Free answers is right thx i got all right
WHat are your answers?
We would be happy to check your answers : )
Yo im about to take the test and ill come back with the answers for yall.
All this wrong wtf 😭
well im pretty sure the test questions get changed? so your most likely not gonna have the exact same test as the people on here, like i posted those answers and they were 100% right for me. I recommend using the mathway calculator thats how I got the 100.
It's possible that the test questions vary for different students, so some answers might not be correct for everyone. The best way to ensure that you get the correct answers is to understand the material and practice solving problems on your own. It's not worth cheating or relying on others for answers, as it won't help you learn and could have consequences.
Questions are different for everyone since you guys are so slow to understand. If your gonna cheat might as well do it right!
How is the graph of y equals negative 2 x squared minus 5 different from the graph of y equals negative 2 x squared?
The graph of y = -2x^2 is a downward-facing parabola with the vertex at (0,0), while the graph of y = -2x^2 - 5 is also a downward-facing parabola but it is shifted 5 units down from the original graph, meaning the vertex is now located at (0,-5).
A model rocket is launched from a roof into a large field. The path of the rocket can be modeled by the equation y equals negative 0.06 x squared plus 9.6 x plus 5.4 where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground.
How far horizontally from its starting point will the rocket land? Round your answer to the nearest hundredth.
A. 4.30 m
B. 160.56 m
C. 161.12 m
D. 13.94 m
To find how far horizontally the rocket will land, we need to find the x-intercepts of the equation, which represent the distance traveled when the rocket hits the ground (i.e., when y = 0). So we can set y = 0 in the equation and solve for x:
0 = -0.06x^2 + 9.6x + 5.4
Multiplying both sides by -100 to eliminate the decimal:
0 = 6x^2 - 960x - 540
Factoring out 6:
0 = 6(x^2 - 160x - 90)
Using the quadratic formula to solve for x:
x = [ -(-160) ± sqrt((-160)^2 - 4(1)(-90)) ] / (2*1)
x = [ 160 ± sqrt(25600 + 360) ] / 2
x = [ 160 ± sqrt(25960) ] / 2
x ≈ 161.12 or -1.12
Since the distance can't be negative, the rocket will land approximately 161.12 meters from its starting point on the roof. Therefore, the answer is (C) 161.12 m.

Graph the set of points. Which model is most appropriate for the set?
(negative 6, 0), (negative 4, 2), (negative 3, 3), (2, 8)
A. a coordinate plane with points plotted that form a linear graph with positive slope; points are located in the first, second, and third quadrants.
B. a coordinate plane with points plotted that form a quadratic graph; points are located in the first, second, and third quadrants.
C. a coordinate plane with points plotted that form a quadratic graph; points are located in the first, fourth, and third quadrants.
D. a coordinate plane with points plotted that form a linear graph with positive slope; points are located in the first, fourth, and third quadrants.
1. To find the number of real-number solutions of the equation -7x^2 + 6x + 3 = 0, we can use the discriminant b^2 - 4ac, where a = -7, b = 6, and c = 3:
b^2 - 4ac = 6^2 - 4(-7)(3) = 84
Since the discriminant is positive, there are two distinct real-number solutions. Therefore, the answer is (B) two solutions.
2. To find the number of real-number solutions of the equation -8x^2 - 8x - 2 = 0, we can again use the discriminant:
b^2 - 4ac = (-8)^2 - 4(-8)(-2) = 64
Since the discriminant is positive, there are two distinct real-number solutions. Therefore, the answer is (B) two solutions.
3. The given set of points do not form a quadratic graph, but they do form a linear graph with positive slope. To see this, we can plot the points on a coordinate plane and connect them by a line:
```
| *
| *
| *
| *
--------+---------
|
|
```
The line passes through three quadrants: the first, second, and third. Therefore, the most appropriate model for the set is (A) a coordinate plane with points plotted that form a linear graph with positive slope; points are located in the first, second, and third quadrants.
