Answer:
A. 4.5 ft
B. 4 ft
C. 1 ft
Step-by-step explanation:
If you pretend that h is replacing y and d is replacing x and you would graph the equation, then you would get a parabola that opens down.
You would need to find the vertex of the parabola. The ordered pairs would be (d, h) instead of the normal (x, y).
A. The maximum height will be the h value of the vertex
B. Let h = 0 and solve the equation for d. That will give you distance from the stump that the frog landed.
C. The distance from the log at the maximum height is the d value of the vertex
So, that is what is needed to be done.
Without me going thru all the work, the vertex is (1, 4.5) and the solutions to the equation when h = 0 are 4, -2 (discard -2 since a distance cannot be negative)
So the answer to A is 4.5 ft.
The answer to B is 4ft.
The answer to C is 1 ft.
Now, can you find the vertex on your own and can you solve the equation when h = 0? I hope so. OK?
Answer:
200 ft²
Step-by-step explanation:
Each face is an isosceles right triangle with a hypotenuse of length 10 ft. The area of each of those triangles is
A = 1/4·h² . . . . where the h in this formula is the hypotenuse length
So, the area of the four faces (the lateral area of the pyramid is 4 times this, or ...
A = 4·1/4·(10 ft)² = 100 ft²
Of course, the base area is simply the area of the square base, the square of its side length:
A = (10 ft)² = 100 ft²
So, the total area is the sum of the lateral area and the base area:
total area = 100 ft² +100 ft² = 200 ft²
_____
If you think about this for a little bit, you will realize the pyramid must have zero height. That is, the slant height of a face is exactly the same as the distance from the center of an edge to the center of the base. "Not drawn to scale" is a good description.
