For the first one, it's (a^8b^6). For the second one, it's 81m^8n^20.
Answer:
A. 
Step-by-step explanation:
The given parabola has vertex at (2,-5).
The equation of this parabola in vertex form is given by:
, where (h,k)=(2,-5) is the vertex of the parabola.
We substitute the values to get:
The graph passes through; (0,3).
Hence the equation of the parabola is
We expand this to get:
Since the outward region was shaded, the corresponding inequality is
The correct answer is A
Answer:
B
Step-by-step explanation:
Because usually scientific notation ends with a 10 and then an exponent
Answer:
49m/s
59.07 m/s
Step-by-step explanation:
Given that :
Distance (s) = 178 m
Acceleration due to gravity (a) = g(downward) = 9.8m/s²
Velocity (V) after 5 seconds ;
The initial velocity (u) = 0
Using the relation :
v = u + at
Where ; t = Time = 5 seconds ; a = 9.8m/s²
v = 0 + 9.8(5)
v = 0 + 49
V = 49 m/s
Hence, velocity after 5 seconds = 49m/s
b) How fast is the ball traveling when it hits the ground?
V² = u² + 2as
Where s = height = 178m
V² = 0 + 2(9.8)(178)
V² = 0 + 3488.8
V² = 3488.8
V = √3488.8
V = 59.07 m/s
