The answer is D., 5040. We can solve this by using the formula for permutations, with n = 7 and r = 7.

$\frac{7!}{(7-7)!}$ =
= $\frac{7!}{(0)!}$ = 0! is equal to 1
=7!=
=5040.

pantera1 [17]

Brung like terms together:-
1/4 y - 1 3/4 y + 11/2 + 2 - 12
= - 1 1/2 y + 11/2 - 10
= - 1 1/2y - 9/2

If you deposit $6000 into an account paying 6.5% annual interest compounded quarterly, how long until there is $12600 in the acc

grandymaker [24]

Use this formula:

K = K_0 * (1+r)^n

Insert and solve for n:

12600 = 6000 * (1+0.065)^n

n = 11.78

So about 12 quarters.

Hope that helped.

briana house is at (1,6) and jordan house is(5,3) what is one possible path from brianna house to jordan house

Maurinko [17]

Answer:

see the explanation

Step-by-step explanation:

Let

A (1,6)------> location Brianna's house on a map

B (5,3)------> location Jordan's house on a map

we know that

One possible path from Brianna's house to Jordan's house it's a straight line ( the shortest distance)

using a graph tool

see the attached figure

<em>Find the distance points AB</em>

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$d_A_B=\sqrt{(3-6)^{2}+(5-1)^{2}}$

$d_A_B=\sqrt{(-3)^{2}+(4)^{2}}$

$d_A_B=\sqrt{25}$

$d_A_B=5\ units$

The distance from Brianna's house to Jordan's house is 5 units
