Answer:
tanx·secx
Step-by-step explanation:
To simply this, you can begin by factoring sin x out of the numerator to become:
Now, using Pythagorean Trig Identities, we know that sin²x+cos²x equals 1. We can substitute this to make the equation become:
First of all, we can convert to tanx. However, we have a remaining
which, using reciprocal identities, will become sec x.
Finally, we get our answer as tanx·secx.
Answer:
Step-by-step explanation:
Definition : The expression that can have constants (like 4), variables (like x or y) and exponents (like the 2 in ), that can be combined using addition, subtraction, multiplication and division, but no division by a variable and a variable's exponents can only be 0,1,2,3,... etc. and it can't have an infinite number of terms.
1. 6 + p
Being p be a variable this equation is polynomial
2. x – 1
Since x-1 has variable and constant so according to definition it is a polynomial
3. 8x−z3
According to definition it is a polynomial
4 .
Since has root so it is not a polynomial .
Answer:
B.
Step-by-step explanation:
<em><u>To find the perimeter, use the formula:</u></em>
P = a + b + c
P = 12 + 12 + 9.7
P = 33.7
<em><u>To find area, use the formula:</u></em>
A =
A =
A =
A = 54
