Answer:
<u> -54.5%</u>
Step-by-step explanation:
You will have to use this formula

When substituted in you have 
30-66=-36
-36/66= -0.54 (54 repeating)
Then you have to convert this into a percentage, -54.54(repeating) percent
To the nearest hundredth you would round down to<u> -54.5%</u>.
It is a Decrease because it is negatated.
Answer:
The answer is:
Step-by-step explanation:
The equation of a parabola in the intercept form is given by:

Where:
p and q are x-intercepts
Now, we know the parabola intercepts at x=1 and x=3.
So we will have:

Using the point (-1,16) we could find the value of a.



Therefore, the equation is:



<u>The answer is: </u>
I hope it helps you!
<h2>Using the quadratic formula</h2>
The quadratic formula can help us solve for x in a quadratic equation:

We can use this when the given equation is organized in standard form: 
<h3>Applying this to the problem</h3>

First we can identify the values of a, b and c:
a = 2
b = 5
c = -4
Plug these values into the quadratic formula:




<h2>Answer</h2>
Therefore, the two possible values of x are:


Answer:
The minimum of the sinusoidal function is -4
Step-by-step explanation:
The given sinusoidal function has an amplitude of 4.
The range of the given sinusoidal function is
.
The minimum value is the least y-value of the range which is -4.
The minimum is therefore -4.
Answer:
Yvette plotted (10, 2) because for 10 oranges you have 2 pineapples. Similarly, she would plot (20, 4) for the same reason.
