Answer:
5229 mm³
Step-by-step explanation:
Volume of square pyramid
b = base length = 25 mm
H = height
We have to find 'H' using Pythagorean theorem,
slant height (hypotenuse) = 28 mm
leg₁ = base length ÷ 2 = 25÷2 = 12.5
leg₂ = H
H² + (12.5)² = 28²
H² = 784 - 156.25
= 627.75
H = 25.01 mm
= 5229 mm³
Answer:
(-2, 3)
Step-by-step explanation:
In the form ...
y -k = a(x -h)^2
the vertex is (h, k).
Your equation has k = 3, a = -1, h = -2, so the vertex is ...
(h, k) = (-2, 3)
