What is the exact value of Cosine (StartFraction 11 pi Over 21 EndFraction) cosine (StartFraction pi Over 7 EndFraction) minus sine (StartFraction 11 pi Over 21 EndFraction) sine (StartFraction pi over 7 EndFraction)?
Negative StartFraction StartRoot 3 EndRoot Over 2 EndFraction
Negative one-half
One-half
StartFraction StartRoot 3 EndRoot Over 2 EndFraction
Answer:
Option (2)
Step-by-step explanation:
Given trigonometric expression is,
[tex]\text{cos}(\frac{11\pi}{21})\text{cos}(\frac{\pi}{7})-\text{sin}(\frac{11\pi}{21})\text{sin}(\frac{\pi}{7})[/tex]
This expression is in the form of an identity,
cos(A + B) = cos(A)cos(B) - sin(A)sin(B)
By substituting the values of A = [tex]\frac{11\pi}{21}[/tex] and B = [tex]\frac{\pi}{7}[/tex] in the identity,
[tex]\text{cos}(\frac{11\pi}{21})\text{cos}(\frac{\pi}{7})-\text{sin}(\frac{11\pi}{21})\text{sin}(\frac{\pi}{7})[/tex] = cos[tex](\frac{11\pi}{21}+\frac{\pi}{7})[/tex]
= cos[tex](\frac{11\pi+3\pi}{21})[/tex]
= cos[tex](\frac{14\pi}{21})[/tex]
= cos[tex](\frac{2\pi}{3})[/tex]
= -[tex]\frac{1}{2}[/tex]
Therefore, Option (2) will be the answer.

Determine whether each expression is a polynomial. If so, identify the polynomial
as a monomial, binomial, or trinomial.
Answer:
1. is monomial
2. is binomial
3. is binomial
4. is trinomial
5. is trinomial
6. is binomial
Step-by-step explanation:
See...you need to know that the polynomial is determined by the number of unlilke terms in the expresion. i.e number of terms left that cant ne add subtracted or simplified anymore.
if its helpful send more quest om this...and domt forget brainliest
The expression shown are 1. Monomial 2. Not a polynomial 3. Binomial 4. Trinomial 5. Not a polynomial 6. Binomial
What is Polynomial?Polynomials are expressions of the form,
a₀ + a₁ x + a₂ x² + ................. + aₙ₋₁ xⁿ⁻1 + aₙ xⁿ
where a's are the coefficients, x is the variable and n is the number of terms.
1. 36
36 can be written as 36 x⁰.
This is a constant polynomial.
Since there is only one term, it is monomial.
2. [tex]\frac{3}{q^{2} }[/tex] + 5
This can be written as 3 q⁻² + 5.
The exponent of the variable is not a whole number, so is not a polynomial.
3. 7x - x + 5
This can be written as 6x + 5.
This is a polynomial and is binomial since there are two terms.
4. 8g²h - 7gh + 2
This is a polynomial in two variables.
This is a trinomial, as there are three terms.
5. [tex]\frac{1}{4y^{2} }[/tex] + 5y - 8
This can be written as 1/4 y⁻² + 5y - 8
This is not a polynomial as the exponent is not a whole number.
6. 6x + x²
This is a polynomial.
It is a binomial.
Hence four of the expressions shown are polynomials.

Leah combines 6.54 ounces of strawberries with 6.09 ounces of blueberries to make fruit bowls. She pours the fruit equally into 3 bowls, and has 1.68 ounces of fruit left over. How many ounces of fruit are in each bowl?
Answer:
4.21 Ounces
Step-by-step explanation:
You first want to add 6.54 to 6.09 getting you an answer of 12.63 then you want to divide that by 3 which gets you an answer of: there are 4.21 ounces in each bowl.
Lowest temps, Ontario, CA, April 2020 Date Low temperature 4/4/20 −1.8 °C 4/12/20 0.6 °C 4/18/20 −2.8 °C 4/23/20 (missing) 4/28/20 −0.2 °C The table shows the lowest temperatures recorded on five days in April 2020, but the value for 4/23/20 has been lost. If X is the lost value, and if we know that X was the middle value of the five days, which choice could be the value of X? A) −1.9 °C B) −0.9 °C C) −0.1 °C D) 0.4 °C
Answer: D
Step-by-step explanation:
If you notice there is a pattern going on here the first temp recorded is negetive then the next is a normal temp then the next is negetive so it would be reasonable to think that the next temp would be normal and all the other options are negetive exept for one which is D so the answer is D.
