Answer:

f(x) = 3x

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)

m = \frac{3-0}{1-0} = 3 , then

y = 3x ← is the equation of the graphed line

The perimeter of a rectangular swimming pool is 154m.Its length is 2m more than twice its breadth. What are the length and bread
TiliK225 [7]

P = 154\\a = 2b + 2

a = ?; b = ?

P = 2(a + b) = 2(2b + 2 + b) = 2(3b + 2) = 6b + 4

154 = 6b + 4\\6b = 154 - 4\\6b = 150\\b = 150 : 6\\b = 25

a = 2b + 2 = 2 * 25 + 2 = 50 + 2 = 52

Answer: 25 and 52 m.

Use the law of cosines to find the length of a
borishaifa [10]

Answer:

Step-by-step explanation:

You don't need the Law of Cosines, the Law of sines if what you need. You can't use the Law of Cosines because in order to find side a, you would need the length of side c and you don't have it. Using the Law of Sines is appropriate, knowing that angle B = 55:

\frac{sin55}{175}=\frac{sin42}{a} and solving for a:

a=\frac{175sin42}{sin55} so

a = 143.0
