A set of perpendicular lines form 90 degrees. We can see a 90 degree “square” in the image formed by FJ and GH.
So the answer is choice C) FJ and GH

Write each sequence as a function.

Fiesta28 [93]

Answer: $f(n)=3^{n-1}$

Step-by-step explanation:

Given Recursive formula : $a_{n+1} = 3a_n,$ , $a_1=1$

Then, $a_2=a_{1+1} = 3a_1=3(1)=3$

$a_3=a_{2+1} = 3a_2=3(3)=9$

$a_4=a_{3+1} = 3a_3=3(9)=27$

We can write it as : $f(n)=3^{n-1}$

such that

n $f(n)=3^{n-1}$

1 $f(1)=3^{1-1}=1$

2 $f(2)=3^{2-1}=3^1=3$

3 $f(3)=3^{3-1}=3^2=9$

Hence, the required function: $f(n)=3^{n-1}$

Civil engineers believe that W, the amount of weight (in units of 1000 pounds) that a certain span of a bridge can withstand wit

chubhunter [2.5K]

Answer:

x ≥ 117

Step-by-step explanation:

Let suppose Pₙ denoted the structural damage that is probable with n cans

Pₙ = P {X₁+ ....... + Xₙ ≥ w}

= P {X₁+ ....... + Xₙ-w ≥ 0 }

So weight of the ith can denoted by Xi

From CLT , ΣXi is normal with 3n and variance 0.09

w is independent of Xi and normal

ΣXi-w is also normal

then mean and variance are

E [ ΣXi - w] = 3n -400

Var (ΣXi-w) = var (ΣXi) +Var (w)

= 0.09n +1600

So Pₙ = P{ X₁ +X₂ +.... +Xₙ -w-(3n-400) /underroot 0.09n +1600 ≥ -(3n-400)/ understoot (0.09n +160v)

this can be simplified to≈ P₀ { Z ≥ 400 - 3n / undersoot (0.09n+1600)}

P{Z ≥ 1.28 } ≈ .1

on simplifying x ≥ 117

Which expression represents the prime factorization of 84?

Maurinko [17]

Hello,

The answer would be "2^2*3*7".

Reason:

The prime factorization of 84 is 84:

Therefore wrote in a expression would equal....

<span>2^2*3*7

2^2=4

4*3=12

12*7=84

If you need anymore help feel free to ask me!

Hope this helps!
