rock=60×80×(25+2)=60×80×25+60×80×2
volume of rock=60×80×25+60×80×2-60×80×25=60×80×2=9600 cm³
Answer:
It is quadratic.
The constant term is:-12
Step-by-step explanation:
1. You can apply the Distributive Property of multiplication, as following:
![f(x)=(3x-6)(-4x+2)\\f(x)=(3x)(-4x)+(3x)(2)+(-6)(-4x)+(-6)(2)\\f(x)=-12x^{2}+6x+24x-12\\f(x)=12x^{2}+30x-12](https://tex.z-dn.net/?f=f%28x%29%3D%283x-6%29%28-4x%2B2%29%5C%5Cf%28x%29%3D%283x%29%28-4x%29%2B%283x%29%282%29%2B%28-6%29%28-4x%29%2B%28-6%29%282%29%5C%5Cf%28x%29%3D-12x%5E%7B2%7D%2B6x%2B24x-12%5C%5Cf%28x%29%3D12x%5E%7B2%7D%2B30x-12)
2. The function has the form:
![f(x)=ax^{2}+bx+c](https://tex.z-dn.net/?f=f%28x%29%3Dax%5E%7B2%7D%2Bbx%2Bc)
Therefore, it is a quadratic function, where
is the constant term.
3. Therefore, the constant term is -12
Answer:29,858
Step-by-step explanation:

A triangle has three angles, and their measures add up to 180 degrees.
An isosceles triangle has at least 2 congruent sides, and the angles opposite the congruent sides are congruent.
This triangle has one angle of 40 deg, and two angles that measure the same; call the measure of each base angle x.
x + x + 40 = 180
2x + 40 = 180
2x = 140
x = 70
The base angles measure 70 deg.
