Use the unit circle. Of the choices given, only cos 45 and sin 45 are equal to positive sqrt2/2.
Answer:
a
Step-by-step explanation:
Option C is correct because it is a trinomial with a leading coefficient of 3 and a constant term of -5
Step-by-step explanation:
We need to pick the expression that matches this description:
A trinomial with a leading coefficient of 3 and a constant term of -5
First lets explain the terms:
Trinomial: a polynomial having 3 terms
Leading coefficient: The constant value of variable having highest power
Constant term: Having no variable and value cannot be changed.
Now using these definitions, we can choose the correct option
Option A is incorrect because the expression has 2 terms
Option B is incorrect because it is a trinomial but the leading coefficient is -5 and not 3 constant term is 3 and not -5.
Option C is correct because it is a trinomial with a leading coefficient of 3 and a constant term of -5
Option D is incorrect because it is a trinomial but the leading coefficient is 3 but constant term is 1 and not -5.
So, Option C is correct.

The volume of the cylinder by definition is given by:
V = Ab * h
Where,
Ab: base area
h: height
Substituting values we have:
140 = Ab * 12
To find the area, the first step is:
Pass the 12 dividing.
Answer:
the correct first step in finding the area of the base of a cylinder is:
Pass the 12 dividing.
