A regular pyramid has a regular polygon base and vertex over the center of the base.
Answer:
Step-by-step explanation:
The volume of a cube is
V=s^3, we are told the volume is 10u^3 and that it will be filled with cubes having a side of 1/2 so
n(1/2)^3=10, where n will be the number of these small cubes
n(1/8)=10 upon multiplying each side by 8
n=80
So it will take 80 cubes of side length 1/2 to have a volume equal to 10u^3
I’m pretty sure it’s the last one
Answer:
vertex = (- 3, - 8 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = - 4(x + 3)² - 8 ← is in vertex form
with (h, k) = (- 3, - 8 ) ← vertex
Answer:
n = -1
Step-by-step explanation:
Use the equation y=mx + b
m (slope) = -2
x (x coordinate) = -4
y (y coordinate) = 7
You are solving for b.
Plug in for the given values:
7 = -2(-4) + b
7 = 8 + b
-1 = b (Minus both sides by 8)
y= -2x -1
Therefore, n = -1
