Answer:
y= 704.5x - 409
Step-by-step explanation:
Complete question is : . Complete the equation for the relationship between the altitude and number of hours.
SOLUTION
By plotting altitude on y-axis and time or duration of travel on x-axis of the graph, we will have the the location of Nour at t = 0 will be represented by (0, -409)
when t = 2 hours location points will be at (2, 1000).
As you know, at a constant rate her altitude is increasing , we will have a linear graph with equation y = mx + b --> eq(1)
Slope of the line is given by:
m= (y-y') / (x-x') => (1000+409)/(2-0)
m= 704.5
y-intercept 'b' is -409
Therefore, the eq(1) will become
(1)=> y= 704.5x - 409
Where, 'y' represents Nour's altitude(in meters) relative to sea level after 'x' hours
Answer:
40%
Step-by-step explanation:
The concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original. An increase of 5 percent would indicate that, if you split the original value into 100 parts, that value has increased by an additional 5 parts. So if the original value increased by 14 percent, the value would increase by 14 for every 100 units, 28 by every 200 units and so on. To make this even more clear, we will get into an example using the percent increase formula in the next section.
Answer:
Least to greatest #1 - 0.3, 0.35, 0.5, 0.53, 3.5
Least to greatest #2 - 9.6, 9.67, 9.7, 9.76, 19.6
<em>Least meaning the lowest/smallest number.</em>
<em>Greatest meaning the highest/ biggest number.</em>
The answer is A. -3x2 - 6x - 7
