Answer:
The equation of a vertical ellipse is
Step-by-step explanation:
Here, given:
Length of major axis: 20
⇒ 2 a = 20 , or , a = 10
Length of minor axis: 12
⇒ 2 b = 12 , or , b = 6
Also, center (h,k) = (6,3)
Now, STANDARD EQUATION OF ELLIPSE :
Now, substituting the values, a, b , h and k in above expression, we get:
or,
Hence, the equation of a vertical ellipse is
Answer:
15x + 14y = -218
Step-by-step explanation:
To write the equation of a line when given two points, calculate the slope and substitute it into the point slope form of a line. From this form of the equation, you can simplify and convert to the standard form.
First, find the slope using the formula.
Substitute m = -15/14 and the point (-8,6) into the point slope form .
To convert to standard form, multiply the equation by 14. This means each term is multiplied by 14 to clear the denominator. Then multiply using the distributive property. You will now need to move terms across the equal sign. Begin by adding 15x to both sides. Lastly, subtract 98 from both side.

Step-by-step explanation:
<h2>
Answer:</h2>
The ratios of earnings to hours are not the same each week, so the earnings do not vary directly with the hours.
<h2>
Step-by-step explanation:</h2>
We know that the data points given by (x,y) are in direct variation if:
for each (x,y)
We are given data as:
Caleb’s Earnings Hours(x) 12 15 18 21
Earnings (in dollars)(y) 140 170 200 230
So, we could see the ratio as:
Hence, we could see that each ratio are not equal.
Hence, the relationship between the earnings and the number of hours does not represents a direct variation.
