Someone please help me with problem #7 !!!
ser-zykov [4K]

Answer: b and d

Step-by-step explanation:

Since the roots are x=2 and x=6, we can write the equation as

f(x)=a(x-2)(x-6)

Substituting in the coordinates of the vertex,

-4=a(4-2)(4-6)\\\\-4=-4a\\\\a=1

So, the equation is f(x)=(x-2)(x-6)

On expanding, we get f(x)=x^2 - 8x+12

What is the common ratio between successive terms in the sequence
wel
Let a₁ , a₂ , a₃ , a₄ ,... .be a given sequence.
The common ratio of this sequence is the following:
 a₂/a₁ = a₃/a₂ = a₄/a₃ = r

Example: 5, 25, 125, 625, ...The common ration  is:
 25/5 = 125/25 = 625/125 = 5. So r=5 is the common ratio

Answer:

849.24 cm²

Step-by-step explanation:

we know it is a cube so to find the surface area of each square you do

12x12=144 and there are 5 sides so 144x5=720

We know sides of the squares are 12 cm so half of that (6) would be the bottom of the triangle

Now using pythagorus you would do a²+b²=c²

15²+6²=c²

225+36=c²

√261=√c²

16.15=c       this only half of one of the sides of the pyramid so you would times 16.15 by 8 to equal 129.24

now add 720+129.24=849.24 cm²
