Lines m and n are parallel Line m is described by the equation y = 40 +2. Line n contains the point (1, -3). Which of the follow
strojnjashka [21]

Answer:

B)Oy+ 3 = 4(x - 1)

Equation of the straight line   y +3 = 4( x-1)

Step-by-step explanation:

<u><em>Explanation:-</em></u>

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

Given that the equation   y = 4x +2

and given that the point (1,-3)

The equation of the parallel line to the given line

                       ax +by +k=0

                       4x-y +k=0

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

                  ⇒ 4(1) -(-3) +k=0

                  ⇒   4+3 +k=0

                          7 +k=0

                             k =-7

The equation of the Parallel line  4x-y -7 = 0

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

Given that the slope m = 4 and the point (1,-3)

Equation of the straight line

             y - y₁ = m(x-x₁)

             y -(-3) = 4( x-1)

            y +3 = 4( x-1)

Ahmad just bought a used sailboat with two sails that need replacing. How much sail fabric will Ahmad need if he replaces sail A
ValentinkaMS [17]

Answer:

sail a = 81ft²

sail b base = 12ft

Step-by-step explanation:

question 5:

the measurements for sail A are 18ft(height) and 9ft (base)

the formula to find the the area of a triangle is (b · h) 1/2

(9 · 18) 1/2 = (162) 1/2 = 81

so ahmad will need 81ft² of fabric for sail a

question 6:

we know that the formula to find the area of a triangle is  (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.  

(b · 18) 1/2 = 108

\frac{(b . 18) 1/2}{1/2} = 108/ 1/2

(b · 18) = 216

18b  = 216

18b/18 = 216/18

b= 12

check your work:

(12 · 18) 1/2 = 108

(216) 1/2 = 108

108 = 108  true!

the base measurement for sail b is 12ft

hope this helps and have a great day!!
