Remove parameter y=bsintheta x=bsectheta
lesya [120]
\bf \begin{cases}
y=bsin(\theta)\\\\
x=bsec(\theta)\implies \frac{x}{sec(\theta)}=\boxed{b}\\
----------\\
y=\boxed{\frac{x}{sec(\theta)}}sin(\theta)
\end{cases}
\\\\\\
\textit{and you can simplify it further if you want}
\\\\\\

y=\cfrac{xsin(\theta)}{\frac{1}{cos(\theta)}}\implies y=\cfrac{xsin(\theta)}{1}\cdot \cfrac{cos(\theta)}{1}\implies y=xsin(\theta)cos(\theta)

Need help solveing this for class!
Mandarinka [93]

According to <em>graphical</em> and <em>analytical</em> methods, the value of the <em>input</em> variable associated with point of intersection between f(x) and g(x) is 1.5. (Correct choice: C)

<h3>How to determine the point of interception between two linear functions</h3>

<em>Linear</em> functions are polynomials with a grade of 1 and described by the following form:

y = m · x + b     (1)

Where:

  • x - Independent variable
  • m - Slope
  • y - Dependent variable
  • b - Intercept

Please notice that <em>horizontal</em> lines have a slope of 0.

There are two forms to estimate the coordinates of the point of intersection of the two functions: (i) <em>graphical</em>, (ii) <em>analytical</em>. According to the first method, the value of the <em>input</em> variable is approximately 1.5.

And according to the second method, we have the functions f(x) = 1 and g(x) = (4/3) · x - 1. Then, we must solve the following formula to determine the input variable of the point of interception:

1 = (4/3) · x - 1

(1/3) · x = 1/2

x = 3/2

x = 1.5

The value of the <em>input</em> variable is approximately 1.5.

According to <em>graphical</em> and <em>analytical</em> methods, the value of the <em>input</em> variable associated with point of intersection between f(x) and g(x) is 1.5. (Correct choice: C)

Alexander found the means-to-MAD ratio of two data sets to be 2.1.
horsena [70]
Okay, So We Need To First Remember The Rule About Means-To-Mad Ratios. It Is :
"You can use the means-to-MAD ratio to describe the similarity of two distributions. Divide the positive difference in the means by the larger of the two MAD values. If this ratio is 1 or less, the two distributions are similar. If this ratio is between 1 and 2.5, the two distributions are somewhat similar. If this ratio is greater than 2.5, the two distributions are different. "
So, Lets Use This Info. 2.1 Is Greater Than 1, So They Are Not Similar. It Is Greater Than 1 But Less Than 2.5, So, They Are Somewhat Similar. 2.1 Is Less Than 2.5, So They Are Not Different. They Cant Be Identical, Because That Would Mean It Is 0.  So, This Means That The Answer Is They Are Somewhat Similar. I Hope This Helps!
