Answer:
10
Step-by-step explanation:
Ground level is where h = 0, so solve the equation ...
h(x) = 0
-5(x -4)^2 +180 = 0 . . . . substitute for h(x)
(x -4)^2 = 36 . . . . . . . . . . divide by -5, add 36
x -4 = 6 . . . . . . . . . . . . . . positive square root*
x = 10 . . . . . . add 4
The object will hit the ground 10 seconds after launch.
_____
* The negative square root also gives an answer that satisfies the equation, but is not in the practical domain. That answer would be x = -2. The equation is only useful for time at and after the launch time: x ≥ 0.
Answer:
$54
Step-by-step explanation:
To get x which is the 20% tip
1. 45×20 = 900
2. 900÷100=9
3. 9 is the tip
To get the total cost, you would have to add $9 to $45 which is $54.
Answer:
The solution to the pair of equations is
Step-by-step explanation:
The given equations are:
To solve the pair of equations graphically, we need to graph the two equations. Their point of intersection is the solution to the pair of equations.
The functions are in the form;
where m=6 is the slope and b=-4 is the y-intercept of .
and where m=5 is the slope and b=-3 is the y-intercept of .
The two equations have been graphed in the attachment.
They intersected at (1,2).
The solution to the pair of equations is
Question 1:
The answer is A: Sam.
His table is the only one that follows the conditions set in the question.
Question 2:
Choosing two points; (0, 14) and (4, 10)
Slope (m) =
= -1
Thus, equation,
I'm getting that for my equation of the line, so my best guess is that the answer is C.
The reason I got my answer is probably because I made a calculation mistake somewhere. If you use my methods, you should arrive at the correct answer.
The answer is C. ( I believe )
