The volume of a right square pyramid is 80 cubic feet. If the sides of the base are doubled, but the height remains the same, wh
maksim [4K]

Answer:

  320 cubic feet

Step-by-step explanation:

The volume is proportional to the product of the area of the base and the height of the pyramid. When the dimensions of the base are doubled, the area is multiplied by 2² = 4, hence the volume of the pyramid will be multiplied by 4.

  4 × (80 ft³) = 320 ft³

The new volume of the pyramid is 320 cubic feet.

Use the Unit Circle to find the exact value of the inverse trig function.
Vedmedyk [2.9K]

Answer:

330

Step-by-step explanation:

When we are at 30 degrees on the unit circle, we are at the point (\sqrt3/2, 1/2) so if we go to -30 degrees (330 degrees), we will be at point  (-\sqrt3/2, -1/2).

Note: (cosine, sine)

Can somebody help me with my geometry?
ahrayia [7]
The slope of AC is -0.4

Proof:
In triangles ABC and DBE,
∠DBE is common to both triangles.
AB = 2DB (D is the midpoint of the interval AB)
Also, BC = 2BE (E is the midpoint of the interval BC)

Thus triangles ABC and DBE are similar in the ratio 2:1

Since, they are similar, ∠BDE must equal ∠BAC (corresponding angles in similar triangles)

If ∠BDE = ∠BAC, DE must be parallel to AC (corresponding angles are equal along parallel lines)
Thus, the slope of AC = the slope of DE
Thus, the slope of AC is -0.4

What is the value of i^n if the remainder of n/4 is 2?
nydimaria [60]

Answer:

C and D

Step-by-step explanation:

i=√-1

n/4=x.5

since 2 is the remainder

n=2x

then i^n=i^2x

when x is even, i^n =1

when x is odd, i^n=-1
