It is a 2 out of three chance of getting a composite number because that means that it is not odd. There are 10 odd numbers between 1 and 30 (2,3,5,7,11,13,17,19,23,29) and that means that there is a 20 out of 30, or 2 out of 3 chance taht the number will be composite.
Answer:
The rocket ship reaches of height of 600 feet at t=8.415
Step-by-step explanation:
First, plug in the values you know. f(t) is equal to 600, the amount of feet at time t. The vertical velocity and initial heights should also be plugged in. You should end up with an equation that looks like:
600 = -16t^2 + 200t +50.
Simply use the quadratic formula to solve for t. You'll get two answers, one negative and one positive. Choose the positive one, as the negative answer is impossible to answer a real life time problem.
The answer is 8.415.

Answer to break even, cost = earnings= $455, number of miles to cover is 11
Step-by-step explanation: cost =422+3x, where x= number of miles covered
Earnings=400+5x
St break even, cost = earnings, then solving the linear equation, by collecting like terms, and dividing through by 22. x=11, the Pu x=11 in the either the cost or earnings expressing to get 455
