Answer:
x = -1/3
Step-by-step explanation:
Answer:
Step-by-step explanation:
1) 
= 50 + (-9*8) *1
= 50 - 9.8
= 40.2 m/s
2) The acceleration of the ball at its maximum height equals to the force of gravity. -9.8 m/s²
3) The velocity at its top of the path:When the ball is thrown straight up, its velocity keeps on decreasing due the pull of gravity which pulls it towards the ground. So, the velocity at the top of its path is zero.
False is the answer hope i helped
PART AGeneral formula of quadratic equation
ax² + bx + c = 0
To find the discriminant of the quadratic equation shown above, use this following formula.
d =

There is a quadratic equation below
x² - 16x + 4 = 0
therefore
a = 1
b = -16
c = 4
Plug in the numbers to the formula
d =

d =

d =

d =

Simplify
d =

d =
The value of the discriminant is 4√15PART B
If the discriminant is less than zero (negative), the quadratic equation has imaginary solution.
If the discriminant is equal to zero, the quadratic equation has only one solution.
If the discriminant is more than zero (positive), the quadratic equation has two real solutions.
Because the discriminant of the quadratic equation is 4√15 and it's positive, <u>
the quadratic equation has two real solutions.</u>
The answer is 26 because you would look at the seven to see what to round it to and since seven is greater than five, you round the number to 26.
