Is line 1 (1,5) (3,-2) and like 2 (-3,2) (4,0) perpendicular of parallel?

Lera25 [3.4K]

Slope Formula: $\frac{y_2-y_1}{x_2-x_1}$

So remember that <u>perpendicular lines have slopes that are negative reciprocals to each other</u> and <u>parallel lines have the same slope.</u> To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:

$\textsf{Line 1}\\\\\frac{5-(-2)}{1-3}=-\frac{7}{2}\\\\\textsf{Line 2}\\\\\frac{0-2}{4-(-3)}=-\frac{2}{7}$

Since these slopes aren't the same nor are they negative reciprocals to each other, <u>the lines are neither parallel nor perpendicular.</u>

Solve the equation or formula for the indicated variable.

8090 [49]

Answer:

h = $\frac{T - 2\pi r^{2}}{2\pi r}$

<u>Step-by-step explanation:</u>

T= 2rπh + 2πr²

Subtract terms that don't include the indicated variable from both sides:

T= 2rπh + 2πr² ⇒ T - 2πr² = 2rπh

Divide values being multiplied by indicated variable from both sides:

T - 2πr² = 2rπh ⇒ $\frac{T - 2\pi r^{2}}{2\pi r}$ = h
