Answer:

The answer to your question is:  \sqrt[4]{2^{3} } + 1

Step-by-step explanation:

\frac{1}{\sqrt[4]{2- 1}}  x \frac{\sqrt[4]{2^{3}}+ 1 }{\sqrt[4]{2^{3}} + 1}                       = [tex]\frac{\sqrt[4]{2^{3}}+ 1 }{2 - 1}  

                    = \sqrt[4]{2^{3} } + 1

A 37 foot board must be cut into two parts. The longer part is one foot larger than the twice the shorter part. How long is each
Rus_ich [418]

Answer:

12 ft  and 25 ft

Step-by-step explanation:

a part is x ft and the other is (2x+1) ft

so 37= x  + 2x+1

   37= 3x+1

  -1        -1

   36= 3x

    :3     :3

   x= 36:3

  I=  x= 12 ft

 II= 2x+1=2*12+1=25 ft

What is the sum of the arithmetic sequence 151, 137, 123,..if there are 26 terms?
ElenaW [278]
First term: a1 = 151
common difference: d = -14 (we decrease by 14 each time, eg, 151-14 = 137)

nth term of this arithmetic sequence is...
an = a1+d(n-1)
an = 151+(-14)(n-1)
an = 151-14n+14
an = -14n+165

This will be used in the formula below

Sn = n*(a1+an)/2
<span>Sn = n*(151+(-14n+165))/2
</span><span>S26 = 26*(151+(-14*26+165))/2 ... replace every n with 26
</span>S26 = -624

The final answer here is choice C) -624

The given line passes through the points (-4,-3) and (4,
Harlamova29_29 [7]

Answer:

Step-by-step explanation:

first we gotta find the slope of the first line

(-4,-3),(4,1)

slope = (y2 - y1) / (x2 - x1) = (1- (-3) / (4 - (-4) = (1 + 3) / (4 + 4) = 4/8 = 1/2

so the slope is 1/2.....so we are looking for a line that is perpendicular....perpendicular lines have negative reciprocal slopes...all that means is flip the slope and change the sign....so the slope we need is :

1/2....flip it....2/1.....change the sign....-2.....we need a -2 slope

y - y1 = m(x - x1)

slope = -2

(-4,3)...x1 = -4 and y1 = 3

now sub

y - 3 = -2(x - (-4) =

y - 3 = -2(x + 4) <=====
