A line with a slope of 6 passes through the points (8,h) and (5,

LenaWriter [7]

$\bf (\stackrel{x_1}{8}~,~\stackrel{y_1}{h})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-8}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-8-h}{5-8}=6\implies \cfrac{-8-h}{-3}=6 \\\\\\ -8-h=-18\implies -8+18=h\implies 10=h$

What’s the square root of 13 to the nearest integer

Marianna [84]

Answer:

4

Step-by-step explanation:

First off, integers are Whole Numbers (1,2,3,4, etc), so we are rounding the answer to the nearest whole number.

The square root of lets just say 25 means you are finding a number that multiplied by itself will equal 25 (the answer is 5).

Now for 13, there is no perfect square, however the closest whole number that multiplied by itself to 13 is 4.

4*4= 16

3*3=9

5*5=25

As you can see above 4 is the closest number to 13.

Now, the ACTUAL value of the square root of 13 is 3.60555128, but we are rounding up to the nearest whole number which is 4 :)

. Approximate each of the following logarithms to four decimal places. Use the LOG key on your calculator rather than logarithm

Free_Kalibri [48]

Answer:

$log_2(6)=2.584$

Step-by-step explanation:

Here the logarithm has base 2

$log_2(3^2)=log_2(6)$

Let

$log_2(6)=x$

$log_ya=x\\\Rightarrow y^x=a$

$\\\Rightarrow 2^x=6$

Now, take logarithm to the base 10

$log 2^x=log6\\\Rightarrow xlog2=log6\\\Rightarrow x=\frac{log6}{log2}\\\Rightarrow x=2.584$

So, $log_2(6)=2.584$

The length of a rectangle is 5cm less than twice the width. The perimeter is 44cm.

Veronika [31]

Answer:

Width = 9

Length = 13

Step-by-step explanation:

width = w

length = L

w(2) - 5 = L

w + w + L + L = 44

44 + 5 + 5 = 54

54/6 = 9

9(2) = 18 - 5 = 13

w = 9

l = 13

Check:

9 + 9 + 13 + 13 = 44

9(2) = 18 - 5 = 13
