Q4: Write the equation in slope-intercept form of the line that is perpendicular to
the graph of each equation and passes through the given point.
y = -5x + 1; (2, -1)

Answers

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 [tex]\frac{1}{5}[/tex] ;

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

   x = -1 and y = 2

      2  = [tex]\frac{1}{5}[/tex] x (-1) + c

           c  = 2 + [tex]\frac{1}{5}[/tex]   = [tex]\frac{11}{5}[/tex]  

The equation of the new line is;

          y  =  [tex]\frac{1}{5}[/tex]x +  [tex]\frac{11}{5}[/tex]  

or multiply through by 5;

        5y  = x + 11

4. If m3 = 54°, find the measure of each missing angle

Answers

Answer:Answer/Step-by-step explanation:

Given that m<3 = 54°

a. <1, <2, and <3 are angles on a straight line. They add up to 180°.

m<3 is given as 54°, m<2 = 90°, therefore,

m<1 = 180 - (54 + 90) = 180 - 144

m<1 = 36°

b. <2 is indicated as a right angle. Therefore, m<2 = 90°

c. <1 and <4 are vertical opposite angles. Vertical angles are congruent, since m<1 = 36°, therefore, m<4 = 36°

d. <5 and <2 are vertical opposite angles. m<2 = m<5, therefore, m<5 = 90°

e. <6 and <3 are vertical opposite angles. m<3 = m<6, therefore, m<6 = 54°

f. m<7 + m<6 = 180° (same side interior angles are supplementary)

m<7 = 180 - m<6

m<7 = 180 - 54

m<7 = 126°

g. m<7 + m<8 = 180° (linear pair)

126° + m<8 = 180

m<8 = 180 - 126

m<8 = 54°

h. m<9 = 180 - m<8 (linear pair)

m<9 = 180 - 54

m<9 = 126°

i. m<10 = m<8 (vertical angles)

m<10 = 54°

j. m<11 = m<4 (alternate interior angles are congruent)

m<11 = 36°

k. m<12 = 180 - m<11 (linear pair)

m<12 = 180 - 36

m<12 = 144°

l. m<13 = m<11 (vertical angles)

m<13 = 36°

m. m<14 = m<12 (vertical angles)

m<14 = 144°

Step-by-step explanation:

Answer:

A. M<1 = 36°

B. M<2= 90°

C. M<4= 36°

D. M<5= 54°

E. M<6= 54°

F. M<7= 126°

G. M<8= 54°

H. M<9= 126°

I. M<10 = 54°

J. M<11 = 36°

K. M<12 = 144°

L. M<13= 36°

M. M<14 = 144°

A rectangle has a perimeter of 32 in. Find the length and width of the rectangle under which the area is the largest.

a. Let the width to be x and the length to be y , then the quantity to be maximized is (expressed as a function of both x and y) A=_____
b. The condition that x and y must satisfy is y=______

Answers

Answer:

Length of the rectangle is 8 in and the breadth is 8 in.

a. [tex]A=xy[/tex]

b. [tex]y=16-x[/tex]

Step-by-step explanation:

Length = x

Breadth = y

Area is given by [tex]A=xy[/tex]

Perimeter of rectangle is given by

[tex]2(x+y)=32\\\Rightarrow x+y=16\\\Rightarrow y=16-x[/tex]

The condition that x and must satisfy is [tex]y=16-x[/tex]

So, area is

[tex]A(x)=x(16-x)\\\Rightarrow A(x)=16x-x^2[/tex]

Differentiating with respect to x we get

[tex]A'(x)=16-2x[/tex]

Equating with zero

[tex]0=16-2x\\\Rightarrow x=\dfrac{16}{2}\\\Rightarrow x=8[/tex]

Double derivative of A(x)

[tex]A''(x)=-2[/tex]

So [tex]A''(x)<0[/tex] which means [tex]A(x)[/tex] is maximum at [tex]x = 8[/tex]

[tex]y=16-x=16-8\\\Rightarrow y=8[/tex]

So length of the rectangle is 8 in and the breadth is 8 in.
