92 x 68 = 6,256 to estimate you can say 6,300
Answer:
theres no scatter plot
Step-by-step explanation:
Answer: a) + = 1
b) The distance of two foci is 85.4 feet
c) Area = 3502.67 square feet
Step-by-step explanation: a) An ellipse has the equation in the form of:
+ = 1, where a is the horizontal axis and b is the vertical axis.
For the Statuary Hall, a = = 48.5 and b = = 23, so the equation will be
+ = 1.
b) To determine the distance of the foci, we have to calculate 2c, where c is the distance between one focus and the center of the ellipse. To find c, as a, b and c create a triangle with a as hypotenuse:
=
c =
c = 42.7
The distance is 2c, so 2·42.7 = 85.4 feet.
The two foci are 85.4 feet apart.
c)The area of an ellipse is given by:
A = a.b.π
A = 48.5 · 23 · 3.14
A = 3502.67 ft²
The area of the floor room is 3502.67ft².
Answer:
Step-by-step explanation:
1). 6x + 7 - 18x + 4
= (6x - 18x) + (7 + 4)
= -12x + 11
2). 5x - 7x + 5x + 4 - 9
= (5x + 5x - 7x) + (4 - 9)
= 3x - 5
3). 3x + 8y - 5x + 3y
= (3x - 5x) + (8y + 3y)
= -2x + 11y
4). 17x² - 7x²- 5x + 3x + 14
= (17x² - 7x²) + (-5x + 3x) + 14
= 10x² - 2x + 14
5). 3xy - 9xy - 5x + 4x - 7 + 3
= (3xy - 9xy) + (-5x + 4x) + (-7 + 3)
= -6xy - x - 4
6). 9x + 7y - 15x + 4x - 9y
= (9x - 15x + 4x) + (7y - 9y)
= -2x - 2y
7). 3x + 7 - 5x - 8y + 4x - 2y + 7
= (3x - 5x + 4x) + (-8y - 2y) + 14
= 2x - 10y + 14
8). 3xy - xy + 15x + 4 - 11
= (3xy - xy) + 15x + (4 - 11)
= 2xy + 15x - 7
9). -8x + 3x + 7y - 5x + 4y - 2
= (-8x - 5x + 3x) + (7y + 4y) - 2
= -10x + 11y - 2
10). 3x² + 6x - 3y + 2x - 7
= 3x² + (6x + 2x) - 3y - 7
= 3x² + 8x - 3y - 7
Answer:
29.50
Step-by-step explanation:
Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.
