kotykmax [81]

Answer:

A

Step-by-step explanation:

using the sine ratio in the right triangle, then

sin 45° = \frac{opposite}{hypotenuse} = \frac{x}{5}

multiply both sides by 5

note the exact value of sin 45° = \frac{\sqrt{2} }{2}

x = 5 × sin 45° = 5 × \frac{\sqrt{2} }{2} = \frac{5\sqrt{2} }{2}

Segment MN has endpoints at M(-5, 4) and N(7, -5). What is the midpoint of MN???? PLZ HELP
Paha777 [63]
Theres a formula to find the midpoint it’s... (x1+x2)/2, (y1+y2)/2. You fill in the x’s and y’s to get (-5+7)/2 for x, which equals 1 and (4-5)/2 to get -0.5. (1, -0.5) is your answer

Help would be much appreciated!​
Vlada [557]

Answer:

  • x = 5

Step-by-step explanation:

A hole is an input value that makes both numerator and denominator equal to zero.

In other words, same factor in both numerator and denominator.

<u>Let's factorize the denominator:</u>

  • x² - 7x + 10 = x² - 5x - 2x +  10 = x(x - 5) - 2(x - 5) = (x - 2)(x - 5)

<u>We have same factor of x - 5:</u>

  • x - 5 = 0
  • x = 5 is a hole
