When the coefficient in front of the x^2 term is 1 you can factor a quadratic by finding two numbers such that the sum is the coefficient infront of x and the product is c. So
a+b=-4 and ab=-5 notice that -5 and 1 are solutions since (-5)*1=-5 and 1-5=-4 so you can factor it as (x-5)(x+1).

<u>Trigonometry</u>

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is a leg
  • b is another leg
  • c is the hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Identify</u>

Leg <em>a</em> = 7.5

Leg <em>b</em> = 10

Hypotenuse <em>c</em> = <em>c</em>

<em />

<u>Step 2: Solve for </u><em><u>c</u></em>

  1. Substitute in variables [Pythagorean Theorem]:                                              7.5² + 10² = c²
  2. Rewrite:                                                                                                             c² = 7.5² + 10²
  3. Evaluate exponents:                                                                                         c² = 56.25 + 100
  4. Add:                                                                                                                   c² = 156.25
  5. [Equality Property] Square root both sides:                                                    c = 12.5

Establish which of the following statements are true. (a) A sequence is convergent if and only if all of its subsequences are co
yawa3891 [41]

Answer:

Statement A - True.

Statement B - False.

Statement C - True.

Statement D - False.

Step-by-step explanation:

(a) A sequence is convergent if and only if all of its subsequences are convergent - this statement is correct.

(b) A sequence is bounded if and only if all of its subsequences are bounded - this statement is incorrect.

(c) A sequence is monotonic if and only if all of its subsequences are monotonic - this statement is correct.

(d) A sequence is divergent if and only if all of its subsequences are divergent - this statement is incorrect.

Which function could be a stretch of the exponential decay function shown on the graph?
Ainat [17]

The function that could be a stretch of the exponential decay function shown on the graph is B. f(x) = One-half(6)x.

<h3>How to illustrate the function?</h3>

From the information given, it can be seen that function A is a monotonically increasing function.

Also, it can be seen that C and D don't pass through (0, 1).

Therefore, the function could be a stretch of the exponential decay function shown on the graph is B.
