Answer:
x=9
Step-by-step explanation:
Subtract 2 from both sides:

square both sides, so:
x=3^2 = 9
Answer:
1/6
Step-by-step explanation:
The coin toss and the cube roll are entirely separate and independent events. To find the joint probability P(tails and 3) we need only find the probabilities of the two events and then multiply them together.
P(tails) = 0.5
P(3) = 1/6, or 0.3333 ....
Desired joint probability = (1/2)(1/3) = 1/6
Answer: Undefined or 0
Step-by-step explanation: Y=3 means there would just be a straight line across on (0,3) and when the slope and rise is 0 it means there is no slope or it is undefined
Answer:
Step-by-step explanation:
Note that the given height equation, which is a quadratic) has a graph that opens downward. Borrowing the quadratic formula, we find the roots of this equation, that is, the t values at which h(t) = 0:
The coefficients of this equation are a = -16, b = 80 and c = 0.
We need to find the roots of this quadratic. By the quadratic formula,
-(80) ±√(80² - 4(-16)(0) ) -80 ± 0
t = ------------------------------------- = ----------------- = -5/2 and -5/2 (seconds).
2(-16) -32
The initial height is 0 at t = 0 seconds and the final height 0 at 5/2 seconds.
