Answer:
Base of each triangular face = 4 inches
Height of each triangular face = 6 inches
Step-by-step explanation:
The length of each side of the square base is the base of each isosceles triangle forming the pyramid.
We know from our problem that the ratio of the height of each triangle to its base is 3:2, so . We also know that the base is a square with sides 4 inches long, since the bade of the square is the base of the isosceles triangle, .
Replacing the value of the base in our proportion:
Multiply both sides by 4
We can conclude that he base of each isosceles triangle is 4 inches and its height is 6 inches.
Solution (part 1-original): a=8 cm^2, b=3 cm^2, c=15 cm^2
Step by step solution:
The way you find area of a parallelogram is base times height so in A it would be 2x4 so 8 cm^2. You need to add the unit and have it squared to show that it’s representing a 2d space instead of a length
Solution (part 2-enlarged): a=32 cm^2, b=16 cm^2, c=60cm^2
Step by step solution (part 2):
It’s basically the same as before except that you multiply the side lengths by 2 BEFORE multiplying the height and base. So a would be (2x4)x(2x2) or 8x4=32.
I got 24 as the answer to ur question
The x coordinate of the vertex will be the average of the two zeros, here -3 and 5, so x=(-3+5)/2 = 1, f(1)=(1+3)(1-5) = -16.
Answer: (1, -16)
Let's do it some other ways. How about completing the square to turn f in to vertex form?
f(x) = (x+3)(x-5) = x² - 2x - 15 = (x² - 2x + 1) - 1 - 15 = (x-1)² - 16
and now we can read off (1, -16) as the vertex.
The other method is the vertex is x= - b/2a = - (-2)/2(1) = 1.
Three methods, same answer. Good.
Answer:
2.5 or
Step-by-step explanation:
5 x = 2.5
This is because half () of 5 is 2.5
2.5 as a fraction is .
Hope this helps!
