Answer:

B) AB is parallel to CD, but AD is not parallel to BC.

Step-by-step explanation:

The options are:

A) AD is parallel to BC, but AB is not parallel to CD.

B) AB is parallel to CD, but AD is not parallel to BC.

C) AB is parallel to CD, and AD is parallel to BC.

D) AD is not parallel to BC, and AB is not parallel to CD.

AB and CD have the same slope, so they are parallel.

BC and AD have different slopes, so they are not parallel.

Therefore, the answer is B.

Answer:

Length of third side is: $\mathbf{8m^3-4m^2+3m}$

Step-by-step explanation:

Perimeter of triangle = $18m^3+2m^2-m$

Length of side 1= $5m^3+3m^2-2m$

Length of side 2= $5m^3+3m^2-2m$

We need to find length of third side.

The formula used is: $Perimeter \:of\:triangle=Sum\:of\:all\:sides$

Putting values and finding length of third side.

$Perimeter \:of\:triangle=Sum\:of\:all\:sides\\18m^3+2m^2-m=5m^3+3m^2-2m+5m^3+3m^2-2m+Length\:of\:3rd\:side\\18m^3+2m^2-m=5m^3+5m^3+3m^2+3m^2-2m-2m+Length\:of\:3rd\:side\\18m^3+2m^2-m=10m^3+6m^2-4m+Length\:of\:3rd\:side\\Length\:of\:3rd\:side=18m^3+2m^2-m-(10m^3+6m^2-4m)\\Length\:of\:3rd\:side=18m^3+2m^2-m-10m^3-6m^2+4m\\Length\:of\:3rd\:side=18m^3-10m^3+2m^2-6m^2-m+4m\\Length\:of\:3rd\:side=8m^3-4m^2+3m$

So, Length of third side is: $\mathbf{8m^3-4m^2+3m}$

Find the first 5 terms in the sequence an = 2n - 1

JulsSmile [24]

Answer:

1, 3, 5, 7, 9

Step-by-step explanation:

$a_n = 2n - 1$

n = 1:

$a_1 = 2(1) - 1 = 2 - 1 = 1$

n = 2:

$a_2 = 2(2) - 1 = 4 - 1 = 3$

n = 3:

$a_3 = 2(3) - 1 = 6 - 1 = 5$

n = 4:

$a_4 = 2(4) - 1 = 8 - 1 = 7$

n = 5:

$a_5 = 2(5) - 1 = 10 - 1 = 9$

Answer: 1, 3, 5, 7, 9

Use this formula to find all the solutions of the equation. (Round terms to four decimal places)

Misha Larkins [42]

I might be misreading something here but if:

x^5+243=0 subtract 243 from both sides

x^5=-243 raise both sides to the 1/5 power (or take the fifth root of both sides)

x=-3

So there is only one solution, x=-3

A self-serve frozen yogurt store sells servings up to 12 ounces. It charges $0.50 per ounce for a serving between 0 and 8 ounces

True [87]

Answer:

p(w) - - - - - - p = 0.5w ; for 0 < w ≤ 8

p(w) - - - - - - p = 4 ; for w < 8 and w ≤ 12

Step-by-step explanation:

Price, p of weight of a toughurt serving :

p(w) - - - - - - p = 0.5w ; for 0 < w ≤ 8

p(w) - - - - - - p = 4 ; for w < 8 and w ≤ 12
