Answer:

=25a6−36a4

Step-by-step explanation:

=(5a3+−6a2)(5a3+6a2)

=(5a3)(5a3)+(5a3)(6a2)+(−6a2)(5a3)+(−6a2)(6a2)

=25a6+30a5−30a5−36a4

=25a6−36a4

HELPPP!! <br> Triangle ABC is similar to triangle MOP. A = 45 and P = 102. What is the measure of B?
erma4kov [3.2K]

Answer:

       \large\boxed{\large\boxed{33\º}}

Explanation:

The order of the letters naming the triangles is relevant. When it is said that <em>triangle ABC is similar to triangle MOP</em>, means that:

  • ∡A ≅ ∡M
  • ∡B ≅ ∡O
  • ∡C ≅ ∡P

Therefore:

  • ∡A = 45º (given)
  • ∡P = 102º (given)
  • ∡C = 102º (by substitution)

Now, you have two angles of triangle ABC and can find the third one:

  • ∡A + ∡B + ∡C = 180º
  • ∡B = 180º - ∡A - ∡B
  • ∡B = 180º - 45º - 102º = 33º ← answer

K here’s another one please help
Luden [163]

Answer:

Both the relations are functions, the correct answer is a.

Step-by-step explanation:

In order to solve this problem we will first find the inverse relation as shown below:

y = 3x^2 + 5\\x = 3y^2 + 5\\3y^2 = x - 5\\y^2 = \frac{x - 5}{3}\\y = \sqrt{\frac{x - 5}{3}} = \frac{\sqrt{x - 5}}{\sqrt{3}}\\y = \frac{\sqrt{x - 5}\sqrt{3}}{\sqrt{3}\sqrt{3}} = \frac{\sqrt{3x - 15}}{3}

Functions are relations between two groups of numbers, for which the input must generate only one output. Using this definition we can classify both the relation and its inverse as a function, therefore the correct answer is a.
