Well first solve for x
2x + 3 = -19
2x = -22
x = -11
Therefore yes, -11 is a solution for the function.
The volume of a square pyramid can be derived from the expression that the volume of an object is equal to the product of the area of the base times its height. For a square pyramid, it can be simplified as V = a^2(h)/3 where a is the side of the square base and h is the height. However, we are given the slant height. The equation would be:
V = a^2(h)/3
s^2 = (a/2)^2 + h^2 where s is the slant height
h = √( s^2 - (a/2)^2)
h = √( 26^2 - (48/2)^2)= 10
V = 48^2(10)/3 = 7680 cm^3 --> OPTION C
It belongs to the set of real numbers
and as it can be written as a fraction then it is also a rational number.
Area formula: pi * radius * radius
Radius=1/2diameter=1/2(7)=3.5
3.5*3.5*pi=12.25pi square feet
Circumference formula: pi * diameter
7*pi=7pi feet
