Answer:
<h3>9.9s</h3>
Step-by-step explanation:
First note that the river is on the ground level. The height of the river at the ground level is 0
Given the the height h above the river in feet of water going over the edge of the waterfall is modeled by h(t)=-16t^2+1552
When h = 0
0 = -16t^2+1552
16t^2 = 1552
t² = 1552/16
t² = 97
t = √97
<em>t = 9.9secs</em>
<em>Hence the time it takes is 9.9secs to the nearest tenth</em>
The intersection with the y axis occurs when x = 0.
We have then:
For f (x):
For g (x):
We can observe in the graph that when x = 0, the value of the function cuts to the y axis in y = -3
For h (x):
Therefore, the graph with the intersection with the largest y axis is h (x)
Answer:
the greatest y-intercept is for:
C. h(x)
The range is 10 to 40 and then the rest .

Answer:
Option (C)
Step-by-step explanation:
Cost of ordering the number of shirts is represented by the function,
f(x) = 12.75x + 3.5
where x = number of players in the bowling team
Since number of players a bowling team can have,
6 ≤ x ≤ 10
Therefore, domain of the function: 6 ≤ x ≤ 10
For x = 6,
f(6) = 12.75(6) + 3.5
= 80
For x = 7,
f(7) = 12.75(7) + 3.5
= 92.75
For x = 8,
f(8) = 12.75(8) + 3.5
= 105.5
For x = 9,
f(9) = 12.75(9) + 3.5
= 118.25
For x = 10,
f(10) = 12.75(10) + 3.5
= 127.5 + 3.5
= 131
Therefore, for the given domain range of the function will be,
Range : {80, 92.75, 105.5, 118.25, 131}
Option (C) will be the answer.
Answer:
System of Linear Equations entered :
[1] 6x-2y=8
[2] 3x-4=y
Equations Simplified or Rearranged :
[1] 6x - 2y = 8
[2] 3x - y = 4
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = 3x - 4
// Plug this in for variable y in equation [1]
[1] 6x - 2•(3x-4) = 8
[1] 0 = 0 => Infinitely many solutions
