Answer:
233.3 cubic units
Step-by-step explanation:
Volume of a pyramid
× base area × height
The volume of the pyramid
= 233.3 cubic units (rounded to the nearest tenth)
The lowest common denominator of 2, 4, 8 is 2 because is the smallest number that can divide all three numbers without any residue.
Answer:
1

Answer:
Option A , (0, 20); y equals one over eighty times x squared plus 20
Step-by-step explanation:The equation of parabola is given by
(X-h)^2 = 4p(Y-k)^2
In this case h = 0
So we get
Y = X^2/4P +k
Focus point is (h, p+k) , p+k = 40
Hence h, k = (0,20)
P = 40-k = 20
Equation Y = X^2/80 +20
Hence, option A is correct

Answer:
0.0707 cm
Step-by-step explanation:
We can solve this using pythgaoras theorem:
a² + a² = c² (We can use the same letter, a, because the lengths are the same length; a² + a² = 2a²)
2a² = 0.1² (simplify the right side; 0.1 × 0.1 = 0.01)
2a² = 0.01 (0.01 ÷ 2 = 0.005)
a² = 0.005 (square root both sides)
a = 0.070710... ≈ 0.0707 cm
Hope this helps!
