Normal form [see attachment]

Mathematics

musickatia [10]3 years ago
4 0

I just did one of these. I guessed that normal form is


x \cos \phi + y \sin \phi -  p = 0


Here' that's


x (\sqrt{3}/2) + y (1/2) - 10 = 0


\sqrt{3} x + y - 20 = 0


Choice b

Joseph needed $125 to buy a new pair of jordan's. His neighbor will pay him $6 per hour to walk his dog and his mother gave him
AveGali [126]

Answer: 14⅝ hiurs

Step-by-step explanation:

Based on the information given in the question, we can form an equation which will be:

8 + 6h = 125

where, h = number of hours

6h = 125 - 8

6h = 117

h = 117/8

h = 14 ⅝hours

Therefore, minimum amount of hours he will need to walk the dog in order for him to buy a new pair of Jordans is 14⅝ hours.

Solve for x. Show the equation you used and your work.
levacccp [35]
The value of X is 27.

To solve this problem, you have to write a proportion with the given information. This can be done because the sides on the left and right are proportional with the values on the bottom.

36 / 24 = x / 18
x = 27

2x^{2} +4x+1=0 <br> Solve for x.
Viefleur [7K]
2x^2 + 4x + 1 = 0

2x^2 + 4x + 1 - 1 = 0 - 1

2x^2 + 4x = -1

X(2x + 4) = -1

X = -1.

2x + 4 = -1
2x + 4 - 4 = -1 - 4
2x = -5
2x/2 = -5/2
X = -5/2.

I believe these are the solutions. If not you can use the quadratic formula to solve for the roots, solutions.
