A square pyramid has a height of 12 units and a volume of 256 units3. If a square prism has the same the base area and volume as
Juliette [100K]

Answer:

4 units

Step-by-step explanation:

The volume of a square pyramid is (a²)*h/3

256=a²*12/3

256=a²*4

256/4=a²

64=a²

a=8

Now we know that the square is 8 by 8.

The volume of a square prism is a²h

256=64h

256/64=h

h=4

Also, a square pyramid is 1/3 the volume of a square prism.

12÷3=4

Find p(2) and p(4) for the function p(x) = 6x4 + 4x3 – 3x2 + 8x + 15.
gulaghasi [49]

Answer:

p(2) =147 and p(4) = 1791

Step-by-step explanation:

We are given p(x)= 6x^4 + 4x^3 – 3x^2 + 8x + 15.

Now we need to find value of p(2) and p(4)

Put x =2,

p(2) = 6(2)^4 + 4(2)^3 – 3(2)^2 + 8(2) + 15

p(2) = 6(16)+4(8)-3(4)+8(2)+15

p(2) = 96+32-12+16+15

p(2) = 147

Now put x = 4

p(4) = 6(4)^4 + 4(4)^3 – 3(4)^2 + 8(4) + 15

p(4) = 6(256)+4(64)-3(16)+8(4)+15

p(4) = 1536+256-48+32+15

p(4) = 1791

Please help with these. I will give you brainlist
ser-zykov [4K]

Answer:

Step-by-step explanation:

3. slope of CB = rise/run = 5/12      BF = 5    CF = 12

BF ⊥ DF

DB (seg of two farthest points) = √BF²+DF² = √5²+32² = √1049 = 32.4

4. f(x) = 2x² - 5x -3      vertex : A (h,k)  for f(x) = ax² + bx +c

h = - b/2a = - (-5 / 4) = 5/4

f = f(h) = 2*(5/4)² - 5*(5/4) - 3 =25/8 - 25/4 -3 = -49/8

A (5/4 , - 49/8) i.e. (1.25 , - 6.13)

negative root:   2x² - 5x -3 = (2x+1) (x- 3)      x = - 1/2      y = 0

B (- 1/2 , 0)

x coordinate of AB: 1/2 (1.25 + -0.5) = 0.375
