A line is perpendicular to y = -x + 1

frozen [14]

Answer: The equation of the perpendicular line intersects the point (-5,1) is y=x+6[/tex]

Step-by-step explanation:

step1:-

The standard form of slope - intercept form y=m x+c

Here m is called slope of the given line

C is called the y- intercept of the given line

Given equation of the straight line y=-x+1

comparing the slope - intercept form y=m x+c

here m= -1 and c=1

step2:-

The equation of the perpendicular line is

$y-{[y_{1}$ } =\frac{-1}{m} (x-x_{1} )[/tex]

substitute m = -1 and c =1 values in equation

$y-1 =\frac{-1}{-1} (x-(-5 )$

$y-1 ={1} (x-(-5 )$

$y=1+x+5\\y=x+6$

step3:- The equation of the perpendicular line intersects the point (-5,1) is

y=x+6[/tex]

<u>conclusion</u><u>:</u>-

The equation of the perpendicular line is

y=x+6[/tex]

Expand and simplify 2(5x+3)−2(x 2 −3) =10x+6−(2(x 2 −3))= =10x+6−(2x 2 −6)= =10x+6−2x 2 +6= =−2x 2 +10x+12

gulaghasi [49]

Answer:

-2x² + 10x - 12

Step-by-step explanation:

Given the expression 2(5x+3)−2(x^2 −3)

Expand

2(5x+3)−2(x^2 −3)

= 2(5x)+2(3) -2(x²)-2(-3)

= 10x + 6 - 2x²+6

= 10x -2x²+12

Express in standard form

= -2x² + 10x - 12

Enter the amplitude of the function f(x) . f(x)=3/4cos(3x)+4

Alisiya [41]

Answer:

The amplitude is $\frac{3}{4}$

Step-by-step explanation:

Let f(x) be a sinusoid function that has the following format:

$f(x) = bsin(wx + s) + h$

Then b is the amplitude of the function

h is the vertical displacement of the wave

s is the phase angle

$\frac{2\pi}{w}$ is the period.

In this problem $f (x) = \frac{3}{4}cos(3x) +4$

Then $\frac{3}{4} = b$

Therefore the amplitude of the function is $\frac{3}{4}$

The amplitude is a measure of the vertical size of the sinx wave
