NASA launches a rocket at t=0 seconds. Its height, in meters above sea-level, as a function of time is given by h(t)=−4.9t2+121t

Alenkasestr [34]

NASA launches a rocket at t = 0 seconds. Its height, in meters above sea-level, as a function of time is given by

$h(t)=-4.9t^2+121t+283$

The sea level is represented by h = 0, therefore, to find the corresponding time when h splashes into the ocean we have to solve for t the following equation:

$h(t)=0\implies-4.9t^2+121t+283=0$

Using the quadratic formula, the solution for our problem is

$\begin{gathered} t=\frac{-(121)\pm\sqrt{(121)^2-4(-4.9)(283)}}{2(-4.9)} \\ =\frac{121\pm142.083778...}{9.8} \\ =\frac{121+142.083778...}{9.8} \\ =26.8452834694... \end{gathered}$

The rocket splashes after 26.845 seconds.

The maximum of this function happens at the root of the derivative. Differentiating our function, we have

$h^{\prime}(t)=-9.8t+121$

The root is

$-9.8t+121=0\implies t=\frac{121}{9.8}=12.347$

Then, the maximum height is

$h(12.347)=1029.99$

1029.99 meters above sea level.

A chef planning for a large banquet thinks that 2 out of every 5 dinner guest will order his soup appetizer he expects 800 guest

Masteriza [31]

Answer:

320 cups of soup

Step-by-step explanation:

2/5= x/800

2/5 =.04

800*.04 =320 x=320

2/5 = 320/800

2/5 =0.4 is equivalent to 320/800=0.4

So, y-intercept is (0,3) and x-intercept is (3/7,0)

Step-by-step explanation:

We are given:

$y=-7x+3$

We need to find y-intercept and x-intercept

Finding y-intercept

To find y-intercept we put x =0

Solving:

$y=-7x+3\\y=-7(0)+3\\y=3$

So, y-intercept is (0,3)

Finding x-intercept

To find x-intercept we put y =0

Solving:

$y=-7x+3\\0=-7x+3\\-7x=-3\\x=-3/-7\\x=3/7$

So, x-intercept is (3/7,0)

So, y-intercept is (0,3) and x-intercept is (3/7,0)
