Someone deleted my answer so I posted it again.
Hope this helps!
5. To figure this out you must find when y = 0
-16t^2 = -200
t^2 = 12.5
Square root
t = 3.54 C
6.
Axis of symetry = -.5 (always a vertical line down vertex)
Vertex = (-.5, -6.5) (the minimum of the graph)
B
7. To find maximum height you must find the vertex
The maximum height is 549 feet after 5.75 seconds
C
9. Solve for X
x^2 = 1
Square root
X = plus or minus 1
A
Answer: The required transformation rule is given by
(x, y) -----> (-x, y).
Step-by-step explanation: We are given to write a rule that describes a transformation across the y-axis.
We know that
if a point is reflected across the y-axis, then the sign before the x co-ordinate changes.
That is, if the point (x, y) is reflected (transformed) across the y-axis, then its new co-ordinates will be
(-x, y).
Thus, the required transformation rule is given by
(x, y) -----> (-x, y).
Answer:
A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1
Step-by-step explanation:
Which statements are true? Mark all that apply. A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1. D If y³ = 16, the value of y is 2.
Solution:
a) y³ = 27
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛27
y = 3
Option A is correct
b) y³ = 64
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛64
y = 4
Option B is correct
c) y³ = 1
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛1
y = 1
Option C is correct
d) y³ = 16
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛16
y = 2.52
Option D is wrong
