Answer:
The Pythagorean theorem states that a2 + b2 = c2 in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two.

Answer:
y = 4x +3
Step-by-step explanation:
The slope formula can be used to find the slope:
m = (y2 -y1)/(x2 -x1)
Using the first two lines of the table, we find the slope to be ...
m = (11 -7)/(2 -1) = 4/1 = 4
__
The y-intercept can be found from the relation ...
b = y -mx
Using the slope we found, and the first line of the table, we find the intercept to be ...
b = 7 -4(1) = 3
__
Then the equation is ...
y = mx +b . . . . . . slope-intercept form of the equation for a line
y = 4x +3
Actual cost of the TV = $175.95
Percentage of discount given on the TV = 20%
Then
Amount of discount on the TV = (20/100) * 175.95 dollars
= 175.95/5 dollars
= 35.19 dollars
So cost of the TV after discount = (175.95 - 35.19) dollars
= 140.76 dollars
Now
Percentage of sales tax that needs to be added = 6%
Then
Amount of sales tax that needs to be added = (6/100) * 140.76 dollars
= 844.56/100 dollars
= 8.45 dollars
Then
Price of TV after adding sales tax = (140.76 + 8.45) dollars
= 149.21 dollars
So the cost of the TV after deducting the discount and adding the sales tax is $149.21
Let us assume then that the center is the origin. If the major axis is 18, then a = 9 and a^2=81. If the minor axis is 16, then b = 8 and b^2=64. Now you can write the equation. Remember that this ellipse is vertical and so a^2 goes under y^2
