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>

The point-slope form:

We have

Substitute:

<h3>Answer:</h3><h3>point-slope form: y - 7 = 2(x - 1)</h3><h3>slope-intercept form: y = 2x + 5</h3><h3>standard form: 2x - y = -5</h3>
Answer:
99cm^2
Step-by-step explanation:
When finding an area of a triangle, you multiply base times height and then divide by 2.
In this case,
Height:11
Base: 18
So then apply the formula:

Solve (using a calculator lol)
We get 99
Don't forget units!
So the final answer is 99cm^2
Carly sold 18, Jasmine sold half that. Half of 18 is 9. 9 + 18 = 27.
Together they sold 27 rolls of wrapping paper.
1. 15*13=195
2. 7*13=91/2=45.5
3. 7*13=91/2=45.5
4. 195+45.5+45.5=286 units squared
hope this helps!
