Answer:

D 3500

Step-by-step explanation:

This question is asking for the sum of all the terms in an arithmetic series.

So using the formula : Sn = n/2 (a+l) , where Sn is the sum of n terms, a is first term, and l is last term, we try to find Sn, with n being 25, a being 20, and an which is a25 or the twenty fifth term being 260, also being the last term.

Hence we can produce the formula for Sn which is Sn=25/2 (20+260)

Sn=25/2 (280)

Vlada [557]

Answer:

Hello,

Step-by-step explanation:

$A=\begin{bmatrix}-4 & 2 \\3 & -7 \end{bmatrix}\\\\|A|=det \ A=-4*(-7)-3*2=28-6=22\\\\$

$Adj\ A= \begin{bmatrix}-7 & 3 \\2 & -4 \end{bmatrix}\\$

$A^{-1}=\begin{bmatrix}\dfrac{-7}{22} & \dfrac{2}{22} \\\\\dfrac{3}{22} & \dfrac{-4}{22} \end{bmatrix}$

d) Since A has an inverse, A is inversible and <u>not singular.</u>
