278 is the answer because I calculated it
Check the picture below.
recall that the trajectory of an object flying is, it goes up up up, reaches a maximum height and then down down down, till it hits the ground, when it happens it's not longer above ground, thus height = 0.
Answer:
Step-by-step explanation:
Let 
be the point.
Any point on y-axis is (0, y, 0)
So, distance is
= 
= 
......(1)
Now any point on x-z plane is 
Distance from p to this point is
= 
= 
.........(2)
Equating (1) and (2), we get
This is the required equation.
Answer:
s = 32
Step-by-step explanation:
s - 12 = 20
s (- 12 + 12) = 20 + 12
s = 32
Answer:
It is one-half the area of a rectangle with sides 4 units × 3 units
Step-by-step explanation:
One side of the triangle is on the line y = 2 between points x=2 and x=6. So, that side has length 6-2 = 4.
The opposite vertex has y-value 5, so is 3 units away from the line y = 2.
The area of the triangle can be considered to have a base of 4 and a height of 3. In the formula ...
A = (1/2)bh
we find the area to be ...
A = (1/2)×(4 units)×(3 units) . . . . triangle area
__
A rectangle's area is the product of its length and width. So, a rectangle that is 4 units by 3 units will have an area of ...
A = (4 units)×(3 units) . . . . rectangle area
Comparing the two area formulas, we see that the triangle area is 1/2 the area of the rectangle with sides 4 units × 3 units.
