Answer:
the answers are Band C
Step-by-step explanation:
B. using the number line n greater than -8
C.8=4.2
8=8
Answer:1000
Step-by-step explanation:
First we find the factors
a^3-8 is the differnce between 2 perfect cubes and is factored out to
(a-2)(a^2+2a+4)
the factors are (a-2) and (a^2+2a+4)
a^4+16
this is not factorable, unless you mistiped it and it was really a^4-16
the factor is 1
a^3+2a^2+4a
factor out the a
a(a^2+2a+4)
this is the most factored out form
the factors are (a) and (a^2+2a+4)
there are no common factors except 1 so 1 is the answer
Answer:
At 0.713 second the ball will hit the ground
Step-by-step explanation:
The height of an object t seconds after it is thrown from a height of h feet is modeled by the equation:

The ball is thrown from a point 6 feet above ground with an initial velocity, v, of 30 feet per second, equation becomes:

It is required to find the time when the ball hits the ground. At that point, h(t) =0.
So,

Above is a quadratic equation, the value of time is given by :
t = -0.526 s and t = 0.713 seconds
So, at 0.713 second the ball will hit the ground.
Okay, I got no clue what’s going on but okay
