riadik2000 [5.3K]2 years ago
5 0

Answer:

Step-by-step explanation:

18.

slope of line y=2x-5 is 2

slope of line ⊥ to y=2x-5 is

m=-1/2

eq. of reqd. line through (10,6) with slope -1/2 is

y-6=-1/2(x-10)

multiply by 2

2y-12=-x+10

2y+x=10+12

2y+x=22

2y=-x+22

y=-1/2x+11

19.

slope of line y=12x+5,m=12

eq. of line through (5,2) with slope 12 is

y-2=12(x-5)

y-2=12x-60

y=12x-60+2

y=12x-58

compare with y=mx+b

b=-58

Use Lagrange multipliers to solve the following exercise. A home improvement contractor is painting the walls and ceiling of a r
mash [69]

Answer:

Let the width of the garden =x meter

Then length=(x+4) meter

Half perimeter =36 m

So perimeter of garden =(2×36)=72 meters

According to the question

⇒2(l+b)=72

⇒2(x+x+4)=72

⇒2x+2x+4=74⇒4x=64⇒x=16 meters

Hence,the width of the garden =16 meters

The length of the garden =(16+4)=20 meters

The parent function of the function g(x) = (x - 5)2 + k is f(x) = x2. The vertex of the function g(x) is located at (9,-8).
likoan [24]

Answer:

h = 5 and k = -8.

Step-by-step explanation:

The parent equation is f(x) = x², which is the equation of a parabola having the vertex at point (0,0).

The original equation is given by g(x) = (x - 5)² + k, ⇒ y = (x - 5)² + k

⇒ y - k = (x - 5)²

So, the vertex of the original equation is at (5, k) which is given to be (5, -8)

Therefore, h = 5 and k = -8. (Answer)
