Two points I see on here are (0,0) and (5,300) so to get from 0 to 5 you go up by 5 and then to get from 0 to 300 you go up by 300. And then do change in y over change in x. So the change in y is how many you went up by on the y coordinate. So it’s from 0 to 300 so it’s 300. And then change in x is how much you went by in the x-coordinate so here it’s going to be up by 5 on the x coordinate. So now take the change in y which is 300 and divide by change in x which is 5 and 300/5 is 60 so the rate of change is 60. Hope this helps!!! Mark as brainliest!!

A 16-ounce of shampoo cost $4.69. What is the price per ounce, rounded to the nearest cent
elixir [45]

Answer:

A, 0.29

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.

Given the following diagram, find the missing measure.
madam [21]

m3 = 110°

Step-by-step explanation:

m1 = 180° - m4 ( sum of angles in a straight angle )

m1 = 180° - 150° = 30°

m3 = 180° - (m2 + m1) ← sum of angles in a triangle

m3 = 180° - (40 + 30 )° = 180° - 70° = 110°
