Answer:
0
Step-by-step explanation:
The slope is zero because if you put it on a graph the line looks like this

Hope this helps!
And also if the equation is like x = 4 the slope would be undefined.

Answer:
After 11 weeks, Darnell′s savings account will have a total of $8,360.
Step-by-step explanation:
The data provided is as follows:
n: 1 2 3 4
f (n): 260 360 460 560
Consider the data for f (n).
The series f (n) follows an arithmetic sequence with a common difference of 100 and first term as 260.
The nth term of an arithmetic sequence is:
Compute the value of f (11) as follows:
Thus, after 11 weeks, Darnell′s savings account will have a total of $8,360.
Answer:
a) h(t) = -16t² + 56t; b) the graph is attached; c) maximum height is 49 feet, it takes 1.75 seconds to reach the maximum, and it is in the air for 3.5 seconds.
Step-by-step explanation:
Equations for these situations are in the form
h(t) = -16t² + v₀t + h₀, where t is the tie in seconds, v₀ is the initial velocity and h₀ is the initial height. The initial height in this case is 0, since it is launched from the ground; and the initial velocity is 56. This gives us the function
h(t) = -16t² + 56t
The graph is attached.
Using the graph, we can trace the function to the maximum. The y-value of the maximum, or the maximum height, is 49 feet. The x-value of the maximum, the time it takes, is 1.75 seconds.
The roots of this equation are at x = 0 and x = 3.5. This means the rocket is in the air for 3.5-0 = 3.5 seconds.
