Answer:

d=\sqrt{52}

d \approx 7.211

(If you want the simplified form of the exact distance (line 1):

\sqrt{52}=\sqrt{4}\sqrt{13}=2\sqrt{13}.

Step-by-step explanation:

A is at (-6,-5).

We are given A' can be found by inserting A s point into:

T(x,y)   ->(x+4,y+6)

T(A)     ->(-6+4,-5+6)

T(-6,-5)->(  -2  ,   1   ).

So we need to find the distance between A and A'; that is find the distance between (-6,-5) and (-2,1).

The distance formula is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}.

So we need to find the change in x; the difference between the x's.  I like to obtained the positive difference for x and y when doing distance formula.  It absolutely does matter which way you do your x's and which way you do your y's as long as you subtract them.  The reason is because of the square.

The x-difference is= (-2)  -   (-6)  = -2  + 6=4.

The y-difference is= (1)   -    (-5)  =   1  +  5=6.

Back to the distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

d=\sqrt{(4)^2+(6)^2}

d=\sqrt{16+36}

d=\sqrt{52}

d \approx 7.211

Galina-37 [17]
<span>c. 4.6
       
21 X .22= 4.6
       
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.</span>

Stevens bank account balance was $212 at the beginning of the month he withdrew $63,$74 and $39 he also deposited $105 and $86 w
Natali5045456 [20]

Answer:

$227

Step-by-step explanation:

First we can add up the withdrawals(63, 74, and 39) which is 176. We can then subtract 176 from 212 to get 36.

So, after the withdrawals Steven has 36 dollars.

We can add the deposits together to get 191. We can then add 191 to 36 to get 227.

A clothes shop has some special offers. ?

The normal price of a T-shirt is £7.40 The normal price of a jumper is £9.80.

T-shirts are buy one get one free Jumpers are 3 for 2.

How much does it cost to get 5 jumpers and 2 T-shirts using this offer as appropriate?

The cost of 2 T-shirts since it is a buy 1 get 1 free => £7.40

The cost of 5 jumpers =
