Answer:n=-2 or n=4

Step-by-step explanation:

Q is not inversible if det(Q)=0

$\left|\begin{array}{ccc}6&7&-1\\3&n&5\\9&11&n\end{array}\right| =0\\\\\\\\6(n^2-55)-3(7n+11)+9(35+n)=0\\\\n^2-2n-8=0\\\\\Delta=36=6^2\\\\n=\dfrac{2-6}{2} =-2\ or\ n=\dfrac{2+6}{2}=4\\$

*Find the area of the figure below. Use 3.14 for pi.<br><br> Area= square inches

alex41 [277]

Answer:

100.26

Step-by-step explanation:

You would find the area of the semi circles on either side of the rectangle by plugging the diameter into the formula for the area of a circle. Then you would add that to the are of the rectangle.

This is what that would look like:

1. Divide 6 (the diameter) by 2 because $r=\frac{1}{2} d$

$r=\frac{1}{2} 6$

$r=3$

2. plug into the formula $A=\pi r^{2}$

$A=\pi 3^{2}$

3. square the 3

$A=\pi 9$

4. multiply 9 by 3.14 (pi)

$A=28.26$

This means the area of both the semi circles added together would equal 28.26

Then you would use the formula $A=lw$ to find the area of the rectangle

1. plug in the numbers given

$A= 12$ · $6$

2. solve

$A=72$

Then add the area of the semicircles to the area of the rectangle

$A=28.26+72$

to get the area of the entire figure:

$A=100.26$

Answer:

Step-by-step explanation:

The answer to this problem should be the 4th one.

All real numbers can't be right as 0 obviously wont work. However, it is important to remember that sqrt of a number cant be negative, so x must either be greater than or equal to -1 and 1
