N^2+100=20n<br><br> Please show work
adell [148]
Subtract 20n from both sides of the equation.
n^2+100-20n=0
factor using the perfect square rule.
(n-10)^2=0
set the n-10 equal to 0.
n-10=0
add 10 to both sides of the equation.
n=0

PLEASE HELP! find the inverse matrix​
Sauron [17]

Answer:

see explanation

Step-by-step explanation:

The inverse of a matrix A = \left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right] is

A^{-1} = \frac{1}{ad-bc} \left[\begin{array}{ccc}d&-b\\-c&a\\\end{array}\right]

If ad - bc = 0 then the matrix has no inverse

A = \left[\begin{array}{ccc}11&-5\\3&-1\\\end{array}\right]

ad - bc = (11 × - 1) - (- 5 × 3) = - 11 - (- 15) = - 11 + 15 = 4 , then

A^{-1} = \frac{1}{4} \left[\begin{array}{ccc}-1&3\\-5&11\\\end{array}\right] = \left[\begin{array}{ccc}-0.25&0.75\\-1.25&2.75\\\end{array}\right]

tanθ × 240 = H

θ =( tan∧-1) 240

= <u>1.566 deg</u>
