Answer:
The graph is shown below.
Step-by-step explanation:
Take the distance above surface of water as positive and negative for below the surface.
Given:
Distance of dock from the surface of water, 
Distance of hook from the surface of water, 
The surface of water is the reference point and hence it has a value of 0.
Now, on a number line, the values to the left of 0 mark is negative and values to the right are positive.
Therefore, H will lie on the left of 0 mark and D will lie on the right as shown below.
Answer:
<h3>1kg</h3>
Step-by-step explanation:
According to Newton's second law
Force = mass * acceleration
Given
Force = 2N
acceleration = 2m/s^2
Mass =Force/Acceleration
Mass = 2/2
Mass =1kg
Hence the mass of the ball is 1kg
Answer:
See below.
Step-by-step explanation:
We know that the equation
is a true equation for a particular value of x.
Now, let's see what happens if we divide everything by 4. In other words:

Divide:

So, we get
.
When we divided everything by 4, we used the division property of equality. Under this property, the equation remains the same even if we divided since we did the <em>same thing to both sides of the equation. </em>
Therefore,
is also true for the same value of x because it is just a simplified version of
.
Answer=65 pairs of shoes
Given the data, the following equation can be made where x is equal to the number of shoes sent to the outlet mall.
845=4x+4x+4x+x
845=13x
divide both sides by 13
65=x
65 pairs of shoes were sent to the outlet mall
Answer:
1: x = -1
2: x = 3
3: x = -3
Step-by-step explanation:
f(x)=<u>x^3+x^2</u>−9x−9
f(x)=x^2<u>(</u>x+1) <u>−9x−9</u>
f(x) = x^2<u>(x+1)</u> - 9<u>(x+1)</u>
f(x)= (x+1)<u>(x^2-9)</u>
f(x) =(x+1)(x-3)(x+3)
