Answer:
B - yes
Step-by-step explanation:
If (n - 9) is a factor then when evaluated at n = 9, if the result is zero then it is a factor of the polynomial, that is
9³ + 9² - 84(9) - 54
= 729 + 81 - 756 - 54
= 0
Since the result is zero then (n - 9) is a factor of the polynomial
Hello! I can help you with this!
A. Okay. So, to find the area of the square all you have to do is the number square, or multiply the number by itself, in this case. 3.5. 3.5^2 is 12.25. The area of the square is 12.25 square meters large.
B. To find the area of the circle, you do pi*r^2. Radius is half the the diameter. Half of 4 is 2. 2^2 is 4. To multiply by pi, we can just do it as 3.14. 4 * 3.14 is 12.56. The circle is 12.56 square meters large.
C. The circle garden would give her the most space to plant, because 12.56 is larger than 12.25 by 0.31. The circle garden 0.31 square meters larger than the square garden.
Answer:
I think its the 3rd option, im not sure.
Step-by-step explanation:
Use the angle difference formula for cosine.
cos(α − β) = cos α cos β + sin α sin β
cos(180° − θ) = cos 180° cos θ + sin 180° sin θ
cos(180° − θ) = (-1) cos θ + (0) sin θ
cos(180° − θ) = -cos θ
