Answer:
b) Circle
Step-by-step explanation:
<em>All</em> of the conic sections have vertices and foci. These features are not usually talked about for a circle, so perhaps "circle" is the expected answer.
__
A circle is a special case of ellipse with eccentricity 0. Its foci are coincident at its center, and its vertices are the ends of any pair of perpendicular diameters.
15 is equal to 15, 24 is greater than 15 and so is 32, so c, d, and e are correct
Answer:
Betty produced 613 gallons while Georgette produced 851 gallons
Step-by-step explanation:
Let Betty be X and Georgette be Y
The first equation
Y= 2x-375
Second equation
X+Y = 1464
This is simultaneous equation.
We are using substitution method
From equation 1 the value of Y= 2x-375
Substitute for the value of y in equation 2
X+Y= 1464
X + 2X - 375= 1464
Collect like terms
3x=1464+375
3x= 1839
X= 613
To get the value of Y
Substitute for Y in equation 1
Y= 2x - 375
Y= 2(613) - 375
Y= 1226 - 375
Y= 851
Since X= Betty and Y = Georgette
Betty produced 613 gallons while Georgette produced 851 gallons
Answer:
a = - 17
Step-by-step explanation:
5+2a = -29
2a = -29-5
2a = - 34
a = -34/2
a = -17
