For the parabola:
h(t) = -at2 + bt, the maximum occurs at -b/2a
For h(t) = -16t2 + 576t that is -576/(-2)(-16), or -576/32, or 18.
The projectile is at its highest point at 18 seconds.
Answer:
Mathematician and computer scientist Katherine Johnson was born on August 26, 1918 in White Sulphur Springs, West Virginia to Joylette and Joshua Coleman. Her mother was a teacher and her father was a farmer and janitor. From a young age, Johnson enjoyed mathematics and could easily solve mathematical equations.
Step-by-step explanation:
The Fundamental Theorem of Algebra is one of the most common and most essential theorem in mathematics which states that "any polynomial degree of n will also have n roots". The degree of the equation is the highest exponent that the terms has.
In this item, if we perform the operation then, we will have a degree of 3. Therefore, the number of roots for this polynomial function is 3.
Answer:
No.
Step-by-step explanation:
An integer is a positive or negative whole number. Because -199.46 is a decimal, it is not an integer.
Answer:
Step-by-step explanation:
Given the following Quadratic equation:
The steps to solve it are:
1. Substitute into the equation:
2. Use the Quadratic formula .
In this case:
Substituting values into the Quadratic equation, you get (Round the values to the nearest hundreth):
3. The positive value is the time that the rocket will hit the ground.
Therefore, the rocket will hit the ground after .
