Answer:

Step-by-step explanation:

<em>Midpoint Formula:</em>

$\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}$

$\frac{3+1}{2}$ ⇒ $\frac{4}{2}$ ⇒ $2$

$\frac{8+-4}{2}$ ⇒ $\frac{8-4}{2}$ ⇒ $\frac{4}{2}$ ⇒ $2$

$(2,2)$

Answer:

see explanation

Step-by-step explanation:

The measure of arc MP = 360° - measure of arc PM, that is

arc MP = 360° - 210° = 150°

x is half the measure of the intercepted arc MP, thus

x = 0.5 × 150 = 75

Please help, with factoring

lora16 [44]

Using the FOIL Method (First, Outer, Inner, Last) of multiplying binomials, C would be formed by the last numbers multiplied, or the "last" portion of "FOIL."

Thus, multiplying P and Q would give you C, and the answer is A.

Answer:

The correct answer is "Option C".

Step-by-step explanation:

Given:

$\bold{ 1) y= -\tan (x- \frac{\pi}{2})}\\\\\bold{ 2) y= \tan (x+ \frac{\pi}{2})}\\\\\bold{ 3) y= -\cot (x- \frac{\pi}{2})}\\\\\bold{ 4) y= \cot (x+ \frac{\pi}{2})}\\\\$

solve the above equation:

$\Rightarrow 1) \ y= -\tan (x- \frac{\pi}{2})\\\\\Rightarrow \ y= \tan (\frac{\pi}{2}-x)\\\\\Rightarrow \ y= \cot x \ \ \ \ \ \bold{ that \ matchs \ graph \ D}\\\\ \Rightarrow 2) \ y= \tan (x+ \frac{\pi}{2})\\\\\Rightarrow \ y= - \cot x \ \ \ \ \bold{ that \ matchs \ graph \ A}\\\\$

$\Rightarrow 3) \ y= -\cot (x- \frac{\pi}{2})\\\\\Rightarrow \ y=\cot ( \frac{\pi}{2}-x)\\\\\Rightarrow \ y=\tan x\ \ \ \ \bold{that \ matchs \ graph \ C}\\\\$

$\Rightarrow 4) \ y= \cot (x+ \frac{\pi}{2})\\\\\Rightarrow \ y= \cot (\frac{\pi}{2}+x)\\\\\Rightarrow \ y= \ -tan x \ \ \ \ \ \bold{ that \ matchs \ graph \ A}$

The final answer is "Option C".
