Can you please solve this I don't understand perpendicular lines

Mathematics

stira [4]3 years ago

Answer:

The equation of the perpendicular line 't' is  3x+y =0

Point slope form y = mx +C

                            y = - 3x

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given equation  s = \frac{1}{3}x +10    and given point (1,-3)

The equation of the perpendicular line

                        y =\frac{x+30}{3}

                 ⇒  3 y = x+30

               ⇒ x - 3y +30 =0

<u><em>Step(ii):-</em></u>

<em>The perpendicular line of the given straight line 's'</em>

<em>        b x -ay +k=0</em>

⇒  -3x -y +k=0

This line is passing through the point (1,-3)

     -3(1)-(-3)+k=0

            k =0

The equation of the perpendicular line   -3x-y =0

<u><em>Final answer:-</em></u>

The equation of the perpendicular line   3x+y =0

Point slope form y = mx +C

                            y = - 3x

Evaluate f(x) = -4x + x2 + 16 for f(-4).​
kipiarov [429]

Answer:

f(-4)=48

Step-by-step explanation:

<u>Value of functions</u>

To evaluate a function for a given value of x, we replace the x for the value and perform the resulting operations.

The given function is (corrected):

f(x)=-4x+x^2+16

We need to find f(-4), so we use x=-4:

f(-4)=-4*(-4)+(-4)^2+16

f(-4)=16+16+16

\boxed{f(-4)=48}

1/3 + a + 5/4. what is A
USPshnik [31]

Answer:

a = -1.58

Step-by-step explanation:

1/3 +a+5/4 =0

1/3+5/4= -a

4+15/12 = -a

19/12 = -a

1.58= -a

1.58/-1 = -a/-1

-1.58 = a

The cosine law

\bf \textit{Law of sines}&#10;\\ \quad \\&#10;\cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c}\\\\&#10;-------------------------------\\\\

\bf \cfrac{sin(88^o)}{39.9}=\cfrac{sin(A)}{31}\implies \cfrac{31\cdot  sin(88^o)}{39.9}=sin(A)&#10;\\\\\\&#10;sin^{-1}\left[ \cfrac{31\cdot  sin(88^o)}{39.9} \right]=sin^{-1}\left[ sin(A) \right]&#10;\\\\\\&#10;sin^{-1}\left[ \cfrac{31\cdot  sin(88^o)}{39.9} \right]=\measuredangle A&#10;\\\\\\&#10;50.93841^o\approx \measuredangle A\qquad thus\qquad \measuredangle C\approx 41.0619^o
