Domain: (-∞,∞)

Range: (3,∞)

x-intercepts: none

y-intercepts: (0,7)

Interval positive: (3,∞)

Interval negative: none

Interval increasing: (7,∞)

Q4: Write the equation in slope-intercept form of the line that is perpendicular to

forsale [732]

Answer:

5y = x + 11

Step-by-step explanation:

Given parameters:

Equation of the line ;

y = -5x + 1

Coordinates = (2, -1)

Find the equation of a line perpendicular;

Solution:

A line perpendicular to y = -5x + 1 will have slope that is a negative inverse of the given one.

Equation of a straight line is expressed as;

y = mx + c

y and x are the coordinates

m is the slope

c is the y-intercept

So, the slope of the new line perpendicular is $\frac{1}{5}$ ;

Now let us find the y-intercept of the new line;

x = -1 and y = 2

2 = $\frac{1}{5}$ x (-1) + c

c = 2 + $\frac{1}{5}$ = $\frac{11}{5}$

The equation of the new line is;

y = $\frac{1}{5}$ x + $\frac{11}{5}$

or multiply through by 5;

5y = x + 11

Step-by-step explanation:

$\sin^2 (\frac{\pi}{4} - \alpha) = \frac{1}{2}(1 - \sin 2\alpha)$

Use the identity

$\sin^2 \theta = \dfrac{1 - \cos 2\theta}{2}$

on the left side.

$\dfrac{1 - \cos [2(\frac{\pi}{4} - \alpha)]}{2} = \frac{1}{2}(1 - \sin 2\alpha)$

$\dfrac{1 - \cos (\frac{\pi}{2} - 2\alpha)}{2} = \frac{1}{2}(1 - \sin 2\alpha)$

Now use the identity

$\sin \theta = \cos(\frac{\pi}{2} - \theta)$

on the left side.

$\dfrac{1 - \sin 2\alpha}{2} = \frac{1}{2}(1 - \sin 2\alpha)$

$\frac{1}{2}(1 - \sin 2\alpha) = \frac{1}{2}(1 - \sin 2\alpha)$
