Answer:
3 seconds.
Step-by-step explanation:
We have been given that Sandra throws an object straight up into the air with initial velocity of 38 ft per second from platform that is 30 ft above the ground.
To find the time it will take for object to hit the ground, we will use formula:
, where,
represents initial velocity and
represents initial height.
Upon substituting our given initial velocity and initial height, we will get:

We know that object will hit the ground, when height will be 0, so we will equate object's height equal to 0 and solve for t as:

Divide by 2:

Upon using quadratic formula, we will get:






Since time cannot be negative, therefore, it will take 3 seconds for object to hit the ground.

Answer:
since .606 is higher than 5 than itd be 1 cent as in:
1 2 3 4 are below 5 so it would stay the same and numbers 56789 are 5 and higher so itd be up more
Step-by-step explanation:
Answer:
A solution curve pass through the point (0,4) when
.
There is not a solution curve passing through the point(0,1).
Step-by-step explanation:
We have the following solution:

Does any solution curve pass through the point (0, 4)?
We have to see if P = 4 when t = 0.




A solution curve pass through the point (0,4) when
.
Through the point (0, 1)?
Same thing as above




No solution.
So there is not a solution curve passing through the point(0,1).
