What is the length of the line segment in the x-y plane with end points at (-2,-2) and (2,3)?

Ber [7]

You've got a formula. If the two endpoints are $A(x_A,y_A)$ and $A(x_B,y_B)$ , then the length is $\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}$ . The result is $\sqrt{16+25}=\sqrt{41}$ .

aliina [53]

Answer:
GCF = 12

for the values 144, 180, 240, 300

Solution by Factorization:

The factors of 144 are: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144

The factors of 180 are: 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

Tanisha and Rebecca are signing up for a new cell phone plan to only charge for the number of minutes and everything else includ

xeze [42]

Answer:

see the explanation in the procedure

Step-by-step explanation:

The complete question is

Tanisha and Rebecca are signing up for the new cellphone plans that only charge for the number of minutes and everything else is included in a monthly fee. Their plans are as follows:

Tanisha s Plan: $0.15 per minute used talking and a $25 monthly fee

Rebecca s Plan: $0.10 per minute used talking and a $18.50 monthly fee

After how many minutes will the two plans charge the same amount?

Let

x ----> the number of minutes

y ---> the total charge in dollars

we know that

Tanisha s Plan

$y=0.15x+25$ -----> equation A

Rebecca s Plan

$y=0.10x+18.50$ -----> equation B

To find out after how many minutes will the two plans charge the same amount, equate equation A and equation B

$0.15x+25=0.10x+18.50$

solve for x

$0.15x-0.10x=18.50-25$

$0.05x=-6.5$

$x=-130\ min$

therefore

They will never pay the same amount , because the time cannot be a negative number.

Rebecca s Plan is better than Tanisha s Plan because it has smaller fee and less cost per minute

A rule for creating a pattern is given below.

leonid [27]

Answer:

(any real number, 5)

Step-by-step explanation:

Well given that y=7-2 and that y=5, we do not know the value of x, therefore x could be any real number with y being 5. I'm pretty sure that answered your question. So, a example of an ordered pair that would fit this rule would be say (5,5) or (7,5)

Sarah is making strings of beads in the first string she uses 3 beads and she triples the number of beads in each of the next st

xenn [34]

Answer:

She uses 243 beads for the 5th string.

Step-by-step explanation:

In this problem, we can see a pattern. If she triples the number of beads in each of the next strings, that means that we just take the last number and multiply by 3. If the first string uses 3, then:

The second uses 9, 3 * 3 = 9

The third uses 27, 9 * 3 = 27

The fourth uses 81, 27 * 3 = 81

And the 5th uses 243, 81 * 3 = 243.
