What is the distance between A and B? Round your answer to the nearest tenth. A coordinate plane is shown. Point A is located at

o-na [289]

$\bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
A&({{ 1}}\quad ,&{{ 5}})\quad 
% (c,d)
B&({{ 4}}\quad ,&{{ 1}})
\end{array}\qquad 
% distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}
\\\\\\
AB=\sqrt{(4-1)^2+(1-5)^2}\implies AB=\sqrt{3^2+(-4)^2}
\\\\\\
AB=\sqrt{9+16}\implies AB=\sqrt{25}\implies AB=5$

Patty measured the elementary school and made a scale drawing. The scale she used was 7 centimeters = 1 meter

Verdich [7]

Write the scale of the drawing as a fraction. Put the shorter length in the numerator.

$\frac{7 \: cm}{1 \: cm} \\$

First convert the denominator to the same units as the numerator. Write an equivalent fraction with centimeters in the denominator. Since 1 meter is equal to 100 centimeters, multiply the denominator by 100 to get centimeters in the denominator.

$\frac{7 \: cm}{100 \: cm} = \: \frac{7}{100} \\$

Write the scale factor as a ratio, using a colon

7/100 → 7:100

The scale factor is 7:100.

Guess the rule and add the next number in the sequence.<br> 1, 5, 13, 25, 41, ?

WINSTONCH [101]

Suspect: we start adding 4, later 8, 12, 16...

Therefore, the next number is 41 + 20 = 61.

Now, we try to guess the rule.

Note that, the numbers that we add are multiples of 4. Try to write the sequence in a different way like this:

1, 1 +4, (1+4) +8, ((1+4)+8)+12, (((1+4)+8)+12) +16, ...

1, 1+4, 1 + 4(1+2), 1 + 4(1+2+3), 1+ 4(1+2+3+4)...

You must to know that 1+2+3+...+ n = n(n+1)/2

Then, the nth numbers of the sequence must to be 1 + 4n(n+1)/2 = 1+2n(n+1) = a_n

Check the formula:

n = 0 then a_0 = 1+ 0

n=1 then a_1 = 1 +2(2) = 5

n=2 then a_2 = 1 +2(2)(3) = 13

n=3 then a_3 = 1 +2(3)(4) = 25

n=4 then a_4 = 1 +2(4)(5) = 41

n=5 then a_5 = 1 +2(5)(6) = 61

....
