This is indeed a polymomial, it's just not in the correct order. The term with the highest exponent goes first, dictating the degree of the whole entire polynomial. In descending order, the polynomial is written correctly as

. It is a third degree polynomial with a leading coefficient of -2.
Hello,
1)
tan (a-b)=(tan a - tan b)/(1+tan a tan b)
15=45-30
tan 45°= (√2/2)/(√2/2)=1
tan 30°=(1/2)/(√3/2)=√3/3
tan (45°-30°)= (1-√3/3)/(1+1*√3/3)=(3-√3)/(3+√3)=(3-√3)²/6=2-√3
tan (-105°)=tan (75°)= tan (60°+15°)=(tan 60+tan15°)/(1-tan 60°*tan 15°)
tan 15°=2-√3
tan 60°=√3°
tan (-105°)=(√3+2-√3)/(1-√3*(2-√3))=2/(1-2√3+3)=1/(2-√3)=2+√3
You should first equate the powers by the volume you get the depth and then you need to find the rest by resulting breadth
A function assigns values. The inequality one-half x minus 10 greater-than-or-equal-to 0 should be satisfied.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
The domain of a function is a set of values for which the equation is satisfied. Since the function has under root values, the value which is under the root should be non-negative so that it does not give a complex number, therefore,
The inequality
satisfied to find the domain of the function f(x).
Also, we can write that 0.5x²-10≥0 for the value to be positive.
Hence, the inequality one-half x minus 10 greater-than-or-equal-to 0 should be satisfied.
