Write the equation of an ellipse with the following characteristics: center =(1,-3) vertices=(-6,-3),(8,-3)
Foci =(-4.7,-3),(6.7,-3)
Answers
Answer:
(x-1)²/49 + (y+3)²/16.51 = 1
Step-by-step explanation:
vertex (8,-3) Foci (6.7,-3) center (h,k) = (1,-3) , major axis parallel to x axis
a is the distance of the vertex from the center, and c is the distance of the foci from the center. b is semi-minor axis
b² = a² - c² Ellipse equation: (x-h)²/a² + (y-k)²/b² = 1
a = 8-1 = 7 c = 6.7 - 1 = 5.7
b² = 7² - 5.7² = 16.51
Ellipse equation: (x-1)²/49 + (y- -3)²/16.51 = 1 i.e. (x-1)²/49 + (y+3)²/16.51 = 1

The equations y = 7x – 2 and 14x – 2y = 3 represent
(A) parallel lines
(B) perpendicular lines
(C) the same line
(D) intersecting, non-perpendicular lines
Answers
Answer:
Parallel lines
Step-by-step explanation:
The standard form of equation of a straight line is expressed as:
y = MX+c
m is the slope
Given the equations
y = 7x – 2
On comparison;
m = 7 i.e the slope of the line is 7
For the line 14x – 2y = 3
First write in standard form
-2y = -14x +3
y = -14x/-2 + 3/-2
y = 7x- 3/2
Hence the slope is also 7
Since both equations have the same slope hence they are parallel lines(Parallel lines have the same slope)

7/2 and 3
Step-by-step explanation:
using quadratic formula
{-(-13) +- √(-13)^2 - 4(2)(21) } /2(2)
-(-13)+1 / 4 = 7/2
-(-13)-1 / 4 = 3
Answer: x = 7/2 and 3
Step-by-step explanation: Rewrite and factor
2x² —13x + 21 = 0
(2x - 7)(x - 3) = 0
2x - 7 = 0. x = 7/2
x - 3 = 0 x = 3

A city has a 5% sales tax.
A book costs $32.55 after tax.
How much did it cost before tax?
*please answer quick and tell me how you did it*
Answers
Answer: $30.92
Step-by-step explanation:
First step is to turn 5% into a decimal so that you can use it easier in a math sentence -- 0.05
Next, find out what 5% of $32.55 is by multiplying
0.05 x 32.55
= 1.6275
Round to the nearest cent because we don't use anything smaller than a cent when we are talking about money.
= $1.63
This is the amount of tax included in the price of $32.55
If we want to know what it the book cost before tax we simply take the tax off.
$32.55 - $1.63
= $30.92
Hope that helps :)
