What is Sn for the arithmetic series in which a1=16 , an=98 and n =13?

N76 [4]

Answer:741

Step-by-step explanation:

Given

First term $a_1=16$

last term $a_n=98$

and no of terms $n=13$

And sum of n terms is given by

$S_n=\frac{n}{2}[a_1+a_n]$

$S_n=\frac{13}{2}[16+98]$

$S_n=\frac{13\times 114}{2}$

$S_n=13\times 57$

$S_n=741$

Sp sum of n terms is 741

What is the surface area of the triangular prism shown?

Luba_88 [7]

Answer:

Step-by-step explanation:

we need to find the surface area of the shapes before adding them together. the triangles are 6*4 and since there are two, we do not need to divide by 2. (normally to find the area of a triangle it is base times height divided by 2)

so the area of the triangles are 24 units. Next we have the outer rectangles. 7*5=35. Since there are 2, we multiply by 2. Last we have the middle rectangle. 7*6=42.

the whole equation would be: 24+70+42= 136

so your answer would be B: 136.

hope this helps :)

Substitute $u=\ln x$ , so that $\mathrm du=\dfrac{\mathrm dx}x$ . The integral is then equivalent to

$\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\int\frac{\mathrm du}{u^p}=\begin{cases}\dfrac{u^{p+1}}{p+1}+C&\text{for }p\neq1\\\\\ln|u|+C&\text{for }p=1\end{cases}$

Then transforming back to $x$ gives

$\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\begin{cases}\dfrac{\ln^{p+1}x}{p+1}+C&\text{for }p\neq1\\\\\ln|\ln x|+C&\text{for }p=1\end{cases}$
