See below
Step-by-step explanation:
Answer choices:
1. The potato was launched from the ground.
-
False. 20 feet above the ground
2. The flight is symmetric about the line t = 2.
-
False. Line of symmetry is t=3
3. The potato reaches a maximum height of about 3 ft
-
False. Maximum height is about 150 ft
4. The potato is in the air during the interval 0
- Unclear. no interval given
5. The potato reaches its maximum height after about 3 seconds in flight.
6. h(2)=h(5)
- False. h(2) = 140 ft, h(5) = 80 ft
Given :
A point ( 1 ,4 ,5 ).
To Find :
The projection of the point on the xy-plane .
Solution :
Now , to find projection of a point in a plane in a plane we need to replace the coordinate of that remaining axis which is not in the plane .
Here , the plane given is xy-plane . So , remaining axis is z .
So , we replace coordinate of z =0 .
Therefore , the projection of the point ( 1 ,4 ,5 ) on the xy-plane is ( 1 ,4 ,0 ) .
Hence , this is the required solution .
Answer:
64.428
Step-by-step explanation:
well to find the mean we add all of the numbers up and then divide it by the amount of numbers in the sequence
so if we add all of the numbers up it will give us
451
then if we divide that by the number of numbers in the sequence which is 7 then that will leave us with
around 65 or exactly it would be
64.428
48? 12 times 4 is 48 and 1 part of 4 is 25%
16*3=48
12*4=48
