Answer:

Step-by-step explanation:
An ellipse with vertices (-8, 0) and (8, 0)
Distance between two vertices = 2a
Distance between (-8,0) and (8,0) = 16
2a= 16
so a= 8
Vertex is (h+a,k)
we know a=8, so vertex is (h+8,k)
Now compare (h+8,k) with vertex (8,0) and find out h and k
h+8 =8, h=0
k =0
a minor axis of length 10.
Length of minor axis = 2b
2b = 10
so b = 5
General formula for the equation of horizontal ellipse is

a= 8 , b=5 , h=0,k=0. equation becomes


Answer: 52,416,000 km
Step-by-step explanation:
If a comet travels 273,000 km/hr
1) Multiply 273,000 km by 24 hours to find how far the comet travels in one day
2) multiply the answer from 1 by 8 to determine how far it travels in 8 days
1)
*
=
(hours cancel out)
2)
*8 day= 52,416,000 km in 8 days
The comet approximately travelled 52,416,000km from when it began to travel to when it reached Earth. Hope this helped :)
So she made 32 cups last year...she made 2 times as much this year...so she made 2(32) = 64 cups this year.
1 gallon = 16 cups
64/16 = 4 gallons
The answer is Chesa made 4 gallons of soup
The expression represented by 21 increased by twice Gail's height is 21 + 2g
<h3>What are expressions?</h3>
Expressions are mathematical statements that are represented by variables, coefficients and operators
<h3>How to translate the algebraic expression?</h3>
The expression is given as
21 increased by twice Gail's height
Where
g represents Gail's height
So, we have
21 increased by twice Gail's height ⇒ 21 increased by twice g
Twice means 2*
So, we have
21 increased by twice Gail's height ⇒ 21 increased by 2g
increased by means +
So, we have
21 increased by twice Gail's height ⇒ 21 + 2g
Hence, the expression represented by 21 increased by twice Gail's height is 21 + 2g
