In order to find the surface area of a rectangle:

-- Find or measure the length of the rectangle.

-- Find or measure the width of the rectangle.

-- Make sure both quantities are in the same units.
If they're not, then convert one or the other so that they are.

-- Multiply the two numbers.

The product is the area of the rectangle, in units of
square-(the unit in which the dimensions are measured).

Find h(6) if h(x) = x2 - 2x - 5.

Alexus [3.1K]

To find h(6), we must plug in 6 into the function.

h(x) = x^2 - 2x - 5

h(6) = 6^2 - 2(6) - 5

= 36 - 12 - 5
= 36 - 17 = 19

in a AP the first term is 8,nth term is 33 and sum to first n terms is 123.Find n and common difference

allsm [11]

I believe there is no such AP...

Recursively, this sequence is supposed to be given by

$\begin{cases}a_1=8\\a_k=a_{k-1}+d&\text{for }k>1\end{cases}$

so that

$a_k=a_{k-1}+d=a_{k-2}+2d=\cdots=a_1+(k-1)d$

$a_n=a_1+(n-1)d$

$33=8+(n-1)d$

$21=(n-1)d$

$n$ has to be an integer, which means there are 4 possible cases.

Case 1: $n-1=1$ and $d=21$ . But

$\displaystyle\sum_{k=1}^2(8+21(k-1))=37\neq123$

Case 2: $n-1=21$ and $d=1$ . But

$\displaystyle\sum_{k=1}^{22}(8+1(k-1))=407\neq123$

Case 3: $n-1=3$ and $d=7$ . But

$\displaystyle\sum_{k=1}^4(8+7(k-1))=74\neq123$

Case 4: $n-1=7$ and $d=3$ . But

$\displaystyle\sum_{k=1}^8(8+3(k-1))=148\neq123$
