Answer:
The simplified sum of these polynomials is 3x^4y - 2xy^5
Step-by-step explanation:
In order to find this, we need to remember that we can only add together like terms in this case, there are only two like terms. Both of the first terms end in x^2y^2. So, we add these two together.
3x^2y^2 - 3x^2y^2 = 0
Since they cancel out, we simply just put the other two terms as our answer.
3x^4y - 2xy^5
Answer:
r = 8
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
16 pi = 2 * pi r
Divide each side by 2 pi
16 pi /2 pi = 2 pi r / 2 pi
8 = r

Answer:
cos L = 55/73
Step-by-step explanation:
The triangle KLM is a right angle triangle. The ∠M = 90°. The side KM = 48, LK = 73, and ML = 55. The ratio that represents the cosine of ∠L can be solved below.
The right angle triangle formed has an hypotenuse , opposite and an adjacent side. Using the SOHCAHTOA principle one can find the ratio that represent the cosine of ∠L.
opposite side = 48
adjacent = 55
hypotenuse = 73
cos L = adjacent/hypotenuse
cos L = 55/73
