What is the length of the major axis of the ellipse (x-7)^2/4+(y+3)^2/16=1
yuradex [85]
\bf \begin{array}{llll}
\cfrac{(x-{{ h}})^2}{{{ a}}^2}+\cfrac{(y-{{ k}})^2}{{{ b}}^2}=1\\\\ \cfrac{(x-{{ h}})^2}{{{ b}}^2}+\cfrac{(y-{{ k}})^2}{{{ a}}^2}=1
\end{array}\quad 
\begin{cases}
\textit{major axis}=a+a\\
a=\textit{the larger denominator}\\
b=\textit{smaller denominator}
\end{cases}\\\\
-----------------------------\\\\
\cfrac{(x-7)^2}{4}+\cfrac{(y+3)^2}{16}=1\implies \cfrac{(x-7)^2}{2^2}+\cfrac{(y+3)^2}{4^2}=1\quad 
\begin{cases}
a=4\\
b=2
\end{cases}

How to find the diameter of a circle with the area of 1134.1?
Alex17521 [72]
Radius is half of the diameter.
So because the area of a circle is A= pi • r^2, to find the radius first, we have to change the equation to solve for r. Now it is, r= square root of A/pi. We plug in 1134.1. (Look at pic)
The diameter is 38

Sharif likes exersicing.He goes hill-climbing every 12 days anf goes swimming every 8 days.If je goes hill-climbing and swimming
topjm [15]
This is a lowest common multiple question.
to find the lowest common multiple, you need to find the prime factors of the two numbers:
8 = 2 , 2 , 2
12 = 2 , 2 , 3
Take out duplicates:
2,2,2,3
and multiply them together:
2*2*2*3 = 24
and that is your answer.
Easy peasy.
