Answer:

\boxed{(b) \: y = 2x - 1}

Step-by-step explanation:

<h3>Find the gradient </h3>

( 2,3 ) and ( 0, -1)

m =   \frac{y2 - y1}{x2 - x1}  =  \frac{ - 1 - 3}{0 - 2}  =  \frac{ - 4}{ - 2}  = 2

Gradient is 2

<h3>Find linear equation</h3>

y - y1 = m ( x - x1 )

y - 3 = 2 ( x - 2 )

y - 3 = 2x - 4

y = 2x - 4 + 3

\boxed{y = 2x - 1}

Calculate the force exerted on the blown dart. A dart weighing 0.0056kg is blown and travels 4.85m. The change in velocity for t
dlinn [17]

Answer:

0.15N

Step-by-step explanation:

Given data

Mass= 0.0056kg

distance=  4.85m

Velocity= 11.4m/s

The expression for the force is

F= mv^2/r

substitute

F=  0.0056* 11.4^2/4.85

F=  0.0056*129.96/4.85

F= 0.727776/4.85

F= 0.15N

Hence the force is 0.15N

In the diagram, VZ/YZ=WZ/XZ. To prove that △VWZ ~ △YXZ by the SAS similarity theorem, which other sides or angles should be used
Vitek1552 [10]

Answer:

The angles \angle VZW\cong \angle YZX are used to prove the similarity of triangles VWZ and YXZ.

Step-by-step explanation:

Given information: \frac{VZ}{YZ}=\frac{WZ}{XZ}

Two triangles are called congruent if their corresponding sides are in same proportion or the corresponding angles are same.

If two corresponding sides of triangle have same proportion and their inclined angle is same, then by SAS rule of similarity both triangles are similar.

From the given figure it is noticed that the ∠VZW and ∠YZX are vertically opposite angles. The vertically opposite angles are always equal.

\angle VZW=\angle YZX                   (Vertically opposite angles)

\frac{VZ}{YZ}=\frac{WZ}{XZ}                (Given)

By SAS rule of similarity

VWZ\sim YXZ

Therefore the angles \angle VZW\cong \angle YZX are used to prove the similarity of triangles VWZ and YXZ.

F(x) = x2. What is g(x)?
ahrayia [7]

Answer:

Answer: g(x)=. Step-by-step explanation: We are given that: f(x)=x². We have to find g(x). Since, we are given that g(3)=1. Hence, we will ...  ·  g of x would equal (1/3x)^2 because if x was 6 y, g(x), would be 4
