Answer:
The height of the ball after 3 secs of dropping is 16 feet.
Step-by-step explanation:
Given:
height from which the ball is dropped = 160 foot
Time = t seconds
Function h(t)=160-16t^2.
To Find:
High will the ball be after 3 seconds = ?
Solution:
Here the time ‘t’ is already given to us as 3 secs.
We also have the relationship between the height and time given to us in the question.
So, to find the height at which the ball will be 3 secs after dropping we have to insert 3 secs in palce of ‘t’ as follows:
h(3)=160-144
h(3)=16
Therefore, the height of the ball after 3 secs of dropping is 16 feet.
Answer:
We have the measures:
1023 cm
2.3 m
8.72m
6430 mm
1200 mm
6.4 cm
2.5m
0.06km
Now let's write all those measures in the same unit, let's use meters.
We know that:
1cm = 0.01m
1mm = 0.001m
1 km = 1000m
Then, we can rewrie the measures as:
1023 cm = 1023*0.01 m = 10.23 m
2.3 m
8.72m
6430 mm = 6430*0.001 m = 6.430 m
1200mm = 1200*0.001 m = 1.2 m
6.4 cm = 6.4*0.01m = 0.064 m
2.5m
0.06km = 0.06*1000km = 60m
Then the order, from smallest to largest is:
6.4 cm
1200mm
2.3 m
2.5m
6430 mm
8.72m
1023 cm
0.06km
The digit in the ten millions place of a number that is less than 55,000,000 but greater than 25,000,000 can be 3 or 4.
25,000,000 < <u>3</u>5,000,000 < 55,000,000
25,000,000 < <u>4</u>5,000,000 < 55,000,000
Answer:
is the second answer 2x+1/x-1
