When an object is dropped on the moon, it travels approximately 0.8t^2 meters in t seconds. suppose an astronaut drops a moon rock from a height of 2 meters. find the speed of the rock after 1 second.

1.6 meters per second.

Step-by-step explanation:

We have been given an position function and we are asked to find the speed of the rock after 1 second.

Derivative of this function will give us speed function.

Now let us find derivative when t=1,

Therefore, the speed of the rock after 1 second will be 1.6 meters per second.  

none cuz there are no "following statements" regarding the question

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
