Answer:
<h2><em>ΔE =12.3 - (-9.6) which is equivalent to 21.9 feet </em></h2>
<em />
Step-by-step explanation:
Give the distance covered by Vivian at the bottom of the elevation to be -9.6 feet and the distance covered by Vivian at the top of the elevation to be 12.3 feet, Vivian's change in elevation will be expressed as the difference in the elevation at the bottom and the elevation at the top.
Let the initial elevation Ei = -9.6 feet
Final elevation Ef = 12.3 feet
Change in elevation ΔE = Ef - Ei
Change in elevation ΔE =12.3 - (-9.6)
Change in elevation ΔE = 12.3 + 9.6
Change in elevation ΔE = 21.9 feet
<em>Hence the expression to represent Vivian's change in elevation from -9.6 feet at the bottom of the Ferris wheel to 12.3 feet at the top is </em><em>ΔE =12.3 - (-9.6) which is equivalent to 21.9 feet </em>

Answer:
Option C - Perfect square trinomial.
Step-by-step explanation:
Given : Polynomial 
To find : What pattern is represented by the polynomial?
Solution :
First we make the polynomial in factor form,
Polynomial 
Since, it is not factor clearly so try to make the square.
Taking 4 common,

Identifying the x and y terms in the identity,

Factor the perfect square trinomial,
Therefore, The pattern polynomial represent is perfect square trinomial.
So, Option C is correct.

Step-by-step explanation:
Answer:
-1 5/8
Step-by-step explanation:
Let the total amount in the bowl be x;
If on Day 1, the volume of water in the bowl decreases by 7/8 cup, the remaining water will be;
x - 7/8
If on day 2, the volume in the bowl decreases by 3/4 cup, the remaining volume of water after the second day will be;
= x - 7/8 - 3/4
= x - (7-2(3))/8
= x - (7+6)/8
= x - 13/8
This shows that the total change after the two days is -13/8
As a mixed fraction;
-13/8 = -1 5/8
