Answer: A. The volume of the pyramid on the left side is greater by 8in.
Step-by-step explanation:
Pyramid Volume = lwh/3
8 * 8 * 6 = 384
384/3 = 128
The volume of the left triangle is 128.
4 * 9 * 10 = 360
360/3 = 120
The volume of the right triangle is 120.
128 - 120 = 8
Answer:
- w = 8
- x = 8√2
- y = 8√2
- z = 16
Step-by-step explanation:
A 45-45-90 right triangle is isosceles. That means both legs are the same length, and its hypotenuse is √2 times the leg length. You can figure these facts using trigonometry or the Pythagorean theorem, or you can rely on your memory of them.
w = 8 . . . . . . . . . . . same as the leg length shown
x = y = 8√2 . . . . . hypotenuse of smaller triangle; both legs are the same
z = (8√2)√2 = 16 . . . . hypotenuse of larger triangle
3 3/10= 33/10
33/10
-7/10
_______
26/10=2 6/10=2 3/5= 2.60
Inequality can be used to find the domain of f(x) is x ≥ -
f(x) =
for real f(x)
4x + 9 ≥ 0
⇒ x ≥ -
Thus, Inequality can be used to find the domain of f(x) = is x ≥ -
