Answer:
-82
Step-by-step explanation:
Maybe you want the determinant of ...
![\left[\begin{array}{cc}5&9\\8&-2\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D5%269%5C%5C8%26-2%5Cend%7Barray%7D%5Cright%5D)
The determinant of a 2×2 matrix is the difference of the products of elements on the down diagonal and the up diagonal:
D = (5)(-2) -(8)(9) = -10 -72 = -82
The determinant of this matrix is -82.
Let
x-------------> pounds of granola-----------> <span>$3 per pound
</span>y-------------> pounds of raisins-----------> $2 per pound
z------------ > price per <span>pounds of the trail mix
</span>
we have that
z=3x+2y--------------------- > this is the equation
for x=3 pounds of granola and y=<span>0.75 pounds of raisins
z=3*3+2*0.75=</span>$10.5 of <span>trail mix</span>
Answer:
130°
Step-by-step explanation:
Arc QPN is formed by angle QNT. Angle QNT is formed by an intersecting tangent and chord meaning arc QPN is two times the measure of angle QNT.
65° · 2 = 130°
