By applying the law of sines, the length of side PQ is equal to 7.1 units.

<h3>What is the law of sines?</h3>

The law of sines is also referred to as sine law and it can be defined as an equation that relates the side lengths of a triangle to the sines of its angles.

<h3>How to calculate the length of PQ?</h3>

Mathematically, the law of sines is given by this equation:

\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}

Substituting the given parameters into the formula, we have;

\frac{sin80}{PQ} =\frac{sin42}{4.8} \\\\\frac{0.9848}{PQ} =\frac{0.6691}{4.8}\\\\0.6691PQ = 4.7270\\\\PQ = 4.7270/0.6691

PQ = 7.1 units.

What is the area of the parallelogram represented by the vertices A(-6, -1), B(-2, -1), C(-1, -4) and D(-5, -4)?
kramer

Answer: 12 units²

Step-by-step explanation:

To find the area of a parallelogram, we use the formula A=l×w. To find the length and width, let's graph out the parallelogram to get a better view. Let's refer to the picture attached to see what the graph looks like. The length is 4 units while the width is 3 units. Therefore we multiply.

A=4×3=12 units²

Now, we know the area is 12 units².

Algebra help please?
spin [16.1K]

Answer is 3 seconds


When the bullet reaches the ground, ground being x in graph (and here its s which is  = 0)

s = -16t^2 + 48t

s = 0, solve for t

0 = -16t^2 + 48t

0 = t ( -16t + 48)

0 = 16t ( - t + 3)

now you have two equation

0 = 16t and 0 = -t +3 ( you can look at the graph line touches x twice)


0 = 16 t

0 = t ( you know its false, because time = 0)


You are left with

0 = -t + 3

t = 3


It takes 3 seconds for the bullet to return to the ground.

// Hope this helps.

The system of equations is solved using the linear combination method.
Alborosie

The interpretation of 0 = -12 is (a) There are no solutions to the system because the equations represent parallel lines.

<h3>How to interpret the result?</h3>

The result is given as:

0 = -12

By comparison 0 and -12 do not have the same value

i.e. 0 ≠ - 12

This means that the system of equation has no solution

Hence, the interpretation of 0 = -12 is (a)
