What is the point -slope form of a line with slope -4 that contains the point (-2,3)

Arada [10]

Answer:

y - 3 = -4 (x +2)

Step-by-step explanation:

Point slope form is

y -y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line

y - 3 = -4 (x - -2)

y - 3 = -4 (x +2)

The points A(-3, 2) and B(1,4) are vertices of an isosceles triangle ABC, where angle B = 90°

almond37 [142]

Answer:

Length of AB = 4.4721

Equation of line BC: y = -2x + 6

Step-by-step explanation:

To find the length of the line AB, we just need to find the distance between the points A and B.

We can find distance with the equation:

$distance = \sqrt{(x_A - x_B)^2 + (y_A - y_B)^2}$

$distance = \sqrt{(-3 - 1)^2 + (2 - 4)^2}$

$distance = 4.4721$

To find the equation of the line BC, first let's find the slope of the line AB.

This slope is given by:

$m_{AB} = \frac{ y_A - y_B }{ x_A - x_B }$

$m_{AB} = \frac{ 2 - 4 }{ -3 - 1} = \frac{1}{2}$

The line AB is perpendicular to the line BC (because mB = 90°), so the slope of line BC is:

$m_{BC} = -\frac{1}{m_{AB}} = -2$

so the line BC is:

$y = -2x + b$

To find the value of b, we can use the point B (1,4):

$4 = -2 + b$

$b = 6$

So we have:

$y = -2x + 6$

Solve the trigonometric equation 3-3cosx=2 sin^2 x

Zina [86]

= 3 - 3cos x - 2(1- cos^2 x)
= 2cos^2 x - 3cos x + 1
=(cos x -1)(cosx - 1/2)
now cos x = 1 or cos x= 1/2
draw a graph we get = + ve values
hence .. 0 ,180,360 and 60,240, degrees in range x<2pi
