Write an explicit formula for an, the nth term of the sequence 31, 37,43, ....

Mathematics
1 answer:
Alchen [17]3 years ago
6 0

Answer:

The formula for the nth term of this sequence is: 31 + (n-1)X6

Step-by-step explanation:

This is an arithmetic sequence (ie. each term is the last term with a fixed value added to it).

T1 =31

T2 = 37 = T1 + 6 = 31 + 6

T3 = 43 = T2 + 6 = 31 + 6 + 6 = 31 + 6X2

…

In general, the nth term is 31 + 6(n-1)

Please help me to solve this ∫ 1/(x + √x) dx
skad [1K]

Answer:

\boxed{2ln (\sqrt{x}  + 1 ) + c}

Step-by-step explanation:

\int\limits {\frac{1}{x + \sqrt{x} } } \, dx

= \int\limits {\frac{1}{\sqrt{x} (\sqrt{x}  + 1 )} } \, dx

= \int\limits {\frac{2}{(\sqrt{x}  + 1 )} } \, d(\sqrt{x}  + 1 )

= 2ln (\sqrt{x}  + 1 ) + c

Two angles of a triangle have equal measures, but the third angle's measure is 82° . Find the measure of each angle of the trian
Nonamiya [84]

Answer:

Step-by-step explanation:

Two angles each  =x because both are equal.

All triangles have angles adding to 180 degrees

The angle that isn't = x is 82 degrees.

x + x + 82 = 180              Subtract 82 from both sides

2x + 82 - 82 = 180 - 82  Combine

2x = 98                            Divide by 2

2x/2 = 98/2

x = 49

angle 1 = 49

angle 2 = 49

angle 3 = 82
